Thanks for writing in. Parkinson
disease has symptoms like rigidity, tremors and bradykinesis means slowness of movement - you may be aware of this. In the later stages it may lead to dementia
and neuropsychiatric problem like apathy, depression
, etc. However there no such direct relationship between decreased blood supply to organs and parkinsonism. Fainting
episodes may be related to pace maker activity. It may also a part of neuropsychiatric stage of disease where it may be called as a fainting episode.
It will be better to consult the physician again and collect proper information. Because there is remote chance that course of disease has been complicated by septicaemia
Hope I have answered your query. If any further concern, please let me know.
