Hello Doctor! My father & mother are supposedly suffering from Alzheimer since last 3-4 years & 6-7 years, respectively. The current age of parents is approaching 80 years. My father at times becomes very angry with personnel attending to him or around him for no reasons and then he becomes physical and tries to beat the person. This situation becomes very difficult for the person attending to him. My Q is that whether this behaviour is also related to Alzheimer & what is the remedial/best line of action to handle such situations?
