Common Sleep Disorders And Understanding The Anatomy Of Sleep

Most individuals will experience trouble with their sleep. However, it is crucial to get a sleep specialist in Singapore to assess if you or someone you know is struggling with the following:

Insomnia

The struggle to initiate or maintain sleep is characterised by insomnia. A person may also have an early morning awakening, in which case they cannot go back to sleep after waking up.

Excessive daytime sleepiness, which typically leads to functional impairment during the day, is a frequent indicator of difficulty initiating or maintaining sleep. Prior to making a diagnosis of primary insomnia, the sleep specialist will rule out any other possible reasons, such as: 

• 
  Other sleep disorders
• Medication side effects
• Substance abuse
• Depression
• Other undiagnosed illnesses

Stress, paired with the worry of being unable to sleep, might cause chronic psychophysiological insomnia. People with this disorder might sleep better outside of their own beds.

Narcolepsy

The defining symptoms of narcolepsy include excessive daytime sleepiness and abrupt muscle weakness. Strong emotion or surprise may trigger the sudden muscular weakness associated with narcolepsy.

Narcolepsy episodes have been referred to as "sleep attacks" and might unexpectedly happen while doing things like walking or other physical activities. To reduce the possible impact of narcolepsy on the individual's life, the sleep specialist may address it using stimulant medications paired with behavioural measures such as regularly planned naps.

Restless Legs Syndrome (RLS)

Restless legs syndrome (RLS) is distinguished by an uncomfortable "creeping" sensation that appears to begin from the lower legs and is frequently linked with aches and pains throughout the legs. This often makes it difficult to fall asleep and is eased by leg activity, such as walking or kicking.

RLS has frequently been linked to dopamine neurotransmitter abnormalities. When treating RLS, sleep specialists often pair a medicine that helps address the underlying dopamine imbalance with medication to support sleep continuity.

Sleep Apnea

Rather than just being an irritating habit, snoring may be a sign of sleep apnea. Individuals who suffer from sleep apnea frequently make "snorting" or gasping noises, which briefly disturb their sleep.

Due to frequent sleep interruptions and possible restless sleep, people with sleep apnea may also develop excessive daytime sleepiness. The cause of sleep apnea will determine how it is treated.

Sleep apnea symptoms should be handled carefully since irregular breathing interruptions or airway obstruction while sleeping can significantly affect health. A sleep specialist should be consulted for treatment.

Sleep Anatomy

Sleep involves a number of different brain structures.

Hypothalamus

Groups of nerve cells acting as control centres for sleep and arousal are found in this peanut-sized structure located deep inside the brain. The suprachiasmatic nucleus (SCN) is located inside the hypothalamus. There is a group of hundreds of cells that regulate your behavioural pattern by directly receiving information from your eyes regarding light exposure.

Brain stem

To stabilise the transitions between wake and sleep, the brain stem, situated at the base of the brain, works with the hypothalamus. A brain chemical called GABA is produced by sleep-inducing cells in the hypothalamus and brain stem. GABA minimises the activity of arousal centres in the hypothalamus and brain stem.

In order to prevent us from acting out our dreams, the brain stem also plays a specific role during REM sleep by sending signals to muscles necessary for posture and limb movement.

Thalamus

Data from the senses is transmitted to the cerebral cortex through the thalamus. The thalamus quiets down during the majority of the stages of sleep, allowing you to tune out the outside world.

However, the thalamus is active during REM sleep, sending the cortex visuals, noises, and other sensations that make up our dreams.

Pineal gland

When the lights go out, the pineal gland–situated between the two hemispheres of the brain–increases the secretion of the hormone melatonin by responding to signals from the SCN.

Individuals who have lost their vision and are unable to match their normal wake-sleep cycle with natural light can regulate their sleep habits by taking small quantities of melatonin at the same time every day.

Basal forebrain

While the midbrain serves as an arousal mechanism, the basal forebrain, positioned close to the front and bottom of the brain, also encourages sleep and wakefulness. Your need to sleep is supported by the production of adenosine, a chemical by-product of cellular energy, used from cells in the basal forebrain and possibly other locations.

Amygdala

During REM sleep, the amygdala, an almond-shaped brain region involved in emotion regulation, becomes more active.

Improve Your Health With Better Sleeping Habits

Sleep disorders may not be fatal, but they have such a negative impact on your quality of life that they can impair a few aspects of your life, including: 

• Your ability to think clearly
• Managing your weight
• Performing well at work or school
• Maintaining good mental and physical health

Consult a sleep specialist in Singapore right away if you're having issues falling or staying asleep. Sleep is essential for your health and, consequently, your quality of life. Maintain proper sleep hygiene and follow the advice of your sleep specialist.
