Insomnia Disorder

Insomnia Disorder is a persistent difficulty with sleep initiation, duration, consolidation, or quality, occurring despite adequate opportunity for sleep. It results in significant daytime impairment, such as fatigue, mood disturbances, cognitive deficits, and decreased professional or social productivity. It is classified under sleep-wake disorders in the DSM-5.

Etiology is multifactorial, involving a 3P model: Predisposing factors (genetics, personality), Precipitating factors (stressors, acute trauma), and Perpetuating factors (napping, conditioning, sleep anxiety). Lifestyle factors include poor sleep hygiene, caffeine/alcohol intake, and irregular circadian rhythms.

Pathophysiology centers on hyperarousal. Neurobiologically, there is an overactivity of the ascending reticular activating system and the hypothalamic-pituitary-adrenal (HPA) axis. Imaging reveals reduced GABAergic inhibition and altered connectivity in the default mode network, maintaining a state of cortical arousal during nocturnal hours.

Insomnia affects approximately 10–30% of the general population. It is more prevalent in women, older adults, and individuals with comorbid psychiatric or medical conditions. Chronic insomnia affects roughly 10% of adults globally.

• Advanced age
• Female gender
• High baseline anxiety or depression
• Shift work or irregular schedules
• Chronic pain conditions
• Substance use

A. Early Symptoms

• Difficulty falling asleep


• Mind racing at night


• Increased worry about sleep B. Common Symptoms


• Frequent nocturnal awakenings


• Daytime fatigue


• Irritability


• Difficulty concentrating C. Advanced Symptoms


• Chronic exhaustion


• Significant mood swings


• Impaired motor coordination


• Memory impairment D. Emergency Symptoms


• Acute psychosis

Physical exams are typically unremarkable but may show signs of chronic stress: elevated resting heart rate, dry mucous membranes, or tremor.

A. Clinical Assessment: Sleep diary for 2 weeks, validated scales (ISI, PSQI).
B. Laboratory Testing: Thyroid panel, CBC to rule out physiological causes.
C. Imaging Studies: Generally not indicated unless ruling out organic brain lesions.
D. Functional Tests: Polysomnography (only if sleep apnea or periodic limb movement disorder is suspected).
E. Biopsy Findings: N/A.
F. Genetic Testing: Not routinely used.
G. Differential Diagnosis: Sleep apnea, restless leg syndrome, circadian rhythm disorders.

Thyroid Stimulating Hormone (TSH)
Type: Blood Test
Purpose: Rule out hyperthyroidism
Expected Findings: Normal range
Interpretation: High/low values suggest metabolic causes of sleep disturbance

Polysomnography: Used to rule out obstructive sleep apnea and other sleep architecture abnormalities; essential for complex cases.

Distinguished from sleep apnea by the absence of witnessed apneas or snoring; distinguished from restless leg syndrome by the absence of limb discomfort before sleep onset.

• Hypertension
• Type 2 diabetes
• Impaired immune function
• Increased risk of vehicular accidents

A. Lifestyle Modifications: Sleep hygiene, stimulus control therapy.
B. Preventive Measures: Consistent sleep-wake schedule.
C. Medical Treatment: - Benzodiazepine receptor agonists (e.g., Zolpidem)

• Orexin receptor antagonists (e.g., Suvorexant)


• Melatonin receptor agonists (e.g., Ramelteon)

Good with early intervention. CBT-I is the gold standard, offering long-term remission. Chronic, untreated insomnia may lead to secondary depression.

Primary: Proper sleep hygiene. Secondary: Early intervention at the first sign of chronic sleep difficulty.
