Sleep apnea is a serious sleep disorder that causes repetitive stop and start of breath while sleeping.
Sleep apnea is mainly of following three types:
Obstructive sleep apnea: It is the most common form of sleep apnea that occurs when throat muscles relax.
Central sleep apnea: It occurs when brain doesn't send proper signals to the breath controlling muscles.
Complex sleep(Mixed) apnea syndrome or treatment-emergent central sleep apnea: It occurs when someone has both obstructive sleep apnea and central sleep apnea.

Episodes of breathing cessation during sleep witnessed by sleeping partner
Shortness of breath
