linsomnie

Linsomnie is not a formally recognized medical diagnosis in major sleep-disorder classifications such as the DSM-5 or ICD-11. It is most often encountered as a misspelling or nonstandard variant of insomnia, a condition defined by difficulty initiating or maintaining sleep, or by non-restorative sleep, despite adequate opportunity for sleep. When used, the term generally refers to the same spectrum of sleep disturbances associated with insomnia.

Common symptoms include trouble falling asleep at bedtime, frequent awakenings during the night, early morning waking with inability to return to sleep, and non-restorative sleep leading to daytime fatigue, concentration problems, and irritability. Insomnia can be described as acute (short-term) or chronic (lasting three months or longer), and as primary (not directly attributable to another condition) or secondary (linked to medical, psychiatric, or substance-related factors).

Causes are multifactorial and may include psychological stress, anxiety or depression, medical illnesses, chronic pain, medications, caffeine or alcohol use, and irregular sleep schedules or shift work. Diagnosis is clinical, based on patient history and sleep patterns. A clinician may use sleep diaries and questionnaires, and may assess for other sleep disorders such as sleep apnea, restless legs syndrome, or circadian rhythm disturbances.

Treatment centers on evidence-based approaches such as cognitive behavioral therapy for insomnia (CBT-I), which addresses thoughts about sleep, stimulus control, sleep restriction, relaxation strategies, and good sleep hygiene. Pharmacotherapy may be considered for short durations under medical supervision; options include certain sedative-hypnotics, melatonin, or other agents, with careful attention to risks and dependence. Insomnia symptoms are common in the general population, and chronic insomnia affects a minority of adults, with prevalence estimates around 10–15% depending on criteria and population.
