Eight hundred and eight subjects participated in three surveys of random samples of people aged 65 years or more living in their own homes. Neurological history and examination showed the prevalence of completed stroke to be 73 per 1000. Eighty-seven subjects per 1000 gave a history of transient cerebral ischaemic attacks. These prevalence rates were unaffected by age or sex. Senile dementia was diagnosed in 24 subjects per 1000 under 75 years and 109 per 1000 over that age. The prevalence of dementia of all types was 43 per 1000 under, and 140 per 1000, over 75 years of age. Parkinsonism was diagnosed in 16 subjects per 1000, and essential tremor in 17 per 1000. The prevalence of epilepsy was four subject per 1000. Other neurological disorders were diagnosed in 36 subjects, and a similar number had neurological abnormalities to which a definite diagnosis could not be given.

An historical review is presented of the evolution of the clinical apomorphine treatment. Some of the results from the last 10 years of psychopharmacological research have led us to the hypothesis that there exists a close relationship between abstinence and craving symptoms in drug and alcohol addicts, and that anxiety, depression, and tremor symptoms in Parkinsonism (and dementia senilis), are due to disturbances of the same, mainly dopaminergic, pathways in the CNS. In such cases, by means of effective preparations for oral use, we have utilized the synergistic effect of small amounts of apomorphine, L-dopa, and decarboxylase inhibitor with considerable therapeutic effect.

A 35-year-old patient with terminal renal failure who had received 30 mg piperazine hexahydrate/kg body weight daily for 10 days for oxyuriasis was subsequently admitted to hospital in precoma with severe clinical symptoms not unlike those observed in so-called dialysis dementia: loss of consciousness, dysarthria, apraxia, clonic spasms, tremor, muscular weakness, dropping of objects, inability to think clearly and/or hallucinations. The EEG showed disturbances with diffuse, multifocal delta waves. Under maintenance hemodialysis the patient became asymptomatic one week after discontinuation of the piperazine therapy. Piperazine is contraindicated in patients with renal failure.

An extrapyramidal disorder occurring in three generations of a family (only males) is described The clinical features were progressive dementia and extrapyramidal signs without choreiform hyperkinesia. The youngest patient (onset of disease at the age of 22 years) showed tremor, rigidity, ataxia, convulsions, and myoclonus. The neuropathologic findings were characterized by isolated symmetrical degeneration of the corpus striatum and diffuse cortical atrophy without affecting other cerebrospinal neuronal systems. The clinical features of this familial disorder and its relation to other types of familial striatal degeneration and to the juvenile form of Huntington's chorea are discussed.

A boy with mild hand tremor since age 2 1/2 was found at 4 to have cherry-red spots and mild trucal ataxia without seizures or dementia. Biochemically, he had striking hexosaminidase deficiency (serum: 4.6 percent of normal, 88.9 percent heat-labile; leukocyte: 2.2 percent of normal, 84.6 percent heat-labile; fibroblast 12.8 percent normal, 93.1 percent heat-labile). The residual hexosaminidase activity migrated electrophoretically in two bands. The major band comigrated with hexosaminidase A, the minor with hexosaminidase S. Hexosaminidase B was totally absent. The parents had partially reduced hexosaminidase with a decreased heat-stabile fraction. This disorder may result from a new mutation closely related to that causing Sandhoff-Jatzkewitz disease.

Acute encephalopathy caused by gasoline sniffing is well recognized, but has been thought to be completely reversible. We report a patient who developed a progressive encephalopathy characterized by ataxia, tremor and dementia following repeated, deliberate gasoline inhalation. Blood and urine lead levels were consistently elevated and at autopsy, the formalin-fixed brain lead content was between 5200 and 6500 micrograms/100 gm of tissue. This case shows that repeated gasoline sniffing can result in irreversible encephalopathy and that both the acute and chronic encephalopathy probably result from organic lead intoxication and not from the gasoline itself.

The authors report the cases of three men who presented for evaluation of a rapidly progressing dementia. All were found to have a giant aneurysmal mass in the basifrontal region, and all were successfully treated by surgical excision of the mass. The presenting syndrome included rapidly progressive and severe loss of recent memory associated with confusion, chronic headache, wide-based staggering gait disturbance, urinary urgency, frequency, and incontinence, and a fine tremor of the hands exacerbated by purposeful movements. The clinical presentation, radiological assessment, and surgical treatment are discussed.

Animal data indicate that serotonin (5-HT) is a major neurotransmitter involved in the control of numerous central nervous system functions including mood, aggression, pain, anxiety, sleep, memory, eating behavior, addictive behavior, temperature control, endocrine regulation, and motor behavior. Moreover, there is evidence that abnormalities of 5-HT functions are related to the pathophysiology of diverse neurological conditions including Parkinson's disease, tardive dyskinesia, akathisia, dystonia, Huntington's disease, familial tremor, restless legs syndrome, myoclonus, Gilles de la Tourette's syndrome, multiple sclerosis, sleep disorders, and dementia. The psychiatric disorders of schizophrenia, mania, depression, aggressive and self-injurious behavior, obsessive compulsive disorder, seasonal affective disorder, substance abuse, hypersexuality, anxiety disorders, bulimia, childhood hyperactivity, and behavioral disorders in geriatric patients have been linked to impaired central 5-HT functions. Tryptophan, the natural amino acid precursor in 5-HT biosynthesis, increases 5-HT synthesis in the brain and, therefore, may stimulate 5-HT release and function. Since it is a natural constituent of the diet, tryptophan should have low toxicity and produce few side effects. Based on these advantages, dietary tryptophan supplementation has been used in the management of neuropsychiatric disorders with variable success. This review summarizes current clinical use of tryptophan supplementation in neuropsychiatric disorders.

Occurrence of extrapyramidal signs was investigated in a follow-up study of 32 patients with probable Alzheimer's disease (AD). Bradykinesia and rigidity were observed in 39% and 11% of the neuroleptic-free patients at entry and in 72% and 61% at year 3, respectively. Tremor was not a predominant feature nor did its occurrence increase over time. Use of neuroleptics contributed to extrapyramidal signs; 75-100% of the neuroleptic-treated patients showed bradykinesia, rigidity or orofacial dyskinesia. The homovanillic acid (HVA) concentrations of the cerebrospinal fluid at entry were comparable to those of age-matched controls. Nor did HVA levels correlate with rigidity or bradykinesia in these early AD cases. Presence of bradykinesia or rigidity at the initial evaluation predicted more severe dementia and a poor prognosis over the period of 3 years, although interaction of initial clinical severity of dementia was significant. Of 15 patients with these signs 3 (20%) died and 8 (53%) needed institutional care, while of 17 patients without these signs only 1 (6%) died and 2 (12%) were institutionalized by year 3 (p less than 0.01).

The clinical and pathological features of a sporadic case of juvenile neuroaxonal dystrophy beginning at the age of 10 and leading to death at the age of 26 are described. Clinical manifestation began with cerebellar symptoms. The subject subsequently developed dementia, pes cavus (Friedreich's feet), epilepsy, myoclonus, and Parkinsonian syndrome, but demonstrated neither tremor nor choreoathetoid movement. Pathological examination showed typical generalized axonal dystrophy throughout the central nervous system (Seitelberger's disease). Iron-positive pigmentation was seen in the pallidonigral system, diffuse Lewy bodies (brainstem type and cerebral type) were demonstrated in the brainstem nuclei and cerebral cortex, and neurofibrillary tangles were observed.
