An unusual case with relapsing neuromyelitis optica associated with undifferentiated connective tissue disease.

A case is presented with attacks of optic neuritis followed by severe myelitis 15 years later, in coincidence with a severe stressful life event. This female patient was also affected by undifferentiated connective tissue disease. This case presents some unusual and atypical findings such as: the association of a relapsing neuromyelitis optica with an undifferentiated connective tissue disease, a very long interval between optic neuritis and myelitis, and the important role of a stressful event in developing a relapse.

Olfactory sensitivity in early-stage Parkinson patients affected by more marked unilateral disorder.

Two groups of subjects, 6 medicated Parkinson patients at an early stage of disease and affected by more marked right unilateral disorder and 12 normal elderly people, were examined on matching and naming olfactory tasks. On the former, subjects had to recognize among four previously sniffed odours, while on the latter they had to label an odour by choosing among four alternatives proposed by the examiner. Stimuli were administered to both nostrils. Analysis indicated that Parkinson patients were less efficient with the left nostril in the matching task, supporting the hypothesis of a larger compromise in the nostril contralateral to the side of the body more affected by the disease. Such a difference was not observed for the elderly people. Data are discussed with reference to the loss of dopamine in Parkinson patients.

Chorea in patients with AIDS.

OBJECTIVE: To describe differing etiologies and possible anatomoclinical correlates of choreic movements in a series of AIDS patients. METHODS: We analyzed the clinical records and neuroimaging data of 5 consecutive AIDS patients who developed choreic movements at our center from January, 1994 to December, 1996. RESULTS: There were 2 cases of focal choreic dyskinesias, 1 of right hemichorea, and 2 of generalized chorea. Onset was acute and febrile in 1 case, and subacute in the other 4. In 1 patient the chorea was the AIDS onset symptom; in another choreic movements were the first neurological symptom following AIDS diagnosis; in 2 patients AIDS had a neurological onset other than chorea; and in the fifth patient buccofacial dyskinesias appeared following the development of bacterial encephalitis. CONCLUSION: Chorea was associated with cerebral toxoplasmosis in 2 patients, progressive multifocal leukoencephalopathy in 1, subacute HIV encephalopathy in another, and was probably iatrogenic in the last. Chorea is not unusual in AIDS, however the causes are variable and careful neuroradiological and clinical evaluation is required to identify them. AIDS-related disease should be considered in young patients presenting with chorea without a family history of movement disorders.

Sporadic choreas: analysis of a general hospital series.

The incidence of sporadic chorea among general hospital admissions is unknown, and the relation of clinical manifestations and etiological factors to neuroimaging findings has been little investigated in this condition. We reviewed the 7,829 cases admitted to the neurology departments of two general hospitals over 3.25 years and identified 23 (8 male and 15 female) cases of apparently sporadic chorea. Analysis of the records of these patients permitted etiological classification as follows: drug-induced chorea (5 patients), vascular chorea (6 patients), chorea-vasculitis (1 patient), Sydenham's chorea (1 patient), AIDS-related chorea (5 patients) and in 4 patients neither etiological factors nor neuroradiological alterations were found. Finally in 1 patient, the genetic test for Huntington's disease was positive. Thirteen patients had pathological neuroimaging findings; however, in only 3 were basal ganglia lesions considered to be the cause of the chorea. We conclude that sporadic chorea is not rare among neurological department admissions (we found 2.94 cases per 1,000 admissions) and only in a minority of cases is the symptomatology attributable to gross basal ganglia lesions; HIV infection is an emerging cause of chorea.

Chorea as a symptom of neuroborreliosis: a case study.

Borrelia burgdorferi (Bb) can cause a large number of neurological symptoms. Although extrapyramidal disturbances are rare (representing less than 2% of all neurological complications), diffuse choreic dyskinesias have been described during the course of mild encephalitis. The data published in the literature suggest that there are clinical and neurological analogies between neuroborreliosis and multiple sclerosis (MS). The presence of specific anti-Bb antibodies in cerebrospinal fluid is a discriminating factor that allows a diagnosis of neuroborreliosis to be made. We describe the case of a patient with Lyme disease, characterised by widespread chorea and behavioural disturbances. Emphasis is placed on the atypical onset and evolution, the difficulties encountered in formulating a diagnosis, and the uncertainties concerning the pathophysiology and clinical/neuroradiological correlations of the disease.

Early-onset Parkinson's disease.

The study was conducted on 120 patients (76 men and 44 women) affected by idiopathic Parkinson's disease (IPD) responsive to L-dopa and observed for many years. Sixty had clinical onset between the ages of 20-40, representing 10.2% of our PD population; in the others the symptoms began after the 40th birthday. The two groups were matched for sex and length of illness. In all patients a diagnosis of IPD depended on history and clinical and neuroradiological findings. Clinical, pharmacological, evolutive, and epidemiological data were collected on all patients. Thirty-six patients from each group performed motor dexterity tests (reaction time to expected and unexpected stimuli) and cognitive tests (Wechsler Adult Intelligence Scale. Benton, Short tale, and Zazzo's speed and accuracy test). To assess the prevalence of dementia and the severity of psychiatric side effects of L-dopa administration, the 60 patients with early-onset PD were compared with 134 consecutive unselected PD patients. Five percent of early-onset PD patients had a family history of the disorder. Our study showed that early-onset PD does not differ fundamentally from the late-onset form except that the former is characterized by a more rapid establishment of the full-blown parkinsonian clinical picture and deterioration of the therapeutic efficacy of L-dopa, with an earlier appearance of side effects. The results of our neuropsychological investigations suggest that early-onset PD may be a "pure" form of extrapyramidal compromise with exclusively motor manifestations.

Terguride in the treatment of Parkinson disease: preliminary experience.

Terguride, a partial DA-agonist with both dopaminergic and antidopaminergic properties, was tested in 11 PD patients in the "decompensated" phase of the disease, characterized by the presence of dyskinesias and motor fluctuations. Combined treatment of these patients with 1 mg/day of terguride and stabilized doses of levodopa reduced the severity and frequency of dyskinesias and motor fluctuations along with a slight but significant improvement of parkinsonian clinical picture. The "modulatory" effect of terguride on DA receptors, in this experimental conditions, is discussed.

Mortality associated with early and late levodopa therapy initiation in Parkinson's disease.

We evaluated the possible influence of early levodopa treatment on the mortality of Parkinson's disease (PD). One hundred forty-five consecutive parkinsonian patients initiated treatment with levodopa between 1970 and 1983. Ninety-eight of those started levodopa therapy 2 or more years after symptom onset, while 47 received levodopa within the 1st 2 years of the disease. At the end of follow-up, in December 1985, 49 patients had died. Mortality was 2.5 times higher among patients who delayed initiation of levodopa therapy 2 or more years than among those who initiated the therapy earlier. Age and disease severity were the most significant predictors of survival after initiation of levodopa treatment. The risk of death was 10% higher every year of age increase and was 2 and 4 times higher, respectively, for patients at Hoehn and Yahr stages II and III than for patients at Hoehn and Yahr stage I. When we controlled for the effect of age and disease severity on mortality, the cumulative death probability was no longer significantly higher among patients who delayed levodopa treatment than among patients treated within 2 years from disease onset. As far as mortality is concerned, the results show that the time of levodopa treatment initiation during PD has no influence and the drug can be introduced as soon as indicated by the severity of the disease progression.

Lisuride in Parkinson's disease. 4-year follow-up.

Lisuride at a mean daily dose of 3 mg was given to 48 patients with idiopathic Parkinson's disease. Twenty received lisuride alone (Group A) and 36 received lisuride + L-Dopa + peripheral decarboxylase inhibitors (Group B). Dropouts were due primarily to lack of efficacy in Group A patients and to mental side effects in Group B patients. The patients who remained in the study for the full 4 years showed distinct improvement, which was maintained. Group A patients did not have the on-off phenomenon or abnormal involuntary movements.

Lisuride in de novo parkinsonian patients: a four-year follow-up.

Lisuride at a mean daily dose of 3.2 mg was given to 15 untreated idiopathic Parkinson's disease patients. There were 10 dropouts, due mainly to inefficacy in the first months of therapy. The parkinsonian pattern in the patients who remained in the study for the full 4 years showed distinct improvement, which was maintained for less than 2 years. The patients did not develop "on-off" phenomena or abnormal involuntary movements during follow-up.

Dementia and cognitive impairment in Parkinson's disease.

The frequency of dementia, the clinical characteristics and the pattern of cognitive impairment were studied in 147 unselected Parkinsonian patients. Twenty-one patients (14.28%) were judged to be demented. They had a more severe and widespread cognitive deficit although they were affected particularly in those tests that already discriminated Parkinsonian patients from controls. A direct comparison of Parkinsonian dementia with other types of dementia is needed to validate the concept of subcortical dementia.

Pharmacological approaches to Parkinson's disease in the different phases of evolution.

The pharmacological approaches to Parkinson's disease in the different phases of evolution (initial or slight, complete and complicated) are discussed. The modality of confronting the therapeutic approach according to the different evolutive phases makes it possible to personalize the therapy, in an attempt to obtain the optimal clinical effect with minimum side effects. Various drugs available and future perspectives are considered.

(-)Deprenyl in Parkinson's disease: a two-year study in the different evolutive stages.

Seventy-nine patients with idiopathic Parkinson's disease in various phases of evolution of the clinical picture were studied. All the patients, already under treatment with L-dopa + PDI, were treated with (-)deprenyl at the dose of 10 mg/day orally in two daily administrations. The mean follow-up was 8.7 months (range, 1-29). Overall, 47.6% of the patients improved, 27.4% showed a marked improvement, 38.1% showed evident modifications, and 27.4% worsened. Sixteen patients were excluded from the study for various reasons. In 53.2% of the cases it was possible to reduce the daily L-dopa dose by a mean of 30%. Overall, (-)deprenyl was effective in the treatment of our parkinsonian patients in the various conditions evaluated, and thus constitutes a new therapeutic strategy for Parkinson's disease.

Deprenyl in Parkinson disease: personal experience.

The aim of this study was to evaluate the therapeutic activity of Deprenyl in patients with Parkinson disease already being treated with L-Dopa + PDI. 15 selected patients were allocated to two groups according to clinical features and course of the disease, the first consisting of 9 patients with a mean disease duration of 5 years without any side-effects attributable to L-Dopa and the second of 6 patients with long-term illness (a mean disease duration of 8 years), side-effects and "on-off" phenomenon. All the patients of the first group completed the scheduled 10-week course of Deprenyl treatment obtaining a significant improvement on the baseline WRS scores, in tremor, in rigidity, in motility and a 30.5% reduction in the L-Dopa dose. The patients of the second group showed no significant modification of the symptoms; in 2 cases the treatment was discontinued due to acute delusional-hallucinatory disorders and deterioration of the involuntary movements. A more precise evaluation of Deprenyl activity in the L-Dopa syndrome will depend on further studies.
