Sleep apnea is a common sleep disorder characterized by repeated interruptions in breathing during sleep. These interruptions can last from a few seconds to minutes and may occur 30 times or more per hour. The condition can lead to decreased oxygen levels in the blood, which can have serious health implications. Muscle weakness in the tongue is the main contributor to sleep apnea.

The tongue plays a crucial role in maintaining an open airway during sleep, particularly in the context of obstructive sleep apnea (OSA). OSA is characterized by repeated episodes of pharyngeal narrowing or complete closure during sleep, leading to disrupted breathing and frequent awakenings. The tongue’s position is vital in this process because it can either obstruct or facilitate airflow through the pharynx.

The muscles of the tongue are primarily controlled by the hypoglossal motor neurons, which receive signals from the brain’s preBötzinger complex. This region is responsible for generating respiratory rhythms. When we breathe, these neurons activate the tongue muscles to keep them positioned forward in the mouth, preventing them from collapsing backward into the airway. However, during sleep, especially when lying on one’s back, gravity can cause the tongue to fall back more easily, increasing the risk of airway obstruction.

Research indicates that individuals with OSA often experience reduced activation of these hypoglossal motor neurons during sleep. This reduction leads to a lack of muscle tone in the tongue and surrounding soft tissues, resulting in pharyngeal narrowing or closure. Consequently, this can lead to snoring and significant drops in blood oxygen levels due to interrupted airflow.

Types of Sleep Apnea:
There are two primary types of sleep apnea:

  1. Obstructive Sleep Apnea (OSA): This is the most prevalent form of sleep apnea, occurring when the muscles at the back of your throat relax excessively, causing a blockage in the airway. Factors that increase the risk for OSA include obesity, enlarged tonsils, and anatomical variations in the airway.
  2. Central Sleep Apnea (CSA): This type occurs when the brain fails to send proper signals to the muscles that control breathing. CSA is less common than OSA and is often associated with underlying medical conditions affecting brain function.

There is also a mixed or complex type of sleep apnea that includes features of both obstructive and central sleep apneas.

Symptoms:
Common symptoms of sleep apnea include:

  • Loud snoring
  • Gasping or choking during sleep
  • Excessive daytime sleepiness
  • Difficulty concentrating
  • Morning headaches

In children, symptoms may also include behavioral issues and poor academic performance.

Diagnosis:
To diagnose sleep apnea, healthcare providers typically conduct a thorough evaluation that includes:

  • Medical history review
  • Physical examination
  • Sleep study (polysomnography) to monitor breathing patterns during sleep

The apnea/hypopnea index (AHI) is used to determine the severity of sleep apnea based on the number of apneic events per hour.

BioAcoustic Sleep Apnea Research : We have successfully been able to strengthen the tongue and surrounding muscles and rebalance brain frequencies to stop sleep apnea.
