[Psychological aspects of neurotransplantation]

The psychological situation of Parkinson patients and the functions and roles of others involved--doctors, donors, caregivers--are discussed with reference to ethically based decisions about neurotransplantation. Psychological stressors and changes of psychological functions in Parkinson's disease are described. Possible psychological risks due to short and long term changes, especially changes in emotionality, are discussed. Proposals are made for pre- and post-transplantation care involving broad neuropsychological follow up testing and psychological counseling, particularly to deal with unfulfilled expectations.
