Sleep Disorders
What Are Sleep Disorders?
Sleep disorders encompass over 80 different conditions that disrupt normal sleep patterns. According to the American Psychiatric Association’s Sleep Disorders Overview, these conditions involve problems with sleep quality, timing, and amount, resulting in daytime distress and functional impairment.
Common Types of Sleep Disorders
Sleep disorders fall into several major categories:
| Category | Examples |
|---|---|
| Insomnia Disorder | Difficulty falling asleep, staying asleep, or waking too early despite adequate opportunity |
| Sleep-Related Breathing | Obstructive sleep apnea, central sleep apnea, sleep-related hypoventilation |
| Hypersomnolence Disorders | Narcolepsy, idiopathic hypersomnia causing excessive daytime sleepiness |
| Circadian Rhythm Disorders | Delayed sleep phase, shift work disorder, jet lag disorder |
| Parasomnias | Sleepwalking, sleep terrors, REM sleep behavior disorder |
| Movement Disorders | Restless legs syndrome, periodic limb movement disorder |
Signs and Symptoms
Sleep disorder symptoms vary but commonly include:
Sleep-Related: Difficulty falling asleep (>30 minutes), frequent nighttime awakenings, early morning awakening
Daytime Effects: Excessive sleepiness, fatigue, irritability, mood changes
Cognitive Impact: Poor concentration, memory problems, decreased work performance
Physical Symptoms: Snoring, gasping during sleep, restless leg sensations, headaches upon waking
Behavioral Changes: Falling asleep during routine activities, requiring frequent naps
What Causes Sleep Disorders?
Multiple factors contribute to sleep disorders:
Medical Conditions: Chronic pain (arthritis, fibromyalgia), respiratory problems (asthma, COPD), neurological disorders
Mental Health: Depression, anxiety, PTSD, bipolar disorder
Lifestyle Factors: Irregular sleep schedules, excessive caffeine or alcohol, screen time before bed
Environmental: Noise, light, temperature extremes, uncomfortable sleeping conditions
Medications: Antidepressants, corticosteroids, decongestants, beta-blockers

How Are Sleep Disorders Diagnosed?
Dr. Budhwar’s evaluation includes:
Sleep History: Detailed assessment of sleep patterns, bedtime routines, and daytime symptoms
Sleep Diary: Two-week record of sleep-wake times, naps, and environmental factors
Questionnaires: Standardized tools like the Insomnia Severity Index or Epworth Sleepiness Scale
Sleep Studies: Polysomnography for suspected sleep apnea or narcolepsy, home sleep testing for milder cases
Treatment Options
Treatment varies by disorder type and severity:
1. Behavioral Therapies
Cognitive Behavioral Therapy for Insomnia (CBT-I): Gold standard treatment combining sleep restriction, stimulus control, and cognitive restructuring
Sleep Hygiene Education: Consistent sleep schedule, optimal sleep environment, pre-sleep routines
Relaxation Techniques: Progressive muscle relaxation, deep breathing, mindfulness meditation
2. Medical Devices and Procedures
Continuous Positive Airway Pressure (CPAP): First-line treatment for moderate to severe obstructive sleep apnea
Oral Appliances: Dental devices for mild to moderate sleep apnea
Light Therapy: Bright light exposure for circadian rhythm disorders
3. Medications
Sleep Aids: Short-term use of zolpidem, eszopiclone for severe insomnia
Melatonin: Natural hormone supplement for circadian rhythm adjustment
Stimulants: Modafinil, armodafinil for narcolepsy and excessive daytime sleepiness
Dopaminergic Agents: Pramipexole, ropinirole for restless legs syndrome
Refer to the NHLBI’s Sleep Disorder Treatments for detailed treatment guidelines.
