Schizophrenia, Psychosis, and Delusions

Psychiatric-mental health nurse practitioners (PMHNPs) play a crucial role in the diagnosis and treatment of schizophrenia, psychosis, and delusions. These conditions, characterized by alterations in perception and reality, pose significant challenges to individuals’ daily functioning. PMHNPs conduct comprehensive assessments, formulate treatment plans, and provide support to individuals experiencing these symptoms. Schizophrenia, a severe and chronic mental health disorder, affects the global population and requires careful management to mitigate its impact on patients’ lives. Delusions, false beliefs despite evidence to the contrary, are common symptoms of schizophrenia and psychosis, requiring targeted interventions. Treatment typically involves a combination of pharmacological and psychosocial approaches, including antipsychotic medications and cognitive-behavioral therapy (CBT). This chapter delves into the assessment, diagnosis, and management of schizophrenia, psychosis, and delusions, encompassing diagnostic criteria, medication options, and therapeutic interventions.
