My mother is 86 and was diagnosed with Parkinson's disease about 17 years ago. She has limited mobility, but gets around fairly well with a rollator and can walk limited distances. She eats and drinks well on her own, but requires help in all other areas of daily living. About 4 years ago, she started having episodes of being non responsive. During these episodes she would not respond to us touching her hands or feet, and her eyes remained closed until they were over. Her blood pressure was normal and she has never had issues with high or low glucose. They last anywhere from a few minutes, with the longest one being 2 hours. Her neurologist recommended a brain scan to determine if she was having seizures or mini strokes, but the results were negative. Blood work is always good, and they diagnosed these episodes as being "behavioral". We cannot figure out what causes them, and can't understand why the doctor attributed them to behavior or "acting out." Generally, her routine remains the same and we cannot put our figure on anything that upsets her prior to the episodes taking place. Recently, these non responsive episodes occur almost weekly or at least a few times a month. It usually happens in the morning but on occasion they have occurred in the afternoon as well. Has anyone experienced this with a loved one or someone they know who has Parkinson's? Is this attributed to the progression of Parkinson's disease and should I seek a second opinion from another doctor.
