One study suggests that the finding may shed light on the physiology of paranoia in general.
U.S. researchers. UU. have identified genetic variants that increase the risk of paranoia in cocaine addicts.
In their study of almost 4,000 people of African and European ancestry, the team of Yale University and the Faculty of Medicine at Boston University examined an area of the genome had previously been shown that it was linked to cocaine dependence and the paranoia induced by this drug.
The researchers conducted a genetic analysis of eleven variants of the gene-endomanosidasa (NSAIDs), which metabolize complex carbohydrates. They found that nine of the variants were related to cocaine-induced paranoia among African Americans and six variants were identified among those of European origin.
Variants were also associated in this area of the genome with cocaine dependence. (more…)
There are various definitions of addiction.
