###Human: Kindly advise the measures to be taken to manage OCD and PTSD patient? ###Assistant: Hello. Your friend's mother is showing an aggressive and abusive behavior which indicates serious mental illness. There can be an element of delusion of persecution that is suspiciousness of being killed by her son, which is making mother so violent. I would advise you to tell your friend that he should consult a psychiatrist, his mother may require in-patient treatment. We have very good medicines available nowadays which can control every patient. More the time lapse without treatment, more resistant will be the disease. So it is better to start the treatment as soon as possible.
