Sleep disorders

085-1308900

Everyone has a sleepless night sometimes. For hours you stare at the ceiling and just don’t fall asleep. If sleep symptoms persist then you may have a sleep disorder.

Types & symptoms

If you have persistent sleep complaints, you may well be suffering from a sleep disorder. The characteristics differ for each sleep disorder. For example, you may sleep too much, or too little. A sleep disorder can also manifest while you sleep. For example, you wake up suddenly sweating and anxious.

Sleep disorders can be divided into 2 general categories.

  1. The amount of sleep you get. These are sleep disorders that are reflected in changes in sleep requirements, sleep duration and sleep rhythm.
  2. Quality of your sleep. These are sleep disorders that are manifested when you sleep and disrupt your sleep stages or sleep functions.

 

Sleep disorders that affect the amount of sleep

This category includes sleep disorders that affect your sleep requirement, sleep duration or sleep rhythm. The most common five types;

  1. Insomnia.
    Insomnia is the medical nomenclature for sleeplessness. Insomnia is when you do not fall asleep, cannot sleep well or simply cannot sleep. It is the most common sleep disorder.
  2. Hypersomnia.
    In hypersomnia, you sleep excessively. You sleep a lot at night, but you are also sleepy during the day and have a lot of trouble staying awake.
  3. Circadian rhythm sleep disorder.
    In this disorder, the circadian sleep rhythm is disturbed. You can think of the circadian rhythm as your internal, biological clock. The biological clock tells you what makes you sleepy or what, on the contrary, makes you awake and alert. With a disturbed circadian rhythm, your sleep rhythm is shifted or disrupted. Think, for example, of jet lag after a trip. In a circadian rhythm sleep disorder, your sleep rhythm is disturbed or shifted, only without a different time zone involved!
  4. Delayed Sleep Phase Syndrome (DSPS).
    In DSPS, your sleep-wake rhythm is shifted to at least two hours later than normal.
  5. Narcolepsy.
    In narcolepsy, you fall asleep suddenly or your muscles slacken. This is often caused by unexpected emotions, for example when you are startled. Narcolepsy is fortunately rare and easy to control with medication and the right lifestyle.

 

Sleep disorders that affect the quality of sleep

In this category, we distinguish three types of sleep disorders; sleep-related breathing disorders, sleep-related movement disorders and parasomnia.

 

Respiratory disorders

This includes sleep disorders involving disturbed breathing during sleep. Breathing is obviously essential and also an automatic process that you cannot control during sleep. The most common disorder in this category is sleep apnoea.

 

Sleep apnoea

With sleep apnoea, during sleep, your breathing may suddenly stop for 10 seconds or longer. This happens because your brain is temporarily deprived of oxygen. Your brain sends a signal to your body to wake up.

  • You can also fall asleep just like that during the day.
  • Often you snore loudly.
  • You don’t get into a deep sleep. This often makes you tired again during the day and ensures that you are not well rested.

 

Sleep-related movement disorders

This category includes disorders where you show uncontrolled movements or experience physical discomfort during sleep. In many cases, the movements are not violent enough to wake you up. Most common disorders are:

  • Restless legs (RLS). Also called Restless Leg Syndrome (RLS). You constantly feel like you need to move your legs (or other body parts) making it very difficult to sleep in and through.
  • Periodic Limb Movement Disorder (PLMD): In periodic limb movement disorder, your legs make violent, jerky movements while you sleep.
  • Teeth grinding.

 

Parasomnia

Parasomnia is the collective term for complaints and symptoms of unwanted behaviour during your sleep. Examples include:

  • Sleepwalking. Your body makes automatic movements while your brain is still asleep.
  • Nightmares. Disturbing dreams that trigger shocking and sometimes even terrible images, emotions and feelings, both during sleep and after waking up.
  • Sleep-drunk. You are conscious but because your body and brain are still half asleep you have no control over your thoughts or movements. This leads to you being able to do strange things and appear ‘clumsy’ or ‘drunk’, sometimes even aggressive, when waking up.
  • Sleep apnea. The body is still asleep, but the brain is already awake. This makes you unable to move.
  • Hypoagnonic hallucinations. Hallucinations occur because control disappears in processing stimuli. Your bodily and mental functions shut down and hallucinations may occur.
  • Pavor nocturnus. Also called “night terror” or “night anxiety. You wake up at night in an anxiety attack for no specific reason.
  • Eating attacks. We distinguish 2 types. In both cases, you wake up several times during sleep with insatiable hunger. Only after eating something do you usually fall asleep again.
    • The ‘Night Eating Syndrom’ or nocturnal eating disorder (NES)
    • ‘Sleep Related Eating Disorders’ or sleep-related eating disorder (SRED)

You don’t necessarily have to have one type of sleep disorder. Your sleep symptoms could be caused by one or more underlying factors.

Are you unsure whether your symptoms are due to ‘regular’ sleep problems or whether one or more sleep disorders are involved after all?
