Hello Doctor, My father is 65 years old. In the last 2 years, his voice has suddenly become feeble and he seemed forgetful. His walking was also very slow. However, he did not have any fainting/tremors etc. About 6 months back, we saw a neurologist and we started using tables like Syncapone, Parkitidin, Torleva and pentocid. Ever since we started these, he keeps fainting/falling. The falls are not slipping or just falling down. He becomes unconscious. And then his head and hands keep shaking for no reason. But his memory seems fine now. He remembers everything, has opinions on politics, current affairs, cash etc. But we are scared to let him step out by himself. Please help us.
