Dear doctor, My mother, 85 years old, stays mostly in bed, is, now-a-days constantly talking alone, using abusing words to someone she can t see but hears. When asked, she complains that some people are loudly announcing to cause harm to her sons and gran children. She says, these threatening come through cell phone signals, through TV signals, through electrical wire in the room. Initially, it used to be only while TV is on next room. Now, she talks all the time, mostly after breakfast and lunch, except when she is sleeping. She sleeps early in the evening and she continues talking after she is woken up for dinner till very late in the night. Psychiatrist has prescribed Olimelt 2.5 mg two times (morning and evening). This dose is continued for four days. but there is no apparent improvement in her behaviour, except that she is sleeping in the morning also for sometime. Please help. AAAAAAA
