Hello....my husband underwent sessions of shock treatment back in the 60's. He is now 68 and seems to be "failing" mentally. He is not depressed, however he has very little energy, sleeps a lot, forgets things, and just "is not there" mentally a lot of the time. I have looked up the symptoms of dementia and I don't see much there that resemble him; I am grasping at straws here: just wondering if anyone had any thoughts of this could be a 50 years after effect of the shock treatment? His doctor said he's fine --not depressed: but I live with him every day and see a marked difference in his personality. Any suggestions anyone? Much thanks.
