My dad seems to be between stage 4 and stage 6 with Alzheimer's disease. My step-mother does not seem to understand the importance of having him see a specialist. I scheduled an appointment with her and my dad at a geriatric assessment center. This assessment requires two visits. One with a social worker and the second with a psychiatrist. After the first appointment my step-mother went to a PCP appointment with my dad. She said the PCP suggested the same tests would be done that he already did and adding another doctor to the doctors he already sees, would confuse him. So, she canceled the second appointment I scheduled. My father has no POA or medical powers created. His PCP will not discuss my dad's health with me without a HIPPA form signed. Does anyone have any suggestions to ease my frustrations? I feel my step-mother's actions are harming my dad's wellbeing.
