Abstract
Methamphetamine use has spread in many European countries and the United States. The
current review provides a summary and critical analysis of research on cognitive deficits
associated with methamphetamine, also known as “crystal meth.” The literature search
performed for this review led us to the hypothesis that methamphetamine use is associated
with persistent changes in brain metabolism that result in various impairments, such
as deficits in memory, attention, and concentration. The dopaminergic system in particular
seems to be affected. Some studies indicate that cognitive impairments may improve
when users become abstinent, but results of other studies are conflicting. This review
discusses these findings and the consequences for the development of a specific addiction
treatment for methamphetamine.
