Comparative Study Clinical Trial
Treatment of ataxia in cortical cerebellar atrophy with the GABAergic drug gabapentin. A preliminary study.
The aim of this work was to investigate the efficacy of the GABAergic drug gabapentin in the treatment of the cerebellar signs caused by cortical cerebellar atrophy (CCA). Ten patients with CCA received gabapentin in single doses of 400 mg in an open-label study; thereafter, daily administration of 900-1,600 mg of gabapentin was continued during at least 4 weeks. An ataxia scale based on clinical findings was used to evaluate the cerebellar signs at baseline and after administration of the drug. ⋯ An important clinical amelioration was also evident. Gabapentin has been demonstrated to be capable of improving the cerebellar signs in cases of CCA, after single doses and after continued administration of the drug during 4 weeks. GABAergic enhancement or supplementation could play an important role in the treatment of diseases of the cerebellar cortex associated with a deficit of GABA.

Comparative Study
Predictors of outcome in patients with normal-pressure hydrocephalus.
Despite emerging knowledge of over 40 years, the postoperative results after shunt implantations in patients diagnosed for normal-pressure hydrocephalus (NPH) have not improved significantly in the last decade. For this reason, predictors have to be identified in order to preoperatively predict the course of disease. From 1982 to 2000, we examined in a prospective study 200 patients diagnosed for NPH. ⋯ In 80 patients with an early stage NPH (without cerebral atrophy) and a short course of disease (<1 year), slightly distinct dementia and an implanted Miethke Dual-Switch valve were significant predictors for a positive postoperative outcome. The outflow resistance measured in the intrathecal infusion test showed only a minimal relevance for the outcome. Those 75 patients with a late state NPH (with cerebral atrophy) had a better outcome when dementia was not present, the outflow resistance was >20 mm Hg.min/ml, the CSF tap test was positive and a Miethke Dual-Switch valve was implanted.
