Could this be why liars bother me so much? Ray PARKINSON'S DISEASE NEWS from Viartis 7th April 2009 - New research PARKINSON'S DISEASE PATIENTS HAVE TROUBLE LYING Brain [2009] Mar 31 [Epub ahead of print] (Abe N, Fujii T, Hirayama K, Takeda A, Hosokai Y, Ishioka T, Nishio Y, Suzuki K, Itoyama Y, Takahashi S, Fukuda H, Mori E.) Complete abstract The medical literature has suggested that people with Parkinson's Disease have characteristic personality traits such as industriousness, seriousness and inflexibility. They have also been described as "honest", indicating that they have a tendency not to deceive others. These personality traits may be associated with dysfunction of specific brain regions affected by Parkinson's Disease. In the present study, researchers showed that most people with Parkinson's disease are "honest", and that this personality trait might be derived from dysfunction of the prefrontal cortex. People with Parkinson's disease had difficulty making deceptive responses when compared to healthy controls. This difficulty was significantly correlated with reduced function in part of the brain. The results are the first to demonstrate the greater honesty found in people with Parkinson's Disease and that it has a neurobiological basis.
