Researchers of the QIMR Berghofer Medical Research Institute in Brisbane have discovered potential causes behind the pitfalls in the major drugs used to aid in treating Parkinson's disease.
The issues behind the medications used to treat Parkinson's stemmed from the fact that they increased dopamine levels in the brain causing patients to inherit the risk of developing compulsive disorders.
Dr Phil Mosley stated that for those who are on the medication, the degenerating dopamine cells in the brain are replaced, which could potentially imbalance other areas of the brain.
The effect of this could result in addictive behaviours in patients with damaged brain cells in regions of the brain associated with decision making and impulse control.
