New research examines the brains of people with schizophrenia and finds disrupted patterns of expression in genes linked with sleep-wake cycles.
Worldwide, schizophrenia is one of the top 15 leading causes of disability, affecting about 1% of the world’s population.
In the United States, slightly more than 1% of adults, about 3 million, may be living with schizophrenia, according to some estimates.
The condition causes several symptoms, including impaired thought processes, emotions, and social behavior. People with schizophrenia also frequently experience insomnia and disrupted sleep-wake cycles.
