Schizophrenia and Sleep Apnea: Understanding the Connection

Schizophrenia and Sleep Apnea: Understanding the Connection


Schizophrenia and sleep apnea are two distinct medical conditions that can have a significant impact on an individual’s overall well-being. Schizophrenia is a chronic mental disorder characterized by disruptions in thought processes, perception, and emotional responsiveness. On the other hand, sleep apnea is a sleep disorder in which breathing repeatedly stops and starts during sleep.

The Relationship between Schizophrenia and Sleep Apnea

While schizophrenia and sleep apnea may seem unrelated, recent research has uncovered a growing body of evidence suggesting a potential connection between the two conditions. Studies have indicated that individuals with schizophrenia are more likely to experience sleep apnea compared to those without the mental disorder.

Several factors may contribute to this association. One possibility is that the cognitive symptoms associated with schizophrenia, such as impaired attention and memory, can disrupt sleep patterns and lead to sleep apnea. Additionally, certain antipsychotic medications commonly used to manage schizophrenia symptoms can also contribute to weight gain, which is a risk factor for sleep apnea.

Understanding Sleep Apnea

Sleep apnea is a sleep disorder characterized by recurrent episodes of breathing cessation during sleep. There are three main types of sleep apnea: obstructive sleep apnea (OSA), central sleep apnea (CSA), and complex sleep apnea syndrome (CSAS).

Obstructive Sleep Apnea (OSA)

OSA is the most common form of sleep apnea. It occurs when the muscles in the throat fail to keep the airway open, leading to breathing difficulties during sleep. This often results in loud snoring, abrupt awakenings, and poor sleep quality. Individuals with OSA are also at an increased risk of developing other health conditions such as high blood pressure, cardiovascular diseases, and stroke.

Central Sleep Apnea (CSA)

Unlike OSA, CSA is a rare type of sleep apnea that is caused by a malfunction in the brain’s respiratory control center. In this form, the brain fails to transmit proper signals to the muscles that control breathing. CSA is often associated with other medical conditions such as congestive heart failure, brain stem lesions, or stroke.

Complex Sleep Apnea Syndrome (CSAS)

CSAS, also known as treatment-emergent central sleep apnea, is a combination of both OSA and CSA. This occurs when someone with existing OSA develops episodes of CSA after using continuous positive airway pressure (CPAP) therapy to treat their OSA.

Sleep Apnea Symptoms

The symptoms of sleep apnea can vary depending on the type and severity of the condition. Common symptoms include:

  • Loud snoring
  • Choking or gasping during sleep
  • Intermittent pauses in breathing during sleep
  • Excessive daytime sleepiness
  • Irritability and difficulty concentrating
  • Morning headaches

Treating Sleep Apnea in Individuals with Schizophrenia

Given the potential relationship between schizophrenia and sleep apnea, it is essential to address both conditions to improve overall quality of life.

Treatment options for sleep apnea typically include lifestyle changes, such as weight loss, regular exercise, and avoiding alcohol and sedatives. In cases of moderate to severe sleep apnea, continuous positive airway pressure (CPAP) therapy is often recommended. This involves wearing a mask over the nose and/or mouth while sleeping to deliver a constant flow of air, keeping the airway open.

When considering individuals with schizophrenia, it is crucial to evaluate their medication regimen as certain antipsychotic medications can contribute to weight gain and worsen sleep apnea symptoms. Collaborative care between mental health professionals and sleep medicine specialists is advisable to ensure a comprehensive approach to treatment.


While more research is needed to fully understand the relationship between schizophrenia and sleep apnea, the evidence so far suggests a link between the two conditions. Individuals with schizophrenia may be at higher risk of developing sleep apnea, and addressing both conditions is crucial to improving their overall well-being. By raising awareness about this connection and taking a multidisciplinary approach to treatment, healthcare professionals can positively impact the lives of those affected by schizophrenia and sleep apnea.


FAQs about “Schizophrenia Sleep Apnea”

1. Can sleep apnea contribute to the development of schizophrenia?

Sleep apnea is a sleep disorder characterized by interrupted breathing during sleep. While research suggests that individuals with schizophrenia may be at a higher risk of developing sleep apnea, there is limited evidence supporting the idea that sleep apnea directly causes schizophrenia. However, addressing sleep apnea can enhance overall health and potentially improve symptoms in individuals with schizophrenia.

2. How does sleep apnea affect individuals with schizophrenia?

Sleep apnea can exacerbate symptoms of schizophrenia, such as cognitive impairment, poor concentration, and mood disturbances. Additionally, poor quality of sleep due to sleep apnea can worsen the overall well-being and functioning of individuals with schizophrenia. Proper diagnosis and management of sleep apnea can potentially alleviate these negative effects, leading to a better quality of life.

3. What are the common symptoms of sleep apnea and how can it be treated?

Common symptoms of sleep apnea include loud snoring, sudden awakenings accompanied by choking or gasping for air, morning headaches, excessive daytime sleepiness, and difficulty concentrating. Treatment options for sleep apnea may include lifestyle changes, such as weight loss and regular exercise, avoiding alcohol and sedatives before sleep, and using a continuous positive airway pressure (CPAP) machine during sleep, which helps keep the airways open. Seeking professional medical advice is important for accurate diagnosis and effective treatment.
