A diagnosis based on the presumed mechanism of stroke onset is useful for management strategies in acute ischemic stroke. Ninety-two patients with embolic (cardiac or artery-to-artery) and 107 with non-embolic (thrombotic or hemodynamic) stroke were diagnosed on strict cerebral angiographic criteria alone. To clearly discriminate between these two groups, the neurological and computed tomographic (CT) findings were then compared. Rapidity of onset, vomiting, urinary incontinence, level of consciousness, cervical bruit, anisocoria, tongue deviation, sensory disturbance, and CT findings (location of hypodense area, findings of brain edema and hemorrhagic transformation) were discriminatory factors between the two groups (p<0.01). According to these 11 items, we prepared a numerical table for quantitative differential diagnosis. A diagnostic accuracy of 98.9% for embolic and 87.9% for non-embolic stroke in internal verification, and 90.0% and 82.9%, respectively, in external verification was observed. The differences in clinical features and CT findings between embolic and non-embolic stroke may reflect the pathophysiological mechanisms of the occlusive process of cerebral artery as well as the extent and severity of ischemia.

One hundred and ninety-nine elderly stroke patients, who received rehabilitation treatment, were examined, to clarify the relationship between cognitive function and discharge place. The patients who moved to long-term care facilities showed more severe disabilities of basic activities of daily living (ADL), more frequent incontinence, and lower functional impairments (Brunnstrom stage), compared with those discharged to their home. Multivariate regression analysis was done with discharge place as the dependent variable. Independent variables were age, sex, kind of stroke, rehabilitation period, level of ADL and IQ on Kohs test, or performance IQ on the Wechsler Adult Intelligence Scale. Older age, higher levels of ADLs, and higher scores on Kohs test IQ or Wechsler Adult Intelligence Scale Performance IQ were all significantly linked with home discharge. These results suggest that non-verbal cognitive dysfunction may affect discharge place in elderly stroke patients after rehabilitation therapy.

The characteristics of incontinent stroke patients who regained continence by the time of their discharge from an acute rehabilitation program were compared with those of patients who remained incontinent. Of the 90 patients who met the inclusion criteria on admission to the program, 45 were continent at discharge. Compared with those who regained continence, the subjects who remained incontinent at discharge took longer to be transferred to the rehabilitation program after the onset of stroke, had lower total Functional Independence Measure (FIM) instrument scores at admission and discharge, had more episodes of urinary incontinence (UI) during the first 24 hours after their admission, and had smaller increases in functional scores during rehabilitation. When the time from the onset of stroke was controlled, a subsample of those who remained incontinent scored lower only on the social cognition subscale 14-18 days after the stroke, whereas 27-30 days after their stroke their scores on the sphincter control and self-care subscales were lower. UI was not associated with patients' destinations at discharge. The results of this study provide more information about UI after stroke and give direction for future research.

Infarction in the anterior cerebral artery (ACA) territory is an uncommon cause of stroke. The clinical findings of ACA infarctions are not fully characterized but include contralateral hemiparesis, urinary incontinence, transcortical aphasia, agraphia, apraxia, and executive dysfunction. We report a patient with a large right ACA infarction, who in addition to previously reported findings also had a complete hemiplegia, profound sensory neglect, and micrographia.

Majority (90.5%) of the elderly living in the community in Singapore had a positive (satisfactory to good) perception of their health. This study found that age (70 years or older), recent hospitalisation, regular medical follow-up, hearing impairment, presence of chronic medical conditions (like musculo-skeletal problems, hypertension, ischaemic heart disease and chronic obstructive lung disease), impairment in activities of daily living, history of falls, those on regular medications and those with financial difficulties all adversely influenced perception of health. Those able to participate in regular outdoor leisure activities have a positive influence. Factors that did not significantly influence perception of health were gender, health-promoting activities, work, poor eyesight, cognitive impairment, urinary incontinence, diabetes, history of stroke and the ability to use public transport.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an increasingly recognized autosomal dominant disorder that leads to cerebrovascular manifestations in early adulthood. This study delineates the phenotypic spectrum and the natural history of the disease in 102 affected individuals from 29 families with biopsy-proven CADASIL. Recurrent ischemic episodes (transient ischemic attack [TIA] or stroke) were the most frequent presentation found in 71% of the cases (mean age at onset, 46.1 years; range, 30-66 years; SD, 9.0 years). Forty-eight percent of the cases had developed cognitive deficits. Dementia (28%) was frequently accompanied by gait disturbance (90%), urinary incontinence (86%), and pseudobulbar palsy (52%). Thirty-nine patients (38%) had a history of migraine (mean age at onset, 26.0 years; SD, 8.2 years), which was classified as migraine with aura in 87% of the cases. Psychiatric disturbances were present in 30% of the cases, with adjustment disorder (24%) being the most frequent diagnosis. Ten patients (10%) had a history of epileptic seizures. To delineate the functional consequences of ischemic deficits, we studied the extent of disability in different age groups. The full spectrum of disability was seen in all groups older than age 45. Fifty-five percent of the patients older than age 60 were unable to walk without assistance. However, 14% in this age group exhibited no disability at all. Kaplan-Meier analysis disclosed median survival times of 64 years (males) and 69 years (females). An investigation of the 18 multiplex families revealed marked intrafamilial variations.

We performed a community-based study on a cohort of 221 stroke patients followed for 3 years. In this paper, we tried to answer the following questions: Is the risk of dying increased throughout the first 3 years after stroke? What are the causes of death after the 1st month? What factors at stroke onset are independent predictors of early and late mortality? The relative risk of death was estimated using age- and sex-specific mortality rates for the Netherlands. Causes of death were registered by the attending physicians, mostly general practitioners. During the 1st month 26% of the patients died. At 1, 2 and 3 years, the cumulative mortality rates were 37, 46 and 54%, respectively. Stroke patients had an increased risk of dying, approximately twice that of the general population, during the 3 years of follow-up. In women, this increased risk was more pronounced than in men. After 1 month, cardiovascular pathology, stroke and diseases resulting from stroke were the causes of death in 70% of the patients, i.e. substantially higher than in the general population, matched for age and sex. Factors predicting mortality after stroke varied over time. Severity of the stroke, preexisting atrial fibrillation and congestive heart failure were associated with early mortality (within 30 days). For 1-month survivors, incontinence and preexisting atrial fibrillation were associated with mortality in the 1st year after stroke. After 1 year, only age was associated with mortality.

Pressure ulcer development is a serious problem occurring predominately among elderly persons, who are confined to bed or chair. Factors associated with pressure ulcer development include: cerebrovascular accident, impaired nutritional intake, fecal incontinence, lymphocytopenia and a high comorbidity score. Implementation of preventative measures, such as: in-depth assessment for mobility, a pressure relieving device combined with adequate repositioning, thorough evaluation for nutritional status and urinary incontinence, significantly reduce pressure ulcer incidence. If the pressure ulcer is a partial thickness (Stage II) wound, the causative factors are probably friction and/or moisture. If the ulcer is full thickness (Stage III, IV) it is secondary to pressure and/or shearing forces. The development of wound infection is the most common complication. Osteomyelitis is not an uncommon occurrence and must be initially ruled out in all full thickness pressure ulcers. Surgical debridement of necrotic tissue is necessary prior to further treatment and /or assessments. Cultures and antibiotic therapy are indicated only upon evidence of infection (erythema, edema, cellulitis, osteomyelitis, leukocytosis, bandemia or fever). Topical pharmacologic agents may be used to prevent or treat infection but must be carefully controlled to avoid such adverse effects as toxicity to the wound, allergic reaction and development of resistant pathogens. Proper use of occlusive dressings increase patient comfort, enhance healing, decrease the possibility of infection, save time and reduce costs. A patient presenting an ulcer which fails to improve, or due to its size will take a great deal of time to heal, should be evaluated for surgical closure.

A 54-year-old man developed somnolent akinetic mutism and acute mixed transcortical aphasia following a left thalamo-mesencephalic infarction. He also exhibited behavioural changes, namely apathy, slowness, lack of spontaneity, disinhibition, perseveration, gait apraxia and incontinence consistent with frontal lobe dysfunction. Presumably the akinetic mutism and language dysfunction were due to the thalamic stroke. All the manifestations could be related to interruption of the frontal-subcortical circuitry.

During the period from July 1995 to June 1996 we performed transurethral resection of the prostate (TURP) on 824 patients with benign prostatic hyperplasia (BPH). Among them, 13 were dementia patients between 74 and 96 years old; they presented with urinary hesitancy in 6, retention in 4, frequency in 2 and incontinence in 1 patient. Past history included stroke in 7, hypertension in 6, pulmonary tuberculosis in 4, diabetes in 3, asthma in 2, angina pectoris in 1, Parkinson's disease in 1, pneumonia in 1, and hepatitis in 1. Careful preoperative examination revealed that they were proper candidates for TURP. They underwent TURP under spinal anesthesia. The mean operative time was 34 min, ranging from 20 to 60 min. The adenoma resected weighed 24 g on the average, ranging from 7.5 to 48 g. During surgery, although hypotension was noted in 2 patients, there was no serious morbidity. Their mental condition was well controlled with ketamine and diazepam during and after surgery. Postoperative complications included acute myocardial infarction in 1, multiple gastric ulcer in 1, and decubitus in 1. None died within 3 months after TURP, 3 died there after, and 10 patients were alive at the mean follow-up period of 26 months. Six patients reported good urination, 3 reported some improvement in urination after surgery, although requiring intermittent catheterization and 1 developed mild incontinence. In conclusion, TURP appears to provide some benefit in selected patients with dementia and should not be considered to be a contraindication for such patients.
