Recreational cocaine use may impair inhibitory control

In a study published Nov. 7 in the online, open-access journal PLoS ONE, researchers at Leiden University and the University of Amsterdam, led by Lorenza Colzato, employed the 'stop-signal paradigm' to measure the length of time taken by subjects to initiate and suppress a prepared reaction. The results show that while both recreational users of cocaine and non-users performed similarly in terms of response initiation, users needed significantly more time to inhibit their responses.

   Impulsivity is a problem common to many different personality and psychiatric disorders, including alcoholism. A new study that looked at impulsivity among alcoholic subpopulations has found that, one, the inability to delay gratification may be a vulnerability marker for alcoholism, and two, certain inhibitory-control issues may be specific to antisocial and borderline personality disorders.

   Consistent alcohol consumption can impair immunity functions following surgery. A new rodent study has found that chronic drinking can result in a severe form of pneumonia following surgery. Study authors recommend that patients considering surgery control their drinking habits, and also be very honest with their doctors about their drinking habits, prior to surgery.

   07-10-2007 · EurekAlert!
   Researchers from Boston University School of Medicine have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadian hormone melatonin, can attenuate the prenatal effects of cocaine. These findings appear in the July 11 issue of the journal PLoS ONE.
