Sleep Disturbances: Insomnia, Sleep Apnea & How Doctors Treat Them Today
Poor sleep is one of the most common health problems at all. According to gesundheitsinformation.de, about a third of all people struggle with sleep problems, about 6 % have a clinically diagnosed sleep disorder. Women are more often affected than men. What distinguishes normal sleep problems from a treatable disorder?
What is a sleep disorder? The medical definition
A sleep disorder exists when:
- In at least 3 nights per week
- Over a period of more than one month
- Sleep problems occur that measurably impair quality of life or daily function
Sometimes having trouble sleeping – during stressful phases, before important events – is normal and not a disorder.
Insomnia: The most common sleep disorder
Insomnia is the overarching term for difficulties falling asleep and staying asleep, as well as waking up too early. It is the most common sleep disorder worldwide.
| Type | Definition | Frequency |
|---|---|---|
| Acute Insomnia | Several days to weeks, usually triggered by stress/event | Very common, usually self-limiting |
| Chronic Insomnia | 3 times/week, over 3+ months, with daytime impairment | ~6–10 % of the population |
| Comorbid Insomnia | Accompanying depression, anxiety disorders, pain | Common – often interaction |
Typical symptoms: Long sleep latency (>30 Min.), frequent nighttime awakenings, early awakening without returning to sleep, non-restorative sleep despite sufficient sleep time, daytime sleepiness and concentration problems.
Sleep Apnea: When Breathing Stops During Sleep
In sleep apnea (obstructive sleep apnea, OSA), the throat muscles relax during sleep and block the airways. Harvard Health: “People stop breathing for short periods.” This can happen 10–30 times or more per hour.
Warning signs:
- Loud, irregular snoring
- Observed apnea episodes (reported by partner)
- Morning headaches
- Extreme daytime fatigue despite sufficient sleep
- Frequent nighttime awakenings with choking or suffocation sensation
Sleep apnea is not just a sleep problem: Untreated, it significantly increases the risk of high blood pressure, heart rhythm disorders, stroke, and type 2 diabetes.
Restless Legs Syndrome (RLS)
RLS is a neurological syndrome characterized by an irresistible urge to move the legs (rarely arms), which mainly occurs during rest and in the evening or night. The urge subsides with movement – but returns immediately when lying down again.
RLS is often underdiagnosed and is frequently dismissed as nervousness or muscle cramps. Iron deficiency is a common treatable cause.
Overview of Other Sleep Disorders
- Hypersomnia: Excessive daytime sleepiness despite normal sleep duration
- Narcolepsy: Sudden sleep attacks during the day, often with loss of muscle control
- Parasomnias: Sleepwalking, sleep terror, REM sleep behavior disorder
- Circadian rhythm sleep disorders: Strongly shifted sleep-wake rhythm
Diagnosis: How do doctors proceed?
According to gesundheitsinformation.de, the diagnosis begins with a detailed doctor’s consultation. Common steps:
- Keep a sleep diary for 2 weeks
- Blood test (thyroid, iron, vitamin D)
- Sleep questionnaire (Epworth Sleepiness Scale)
- Sleep lab (polysomnography) if apnea, RLS or parasomnias are suspected
Treatment: What really works
Cognitive Behavioral Therapy for Insomnia (CBT-I)
Harvard Health and all evidence-based guidelines: CBT-I is the first-line treatment for chronic insomnia – more effective than sleeping pills, without side effects and with long-lasting effects. CBT-I includes sleep restriction, stimulus control, cognitive restructuring, and relaxation techniques.
Pharmacological treatment (second-line)
According to Cleveland Clinic and Harvard Health: Sleep medications are not a long-term solution. The following are used:
- Z-Drugs (Zolpidem, Zopiclone): Effective in the short term, potential for dependency
- DORAs (Daridorexant, Lemborexant): Newer class, blocks orexin (wakefulness signal)
- Low-dose antidepressants (Doxepin, Mirtazapine): For comorbid depression
- Melatonin agonists (Ramelteon): For circadian rhythm disorders
CPAP for sleep apnea
Continuous Positive Airway Pressure (CPAP) is the gold standard. A mask keeps the airways open through mild positive pressure. Weight loss can in some cases fully cure apnea. Surgical options (uvulopalatopharyngoplasty, hypoglossus nerve stimulator) in case of CPAP failure.
Frequently asked questions about sleep disorders
How can I tell if I have sleep apnea?
Loud snoring with irregular pauses, extreme daytime sleepiness, and morning headaches are typical signs. Only a sleep lab examination can confirm it.
Can insomnia go away on its own?
Acute insomnia (triggered by stress, illness, or an event) often resolves on its own. Chronic insomnia (lasting more than three months) usually requires active treatment – it rarely improves without intervention.
Are sleeping pills dangerous?
Prescription sleeping pills such as benzodiazepines have a real potential for dependency and alter sleep architecture. For older people (over 65), many classical sleeping pills are not recommended due to an increased risk of falls. Newer drug classes (DORAs) are better tolerated, but more expensive.
