My mother in law has become more forgatful in the past several months. She has become difficult to reason wtih and she is usually out of control emotionally and physically. She threatens to harm herself and others near her if she doesn t feel she gets her way. In more recent weeks we have placed her in Nusing facility separated from her husband. She wants to live with him @ home in their home alone which isn t safe for either of them. They are 92 yrs young but feeble and forgetful. She doesn t sleep well and gets up @ night trying to get out her husband is unable to handle her agitation and behaviors. The family is told this is dementia from aging. Is there a diagnosis for this and treatment? Thank You
