It does not hurt but medications are strongly indicated

Yes, absolutely a psychologist can help with schizophrenia. Medications are often a large part of treatment so having a team that includes a psychologist and a psychiatrist is optimal. Some states allow psychologists to prescribe medications as well so that could be an option depending on where you live.

Greetings, The answer to that question is a resounding yes! Psychologists can address both the cognitive deficits (i.e., reduced cognitive flexibility, working memory capacity) that are common with this neuropsychiatric disorder as well as the emotional sequelae associated with the experience of auditory verbal or multimodal hallucinations. They also have a plethora of tools to address idiosyncratic delusional experience.

Greetings,
