My father (87) constantly complains of one physical ailment or another. Leg pain, chest pain, dizziness, stomach ache, etc. All medical test show he is physically healthy for his age. He was diagnosed with dementia about 6 months ago. He has episodes of repeating questions, sleeps a lot, will not socialize with friends, very negative and needy. Is the pain real in his mind or is it a tactic for attention?
