My 82 year old cousin had a TIA while talking on the phone with her daughter.She said she felt her mouth was full of marbles and now she has to think about her word choice.I have also noticed her asking the same question an hour after it had been answered..like she had never asked it in the first place.Could you discuss TIA’s.which part of the brain it can occur,what is helpful/hurtful,if they are genetic,what causes them to occur.She has had tests and will see the neurologist Monday.Thanks for the insight.My mom also had TIA’s at the same age (though we didn’t know it until further evaluation) and later developed vascular dementia.Thanks!
