Central sleep apnea is a sleep disorder where the brain fails to send proper signals to the muscles that control breathing. Unlike obstructive sleep apnea, which is caused by a blockage in the airway, central sleep apnea occurs when the brain temporarily stops signaling the body to breathe during sleep. This can lead to interrupted sleep and reduced oxygen levels in the blood. This condition can affect anyone but is more common in people with certain medical conditions, such as heart failure or stroke. Treatment options may include continuous positive airway pressure (CPAP) therapy, lifestyle changes, or addressing underlying health issues.
