A placebo-controlled, randomized double-blind study conducted at a general practitioner's surgery was designed to investigate the efficacy of bencyclane in 120 outpatients with cerebral dysfunctions based on organic brain syndrome. The study started with a 4-week placebo washout phase and then continued with a 12-week treatment phase. 200 mg Bencyclane-hydrogenfumarate was administered b.i.d. Efficacy was assessed by a doctor's symptom rating (SCAG) and a study nurse's rating (BGP) as well as by two performance tests (CFF and ZVT-G). Data from 106 patients (52 under bencyclane and 54 under placebo) were statistically analysed. More side effects were seen under bencyclane than under placebo, in particular insomnia, headache, akathisia, nausea and vomiting. As an a priori hypothesis, it was stated that after alpha-adjustment there should be a statistically significant difference in symptomatology (SCAG, BGP) and performance (CFF, ZVT-G). With regard to performance, the zero hypothesis could be rejected on the 5% level, and on the 1% level with respect to symptomatology. The experimental error on both the performance and the symptom level was below 6%. The drug effects were significant on a confirmatory level and are considered to be also of clinical relevance.
