My grandmother is 85, and of late, she has started to show signs of cognitive impairment. She talks gibberish and is disconnected from the present. She is immobile and cannot leave home. We consulted our GP who said that nothing can be done because this is happening due to old age. He also said that medicines for mental illnesses are very strong, and since she is frail and weak, she cannot be given such medicines.
Is there nothing that can be done? We're very confused about this situation. Kindly help.
