A TIA can and did
cause me the following: felt dizzy, was
vomiting, lost weight, headaches, felt as though he was on a boat and had sea sickness, no energy, sleeping a lot, couldn't concentrate, his vision was odd.
At the time I was 28 years old and active duty army. Athletic ;)
I do not know about hydrocephalus. I posted this in another community for you; hopefully, someone will answer for you.
