Mutations in these genes contribute to hearing loss by interfering with critical steps in processing sound. Different mutations in the same gene can be associated with different types of hearing loss, and some genes are associated with both syndromic and nonsyndromic forms.
This kind of therapy is distinct from what is commonly known as sleep hygiene: exercising regularly, but not too close to bedtime, and avoiding coffee and too much alcohol in the evening.

This is typically done in a sleep lab, requiring the patient to spend the night in-lab, while the polysomnography (PSG) equipment records his/her physiological data. However, today with technological advancements a polysomnograpy can be performed at home and is called home sleep testing (HST) or a home sleep study. What are the benefits of Home Sleep Testing? The patient self-administers the home sleep test, and is able to spend the night in the patientâs own bed in familiar surroundings (reducing first night effect).
