Over the last 30 years, more than 400 medicines representing 447 separate indications have been approved to treat rare diseases, compared to <200,000 fewer than 10 in the 1970s. The cells are irradiated to prevent further cell growth although they stay metabolically active. Rare diseases are responsible for 35 percent of deaths in the frst year of life and 30 percent of children with a rare disease will not live to see their ffth birthday. Encouragingly, one in three of the nearly 3,000 treatments with orphan designation are for children. In addition to the Orphan Drug Act, two other laws have made a signifcant impact on pediatric research. By providing a predictable regulatory environment, the permanent reauthorization will help ensure that pediatric research by biopharmaceutical companies continues to advance children’s medical care. It targets a defective protein antibody directs the therapeutic to target the cancerous cells. Genetic markers may make it possible to identify a patient population in advance and allow clinical trials with a smaller number of participants. Before a potential new treatment can be approved, it must be tested in clinical trials.

This is not necessarily the original document that identified the case; rather erectile dysfunction frustration best purchase for silagra, it is the source that provided the most complete information sudden onset erectile dysfunction causes buy silagra 100mg without a prescription. An independent facility; a facility that is not a part of a hospital or managed care system buy erectile dysfunction pills online uk best purchase for silagra. An independent medical record containing only information from encounters with that specific facility Managed health plan what do erectile dysfunction pills look like purchase discount silagra line. Any facility where all of the diagnostic and treatment information is maintained in one unit record (all records for the patient from all departments erectile dysfunction the facts 100mg silagra fast delivery, clinics erectile dysfunction at age of 30 order silagra 100 mg on-line, offices, etc. Note: the category “physician’s office” also includes facilities that are called surgery centers when surgical procedures under general anesthesia cannot be performed in these facilities. If another source document is subsequently identified, the Type of Reporting Source code must be changed to the appropriate code in the range of 1, 2, 8, 4, 3, 5, or 6. Priority Order for Assigning Type of Reporting Source Code the source that provided the best information used to abstract the case. Example: the only patient record available for a physician office biopsy is the pathology report identified from a freestanding laboratory. When multiple source documents are used to abstract a case, use the following priority order to assign a code for Type of Reporting Source: Codes: 1, 2, 8, 4, 3, 5, 6, 7. Note: Beginning with cases diagnosed 01/01/2006, the definitions for this field have been expanded. Codes 2 and 8 were added to identify outpatient sources that were previously grouped under code 1. The source facilities included in the previous code 1 (hospital inpatient and outpatient) are split between codes 1, 2, and 8. Conversion of the old codes would be problematic and would require extensive and time-consuming review of original source documents. Further, for those abstracts, the flag will designate analytic versus non-analytic abstracts. Assign manually or automatically assign using registry software Instructions for Central Cancer Registries 1. Set the flag to 1 when any of the facilities who contributed to the consolidated data for a cancer record set the CoC Accredited Flag to 1 2.

Census Bureau, to ensure comparability of definitions of cases (numerator) and the population at risk (denominator). Census Bureau Instructions: “The place where he or she lives and sleeps most of the time or the place the person says is his or her usual home. A post office box is not a reliable source to identify the residency at diagnosis. Post office box addresses do not provide accurate geographical information for analyzing cancer incidence. Use the post office box address only if no street address information is available after follow-back. Use residency information from a death certificate only when the residency from other sources is coded as unknown. For example, the death certificate may give the person’s previous home address rather than the nursing home address as the place of residence. If the person was a resident of a nursing home at diagnosis, use the nursing home address as the place of residence. Do not use legal status or citizenship to code residence Persons with More than One Residence 1. Code the residence where the patient spends the majority of time (usual residence) 2. If the usual residence is not known or the information is not available, code the residence the patient specifies at the time of diagnosis Examples: the above rules should be followed for “snowbirds” who live in the south for the winter months, “sunbirds” who live in the north during the summer months, and people with vacation residences that they occupy for a portion of the year. Persons with No Usual Residence Homeless people and transients are examples of persons with no usual residence. Code the patient’s residence at the time of diagnosis such as the shelter or the hospital where diagnosis was confirmed. Census Bureau definition: “Persons under formally authorized, supervised care or custody” are residents of the institution. Census Bureau has detailed rules for determining residency for personnel assigned to these ships. The rules refer to the ship’s deployment, port of departure, destination, and its homeport. Codes in this field are based on the Census Boundary files from the 1990 Decennial Census. Codes in this field are based on the Census Boundary files from the 2000 Decennial Census. This code should be used for county and county-based rates and analysis for all cases diagnosed in 2000-2009. Codes in this field are based on the Census Boundary files from the 2010 Decennial Census. This code should be used for county and county-based rates and analysis for all cases diagnosed in 2010-2019. The county of the patient is unknown, or the patient is not a United States resident. State is coded according to the United States Postal Service abbreviation for the state. It is a derived (geocoded) variable based on Census Boundary files from 1970, 1980, or 1990 Decennial Census. It is a derived (geocoded) variable based on Census Boundary files from 2000 Decennial Census. It is a derived (geocoded) variable based on Census Boundary files from 2010 Decennial Census. Census Tract 2010 records the census tract of a patient’s residence at the time of diagnosis. This field allows a central registry to add year 2010 Census tracts to cases diagnosed in previous years without losing the codes in the fields Census Tract 1970/80/90 and Census Tract 2000 which are only collected historically. A census tract is a small statistical subdivision of a county that, in general, has between 2,500 and 8,000 residents. Census Bureau establish census tract boundaries and try to keep the same boundaries from census to census to maintain historical comparability, though this is not always possible. When populations increase or decrease, old tracts may be subdivided, disappear, or have their boundaries changed. Because the census tracts do change, it is important to know which census tract definition is used to code them. Codes Census tract codes 000100-999998 Special Codes Code Description 000000 Area not census-tracted 999999 Area census-tracted, but census tract is not available Blank Census Tract 2010 not coded Coding Instructions 1. Census tract codes should be assigned based on a computer match (geocoding software) 3. Census tracts are identified by four-digit numbers ranging from 0001 to 9989 and a two-digit suffix 4. Assign code 999999 when an area does have an assigned census tract but the census tract is not available 5. Add the suffix as the fifth and sixth digits if it exists; otherwise, use 00 so all six positions are coded. Census tract certainty records how the 2010 census tract was assigned for an individual record. Central registry staff should code this field manually when geocoding is not available through a vendor service. Code 5 has priority over code 9 Note: Codes 1-5 and 9 are usually assigned by a geocoding vendor, while code 6 is usually assigned through a special effort by the central registry. Assign code 1 when the census tract is assigned with certainty based on complete and valid street address 2. Cases diagnosed since 2005 are assigned a code based on the American Community Survey data that is published annually using the diagnosis year. The codes separate counties into metropolitan counties and non-metropolitan counties based on the population size, and on proximity to a metro area for nonmetropolitan counties. Codes for this data item can be derived electronically using the state and county at diagnosis. The variable can be an indicator of access to recreation, access to food stores, exposures to pollutants, crime levels, social cohesion, etc. Collecting the variable with each decennial census allows for retrospective and cross-sectional epidemiologic analysis.

Generally, the registry software program calculates the Age at Diagnosis using the Date of Birth and Date of Diagnosis 3. Age at Diagnosis can be manually calculated using the Date of Birth and the Date of Diagnosis 4. If the patient’s age is 100 years or older, check the accuracy of the date of birth and date of diagnosis, and document both in a text field Cases Diagnosed In Utero Record 000, less than one year old, for cases diagnosed in utero. Generally, registry software programs calculate the Age at Diagnosis using the Date of Birth and Date of Diagnosis. The calculation may result in a negative number for a case diagnosed in utero – replace the negative number with 000. Census Bureau as the heritage, nationality group, lineage, or in some cases, the country of birth of the person or the person’s parents or ancestors before their arrival in the United States. The five race fields (Race 1 – Race 5) make it possible to code multiple races for one person, consistent with the 2000 Census. All resources in the facility, including the medical record, face sheet, physician and nursing notes, photographs, and any other sources, must be used to determine race. If a facility does not print race in the medical record but does maintain it in electronic form, the electronic data must also be reviewed. Recommendation: Document how the race code(s) was (were) determined in a text field. Code 07 takes priority over all other codes Example: Patient is described as Japanese and Hawaiian. Code only the specific race when both a specific race code and a non-specific race code apply a. See Coding Instruction 15, Exception, for the only situation in which name is taken into account when coding race 2. Code race using the highest priority source available according to the list below (a is the highest and c is the lowest) when race is reported differently by two or more sources Sources in Priority Order a. Code the race(s) of the patient in fields Race 1, Race 2, Race 3, Race 4, and Race 5 a. Code 88 for the remaining race fields (Race 2 – Race 5) when at least one race, but fewer than five races, are reported 5. Why a particular race code was chosen when there are discrepancies in race information Example: the patient is identified as Black in nursing notes and White in a dictated physical exam. There is a statement that the patient is Hispanic or Latino(a) and no further information is available Example: Sabrina Fitzsimmons is a Latina. Code race as 02 (Black) when the stated race is African-American, Black, or Negro 8. Example: Patient is described as Asian in a consult note and as second generation Korean American in the history. Code the race based on birthplace information when the race is recorded as Oriental, Mongolian, or Asian and the place of birth is recorded as China, Japan, the Philippines, or another Asian nation Example 1: Race is recorded as Asian and the place of birth is recorded as Japan. All race fields must be coded 99 (Unknown) when Race 1 is coded 99 (Unknown) Note: Assign code 99 in Race 2-5 only when Race 1 is coded 99. Refer to Appendix D “Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics” when race is unknown or not stated in the medical record and birth place is recorded a. Exception: Code Race 1 through Race 5 as 99 (Unknown) when patient’s name is incongruous with the race inferred on the basis of nationality. Do not code the inferred race when the patient’s name is incongruent with the race inferred on the basis of nationality. When the patient face-sheet indicates “Race Other,” look for other descriptions of the patient’s race.

Surgery on supratentorial cavernomas is mainly indicated when a patient has intractable epilepsy erectile dysfunction doctor dubai purchase silagra now. The goal of the operative treatment in these patients is to alleviate the epilepsy and eliminate any future risks of hemorrhagic events erectile dysfunction hypertension drugs buy silagra 100 mg without prescription. However impotence guidelines buy silagra australia, to achieve favorable seizure outcome over the counter erectile dysfunction pills uk buy 100 mg silagra overnight delivery, some patients may just be observed and treated with proper antiepileptic drugs impotence webmd silagra 50 mg otc. This approach was reported to be effective in 60% of cases in a small series of 16 patients [52] erectile dysfunction treatment needles cheap silagra 50mg visa. Larger studies, by contrast, have confirmed more favorable seizure outcome after cavernoma resection. All patients with a single seizure before surgery were seizure-free, as were also patients who had developed seizures within two months before surgery [57]. Only 76% of those patients who had a preoperative duration of epilepsy exceeding two months were seizure-free at follow-up. In concordance with previous studies, the authors discovered that patients older than 30 years at operation have better chances for a favorable seizure outcome than younger persons. Patients with secondary generalized seizures preoperatively were significantly less likely to achieve a seizure-free state than those with simple partial and complex partial seizures (26% vs. Removal of a cavernoma in patients with intractable epilepsy should be assessed in the context of epilepsy surgery, implying indications for tailored surgery of the epileptogenic brain tissue. Failure to control epilepsy after an operation can be linked to incomplete resection and/or the persistence of a hemosiderin fringe or the development of secondary epileptogenic foci in areas remote from the primarily lesion [23]. Lesions close to limbic structures are at higher risk of forming distant loci that with time may “learn” to generate seizures independently [14]. Still, no uniform policy regarding additional resection has been suggested in the literature. Operative techniques the goal of the operative treatment of a cavernoma is gross total resection. Partial removal can significantly increase the risk of bleeding with consequent complications. Total removal of the lesion requires dissection of the lesion from the surrounding brain. Thus, if the cavernoma is located within or beside critical structures of the brain. Use of the operating microscope and microsurgical instruments is essential in cavernoma removal. Preoperative planning and mapping of eloquent areas adjacent to the cavernoma are the most important part of the surgery, as any inaccuracy in direction of approach can lead to significant difficulties in finding small lesions within parenchyma. The most precise method is to combine knowledge of anatomical landmarks in the affected region and use of stereotactic navigation (frame-based or frameless). Importantly, despite seemingly correct calculations, a neurosurgeon can become lost and fail to find a lesion. Among these are coronal and sagittal suture, external auditory meatus, nasion, and inion, as well as such intracranial structures as Sylvian fissure, sulcal and gyral key points. The first group helps to delineate the approximate location of the lesion and extrapolate it to the surface of the skull for appropriate craniotomy. In these cases, real-time ultrasonography, especially in conjunction with neuronavigation, is particularly useful for lesions that show no surface extensions [46, 165, 311, 323]. Due to achievements in radiological diagnostics and mapping, awake-craniotomy is not necessary. After craniotomy and dural opening, dissection of the cortex is performed through the overlying gyrus or sulcus. The transsulcal approach has been suggested to minimize cortical damage and to 31 expose the lesion in a “keyhole” fashion [69, 124]. Because the cortex is thicker over the crest of a convolution and thinner at the depth of a sulcus, the transgyral approach sacrifices a larger number of neurons than the transsulcal approach [249]. However, disruption of the arcuate U fibers during transsulcal exposure is not proven to be less detrimental than disruption of vertical projection fibers after the transgyral approach [124, 249, 279]. Meticulous dissection of the arachnoid with sufficiently long preparation of the vessels crossing or lying within the sulcus is crucial to avoid their over-traction, stretching, or kinking, with subsequent ischemic injury to the adjacent or remote cortex. When a patient is operated on soon after overt bleeding, entry to the hematoma provides an initial route to the lesion. Otherwise, appearance of yellowish discoloration indicates an underlying cavernoma. When the lesion is approached, the gliotic plane is identified and circumferential dissection around the lesion is performed until it is free [319]. En bloc resection is recommended, although removal in piece-meal fashion is also suitable since cavernomas do not tend to cause any major intraoperative bleeding [279]. Dural-based cavernomas in the middle fossa are an exception: they may cause profuse bleeding during resection and therefore require careful handling in terms of avoiding damage to the integrity of the nidus [319]. The resection bed should be carefully inspected under high magnification for small satellite lesions [319]. Gliotic fringe discolored by blood breakdown products should be removed only when a lesion is located out of eloquent areas. The extent of resection of perifocal hemosiderotic parenchyma still remains controversial for cure or prophylaxis of epileptic disorder. After removal of the perifocal parenchyma, precise hemostasis is performed using bipolar coagulation with minimal voltage to avoid inadvertent injury to normal vasculature. Cavernomas of the brain stem represent one of the most challenging neurosurgical pathologies requiring thorough knowledge of the functional anatomy of the region and superior dexterity of the operating surgeon. Traversing of even a very thin fringe of healthy tissue between the lesion and brain stem surface during the approach may lead to devastating deficits. Risk of postoperative deterioration may be similar to having an overt hemorrhage from cavernoma [236]. A more favorable outcome is expected when a cavernoma extends to the pial surface and myelotomy is not necessary or only minimal [236]. Summarizing their recent experience of brain stem cavernoma surgery, Garrett and Spetzler recommended a supracerebellar infratentorial or lateral supracerebellar infratentorial approach for lesions involving the posterior or posterolateral midbrain [99]. To access lesions involving the anterior or 32 anterolateral midbrain, a full or modified orbitozygomatic craniotomy is recommended [99, 177, 342]. Lateral and anterolateral pontine lesions may be safely reached using the retrosigmoid approach. A safe entry zone, located between the fifth cranial nerve and the corticospinal tracts provides a reasonable pathway to the lesion of the anterior pons. A posterior pontine and posterior medullary cavernoma abutting the floor of the fourth ventricle is best approached via a suboccipital craniotomy, whereas lateral and anterolateral medullary lesions are reached using a far-lateral suboccipital approach [99]. When a cavernoma is large and/or hemorrhage causes significant mass-effect with displacement of the tracts and nuclei, superficial anatomical landmarks, such as the facial colliculus or the stria medullaris, are not concordant with the presumed location of intrinsic structures [203]. The mechanism of response to radiosurgery is thought to be a chronic inflammatory process, including endothelial cell proliferation, vessel wall hyalinization and thickening, and eventual luminal closure with a latency interval ranging from two to three years [161]. Sex, age, and duration of epilepsy had no prognostic value, whereas extratemporal location and history of only simple partial seizures was related to better seizure outcome. Radiation-induced complications include edema, necrosis, increased seizure frequency, and recurrent bleeding [4, 133, 294]. Expectedly, greater dosimetry is associated with a higher risk of complications [231]. Many questions regarding these entities still have no answers or are under debate. To date, there is no explanation in the literature why cavernomas are commonly located supratentorially, accounting for 70% of all lesions, but affect the spine very rarely. Furthermore, what limits the size of the lesion and why gigantic lesions are extremely rare are not fully understood. The growing number of patients with incidentally found lesions tends to increase the number of patients with lesions previously considered rare. A clearer understanding of the basic pathological features and treatment results of these cases is essential when making clinical decisions and planning management adequately. Among unusual cavernomas treated at our department, we analyzed intraventricular, multiple and spinal cavernomas; we supplemented these with a literature review. Intraventricular Cavernomas Patients and symptoms Intraventricular cavernomas constitute 2. Furthermore, authors noted that incomplete surgical remove can exacerbate extensive growth after long period of being stable [5, 213, 335]. Surgical or autopsy findings suggested that such growth may be attributable to repeated intralesional hemorrhages rather than to confluence of vascular channels [213]. Improved 45 (58) Persistent deficit 18 (24) Clinical manifestations are related to the Died 8 (10) location within the third ventricle. Lesions in Not defined 6 (8) the suprachiasmatic region tend to cause visual field restriction or endocrine dysfunction, 38 whereas cavernomas involving the lateral wall or floor of the ventricle can affect short-term memory functions [181]. There are observations showing enlargement of cavernomas during pregnancy and shrinkage after delivery [335, 345]. Some authors believe that cavernomas in the third ventricle could be under stronger hormonal influences because of their location [149], but no data exist to confirm this. The location of a cavernoma in the lateral ventricle is also frequently associated with raised intracranial pressure. In 22 of 38 cases (58%) with lateral ventricle cavernomas reported in the literature, patients suffered from mass-effect and hydrocephalus as leading symptoms. These patients suffered from sensorimotor paresis in the extremities [66], drop attacks [104], diplopia and ataxia [152, 335], and dysartria [137]. All patients with fourth ventricle lesions experienced intermittent headaches frequently accompanied by nausea and vomiting. However, in one case, a lesion located in the temporal horn of the lateral ventricle caused severe intraventricular bleeding and intracerebral hematoma [226]. However, in lesions with subependymal origin, a hemosiderotic fringe could be detected [146]. Surgery is advocated when re-hemorrhages are frequent, and the mass-effect causes progressive neurological deficits. In cases of acute hydrocephalus, temporary external ventricular drainage was usually applied before surgical excision of the lesion, and in five reported cases (6%) a permanent shunt was indicated [68, 128, 149, 213, 285]. In this group, the cavernoma was in the third ventricle in four patients, and one newborn had a giant lesion in the lateral ventricle. Patients with cavernomas close to the brain stem frequently present with cranial nerve deficits. Thus, surgery on this already affected region can worsen neurological status and cause new deficits, even after minimal manipulation. However, these deficits have significant recovery potential, and many of them improve after a long recovery period [267]. Removal of a cavernoma located in the lateral ventricle may be performed via several approaches, but all through the parenchyma (Table 7). Furthermore, in anatomic investigation of the optic radiation in relation to the operative route to lesions of the trigonum, some authors recommend an interhemispheric parieto-occipital approach with a mesial entry point located anterior to the calcarine and parieto-occipital sulci and posterior and inferior to the parietal lobule [187]. By using the suggested corticotomy, the authors avoided any disruption of the optic radiation. However, neuropsychological tests assessing attention, verbal memory, and disconnection showed no correlation with any of the surgical approaches. Instead, there were correlations with preoperative clinical condition and a presumably longer or chronic history of hydrocephalus [67]. Among drawbacks associated with transcortical approaches, the most common appear to be postoperative seizures and intracerebral hemorrhage. The reported risk of postoperative seizures after transcortical approaches ranges from 29% to 70%, whereas the respective figure after transcallosal approaches is only up to 10% [13, 26, 151, 172, 352]. Lesions located in the region of the foramen Monroe and anterior third of the 41 ventricle are exposed using an anterior interhemispheric transcallosal approach, a pterional transsylvian approach [336], or alternatively, a transchoroidal transvelum interpositum or interforniceal approach [11]. Lavyne and Patterson accessed a lesion in the mid-third ventricle via a subchoroidal transvelum interpositum approach, but only partial resection could be accomplished and this patient experienced postoperative bleeding [174]. Yoshimoto and Suzuki excised cavernomas of the suprachiasmatic compartment via an interhemispheric trans-lamina terminalis approach [340]. The same approach was successfully employed for removal of foramen Monroe cavernomas by Ogawa et al. A lesion located in the posterior third of the ventricle is accessed via a median or paramedian supracerebellar suboccipital approach or a 42 posterior parieto-occipital interhemispheric approach [336]. Exposure of the fourth ventricle is usually performed via median inferior suboccipital approach. After craniotomy and dural opening, the fourth ventricle is accessed using a transvermian or cerebello-medullary fissure (telovelar) approach [336]. The latter is preferable as division of the vermis can be associated with cerebellar mutism, especially in children [233]. Neuroendoscopy To date, only one case of a successful removal of an intraventricular cavernoma by endoscopy has been reported [98]. Seven patients (10%) developed visual field deficits [8, 45, 58, 208, 212, 213, 276]. Four patients (6%) suffered from sensorimotor deficits after surgery [200, 212, 247, 285], three patients (4%) with a third ventricle lesion developed endocrinological disorders (in two transient diabetes mellitus and in one hypothyroidism) [149, 213, 285]. One newborn with a lateral ventricle cavernoma operated on at the age of two days developed hydrocephalus, and a ventriculoperitoneal shunt was placed [128]. In one case, reported by Gaab, a patient with lateral ventricle lesion had postoperative memory loss, which did not resolve during the 19 months follow-up of [98]. In total, eight patients died (10%), and, notably, five of them (7%) after surgical treatment [92, 104, 149, 285, 297]. The postmortem revealed diffuse brain edema, transtentorial herniation, and sinus thrombosis [297].

Use a diary or stick reminders in prominent places, so that you don’t forget important appointments. The occupational therapist will work with you to develop strategies to manage any diffculties you have with this. It is caused by weakness or incoordination of the muscles around the mouth, face or voice box which can make speech sound slurred, quiet, slow or indistinct. In severe cases it can make it very diffcult for your speech to be understood, even by people who know you very well. Dysphasia/aphasia Dysphasia and aphasia mean the same thing and refer to a language disorder. Some people may have diffculties in just one area but it is common to have diffculties across all areas. Aphasia does not affect intelligence, but it does make it diffcult to get messages in and out; and express your thoughts, feelings and wishes. There are many ways to help someone with aphasia and the Speech and Language Therapist will be able to advise you on what is most helpful to you or your relative. This includes using lots of strategies as well as words to help the person with aphasia understand and express themselves. Strategies to try include giving short and concise information using simple language; writing down important words, using gestures and encouraging the person with aphasia to gesture or write or draw what they are trying to tell you. Using photographs, pictures or objects such as calendars or maps may also be helpful. There are also two very helpful organisations which offer advice and support for patients and carers: Connect Tel: 0207 367 0840 If you do have diffculty swallowing you will be assessed by a Speech and Language Therapist who will advise you about the safest consistencies for eating and drinking. If it is recommended you need to alter your diet or fuids it is important you follow the recommendations, as swallowing problems or an unsafe swallow can result in food or fuids going down the wrong way into your lungs. This is called aspiration and can result in a chest infection or pneumonia which can be very serious. Coughing whilst eating or drinking or choking can be signs of swallowing diffculties. Continence It is common to experience problems regulating and controlling your bowels and bladder after a stroke. This may be due to damage in the area of the brain which controls the bowels and bladder, or due to lack of mobility. Constipation is common and may be avoided by drinking at least 8 glasses of fuid each day and increasing your intake of fbre in the form of fruit, vegetables, cereals and wholemeal bread. Should you suffer with your bowels or bladder, please do speak to one of your team. It is very common after a stroke and could have a signifcant impact on your wellbeing. Your brain is working very hard to compensate for the damage caused by the stroke, and this tiredness is normal. In fact you are recharging your energy levels to enable you to continue with your day to day activities. Emotional changes Everyone’s response to their stroke is different and it is very common to feel a range of emotions which changes over time. Feelings of anxiety and low mood are particularly common, but you may also go through periods of feeling frustration, loss, grief, sadness and denial. These are normal responses to what has happened and do not require treatment unless they become a particular problem for you. For example, buying meals to be put in the oven / microwave rather than cooking from scratch, or sharing the responsibility of your fnances with someone you trust. Emotional lability; this is an unprompted or uncontrollable tendency to laugh or cry at things, even if it is not appropriate to do so. It is estimated to affect one in four people in the frst six months after their stroke and often settles with time. Behavioural changes Some people may also experience behavioural changes after their stroke and it may seem as though they have had some change to their personality. Sometimes there is a complete reversal of character, for example a mildly mannered person becoming aggressive but more commonly existing personality traits become exaggerated. Sometimes people may become confrontational or unable to prevent themselves saying what they are thinking, even if it is unkind or hurtful. The person who has had the stroke may be unaware of these changes, and it is often their family and friends who notice it frst. It is estimated that about half of people who have had a stroke will experience signifcant depression within the frst year, and it is more common if you have communication diffculties. Depression can begin soon after the stroke or later and can range from a mild problem to something more severe. There are several reasons for depression occurring after a stroke, including the following: the physical damage to the brain can trigger depression by disrupting the electrical activity which generates and controls emotions, thoughts and perceptions. Depression may also stem from a variety of emotional reactions towards the stroke itself, such as a lasting disability or the impact on future hopes and dreams. It is important to remember that depression is an illness and not a weakness and it can have an impact on your recovery. Physical activity, no matter how gentle, can help lift your mood and ease tiredness and fatigue. The consequences of a stroke affect all members of the family; you may spend longer periods of time with each other and possibly with less sleep. Many people say they fnd they argue more in the early months after discharge from hospital. Try and share your concerns and feelings with each other, as ‘bottling things up’ will only increase your stress levels. Details of the Stroke Association and local stroke clubs can be found in the ‘Useful Contacts’ section of this booklet. As you recover, you may begin to consider your relationships with those close to you, and begin to establish or renew your sexual relationships. How you feel about yourself and how you perceive others feel towards you can lead to you losing confdence in yourself. It can take time to adjust to and come to terms with the changes in your life after a stroke and many people experience anxiety and depression as a result. Medication to treat blood pressure may cause men to have diffculty getting an erection, and this may be further enhanced by fatigue and anxiety. Physical obstacles such as having a catheter may also cause problems, as can physical disabilities such as a weakness down one side of the body. There is no reason why after a couple of weeks you cannot begin to have sex if you feel ready to do so. You can express your feelings in many different ways, through talking but also with body language and physical contact such as kissing and cuddling. Taking the frst step may be the biggest hurdle to overcome your anxiety and shyness about resuming sexual contact. You may resume driving after a month if you are deemed ft to drive by your doctor. Details of projects and organisations that can help you with returning to driving can be found in the ‘Useful Contacts’ section 4. Anticoagulation this is a process of thinning the blood so that it is less likely to clot and cause a stroke. Aspiration Can be caused by an unsafe swallow, where fuid or food enters the lungs. The top fgure is when the heart muscle contracts and the bottom fgure is when the heart muscle is at rest. Brain stem the stem-like part of the brain, which links the two halves of the brain to the spinal cord. It contains some vital nerve cells involved with breathing and many other important functions including the heart and eyes. This may involve carers coming to your home to assist with personal care, dressing, meal preparation and medication prompts as required. Carotid artery There are two carotid arteries on each side of the neck which carry blood from the heart to the head, notably to the face and the front of the brain. Carotid doppler An ultrasound scan of the carotid arteries to check blood fow to the brain. Carotid Surgical operation to remove obstructions (usually fatty tissue or a endarterectomy blood clot) from inside an artery. Cerebellum the part of the brain that controls co-ordination and fne (delicate) movement, and may also play a part in higher mental functions. Cerebrum the largest part of the brain, made up of the left and right hemispheres. Cholesterol A fatty substance made in the liver and also present in some foods, which is vital to the body’s normal functioning. If present in excess, it can be deposited in the wall of the arteries to produce fatty lumps or plaques (atheroma). A scan of the brain which can show the type of stroke that has occurred and its location in the brain. Cognition A person’s thinking processes including concentration, memory and planning skills. Arm and hand movement may appear clumsy or the sequencing (ability to do things in logical order) of a complex task may be forgotten. Goals are often broken down into stages and members of the team will work with you to help you achieve your goals. H Haemorrhagic A stroke caused by a burst blood vessel bleeding into the brain stroke (intracerebral haemorrhage). Homonymous hemianopia is the loss of the same half (either left or right) of the visual feld in both eyes. I Ischaemia An interruption of the blood supply to a part of the body, causing cell death. Multidisciplinary A team of professionals working together to help you in your team recovery. Posterior A stroke affecting the posterior (rear) artery of the brain, which Circulation Stroke can result in visual and balance diffculties. Subarachnoid Bleeding between the brain and one of the covering haemorrhage membranes, often due to a leaking aneurysm (bulge in the wall of a blood vessel). Total Anterior A blockage of the blood vessels supplying the front (anterior) Circulation Stroke part of the brain.
