Hi, I can understand what you might be going through. You haven t mentioned whether your mother is on any treatment as of now and what are the exact symptoms she is suffering from as of now. I would advise you to consult a neurologist first. Thorough evaluation with blood investigations, cardiac evaluation and brain scanning would be needed to determine any primary cause of dementia. She would need treatment with medicines like donepizil which will slow down her progressive cognitive decline. In addition, if she is having any behavioral symptoms, medications might be required for that too. She could also be helped by certain behavioral measures for her memory symptoms. You can discuss this with the neurologist. Hope this information was useful. Best wishes.
