Hi Fazal,
Thanks for writing in to Healthcare Magic!
You can rather should have bath during periods without any problems.
Your mother had a cerebrovascular attack which has affected a large areas of her Left side of brain.
This area functions to think for us, speech is also lost, weakness would at best recover partially.
If she can walk with support I think she has had the best possible recovery.
Control the BP,
Cholesterol & sugar to avoid recurrence and other complications.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
