Hello. My mother is about 45 years old. She is behaving in odd ways lately. She thinks that our neighbour is plotting against her. All the problems according to her is because of our neighbour.u She thinks all the people in this world is conspiring against her. She is creating a disturbed atmosphere on triffle matters. She thinks except the family members whole world is her enemy. I want to know is my mother a patient of pysciological disorder. Please suggest some remedy for it.
