Investigation of Using Non-Wearable Devices to Assess Sleep- Disordered Breathing in Hospitalized Patients With Schizophrenia

This study is using non-wearable bedside devices to monitor breathing during sleep in hospitalized patients with schizophrenia, to look for signs of sleep apnea (interrupted breathing during sleep). The goal is to see whether these devices can accurately detect sleep-disordered breathing in this population. **You may be eligible if...** - You are between 20 and 70 years old - You have a diagnosis of schizophrenia, schizoaffective disorder, or schizophreniform disorder (confirmed by a structured interview) - You are in a relatively stable condition at admission and able to give informed consent (or a family member can consent if needed) **You may NOT be eligible if...** - You are already using a CPAP machine for sleep apnea - You have another major brain or mental health condition (such as major depression or bipolar disorder) - You have a serious physical illness that affects breathing or movement - You have uncontrolled epilepsy - You are too agitated or uncooperative to safely participate Talk to your doctor to see if this trial is right for you.
