Sleep apnea is linked to many physical problems and health concerns, such as type 2 diabetes and cardiovascular disease. While studies indicate a strong link between sleep deprivation and mental health, few clinicians view sleep apnea as a potential cause of depression.sleep apnea and drepression

Why Does Sleep Apnea Cause Mood Swings and Anxiety?

Sleep apnea is a common disorder in which patients repeatedly stop breathing throughout the night. These episodes of paused breathing are called “apneas” and they prevent oxygen from properly circulating throughout the body. If left undiagnosed and untreated, these apnea events can also alter brain chemicals that influence emotion, memory, and cognitive ability. In one study, researchers found two key brain chemicals that were affected by sleep apnea: glutamate and gamma-aminobutyric acid, or GABA.

GABA works to help calm people down while glutamate is directly related to stress. Sleep apnea patients involved in the study had lower levels of GABA and increased levels of glutamate. According to one of the researchers, this means “there must be a reorganization of how the brain is working.”1

Link Between Sleep Apnea, Anxiety, And Depression

Research into sleep and its effect on the brain is ongoing. However, it is clear that there is a connection between mental health and sleep quality. Common symptoms of sleep apnea include:

  • Mood swings & irritability
  • Lack of concentration
  • Mental fogginess

These are also common symptoms of mental health disorders, such as anxiety and depression.

Can Sleep Apnea Cause Depression – What Does The Research Say?

Research on sleep and its effect on the brain is ongoing. One study found that 14% of people being treated for their depression were diagnosed with untreated sleep apnea.2 These patients did not exhibit typical symptoms of OSA, such as daytime fatigue, and a small group of them were non-obese women (sleep apnea typically affects obese men).

As research in the field continues, it is important to understand that to treat depression and other mental health disorders, sleep health must also be examined and treated.
