My mother is eighty years old. Lately, sometimes she is forgetting what she said two/three hours ago and jumbling up things. Sometimes in the evening she is saying that she has told us certain thing in the morning which she did not say. Otherwise she is fit, roams about in the house with ease, does some cooking and family work and physically and mentally fit. She does not have sugar or pressure. She also seems to acknowledge the fact that she is sometimes forgetting and jumbling up things. Long ago she was diagnosed with heart disease but for the last 22 years she is o.k. Although she takes clopitab 75 mg tablets and stator 10 tablet regularly. Is this an old age problem or she needs some treatment? If yes, then what medicines should she take?
