Pharmacological study in Meige's syndrome with predominant blepharospasm.

Objective quantification of the symptoms of Meige's syndrome is difficult and has not been performed in the majority of pharmacological studies of Meige's syndrome published so far. The aim of the present study was to reexamine the therapeutic potential of biperiden, clonazepam, haloperidol, and lisuride using an objective method of quantification of the symptoms. Eleven patients received daily i.v. injections of biperiden, 5.0 mg; clonazepam, 1.0 mg; haloperidol, 2.5 mg; lisuride, 0.05 mg; and placebo in randomized order. The symptoms of the patients [idiopathic blepharospasm (IB), in 11 patients, oromandibular dystonia (OMD) in four patients] were quantified by a blind observer counting the frequencies and recording the cumulative duration of sustained spasms of IB and OMD over periods of 4 min before, and 15, 30, 60, 90, and 120 min after the i.v. challenges. Baseline quantification of IB and OMD was performed at identical intervals on randomized days of the trial. Significant improvement of the IB scores was found in response to biperiden and clonazepam and a trend toward improvement in response to lisuride (Wilcoxon test). Evaluation of the individual IB scores of each patient following the various drug challenges failed to predict the therapeutic potential of these drugs for subsequent oral treatment.

Visuoperception and visuospatial and visuorotational performance in Parkinson's disease.

Forty patients with Parkinson's disease were compared with 33 normal controls with respect to their performance in the Wechsler Adult Intelligence Scale subtests "information", "similarities", "block design", and "picture completion", in a test for visual neglect (Hamsher's line cancellation test) and in tests for visuospatial and visuorotational abilities (cube task from Amthauer's intelligence structure test and Rybakoff figure test, as revised by Meili). The findings show that the patients scored significantly worse than the controls (Mann-Whitney U test, P = 0.004) in the Rybakoff figure test, testing visual concept finding, imagination and visual rotation. In the other tests no significant differences were found between the patients and the controls. The deficit of the patients in the figure test of Rybakoff correlated significantly with tremor (P = 0.013), akinesia (P = 0.009), disability (P = 0.043), and age (P = 0.004, Spearman rank correlation).

Experience with selegiline in the treatment of Parkinson's disease.

28 patients with Parkinson's disease and long-term levodopa therapy have received additional selegiline (10 mg/d) over the past 3 years and been followed up for a mean period of 18.8 months. Two thirds improved with a reduction of global disability and amelioration of end-of-dose effects, nocturnal and early-morning akinesia. Peak-dose dyskinesias tended to increase with selegiline while biphase and off-period involuntary movements improved in some cases. Patients already on maximally tolerated doses of levodopa and those with severe on-off swings did not gain significant benefit. 8 of 18 responders lost their initial response within 1.5 years.

Therapeutic experiences with an abeorphine derivative in Parkinson's disease.

Marked improvement of the clinical state owing to CI 201-678 treatment was seen in six patients; no definite improvement was achieved in three patients. Daily fluctuations were improved in two patients. CI 201-678 demonstrated a good effect against rigidity, impairment of gait and posture, as well as impaired self-care, although daily levodopa dosage was concomitantly reduced. In two patients, CI 201-678 was discontinued because of side-effects, while one patient stopped treatment for reasons not related to the drug. In contrast to apomorphine and other dopamimetic substances, the emetic side-effect of CI 201-678 is minimal (nausea in one patient). no arterial hypotension was not seen. It has to be mentioned that the two drug-related drop-outs were receiving CI 201-678 in a rapidly increasing dosage. It is likely that the side-effects would have been less pronounced if the dosage had been more slowly increased. However, the preliminary results indicate that CI 201-678 is a promising substance for the treatment of patients with predominant rigid-akinetic symptomatology, in combination with levodopa therapy or in the place of levodopa.

[Clinical subtypes of Parkinson disease].

Clinical findings in 196 patients with Parkinson's disease are reviewed and a subdivision of cases into an "equivalent" type (ART-type), akineto-rigid type (AR-type) and tremordominant type (T-type) of Parkinson's disease is introduced. Differences in the rate of progression and association with mental changes as well as in the predisposition for developing L-dopa induced dyskinesias have been observed between these subtypes of Parkinson's disease. The possible relation between tremordominant Parkinson's disease and essential tremor is also discussed.

Prognostic implications of the motor symptoms of Parkinson's disease with respect to clinical, computertomographic and psychometric parameters.

Forty-four Parkinson patients (19 patients of the rigid-akinetic type, 13, of the rigid-akinetic-tremor type, and 12, of the tremor type) were included in a study in order to analyse correlations of the expression of the motor symptoms tremor, rigidity, akinesia, with other clinical parameters, computertomographic aspect of brain atrophy and psychometrically assessed cognitive parameters. Rigidity and akinesia are significantly positively correlated with the severity of motor dysability, stage of the disease, and brain atrophy, as is akinesia with a history of pharmacotoxic psychosis. Tremor is significantly negatively correlated with motor dysability, stage of the disease, and history of pharmacotoxic psychosis. Akinesia is correlated with visuomotor dysfunction (tested with Bender Gestalt Test) and rigidity with the depression score (Zung scale). The tremor type is favorable, the rigid-akinetic type unfavorable with respect to motor disability and psychosis.

Magnetic resonance imaging in the diagnosis of spinal cord diseases.

Experience with magnetic resonance imaging in 22 patients with diseases of the spinal cord is reported. Important additional diagnostic information as compared to conventional neuroradiological techniques (myelography, spinal CT) was gained especially in cases of hydrosyringomyelia, intraspinal tumour and multiple sclerosis. It is suggested that magnetic resonance imaging may become the method of choice in the diagnosis of structural spinal cord diseases.

The rigid spine syndrome--a myopathy of uncertain nosological position.

Four patients meeting the clinical criteria of the rigid spine syndrome are presented; they are one girl with a positive family history and three boys. Clinical and histological findings are discussed in relation to the 14 cases of rigid spine syndrome reported in the literature. The delineations of the syndrome from other benign myopathies with early contractures are discussed suggesting that the rigid spine syndrome probably does not represent a single nosological entity.

Klüver-Bucy syndrome in man: experiences with posttraumatic cases.

After the original description of characteristic behavioral changes in rhesus monkeys after bilateral resection of major portions of the temporal lobes by Klüver and Bucy in 1937 [11], similar syndromes have repeatedly been reported in human pathology. The present paper is based on clinical analysis of 40 cases of traumatic apallic syndrome (TAS), 30 of whom developed a complete or partial Klüver-Bucy syndrome during recovery. The dynamics in the development of a Klüver-Bucy syndrome during remission of a TAS are analyzed. The delineation between a pre-stage, full-stage and remission-stage of the Klüver-Bucy syndrome is suggested.
