Scientists discover what creates an obsessive compulsive disorder
SCIENTISTS CLAIM TO have discovered what creates an obsessive-compulsive disorder.
It has always been suspected that the condition, which affects two to three per cent of the population and sees individuals locked into a pattern of recurring behaviour – washing one’s hands, for instance – was down to a type of gene, however, now scientists believe it could be caused by missing brain cells.
‘Impaired brain function in the areas of the brain associated with stopping motor responses may contribute to the compulsive and repetitive behaviours that are characteristic of OCD,’ explains Lara Menzies, the lead author of a new paper on the subject, which has been published in Brain magazine.
‘These brain changes appear to run in families and may represent a genetic risk factor for developing the condition. The current diagnosis of OCD is subjective and therefore knowledge of the underlying causes may lead to better diagnosis and ultimately improved treatments.’
