This southern WV where it's 94 right now. Mom is sweltering. Can't run central air. They are mid 80s. Dad has mild to moderate dementia and is on very little meds with no med changes recently. He has suffered from cold feet for years when he is inside and has had circulation tests, used creams etc. and uses a heating pad on his feet when indoors. The docs don't have an answer for the feet. Now he is under a blanket while inside and poor mom is wilting from the heat. Is this the dementia or something else going on?
