The research team, as part of their study, drew comparisons between 106 Parkinson's patients and 106 healthy people, belonging to the same age and sex. The groups' responded to questions that sought to throw light on their personality traits and behavior also including preferences on beverage and habits.
The findings of the study revealed that patients with Parkinson's had low scores in risk taking behavior parameter and in those associated with sensation and feelings. Anxiety and depression had very many high scorers amongst the Parkinson group.
The data was dissected, researchers read between the lines to reveal that there is a very clear link between sensation seeking/risk taking behavior and higher rates of Parkinson's disease, notwithstanding smoking, coffee and alcohol intake.
The findings have encouraged the authors to opine that there may be a neurobiological link that is causing the low sensation behavior, typical of the Parkinson character.
