Long story. My dad is currently 75 years old. Diagnosed with prostate cancer at the age of 73 and treated with radiation therapy. didn't handle the cancer diagnosis and treatment well. Got a bladder infection that went untreated, spread to his brain that lead to a 4 month hospital stay, severe depression, and ECT treatment. This all ended in September of 2014. It is now about 1.5 years later. My dad has never been the same, but recent events are making us wonder. about three weeks ago my dad was watching tv while something was cooking on the stove. The food burnt, causing a small fire. Smoke was in the house and the smoke detector was beeping. it didn't seem to phase my dad. My mom ran upstairs and alerted him to the issue and they put it out. Odd he wouldn't react. But in another room watching a soccer game. Maybe focus was elsewhere. One week later my mom went to visit one of her friends. She tell my mother that my dad called her house and was cursing at her and her husband over the phone. These are family friends so no understanding as to why he would ever do that. My mother asked my father about the phone call. He denies ever making them. (call was on a wednesday, my mother confronted him on the following Monday). We checked outgoing calls and sure enough our house did call the friends house on specified day. My mother didn't call them. Again, he denies making the call or having any recollection of calling. To that, these are friends so there is no reason for dad to call them and curse at them. Zoning out, forgetfullness/memory loss, out of character anger. I don't know what to make of this. We were told that there could be longer term side effects from ECT that cause memory loss. he is depressed, no doubt. Just not too sure what to make of it. Doctor recommends that he first get blood and urine work done to rule out infection. We do not have a history of dementia in our family. I don't know what to make of it. When i mentioned the idea of dementia/azheimer's to my dads doctor, he said we are not there yet. Not sure what to make of all this. Very confusing. The worst part is my dad thinks we are accusing him of being crazy and that really brings him down. Anyone ever hear about something like this? I can't find a mental health page so i thought i'd start here.
