The symptoms that you have described may be a sign of schizophrenia or a related psychotic disorder. His symptoms may also indicate illicit drug or alcohol use. A third possibility is that his symptoms are indicative of an untreated medical condition. All three possibilities need to be considered and explored.
You believe that he may be willing to go to treatment. That is very encouraging. Individuals who are willing to seek treatment have a more favorable prognosis than individuals who are unwilling to seek treatment.
On your next visit, encourage him to seek help. If possible, offer to attend some appointments with him. The idea is to make him aware of the fact that you’re willing to support him in any way that he needs. He is more likely to seek help if he feels that he has your support.
If he is resistant, remind him that he is loved. You and his son care and rely on him to be well. Inform him that ignoring the problem not only affects him but also you and his son. Reminding him that others rely and care about him may motivate him to receive treatment, even if he is reluctant to do so.
Generally speaking, be loving and supportive but also adamant about the need for help. In the case of psychosis, the importance of early treatment cannot be overstated.
