Low doses of ecstasy associated with decline in verbal memory

---

Omschrijving
Even low doses of Ecstasy may be associated with a decline in language-related memory, according to a report in the June issue of Archives of General Psychiatry, one of the JAMA/Archives journals. Ecstasy is an illicit recreational drug popular among young people, according to background information in the article. Research in both humans and animals suggests that the drug can harm the brain. Ecstasy may damage nerve cells that respond to the hormone serotonin, which is involved in mood, thinking, learning and memory. Thelma Schilt, M.Sc., of the Academic Medical Center of the University of Amsterdam, the Netherlands, and colleagues recruited 188 volunteers (average age 22) who had not used Ecstasy but reported that they were likely to try it soon. Within three years of the initial evaluations, which took place between April 2002 and April 2004, 58 individuals began using Ecstasy. They were compared with 60 individuals who had the same age, sex and intelligence score but who did not use Ecstasy during the follow-up period. All participants took tests that assessed various types of memory—including attention, verbal memory for words and language, and visual memory for images—at the beginning and end of the study. Verbal memory was tested by memorizing a series of 15 words and repeating them immediately and again 20 minutes later.
