The author reports on 86 cases of protracted disorders - without significant changed consciousness - which he named dysthymia. The clinical manifestations were characterized by peculiar emotional disorders, polymorphous autonomic and vascular shifts. These states occurred in the majority of cases after some somatic diseases in conjunction with other physical or psychological stresses in individuals with anxiety traits and 'neurocirculatory asthenia'. The first phase of the disease was accompanied by anxiety, restlessness, autonomic and vascular paroxysms, anorexia, insomnia and disturbances of other physiological functions. Subsequently dysphoric mood, somatic concerns, pseudoneurotic and neurotic syndromes appeared. The outcome of the disorders was either with slow practical recovery or with a relatively stable personality change in the form of weakened volition, a reduction of energy, and a narrowing of the 'zone of comfort' due to the impairment of homeostatic functions. Often hypochondriasis could develop on the background of such features. Dysthymia is viewed as a special entity which must not be included either in the group of neuroses or in the group of typical organic brain syndromes, or in the group of endogenous psychoses.

Although the incidence of neurosyphilis has declined dramatically after the World War II because of the development of antibiotics, it is recently increasing a little bit. There has been few reports on the neuroimaging of general paresis. We studied a fresh case of general paresis by X-ray CT (XCT), MRI and PET scans, and report the changes of neuroimages before and after the therapy. A 38-year-old man was admitted with disorientation, thought disorder and personality change. He also had insomnia and megalomania. There were neither obvious neurological signs nor particular changes of the XCT scan abnormalities on admission. His clinical symptoms were gradually worsened within three months, when the XCT and MRI scans showed moderate brain atrophy especially in the frontal and temporal lobes with mild dilatation of the lateral ventricles. In the PET study, the cerebral blood flow was decreased in the entire brain, especially in the frontal lobes, although the thalamus and the basal ganglia had normal levels. By immunological procedures and the cerebrospinal fluid (CSF) studies, the diagnosis of general paresis was made. He was treated with penicillin G and other antibiotics. In one year after his first therapy, many symptoms vanished. Although the cerebral atrophy was a little advanced, the cerebral blood flow was dramatically increased. As far as we know, this is the first PET study of general paresis before and after penicillin treatments.

Some studies suggest that abnormal behaviors are associated with increasing cognitive loss in Alzheimer's disease (AD). Other studies do not show this association. We examined the relation of cognitive loss, represented by Folstein Mini-Mental State Examination (MMSE) score, with abnormal behaviors in 680 patients with probable AD. Six behaviors were examined: agitation/anger, personality change, wandering, hallucinations/delusions, insomnia, and depression. All but depression were associated with declining MMSE score. The number of abnormal behaviors present in each patient was also related to declining MMSE score. Several other associations were also found: hallucinations/delusions were associated with age and race; agitation/anger was related to male gender; and wandering was associated with increased age. Although these data support the general notion that five of the six abnormal behaviors studied are more likely to occur with increasing cognitive loss, the correlations are small and it is suggested that other as yet unproven factors may play an as large or greater role than MMSE score in predicting such behaviors.

The authors researched the demographic characteristics of 233 patients with methamphetamine-associated disorders, and the relation between years of methamphetamine use and symptoms of methamphetamine psychosis. The results were as follows: There were more male users than females. However there were signs that the female users were gradually increasing. Users tended to be older, but users in their 20's and 30's continued to be predominant. Their school careers were usually limited and most of them had left school at a young age. Relations with a particular social group (e.g. organized gangs) has given most of them a chance to use methamphetamine. The symptoms that were seen with high frequency at the first examination were anxiety, fretfulness, auditory hallucination, insomnia, irritability, psychomotor excitement, delusion of persecution, suspicion, delusion of reference, mistake of circumstance, loss of appetite, affective disorder, hypobulia and personality change. With these symptoms, there is a possibility that five years of methamphetamine use is the turning point in terms of the frequency of symptoms occurrence. It was suggested that affective and perceptual disorders depend on the dose of methamphetamine, but abnormalities in thought subject may be deeply influenced by the patient's "feeling of social wrong". Emotional exhilaration and euphoria decreased as the number of years of methamphetamine use increased. These phenomena may be an indication of tolerance. The symptoms that were seen with high frequency at the last examination were hypobulia, affective disorder, personality change, insomnia, anxiety and fretfulness. The symptoms that were highly resistant to treatment were hypobulia, affective disorder, personality change, general malaise, hypochondriasis, insomnia, anxiety and fretfulness. It was suggested that five years of methamphetamine use may be a turning point in the residual rate of symptoms at the last examination after treatment, and also the resistance rate to treatment. Hypobulia and personality change became more evident during treatment.

An autopsied case of Pick's disease, having an extraordinary cerebral change in the anterior portion of Lobus frontalis and temporalis, was reported. Our case is a 71 year-old woman at death with a fourteen year history of chronic progressive dementia and mental deterioration, and it may be stressed that the existence lasted 8 years, over the latter half of clinical course, was depended on the tube feeding. The first symptoms suddenly appeared in 1964, 2 months after her husband's death of illness, when she was 57. She prepared the table for breakfast late at night, calculated wrongly in her domestic account book, and stole foods in the grocery. Two years later, her illness was diagnosed as presenile dementia by characteristic personality change and marked dilatation of anterior horn of lateral ventriculus. On admission to National Musashi Sanatorium, three years after the first symptoms' appearance, she presented restless walking, insomnia, memory loss, weakness of concentration, and high degree of disorientation. Particularly, it was noticeable that she behaved with bizzare contact. After 1970, tube feeding was introduced continuously, because of swallowing difficulty. Death occurred in July 1978 from a general weakness and a broncho-pneumonia, 14 years after the onset of the first symptoms. Autopsy revealed small and atrophied brain weighed 820 g. Cerebral cortical atrophy extended to frontal, temporal, insular, and parietal lobes, but right T-1 was relatively well preserved. On section, frontal and temporal ventriculus were remarkably enlarged and caudate nuclei were extremely atrophic.(ABSTRACT TRUNCATED AT 250 WORDS)

1. We examined 156 patients 33 years after CO poisoning occurred at the Miike Mikawa Mine, Fukuoka, Japan. The subjects were classified according to age as follows: between 55 and 59 years (n = 14), 60 and 69 years (n = 62), 70 and 79 years (n = 60), and 80 and 87 years (n = 18). The mean age was 69.2 years old. Concerning the duration of coma that occurred soon after the accident, 64 remained comatose from 0 to 6 hours, 46 from 6 to 12 hours and 46 from 12 to 48 hours. 2. Subjective symptoms were observed in 96.8% of the patients. Among them, forgetfulness was noted in 89.7%, followed by irritability in 66.7%, headache in 59.6%, insomnia in 55.8%, limb pain in 46.8%, dull head feeling in 42.9% and dizziness in 36.5%. 3. Intellectual disturbances were observed in 68.6% of the patients, including impression disturbance in 58.3%, memory disturbance in 51.9%, calculation disturbance in 63.5%, thinking disturbance in 61.5% and disorientation in 14.1%. 4. Apathy and disorder of volition and interest which were found in 72.4% were included in personality change because all symptoms persisted for many years. Personality change was classified as follows: weakness of emotion and will (hypobulia) in 54.4%, infantilism in 35.2%, hyperactive, talkactive and lack of inhibition in 18.5%, lack of self-possession and unstable temper in 9.6%, depression in 15.3%, neurosis in 7.6% and schizophrenic state in 2.5%. Among these symptoms of personality change, weakness of emotion and will and infantilism were conspicuous among the patients who remained in a coma for more than 6 hours soon after the accident but showed no relationship with age. 5. Neurological symptoms that were found in 48.7% of the patients were classified as sensory disturbance in 25.6%, peripheral nerve symptoms in 16.0%, pyramidal symptoms in 14.1%, ataxia and cranial nerve symptoms in 7.1%, paroxysmal symptoms in 6.4% and focal symptoms in 4.5%, extrapyramidal symptoms in 21.8% (Parkinsonism in 4.5%, tremor in 10.9% and muscle rigidity in 16.0%) and vegetative symptoms in 37.2%. 6. At the time of investigation, 5 CO poisoning patients were classified as serious cases (3.2%), 20 as comparatively serious (12.8%) medium-degree cases, 28 as comparatively mild (17.9%) medium-degree cases, 37 as comparatively serious (23.7%) mild cases, 42 as comparatively mild (26.9%) mild cases, 24 (15.4%) as having symptoms which were not problematic, and 24 (15.4%) as having symptoms that markedly worsened due to complication. 7. A total of 138 (88.4%) cases had complications were classified as follows: 78 cases (50.0%) of hypertension, 62 cases (39.7%) of cerebral infarction, 24 cases (15.4%) of cardiac disturbance, 21 cases (13.5%) of diabetes mellitus, 14 cases (9.0%) of hepatic disturbance and six cases of silicosis (3.8%). 8. Cranial MRI was carried out for 129 cases (82.7%). Of the abnormal findings identified, cerebral atrophy accounted for 72.0% (93 cases), including moderate and severe cases in 47.2% (61 cases), pallidum lesion for 37.9% (49 cases), lacunar infarction (including cerebral infarction) for 52.7% (68 cases), and hippocampal atrophy for 18.6% (24 cases). Many cases of cerebral atrophy and hippocampal atrophy were observed in patients who remained in the initial coma for more than 12 hours and were 80 years of age or old. The cases of pallidum lesion were observed in patients who remained in the initial coma for more than 6 hours, and no relationship with age was found. The other findings, cerebral atrophy and lacunar infarction showed a slight relationship with age. 9. Among the moderate and serious cases of intellectual disturbance, cerebral atrophy constituted to 62.5%, lacunar infarction 68.7% and pallidum lesion 50.0%. Among the moderate and serious cases of personality change, cerebral atrophy constituted 78.5%, lacunar infarction 35.0% and pallidum lesion 50.0%. Moreover, among extrapyramidal symptoms, pallidum lesion constituted 58.6%, cerebral atrophy 55.1% and lacun

This is a review on current knowledge of chronic occupational mercurialism syndrome. Major scientific studies and reviews on clinical manifestation and physiopathology of mercury poisoning were evaluated. The search was complemented using Medline and Lilacs data. Erethism or neuropsychological syndrome, characterized by irritability, personality change, loss of self-confidence, depression, delirium, insomnia, apathy, loss of memory, headaches, general pain, and tremors, is seen after exposure to metallic mercury. Hypertension, renal disturbances, allergies and immunological conditions are also common. Mercury is found in many different work processes: industries, gold mining, and dentistry. As prevention measures are not often adopted there is an increasing risk of mercury poisoning. The disease has been under diagnosed even though 16 clinical forms of mercury poisoning are described by Brazilian regulations. Clinical diagnosis is important, especially because abnormalities in the central nervous, renal and immunological systems can be detected using current medical technology, helping to develop the knowledge and control measures for mercurialism.
