The changes in activity of excitatory and inhibitory neurotransmitter systems is similar to that which occurs in individuals suffering from limbic or temporal lobe epilepsy .
A link between these types of drugs and cognitive impairment isn't a totally new discovery, but for the first time, researchers used brain imaging techniques to determine the physical changes ...
