What Are Sleep Disorders?

Causes, Symptoms & Treatment

Sleep disorders are problems that occur during sleep, that might disturb and affect your sleep quality and quantity.

This will subsequently affect your daytime activities, work and overall general health.

There are many types of sleep disorders, which include breathing disorders during sleep.

Example of breathing disorders during sleep include obstructive sleep apnoea and central sleep apnoea, where the breathing can suddenly stop during sleep.

Difficulty to sleep (insomnia), excessive sleepiness, jet lag and shift-work disorders are also part of the sleep disorders.

These sleep disorders need to be investigated and treated to ensure your overall good health quality.

Conditions That Can Cause Sleep Disorders

Obstructive Sleep Apnoea

Obstructive Sleep Apnoea

Obstructive Sleep Apnoea is a potentially serious sleep disorder. It causes breathing to repeatedly stop and start during sleep.

Central Sleep Apnoea

Central Sleep Apnoea

Central Sleep Apnoea is a disorder in which your breathing repeatedly stops and starts during sleep.

This condition is different from Obstructive Sleep Apnoea, in which you can’t breathe normally because of upper airway obstruction.

Central Sleep Apnoea is less common than Obstructive Sleep Apnoea.


Narcolepsy is a sleep disorder characterized by excessive sleepiness, sleep paralysis, hallucinations, and in some cases episodes of cataplexy (partial or total loss of muscle control, often triggered by a strong emotion such as laughter).

Narcolepsy occurs equally in men and women and is thought to affect roughly 1 in 2,000 people.

The symptoms appear in childhood or adolescence, but many people have symptoms of narcolepsy for years before getting a proper diagnosis.


Hypersomnia is a condition in which you feel excessive sleepiness during the day. It may occur even after long stretches of sleep. Another name for hypersomnia is excessive daytime sleepiness (EDS).



Insomnia is a sleep disorder in which you have trouble falling and/or staying asleep.

The condition can be short-term (acute) or can last a long time (chronic). It may also come and go.

Acute insomnia lasts from 1 night to a few weeks. Insomnia is chronic when it happens at least 3 nights a week for 3 months or more.

There are two types of insomnia: primary and secondary.

– Primary insomnia: This means your sleep problems aren’t linked to any other health condition or problem.

– Secondary insomnia: This means you have trouble sleeping because of a health condition (like asthma, depression, arthritis, cancer, or heartburn); pain; medication; or substance use (like alcohol).

Periodic Limb Movement Disorder

Periodic Limb Movement Disorder (PLMD)

Periodic limb movement disorder (PLMD) is repetitive cramping or jerking of the legs during sleep. It is the only movement disorder that occurs only during sleep, and it is sometimes called periodic leg (or limb) movements during sleep.

“Periodic” refers to the fact that the movements are repetitive and rhythmic, occurring about every 20-40 seconds.

PLMD is also considered a sleep disorder, because the movements often disrupt sleep and lead to daytime sleepiness.
