Specific effects of cyclandelate on memory

In an uncontrolled clinical trial of 6 weeks' duration conducted in 20 male patients, aged 49 to 68 years, with memory disorders, cyclandelate 1200 to 1600 mg daily was found to be effective in improving memory as reflected by psychiatric, psychometric and psychophysiological measurements. Treatment with cyclandelate produced clinical effects which were selective for the Wechsler Memory Scale items of visual reproduction and orientation--indicators of the declarative memory. Moreover, the improvements seen in the average auditory reaction and critical flicker fusion frequency demonstrates its effect on procedural memory. Thus, our results indicate that this drug may be therapeutically useful in memory disorders of various aetiology, and that further exploration of the place of cyclandelate in this clinical area is needed.
