Abstract
In a first double-blind, placebo-controlled parallel experiment, 20 volunteers with a median age of 45 years were treated for 1 week with either sabeluzole (R 58735) or placebo. Before and after the treatment period, they were subjected to a Selective Reminding Procedure in which a 20-word list had to be learned. No differences between the two groups were seen for total recall, short-term retrieval, total long-term retrieval, random long-term retrieval and long-term storage. However, a significant improvement in consistent long-term retrieval (cLTR) was seen for the subjects treated with sabeluzole. This effect was restricted to the group of the poor performers, i.e. those with a baseline cLTR of 50% or less. In a second experiment, 12 healthy elderly volunteers with a median age of 59 years were subjected to the same test procedure. They were treated with sabeluzole in a single-blind fashion. Again the cLTR improved significantly in the group of poor performers. It was thus confirmed that sabeluzole ameliorates retrieval functions and primarily so in poor performers.
