My wife who is 77 years of age is prescribed Xet Cr Plus and Buspin 5 by her doctor. She is most of the time restless, repeats herself both in terms of talk and also in action. She has extrem fear complex. She is dia betic for the last 20 years but is under control. She is diagnoised to have Parkinsons decease and Dimentia. She also had silent heat attack about 5 years ago. The Xet Cr Plus and Buspin medicines do not seem to give relief. On the otherhand it is getting worse.She is taking these medicines for the last 4 months. Any suggestions please.
