Dear Dr. I would like to ask about my mother s health. she is a diabetic patient. But, since a couple of years she behaves like an abnormal human being. There are multiple reasons to mention such kind of words about her behavior. Whenever my father talks with any lady, she think that my father has some relationship with that lady[this is a common tendency all the time]. She fights with the neighbor [ladies] for all small matters. In her eyes if any lady talks with my father then she had a relationship with my dad. I hope you might be understand about the situation. Now-a-days its very tough to handle the situation. Kindly, could you please help me out. Is it a kind of mental illness? How to handle this situation? Should we consult with any psychiatric doctor? Kindly suggest me. Thanks and regards, Saahil
