Unlike younger recreational gamblers who show high rates of alcohol use and abuse, depression, bankruptcy and incarceration, there appears to be an association between recreational gambling and good health among elderly persons, according to a Yale study in the American Journal of Psychiatry. Rani Desai, associate professor of psychiatry at Yale School of Medicine, said it is not clear why there is a positive correlation of good health in moderate gamblers 65 years and older. It may be, she suggested, that healthier adults who are able to gamble are simply healthier to begin with. There may be other reasons as well, Desai said.
The principal active ingredient in marijuana causes transient schizophrenia-like symptoms ranging from suspiciousness and delusions to impairments in memory and attention, according to a Yale research study. Lead author D. Cyril D'Souza, M.D., associate professor of psychiatry at Yale School of Medicine, said the study was an attempt to clarify a long known association between cannabis and psychosis in the hopes of finding another clue about the pathophysiology of schizophrenia.
The ability to recognize persons encountered during highly threatening and stressful events is poor in the majority of individuals, according to a Yale researcher.
''Contrary to the popular conception that most people would never forget the face of a clearly seen individual who had physically confronted them and threatened them for more than 30 minutes, a large number of subjects in this study were unable to correctly identify their perpetrator,'' said Charles Morgan III, M.D., associate professor of psychiatry at Yale School of Medicine.
Researchers have discovered a gene mutation that causes a condition apparently identical to Huntington's Disease, helping explain why some people with the disorder do not have a separate mutation found in most cases. The finding may help reveal why some diseases, like Huntington's, Alzheimer's and Parkinson's, destroy some brain cells while sparing others. "For all practical purposes this is Huntington's Disease, yet it's caused by a different mutation on a completely different chromosome," said Russell L. Margolis, M.D., associate professor of Psychiatry at Hopkins and director of the Johns Hopkins Laboratory of Genetic Neurobiology. "This is a rare version of an already rare disorder, but the mutation that causes it may not only help us better understand Huntington's Disease, but could boost our understanding of many other neurodegenerative disorders."
A new study aims to determine once and for all whether a link exists between obsessive-compulsive behavior and strep infections in children. The research, to be conducted by the University of Florida and the National Institutes of Mental Health, is prompted by anecdotal reports from parents with OCD kids that their children's behavior, such as compulsive hand washing, worsens when the child is ill with strep.
