Six years of psychotic symptoms is a long duration. The problem may be undiagnosed schizophrenia
. Sometimes the first-break psychotic episode is triggered by the use of drugs or alcohol and it may take some time before it clears. Some who has a first break psychotic episode like this but then continues to deteriorate may have schizophrenia, a chronic psychotic disorder
that requires aggressive ongoing psychiatric care. This person should certainly consult a psychiatrist
for appropriate care and proper recommendations.
