Have they checked him for depression. Depression can do alot of things. It can mess up your thinking, make you moody. and more i know i have been there and experience it firsthand. You would never think being depressed would work with your body that way but it does. They have checked me for stroke also and it was all due to stress.
Hi,
It is difficult to comment without knowing his complete medical history and results of neurological exam.
It is also important to know if he has undergone an MRI of brain and if yes, there was any positive finding.
Some of the causes of his symptoms include stroke, migraine, brain injury, delirium, MS and parkinson’s disease.
This requires further evaluation and tests by an experienced neurologist to ascertain the right cause.
Thanks
What does the neurologist say?
