Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.

Obstructive sleep apnea is a condition that prevents proper airflow while one is sleeping. The tissue at the back of the throat will collapse during sleep, which causes a partial blockage of the trachea and hence reducing the amount of oxygen available for distribution to vital organs.
Patients present loud snoring, and may stop breathing for short periods of time – the body wakes itself up when oxygen levels fall critically low. This can happen many times a night without the patient’s full knowledge, meaning that the patient doesn’t enjoy restful sleep. This results in Daytime fatigue and sleepiness.
Other effects include irritability, headaches in the morning, memory loss, decreased libido, impaired concentration and depression. In addition, patients are at a higher risk for suffering heart problems and strokes and are more susceptible to accidents in the workplace or on the road due to impaired concentration.
Diagnosing Sleep Apnea
When a patient sets up an appointment with a sleep apnea dentist, the first step will be to keep a diary of one’s sleeping patterns for two weeks or so. On the day of consultation, an initial interview will be conducted in order to help understand what type of sleep disordered breathing you may be suffering with. A polysomnogram test may need to be performed to examine the heartbeat, brainwaves, limb movements and breathing while the patient is asleep.
The dentist/sleep specialist will also be interested to know any underlying conditions that may interfere with one’s sleeping patterns e.g. drugs and medication, sleep disorders, medical conditions, etc.
Treatment options
There are two main categories that sleep apnea treatments fall under:
1. Oral appliance therapy
2. Upper airway surgery
Oral appliance therapy (OAT)
The dentist will prescribe OAT where patients only present mild to moderate forms of sleep apnea. The first line of treatment is continuous positive airway pressure (CPAP) or fitting an oral appliance to prevent collapsing of the tongue. Behavioral changes are also suggested e.g. losing some weight and changing sleeping posture.
There are various designs for oral appliances, and the dentist will prescribe the most suitable one for your specific needs. In many cases, custom designed appliances will be used as they are more effective than standard OTC appliances. This will only be applied after a certified sleep physician has provided a diagnosis. Fitting of the appliance will be followed by weeks of on-going evaluation to determine efficacy.
Upper airway surgery
This is the last option considered where other less invasive treatments have been unhelpful or are intolerable to patients. There are many surgeries that can be performed, and they are specific to the site of maximum interference. The dentist along with an ENT will help you decide the surgery to be performed depending on the nature and location of obstruction.
Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.
This ‘frequency following’ response of brainwave entrainment can be seen in action with those prone to epilepsy. If a strobe flashes at their seizure frequency, the brain will ‘entrain’ to the flashing light, resulting in a seizure.
On the positive side, this same mechanism is commonly used to induce many brainwave states; such as a trance, enhanced focus, relaxation, meditation or sleep induction. The brainwave entrainment effectively pushes the entire brain into a certain state.
Brainwave entrainment works for almost everyone. It is a great way to lead your mind into states that you might usually have difficulty reaching, allowing you to experience what those states feel like.
THE HYPE
There is a lot of marketing hype around brainwave entrainment. It is sold with promises of increasing IQ, promoting weight loss, ‘mind-tripping’, enhancing creativity, concentration, inducing spiritual states and more.
While these claims are not entirely true, they are not altogether false either. In practice, the claims are based on an overly-simplistic view of how the brain and the brainwaves function.
THE RUB
People are very seldom deficient in a certain brainwave type in all areas of their brain. Usually the distribution is much spottier, with an excess in one area and a deficiency in another.
We are all different, especially when it comes to the distribution of our brainwaves. Boosting a certain brainwave state may be beneficial for one person, and emotionally uncomfortable for another. Without knowing each person’s starting position, entrainment can be rather ‘hit and miss’.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
