Insomnia, also known as insomnia, is a sleep disorder where people experience difficulty sleeping. Insomnia may also be a risk factor for depression, and is a symptom of several medical, mental, and sleep disorders.
Insomnia is a common sleeping issue that may impact the quality of your life. Although insomnia is the most common sleep complaint, it is not a unified sleep disorder.
Self-reported problems sleeping, frustrations about the quality of your sleep, and fatigue during the day are the only distinguishing characteristics of insomnia. Other mood disorders, such as bipolar disorder, can cause sleep problems, too.
In fact, insomnia is associated more often with mental health disorders than with any other health condition.
25 For instance, 40% of the insomniacs had a co-occurring mental health disorder compared to 16.4% of the non-sleep-related ones in an epidemiologic catchment area study.8 In addition, depression and anxiety are the most common co-occurring mental health disorders among the insomniacs.
In older adults, stage-advancing syndrome results in reports of difficulty initiating, maintaining, and experiencing waking hours early in the morning.12-14 The most common comorbidity associated with insomnia is psychiatric disorders.
Insomnia, meaning difficulty initiating or maintaining sleep, is a symptom, not a diagnosis, nor is it a disorder. Insomnia is difficulty getting to sleep, or staying asleep for a sufficient period of time so that you feel refreshed in the morning.
Insomnia is a sleep disorder involving difficulties in falling asleep and staying asleep. Sleep-onset insomnia is the difficulty in falling asleep early in the evening, often a symptom of an anxiety disorder.
In fact, although they do not sleep well, patients who suffer from insomnia frequently struggle to get to sleep, even during naps during the day. People with insomnia also do not feel refreshed upon rising from a sleep.
People with insomnia can also experience weaker coping skills, difficulties paying attention and concentrating, memory problems, and trouble performing even routine tasks. Short-term insomnia may cause daytime fatigue, difficulties with concentration, and other problems.
Occasional episodes of insomnia may come and go without causing serious problems, but for some people, insomnia may persist for months and even years.
Insomnia is itself a sleep disorder, but can also be a symptom of other sleep disorders, including sleep apnea, restless legs syndrome, and circadian rhythm disruptions related to jet lag or late-night shifts.
A patients account of insomnia is not specific, and may include various concerns, including difficulty falling asleep, being awakened early or easily, problems getting back into a dream once awake, or overall poor quality of sleep.
Research shows that about 25% of people in the U.S. experience insomnia every year, but about 75% of those individuals do not experience long-term problems.
Insomnia caused by a medical condition is most common among older adults, as people tend to develop more chronic health problems as they get older.
Although insomnia is a common symptom of depression, antidepressants are effective at treating sleep problems, regardless of whether or not the problem is related to depression.
Antidepressants and medications for treating ADHD, hypertension, or Parkinsons also may cause insomnia. Mirtazapine is known to reduce sleep delay (i.e., time taken to fall asleep), improve sleep efficiency, and increase the overall length of time spent sleeping in individuals who have both depression and insomnia.
