I believe your concerns are valid. Your brother believes in things that aren’t true despite evidence to the contrary. That is the definition of a delusion. He also seems to be paranoid. Delusions and paranoia are symptoms of psychosis. Though he is exhibiting symptoms of psychosis, I cannot determine with certainty whether or not he is psychotic. Only an in-person, mental health evaluation could properly make that determination. Nevertheless, his symptoms are concerning.
Continue to encourage your brother to seek help. You should also discuss your concerns with your family and perhaps you, as a group, could convince him to seek help. If there are friends of his that you can include, this might help as well. Do everything within your power to convince him to seek professional help.
It’s important to realize the limits of your power in this situation. Continue to try to convince him to seek help but recognize that he has the right to say no. Generally speaking, adults cannot be forced into treatment unless there is evidence that they are a danger to themselves or to others. That is the nature of the mental health laws in the United States.
If you believe that he is a threat to himself or to others, then you should call the authorities. Another option is to call the local mental health crisis team who will come to the home, assess your brother’s condition and determine if he needs to be hospitalized. If they believe that he needs to be hospitalized, they will take the necessary steps to commit him.
In the meantime, try to do all that you can to convince your brother to consult a mental health professional. That may include you finding a healthcare provider for him or going to the appointment with him, if he would allow. He may be open to those things. Another option to consider is family therapy. He may be open to that form of treatment because all members of the family could attend the sessions, not just him alone. Your family may have other ideas as well.
I hope this answer assists you in knowing how to proceed with your brother. I wish I had a better answer for you with regard to how to best help your brother. The reality is that people have the right to refuse treatment in this country even if they are clearly mentally unstable. Until this changes, your power is limited. If you have additional questions, please don’t hesitate to write again. Please take care.
