I live with my mother and father. My mother was recently diagnosed with mixed dementia ( Alzheimer's and vascular dementia). She had been on the anti depressant Sertraline pre-diagnosis for anxiety issues. This did not help her and we believe made things worse. The doctor disputed this but agreed to take her off Sertraline. During this time my mum has become increasingly aggressive towards myself and my father, with episodes of shouting, hitting, kicking, throwing things, and slamming and banging doors. This is normally for no obvious reason and she can be can calm one moment then suddenly snaps. She also is normally only aggressive towards one of us at a time. We are not sure if this is due to withdrawal symptoms from coming off Sertraline or a stage of her dementia. My mother has been approved to take donepezil to help with her anxiety, memory and concentration and prescribed pregabalin to help with anxiety and aggression. Is it too much to hope that my mother's aggressive episodes will reduce or become easier to manage? Also any advice on managing the aggressive episodes would be gratefully received. Thanks in advance and sorry for the long post. This is all so new to us.
