Strokes run the gamut from TIAs (Transient ischemic attack) with little if any noticeable deficits to strokes that are fatal within minutes. But even a TIA should be evaluated immediately by a doctor at a facility with appropriate equipment. Your acquaintances who have had strokes that didn't cause them difficulties later might not even be aware themselves that they had a stroke.
As I said in another post yesterday my Great Grandmother who raised three of us had in excess of 35 strokes from age 60 until her passing at 98 years of age. We’ve been associated with many others over the years who have had strokes of one degree, or another, and as we are now in our seventies it isn’t uncommon to know someone with such now.
We of course developed experience with “granny” over so long a period to think we know the signs, and sometimes the “signs” aren’t screaming “stroke is happening”, so one has to know rather than depend upon a physical “sign”.
I’m aware of what you are saying, but I am also aware by experience, so I still don’t believe Hillary is having strokes as much as I buy what so many professionals, Doctors are saying about Parkinson’s disease. So many similarities, but definite dissimilarities.
Mrs. JimRed had a TIA a couple of years ago. Scary for a time, but no discernable lasting effects.
