Exercise, intermittent fasting, tai chi, and use your "bad"side as much as possible. Says a top UK neurologist.
I was back in the UK last week because my Dad's condition in hospital had deteriorated badly. When I got there he couldn't speak,stay awake for more than half an hour, and I had to try to feed him with a teaspoon. The hospital had used codeine to try to stabilise his stoma and he was on the point of respiratory collapse when we noticed his drug chart , had the codeine stopped, and launched a formal complaint.
As part of their response to that complaint the hospital sent their senior PD specialist to clinically review Dad. She is perhaps the foremost UK PD specialist and before bowel cancer become his number one concern it was his ambition to be seen by Dr khan. He lit up like a Christmas tree when she came to see him and snapped out of his delusions and was fairly lucid. After the exam of Dad I told her I had PD too and she gave me some advice.
Try to keep meds to a minimum. Absolute best thing is regular exercise. Intermittent fasting also good. Tai chi much better than weights for exercise. Use your bad side as much as possible since using that side stimulates some recovery in the brain. She thanked me for participating in research but said not to rely on a pharmaceutical solution. Not what I was expecting from someone in the mainstream.
