hi, I read through your question and understood your problem. -In older ages , falls may occcur due to various reasons: If I were your treating physician I would consider: -(considering his age ) I would like to see if any minimal blood clot is present in his brain or any degenerative changes. by a m.r.i brain and a carotid doppler. along with this, I would rule out if he is having any other factors that may be responsible for falls: - checking his B.P. (low or high , both are causes for giddiness) - muscle power and strength - blood sugar,cholesterol,homocysteine (this will tell us the current status and future risk of stroke) - one of the main reasons for fall in elderly is loss of sense of balance this may be due to age related degeneration of a nerve in the ear. this results in both minimal hearing loss and loss of sense of balance. This is one reason for fall that is most often overlooked but important. a audiometry test can confirm the results If this is the reason for falls ,treatment is effective. -one more reason I would like to look for is cervicalspondylosis,( it is a condition where the bones in the spine of the neck region get eroded and cause changes that decrease blood flow to the brain and cause falls, and on a prolonged basis may cause minimal damage to the brain). -don t worry, once you get a proper diagnosis.you will be more confident about your husband recovery ma am. take care wish ur husband a speedy recovery..!!
