Sleep Disorders: Causes, Types & Prevention

Types of Sleep Disorders

There are several types of sleep disorders that can affect your overall well-being. Identifying these disorders is crucial for getting the right treatment and improving sleep quality. Common types include:

• Insomnia: Trouble falling asleep or staying asleep through the night.
• Sleep Apnea: Abnormal breathing patterns during sleep.
• Restless Legs Syndrome (RLS): Also called Willis-Ekbom disease, causes discomfort and an urge to move your legs while trying to fall asleep.
• Narcolepsy: Characterized by extreme daytime drowsiness and sudden sleep episodes.

Symptoms of Sleep Disorders

Sleep disorder symptoms can significantly affect your daily functioning and quality of life. Common signs include:

• Difficulty Falling Asleep: Trouble initiating sleep despite being tired.
• Frequent Waking: Waking up multiple times and struggling to fall back asleep.
• Daytime Sleepiness: Feeling drowsy or fatigued even after a full night's rest.
• Restless Sleep: Tossing and turning or disturbed sleep.
• Snoring or Sleep Apnea: Loud snoring or pauses in breathing during sleep.

Causes of Sleep Disorders

Trouble sleeping may result from a range of causes that disrupt the body's natural sleep-wake cycle:

• Physical (such as ulcers)
• Medical (such as asthma)
• Psychiatric conditions (depression, anxiety disorders)
• Environmental factors (like alcohol)
• Working night shifts (disrupts biological clocks)
• Genetics (e.g., narcolepsy is hereditary)
• Medications (some interfere with sleep)
• Aging (common in adults over 65)

When to Visit a Doctor?

If you experience any of the following symptoms, consult a doctor:

• Heavy snoring
• Apnoeic spells during sleep (reported by a partner)
• Falling asleep while driving
• Difficulty staying awake while inactive
• Trouble concentrating at work, school, or home
• Poor performance at work or school
• Frequent feelings of tiredness reported by others
• Memory issues
• Slow reaction times
• Emotional instability
• Daily need for naps

Seek medical attention if you experience one or more of these issues.

Diagnosis of Sleep Disorders

Diagnosis includes physical exams, medical history, and further testing to identify underlying causes.

• Evaluation of contributing factors like snoring, weight, anxiety, depression

Tests Used to Diagnose Sleep Disorders

• Sleep Diary: Logs sleep patterns over time
• Epworth Sleepiness Scale: Measures daytime sleepiness
• Polysomnogram: Monitors sleep activity
• Actigraphy: Wrist device that tracks sleep-wake cycles
• Mental Health Exam: Checks for anxiety, depression, other disorders

Treatment of Sleep Disorders

Treatment varies based on the type and severity of the disorder:

• Lifestyle Changes: Better sleep hygiene, regular schedule, limit caffeine/alcohol
• Cognitive Behavioral Therapy (CBT): Effective for insomnia and negative sleep patterns
• Medications: Short-term sleep aids, prescribed or over-the-counter
• CPAP Machine: Helps keep airways open during sleep (for sleep apnea)
• Relaxation Techniques: Meditation, deep breathing, progressive muscle relaxation
• Surgery: May be required for severe sleep apnea to remove airway obstruction

Prevention of Sleep Disorders

Some sleep issues can be prevented by managing underlying conditions and improving sleep habits:

• Maintain a healthy weight (helps with sleep apnea)
• Make dietary changes
• Exercise regularly
• Practice good sleep hygiene
• Consistent sleep schedule
• Avoid caffeine before bed
