Mom has shown signs of Dementia for at least 2 yrs. Dad & I have managed to get blood work, a cat scan, & a trip to the E R. done. She lied her way through all evaluations & nothing abnormal showed on medical tests. She has awful behaviour with dad, jealousy, thinking he poisoning her, yelling at him everyday. They're both 76. Is it time to get a court order to get get her on meds? We both want her to stay at home, just be more manageable. She stays with me a few days here & there, but now doesn't like my husband. Help please.
