Although it is normal to experience problems sleeping, these disturbances are usually quickly resolved. A sufferer of a sleep disorder will struggle to fall asleep as a regular occurrence, thus not being able to cycle through the stages of sleep.

 

This leads to an inability to rest and restore energy, which often leads to problems with communication, relationships, concentration, decision making, work responsibilities, and/or general daily functioning. A lack of sleep can create significant emotional upheaval, including increased irritability, agitation, and anxiety.
