My husband is 78 and diagnosed with mild cognitive Impairment/early dementia. Over the last three months he has become extremely lethagic. I try to plan activities but he doesn't have any interest in most. He only gets up to eat. Last night he slept on the couch; it is almost 6 in the afternoon and he has not moved. He has not bathed in 4 days or shaved in 2 weeks. He is on an antidepressant, his second one. I am feeling very frustrated and tearful...do not know how to handle this.
