My Dad Is In A Nursing Home And Has Become

My dad is in a nursing home and has become depressed and has started acting out aggresively and sometimes making sexual advances by touching women. He has Parkinsons Disease and is on LevoDopa and carbodopa. They are starting him on Zypera tonight and I worry about the sides effects. THey tried seroquel once and he become very disoriented and started crying. What do you recommend that they put him on? If we don't find something that works they will force him to leave the nursing home.
