Hi - don't know if anyone else has had experience with this, but FIL has recently lost lots of weight and has had a change in his normal behaviour to become obsessive over small things - hospital have ruled out cancer (although he has not had a scan - internal exam and blood work) but have not come up with any other reasons - the Geriatric clinic assessed him and he could remember his name, address etc. I am not that impressed with the hospital due to other family members experiences there and wondered any other Mners had had a similar experience with a relative? (He will be 86 in Dec). Wondered if he may have had a mild stroke?, would this also account for the weight loss?
