10 Symptoms of Insomnia
Symptom #7: Poor Concentration
Poor concentration may be a symptom of insomnia. Lack of sleep impairs your mental capacity so that your mind is unable to function at optimal capacity. This means that memory and learning are impaired. It is not clear how this happens, but studies have confirmed that there is a link between poor sleep and poor focus.
A study of patients with sleep apnea conducted at the University of California found that elevated cortisol levels can lead to poor cognitive function. According to other studies, high cortisol levels have adverse effects on the hippocampus, a structure in the brain that is involved in information acquisition and consolidation into long-term memory.
