This work is to study the ultrastructure of the neuronal lipofuscin that occurred in the brain and the spinal cord of an autopsy case of familial Alzheimer's disease and to compare with those in several other diseases. The patient was a 46-year-old male, whose father and elder brother were diagnosed as Alzheimer's disease and died at the age of 42, respectively. He became afflicted with forgetfulness and disorientation at the age of 36. He developed a grand mal seizure at the age of 39 and thereafter, his clinical course was characterized by pyramidal signs, dysarthria and the symptoms of Gerstmann's syndrome, visuo-spatial agnosia, apraxia for dressing and constructive apraxia. He became bedridden at 45 years old and died of general prostration. The brain weighed 1,250 g, and the cerebral cortex showed mild atrophy. The neuronal loss, senile plaques and Alzheimer's neurofibrillary tangles were found throughout the cerebral cortex. The senile plaques were also found in the basal ganglia, the cerebellar medulla and cortex. There was severe amyloid angiopathy in the occipital and cerebellar cortices. The specimens for electron microscopy were taken from the cerebral cortex, the basal ganglia, the thalamus, the midbrain, the medulla oblongata, the cerebellum and the spinal cord. The ultrastructural study revealed three different types of the neuronal lipofuscin, though different stainability between these lipofuscin granules could not be manifested by several histochemical methods. Their morphological differences seemed to be based on the sites of the central nervous system.(ABSTRACT TRUNCATED AT 250 WORDS)

We developed a questionnaire for the study of background factors and quality of life (QOL) in elderly patients with cerebral vascular disease (CVD) and Parkinson's disease (PD). The questionnaire covered the background factors and four sections such as physical, functional, psychological and social health sections. Each section had 15 questions and disease-specific questions for CVD or PD were included in the physical health section. We analyzed 107 patients with CVD (76 elderly patients, aged 65 or more, 31 non-elderly patients under 65) and 136 patients with PD (91 elderly, 45 non-elderly). In the background section, of a total of 243 patients with CVD and PD, the elderly patients needed the assistance of their spouse and their sons wives more frequently than non-elderly patients. With regard to rehabilitation, non-elderly CVD patients had rehabilitation more frequently than the elderly CVD patients, while a higher percentage of elderly patients with PD had rehabilitation training more frequently than the non-elderly PD patients. In the QOL section, there was no difference between elderly and non-elderly CVD patients, while elderly PD patients were statistically more significantly disabled physically and weak-minded psychologically. The physical disabilities of the elderly PD patients in this statistical investigation included slow motion, stooped posture, frozen gait, difficulty in turning and standing up, constipation and dysuria. The psychological problems of elder PD patients included forgetfulness and a feeling of aging. These patients had significantly fewer consultations by family and relatives than the non-elderly PD patients. The overall tendency of QOL in patients with CVD and PD was similar to that of PD patients.

Vascular dementia is the second most common type of dementia. The subcortical ischaemic form (SIVD) frequently causes cognitive impairment and dementia in elderly people. SIVD results from small-vessel disease, which produces either arteriolar occlusion and lacunes or widespread incomplete infarction of white matter due to critical stenosis of medullary arterioles and hypoperfusion (Binswanger's disease). Symptoms include motor and cognitive dysexecutive slowing, forgetfulness, dysarthria, mood changes, urinary symptoms, and short-stepped gait. These manifestations probably result from ischaemic interruption of parallel circuits from the prefrontal cortex to the basal ganglia and corresponding thalamocortical connections. Brain imaging (computed tomography and magnetic resonance imaging) is essential for correct diagnosis. The main risk factors are advanced age, hypertension, diabetes, smoking, hyperhomocysteinaemia, hyperfibrinogenaemia, and other conditions that can cause brain hypoperfusion such as obstructive sleep apnoea, congestive heart failure, cardiac arrhythmias, and orthostatic hypotension. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL)and some forms of cerebral amyloid angiopathy have a genetic basis. Treatment is symptomatic and prevention requires control of treatable risk factors.
