How & where can my husband be tested for dementia, Alzheimer’s, or any other underlying condition that might explain the following situations: extreme anger, acting out in public, physical confrontations with family, constant sexual arrousal, inappropriate behavior in front of our grandchildren and forgetfulness. Please note: he is diabetic, he has sleep apnea, & drinking (2 to 3 large cans of beer) which exacerbates all the above-mentioned problems. Am I over-reacting?
