Snoring
Snoring
Reduced muscle tone in the upper airway during sleep leads to increased resistance to the flow of air, and partial obstruction often results in loud snoring. This symptom may be associated with the obstructive sleep apnea-hypopnea syndrome (OSAHS), which may be associated with a variety of neurological symptoms including excessive daytime somnolence, episodic loss of consciousness, headache (especially morning), cognitive decline, and increased risk of stroke (snoring may be an independent risk factor for stroke).
