A neurolinguistical analysis of speech by the articulation method of E. N. Vinarskaya in patients with senile dementia (4 cases) and its combination with cerebral atherosclerosis (4 cases) permitted to detect a primary "level" defect in the speech functional system. The study demonstrated a prevalent lesion of the lower, gnostico-praxis level in combination of 2 processes and prevalence of disorders of a higher, phenological (lingual)--in cases of "pure" senile dementia. A comparison of the clinical stage of the disease and the level of lesion in the speech functional system showed a possibility of an unusual (from lower to higher) destruction in patients with senile dementia with preservation of the "ordinary" regularity from the higher to lower) in memory and intellectual impairment. The detected characters of a primary speech defect in senile atrophy permitted to allocate speech disorders in such cases to genuine aphatical (focal)--the syndrome of superior-temporal area of the left hemisphere of the temporal-acoustical aphasia according to A.R. Luria. It is demonstrated that in this defect there is an involvement and disturbance of the subcortical structures as an expression of a diffusion of the destructive process.

Transient neurologic deficits are an unusual presentation of chronic subdural hematoma. Presented herein are three patients with transient aphasia and right-sided sensory-motor abnormalities caused by subdural hematoma. Review of the literature revealed 32 cases similar to ours. Presenting complaints were aphasia (77%), sensory symptoms (57%), headache (48%), hemiparesis (50%), and visual disturbance (3%). Fifteen patients underwent cerebral angiography; only three showed significant carotid atherosclerosis. Electroencephalograms were performed in seven patients; five revealed lateralized slowing, but none showed epileptiform activity. Drainage of the hematoma was uniformly curative, although six patients had transient postoperative symptoms. Patients presenting with transient deficits require imaging to rule out the presence of a chronic subdural hematoma.

Etiology, neuropsychological deficits, aphasia type, and recovery were retrospectively studied in 254 young adults with stroke. Cardiac embolism was the most common cause of stroke in patients younger than 40, while atherosclerosis was the most frequent etiology among those aged 41-50 years. In 166 aphasic patients, Broca's aphasia was the most common while Wernicke's and transcortical aphasias were rare. Compared with an older aphasic population, young patients had significantly more nonfluent aphasias and fewer comprehension deficits. These differences were related to stroke localization: the majority of infarcts localized by computed tomography in 37 patients involved either the entire middle cerebral artery territory or its superior or deep branches, explaining the preponderance of nonfluent aphasia. Prognosis of aphasia in our patients was better than has been reported for non-age-selected aphasia populations. Roughly one third of our patients recovered completely, one third improved, and one third had an unresolved language deficit. Complete recovery and significant improvement were observed even greater than 6 months after stroke. In some patients, recovery was much better than might have been predicted from lesion site and size depicted on computed tomograms.

The author has studied 17 patients with senile dementia and its combination (in case of an underlying atrophic process) with cerebral atherosclerosis but without local pathomorphological changes. It has been found that in senile dementia the multilevel and multiaspect functional system of speech is impaired at both, a lower, phonetic, and higher speech (a phonological analysis) levels. Other findings with regard to the speech level include disturbances of programming a speech statement or internal speech (dynamic aphasia), impairment of grammatical structuring and damaged lexical choice. The above disturbances (above all programming of the internal speech) are linked with intellectual deviations and are secondary to atrophy of the frontal lobes.

Two cases of the spontaneous dissecting aneurysm (SDA) of the cervical carotid artery (ICA) were reported. Case 1: A 36 years old man was admitted with a sudden onset of right hemiparesis, aphasia and a one-week history of headache and neck pain. Serological examinations were normal. Angiography showed a severe stenosis with two intimal flaps of the left cervical ICA. Four weeks later, left STA-MCA anastomosis was performed. After six weeks from the onset, re-angiography showed the resolution of the left cervical ICA stenosis. Case 2: A 26 years old man experienced the transient monoocular blindness a week before admission. He was admitted with a sudden onset of right hemiparesis and aphasia. Serological examinations were normal. Angiography showed a postsinus tapering occlusion of the left cervical ICA. Four weeks later, left STA-MCA anastmosis was performed. After the operation, left hemiparesis improved remarkably. After two weeks from the operation, re-angiography showed the complete resolution of the left cervical ICA stenosis. As the differential diagnoses, spasm, arteritis, embolism and thrombosis with atherosclerosis were listed. But from the reason reported, we diagnosed the two cases as the resolution of the SDA of the ICA. From the previous literature, 129 cases of SDA of the ICA were reviewed and discussed about the symptom, angiographic findings and treatment. Some specific findings (high frequency of resolution, 87%, etc.) were found. SDA of the ICA occurs in the non-atherosclerotic age and causes the ischemic brain damage. SDA of the ICA should be paid more attention and will probably be identified more frequently.

Using a linguistic statistical method the speech of 14 patients suffering from senile dementia and its combination with cerebrovascular atherosclerosis was examined. A substantial diminution of the use of nouns, a relative preservance of the frequency of using verbs, and a more frequent use of adverbs, pronouns, and particles were revealed: this is characteristic of both acoustico-mnestic and sensor aphasia. It points to a greater activity of the secondary speech zones in the temporal lobe of the dominant hemisphere. It is assumed that the breakdown of the functional semantic connections between the verbs and the nouns in long-term memory forms the basis of verbal paraphasias. The indices of the lexic diversity and mean length of word demonstrate a pronounced impoverishment of the vocabulary and use of simple short words, as the dementia progresses. The substantial diminution of the frequency of using prepositions and conjunctions pointed to an impairment of the grammatical development stage in the mechanism of speech.

One hundred cases of hypertensive complications due to irregular drug-therapy were studied in medicine units of Dhaka Medical College Hospital for the period of one year from February 7, 1989 to February 6, 1990. Among those stroke had headed the list (48%) manifesting in various ways e.g. cerebral haemorrhage with focal neurological signs--hemiplegia, hemiperesis, aphasia etc. Hypertension associated with varying degrees of cardiac ischaemias and heart failure was seen in 14% and 10% cases respectively. Highest incidence of complications was seen in 1-5 years after detection of hypertension with mean age of 55 +/- 18.70 years. Out of 48 cases of strokes, smoker were 41 (75.92%). Regarding reasons of noncompliance of drugs, personal carelessness was the prominent one (47%). Among the risk-factors for atherosclerosis family history tops the list (66%). Diabetes coexists with hypertension in 13% cases. Ocular complications were seen in 06% cases of malignant hypertension with variable retinal changes.

The authors report the case of a 50 year old man admitted to hospital with a right hemiplegia and aphasia of sudden onset in whom embolic fragments were found in the left mid and anterior cerebral artery territories at left carotid angiography : transoesophageal echocardiography demonstrated a protrusive plaque of atherosclerosis in the ascending aorta and a pediculated thrombosis in the descending aorta. Biological investigations revealed a protein S level of 3% (normal : 70-140%). This case illustrates the acute development of a thromboembolic phenomenon originating from the aortic arch in a patient with a coagulation defect.

A 73-year-old man who had suffered from old myocardial and cerebral infarction for 4 years had been secured in wheelchair due to left hemiplegia and aphasia and also been received a home care of his wife. One day, his wife tied a cloth belt around his head and secured it to the wheelchair to prevent the flexion of his neck. One hour later, he was found dead by his wife. He also had slipped down in his wheelchair. The autopsy performed 24 hours after death revealed a ligature marks on the front of the neck. Petechial hemorrhages, visceral congestion and fluid blood, compatible with asphyxial death, were also found. Although severe cerebral cortical atrophy, old myocardial infarction, moderate to severe atherosclerosis and decubitus of the back were also found, they were not considered primary cause of death. No other anatomical or toxicological cause of death was present. Therefore, we concluded that the man died of accidental hanging. Recently, the home care of aged or handicapped patient is a social problem in Japan due to the increase in the number of elderly people. The death was caused by the inappropriate restraints used by his wife. This case suggests the importance of proper advice to non-professional caretakers from care professionals.

An independent, inverse association between cognitive function and all-cause mortality has been reported in elderly cohorts. The purpose of this study was to determine whether the same association exists in middle-aged persons. The Atherosclerosis Risk in Communities Study is a cohort study initiated in 1987 to investigate the development of atherosclerosis in middle-aged persons. Three cognitive function measures were included in the second cohort examination conducted from 1990 to 1992 when the participants were aged 48-67 years: the Delayed Word Recall Test (DWRT), the Digit Symbol Substitution Test (DSST) (a subtest from the Wechsler Adult Intelligence Scale-Revised), and the Word Fluency Test from the Multilingual Aphasia Examination. Cox proportional hazards modeling was used to determine whether all-cause mortality ascertained through 1997 was associated with each measure after adjustment for sociodemographic, biologic, psychologic, and behavioral risk factors. Without adjustment, there was a significantly lower mortality hazard associated with higher scores on all three measures. After covariate adjustment, the hazard ratios for the DWRT and the DSST remained significant (hazard ratio1-point DWRT score increment = 0.90, 95% confidence interval: 0.84, 0.97; hazard ratio 7-point DSST score increment = 0.86, 95% confidence interval: 0.80, 0.93). Cognitive function measured in middle age appears to have prognostic importance for life expectancy similar to that reported in elderly adults.
