Sleep Disturbance Information

Many situations can cause disturbances in your sleep patterns, and often simple lifestyle changes can dramatically help to improve your sleep quality. But while most people experience occasional periods of sleep disturbance, many others suffer from disorders such as chronic Insomnia, Restless Legs Syndrome, Excessive Daytime Sleepiness, and Sleep Apnea. In these cases, your doctor may recommend that you see a specialist in order to diagnose and treat your disorder.

Professional Information

Most people have a primary care physician, particularly with current health care plans. Unfortunately, most of these physicians have not received any training on identifying or treating sleep problems. If the physician were to add just a few screening questions related to sleep to their routine screening assessment, millions of Americans would be guided into a systematic pathway which could improve their sleep ills.

Clinical Approach to Sleep Compaints

Breathing through a narrow airway causes a vacuum that pulls on the throat’s soft tissue causing it to vibrate, which creates the snoring sound.

REM Behavior Disorders Research

REM sleep behavior disorder (RBD) is a sleep disorder in which a patient will physically act out their dreams unknowingly while asleep.

Diagnostic Sleep Testing

Snoring and sleep apnea are extremely common, and patients with these conditions require proper evaluation through diagnostic sleep testing.

Nocturnal Bruxism

Involuntary grinding and clenching teeth at night, known as Nocturnal Bruxism. CSMA can help you resolve this issue and sleep soundly.
