Hello,
As she is 70, this is one of the common problems which most females face at that age of low blood pressure. Also, she must be having a kind of parkinsonism symptoms. There is a difference between Parkinson's disease and parkinsonism. As one is a pathology related to the
dopamine secretion with rigidity and tremors and the other is having trouble with the ageing of the brain leading to
dizziness low blood pressure weakness shaking etc.
I will advise to make her walk as much as possible, improve the cognitive levels, make her get involve into the normal conversation at home, give the medicine prescribed, make her do some breathing exercises, simple low-intensity general body exercises.
In cases at the age of 70, these symptoms are normal and with proper care and medications, she should have a normal life.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Jay Indravadan Patel, Physical Therapist or Physiotherapist
