title: Learning and memory impairment with benzhexol.
abstract: A double-blind trial to determine the effects of a single dose of 2 mg benzhexol on cognitive functioning was undertaken using normal volunteers. Ninety minutes after the drug or placebo was taken, subjects completed a battery of psychological tests designed to measure learning, memory and motor skills. Benzhexol ingestion was associated with significant impairment of short-term memory and slowing of the rate of new learning.
