Doctors Discovered How The Brain Dies – Part 1 of 3
Doctors Discovered How The Brain Dies. Shrunken structures prearranged the brains of heavy marijuana users might explain the stereotype of the “pothead,” brain researchers report. Northwestern University scientists studying teens who were marijuana smokers or earlier smokers found that parts of the brain related to working memory appeared diminished in size – changes that coincided with the teens’ awful performance on memory tasks. “We observed that the shapes of brain structures related to short-term memory seemed to collapse inward or shrink in people who had a history of constantly marijuana use when compared to healthy participants,” said study author Matthew Smith.
He is an assistant research professor in psychiatry and behavioral sciences at the Northwestern University Feinberg School of Medicine, in Chicago. The shrinking of these structures appeared to be more advanced in proletariat who had started using marijuana at a younger age. This suggests that youngsters might be more susceptible to drug-related memory loss, according to the study, which was published in the Dec 16. 2013 version of the journal Schizophrenia Bulletin.
So “The brain abnormalities we’re observing are directly related to poor short-term memory performance. The more that genius looks abnormal, the poorer they’re doing on memory tests”. The paper is provocative because the participants had not been using marijuana for a couple years, indicating that memory problems might persist even if the person quits smoking the drug, said Dr Frances Levin, chairman of the American Psychiatric Association’s Council on Addiction Psychiatry. At the same time, Levin cautioned that the manuscript presents a chicken-or-egg problem.
