Epidemiological investigations were carried out in an industrial plant in a population of about 16 000 people. The overall morbidity was 1 241.8 cases of nervous system diseases per 100 000 of population and the annual prevalence of neurological diseases was 473.7 per 100 000. The most frequent disease was sciatic pain, followed in order of frequency by epilepsy, vasomotor headaches, subjective symptoms after craniocerebral trauma, Parkinson's disease, clinically evident cerebral atherosclerosis and disseminated sclerosis. No significant effect of the type of occupation on the development of nervous system diseases was observed.

The cyclic alternations of wakefulness and sleep competing for the domain of brain activity are controlled by neuronal systems contained in the core of the brainstem, hypothalamus, thalamus, and basal forebrain. This organization encompasses complex neuroanatomic, neurophysiologic, and neurochemical mechanisms that are subject to disruption from within, or as a result of incidental alterations of appropriate brain centers. The first section of this article reviews the wake-sleep disturbances that occur with lesions in defined neuroanatomic structures involved in sleep mechanisms, such as the brainstem, hypothalamus, thalamus, and cerebral hemispheres. The second section gives an overview of specific sleep alterations associated with neurologic disorders. These include stroke, Parkinson's disease, degenerative systemic disorders, multiple sclerosis, myotonic dystrophy, myasthenia gravis, brain tumors, head trauma, coma, epilepsy, and headache syndromes.

There are few reports on the prevalence of headache in Parkinson's disease (PD). In the present study, 223 chronic PD sufferers and 291 controls are surveyed by a headache questionnaire. There is no significant difference in the total prevalence of headache in sex and age-matched patients and controls. However, male patients with PD have a higher prevalence of moderate to severe migraine than the control population.

In a Nigerian town with a stable population of 20,000, a door-to-door survey was conducted, using a questionnaire involving a complete census and a simple neurological evaluation which had previously showed a 95% sensitivity and an 80% specificity for detecting neurological disease. Positive responders were evaluated and categorised, using agreed criteria for diagnoses. Nearly 100% cooperation was obtained. Life prevalence ratio for at least one episode of headache was 51/1000. Crude point prevalence ratio for migrainous headache was 5.3/100, and peak age-specific ratio was in the first decade. Prevalence ratio for epilepsy was 533/100,000 and peak age-specific prevalence ratio occurred in the 5-14 years age groups. The prevalence ratio for peripheral nerve disorders was 268/100,000, and age-specific prevalence ratio for tropical neuropathy increased with age. Prevalence ratio for stroke was rather low at 58/100,000, but was probably due to the people's attitude to the disabled elderly and high mortality of stroke which showed annual mortality rate of 70/100,000 which increased with age to 1519/100,000 per year in the eighth decade. Crude prevalence ratios (cases per 100,000) for others are 112 for neurological complications (including sciatica) of spondylosis, 15 each for poliomyelitis, motor neurone disease, development speech disorders, 10 each for syncope, hereditary neuropathies. Parkinson's disease, benign essential tremor, primary cerebellar degeneration, cerebral palsy, mental retardation, organic psychosis (probable intracranial tumor) and 5 each for muscular dystrophy, pyomyositis, spina bifida occulta, alcohol dependence and cerebral malaria. The implications of the findings are important for development of community neurological services in the developing countries.

We evaluated the effect of 25 mg bid amitriptyline on muscle contraction headache in 36 patients with Parkinson's disease in a randomized double-blind placebo-controlled study. Treatment lasted 12 weeks, and we assessed the efficacy by number of days with headache, sum-of-severity score (intensity X number of days with headache), and consumption of analgesics. We also administered Hoehn-Yahr staging, the Webster Rating Scale, the Mini-Mental State, and the Zung Self-Rating Depression Scale. We assessed the patients after a 4-week run-in period and after 4, 8, and 12 weeks of treatment. Thirty-one patients (15 in the amitriptyline group and 16 in the placebo group) completed the trial. Amitriptyline reduced the intensity and the frequency of headache, whereas the placebo did not. The Zung Depression Scale and the Webster Rating Scale findings remained unchanged.

The images of cranial computed tomographies on 7.921 patients aging between 50 and 98 years were analyzed retrospectively concerning the occurrence of WMLA. 3.344 patients were suffering from psychogeriatric disorders (organic brain syndrome, dementia, depressive or delusional psychoses). Neurological diagnoses (stroke, TIA, Parkinson's disease, Huntington's disease, space occupying lesions, seizures, cerebral trauma, vertigo, chronic headache) occurred in 4.577 patients. WMLA was established in 761 cases. The combination of WMLA with cerebral atrophies, with single or multiple infarcts and with both infarcts and atrophy will be demonstrated within 4 groups: 1. organic brain syndrome and dementia, 2. depression and delusional states, 3. stroke and TIA, 4. other neurological diagnoses. In group one the combination of WMLA with atrophy and infarcts is the most common finding in CT. In group two WMLA without atrophies and infarcts are the main tissue changes in CT. Group three is marked mainly by the occurrence of recent infarcts together with WMLA. In group four again WMLA only, in some cases together with multiple infarcts, do occur mainly. Compared to the cases without WMLA in each group WMLA is seen in cases with organic brain syndromes and dementias three to five times more than in the other diagnostic groups. WMLA in computed tomography seems to be a common finding in patients and healthy individuals of old age. Therefore the diagnostic and differential diagnostic significance for brain diseases in old age is limited. Nevertheless in the field of psychogeriatric disorders it may be possess a certain value to understand the nature of such diseases. This value will be discussed and demonstrated considering the pathogenesis of WMLA on the basis of neuropathological results.

A study of neurological disorders and services is presented. The ten most common neurological diagnoses were headache, back disorders, neuropathy, cerebrovascular disease, dizziness/insomnia, myopathies, soft tissue disorder, intracranial injury, neurological symptoms (numbness, etc.), and Parkinson's disease. The pattern of diseases is similar to that reflected in the prevalence of those in the US. The annual beneficiary rate was 1.6% of the population, the median age was 45 years, and the majority (52%) served were females. There were 1.8 annual services per beneficiary and the median hospital stay was 9 days. Ambulatory care accounted for the majority (62%) of services and 64% of the inpatient services were delivered by neurosurgeons. The majority of the admissions (61%) and of the ambulatory services (55%) were provided in Regina.

One characteristic of the Limousin district is the raised average age of its population. Given the growing average age found in France and the ensuing potential problems, it was thought useful to undertake a neuro-epidemiological study of the distribution of neurological diseases in this region. The initial step involved checking the techniques to be used and the form of questionnaire relevant to this type of study. Following W.H.O. recommendations, the total population of one small town was surveyed, and the distribution of various neurological ailments was thus measured (headaches, migraine, cluster headaches: 12.73 p. 100, transient ischemic attack: 1.89 p. 100, stroke: 1.36 p. 100, epilepsy: 1.68 p. 100. Parkinson's disease 1.47 p. 100, dementia: 0.31 p. 100, misc: 0.84 p. 100). These figures were compared with the results from similar pilot projects carried out elsewhere around the world. The results obtained in this preliminary study enabled us to perfect the methods, and to perform a more extensive survey of a representative cross section of the Limousin population. This larger study will be published later.

During a long-term double-blind study, which began February 1985, we have treated 16 patients with Morbus Parkinson or Parkinson's syndrome with deprenyl or identically appearing placebo tablets. The aim of the study is to ascertain whether a reduction of other antiparkinsonian medication, especially Madopar, can be achieved with deprenyl, in order to minimize the known late undesirable collateral effects ("on-off"-phenomena, dyskinesias). The criteria used in evaluation of the course of disease are the clinical-neurological findings as well as a series of motor performance tests. The results to date indicate that the dose of Madopar could be reduced in 7 of the 16 patients. Two of these patients were receiving Madopar alone, while 5 had been given anti-cholinergics in addition. In one female patient the dose of Madopar had to be reduced due to the development of dyskinesias. It is noteworthy that the psychological condition of the patients remained constant. There was no increase in side-effects, e.g. headaches, dizziness, nausea, etc. with administration of the study substance. In 3 patients with longstanding Parkinson's disease treated with Madopar or Nacom, who were not included in the study, the doses of the above drugs could be maintained or reduced by addition of deprenyl.

Manganese (Mn) poisoning, a well-known hazard in miners and industrial workers, shares many features with Parkinson's disease. Two young agricultural workers with a parkinsonian syndrome, who mentioned exposure to the fungicide maneb (manganese ethylene-bis-dithiocarbamate), led us to investigate a new possible source of Mn intoxication. Fifty male rural workers with occupational exposure to maneb were compared with 19 rural workers without fungicide exposure. We noted significantly higher prevalence of plastic rigidity with cogwheel phenomenon, headache, fatigue, nervousness, memory complaints, and sleepiness in the exposed group. In addition, we saw other neurologic signs, such as postural tremor, cerebellar signs, and bradykinesia, although without statistical significance. The data suggest that occupational exposure to pesticides containing Mn is a possible source of Mn intoxication of the CNS.
