A new study analyzing the psychological aspects of Parkinson's disease analyzes a number of the same issues about Parkinson's disease that we've written about before ( ). However the authors, writing in the Journal of Neurology, Neurosurgery, and Psychiatry were bold enough to propose some subtypes or clusters of Parkinson's related psychoses. They group different patients into the clusters:
- Mild
- Mood
- Apathy
- Aggitation
- Psychosis
These researches hope to further develop these subtypes within Parkinson's, and see if there are treatments that specificly help each of these clusters.
