DSM-5 · F51

Sleep Disorders

Sleep disorders disrupt the quality, timing, and amount of sleep, leading to daytime distress and impaired functioning.

DSM-5 Clinical Definition

"Dissatisfaction with sleep quantity or quality, associated with difficulty initiating sleep, maintaining sleep, or early-morning awakening with inability to return to sleep."

Sleep disorders encompass a range of conditions including Insomnia Disorder, Hypersomnolence Disorder, Narcolepsy, Circadian Rhythm Sleep-Wake Disorders, and Parasomnias. Insomnia is the most common, affecting approximately 10–30% of adults. Sleep disorders are closely linked to psychiatric conditions — they can both cause and worsen depression, anxiety, ADHD, and bipolar disorder. Addressing sleep is often a critical component of comprehensive mental health treatment.

Signs & Symptoms

Symptoms vary by individual. A clinical evaluation is required for diagnosis.

Difficulty falling asleep

Lying awake for 30 minutes or more before falling asleep, despite feeling tired.

Frequent night waking

Waking up multiple times during the night and having difficulty returning to sleep.

Early morning awakening

Waking up significantly earlier than desired and being unable to fall back asleep.

Non-restorative sleep

Waking up feeling unrefreshed despite adequate time in bed; persistent daytime fatigue.

Daytime impairment

Fatigue, mood disturbance, difficulty concentrating, reduced motivation, or increased errors at work or school.

Sleep-related anxiety

Worry about sleep itself, clock-watching, and performance anxiety around bedtime that perpetuates insomnia.

Evidence-Based Treatment

At Wellness Behavioral Health and Healing PLLC, treatment plans are individualized and grounded in the latest psychiatric evidence. Options may include:

  • Cognitive Behavioral Therapy for Insomnia (CBT-I) — first-line treatment
  • Sleep restriction therapy and stimulus control
  • Sleep hygiene education and circadian rhythm optimization
  • Short-term sleep medications (trazodone, mirtazapine, low-dose doxepin)
  • Melatonin receptor agonists (ramelteon) for circadian disorders
  • Treatment of underlying psychiatric conditions contributing to sleep disruption

When to Seek Help

Seek help when sleep problems occur at least 3 nights per week for 3 months or more, cause significant daytime impairment, or are not explained by another medical condition. Poor sleep significantly worsens all mental health conditions.
