Sleep disorders are sleeping patterns that often negatively affect the health of an individual. They vary in terms of symptoms and characteristics. Some major sleep disorders are discussed below:
Insomnia
Insomnia is characterized by the recurring difficulty to fall or remain asleep despite motivation and means to do so. People with Insomnia also experience excessive daytime sleepiness and other cognitive impairments while they are awake. Insomnia is considered a chronic condition when patients exhibit symptoms at least three times per week for at least three months. Based on recent statistics, up to one- third of adults live with some form of insomnia. Some types of Insomnia include:
- Sleep-onset Insomnia: Occurs when people have difficulty falling asleep, even when they are tired.
- Sleep maintenance Insomnia refers to difficulty staying asleep during the night.
- Mixed Insomnia is a hybrid condition characterized by sleep-onset and sleep maintenance insomnia symptoms.

Sleep Apnea
Sleep Apnea is a common sleep-related breathing disorder that occurs due to blockage of the upper airway. People with this condition often wake up choking or gasping for air. Heavy snoring is another common symptom. Like other sleep disorders, Sleep Apnea can cause excessive daytime sleep fatigue, as well as various cognitive impairments. Most Sleep Apnea cases fall into one of the following two categories:
- Obstructive Sleep Apnea (OSA) is caused by a physical obstruction that blocks the upper airway. This obstruction may be attributed to large tonsils or adenoids, fluid buildup from advanced heart or kidney failure, or genetic syndromes that affect facial structure such as cleft palate. Obese people with fat deposits around their neck are also at a higher risk of OSA, and sleeping on the back can lead to Apnea episodes if the tongue falls back into the throat. For many patients, Continuous Positive Air Pressure (CPAP) therapy is the most effective treatment.


- Central Sleep Apnea (CSA) occurs when the brain stops sending signals to the muscles that control breathing, leading to choking episodes during the night. As with OSA, obesity is a common risk factor for CSA. The condition may also affect people who have experienced a stroke, brain infection, and other medical problems with the brain stem, as well as those who take narcotic painkillers and other sleep-inducing medications. CPAP (Continuous positive airway pressure) therapy is often prescribed for CSA, though some patients find Bi-level Positive Air Pressure (BiPAP) therapy more effective.
Narcolepsy
Narcolepsy is a sleep disorder that makes people feel excessively tired during the day despite getting an adequate amount of rest the previous night. This can lead to the irrepressible urge to sleep, culminating in “sleep attacks” that typically last for a few minutes. Over time, Narcolepsy can also cause sleep-onset and sleep maintenance problems. The condition known as Narcolepsy Type 1 often includes Cataplexy, or a sudden loss of muscle tone that causes people to fall or slump over as they nod off. Sleep attacks also occur with Narcolepsy Type 2, but Cataplexy is not present.

Restless Leg Syndrome (RLS)
RLS is a type of sleep-related movement disorder that affects people. Also known as “Willis-Ekbom Disease”, RSL is characterized by throbbing, itching, and other painful sensations in the legs and powerful urges to move the legs while they are at rest. People with RLS typically experience the strongest symptoms in bed, putting them at an increased risk for sleep-onset and sleep maintenance problems. There is no cure for RLS, though lifestyle changes, moderate exercise, and nighttime stretching can help some patients manage their symptoms.
Excessive Daytime Sleepiness (EDS)
EDS is defined by feelings of intense grogginess during the day that can compel people to sleep at inopportune times. People who feel excessively groggy during the day may also be more prone to errors and accidents. A wide range of medical and psychological conditions can lead to EDS, such as Diabetes, Hypothyroidism, Chronic Pain, Depression, and Anxiety. Other causes include certain sleep disorders like Sleep Apnea and Periodic Limb Movement Disorder. EDS is believed to affect up to 18% of the world’s population.
Parasomnia
A Parasomnia is a sleep disorder that causes abnormal behavior while sleeping. The behavior can occur during any stage of sleep, including the transition from wakefulness to sleeping and vice versa. Examples are :
Sleepwalking
Sleepwalking, or Somnambulism, is when you walk around while sleeping. It’s a common Parasomnia. It might also involve sleep talking or doing normal activities around the house.
Often, sleepwalking occurs early in the night, although it can happen during daytime naps.
Sleep Talking
Another common Parasomnia is Sleep talking, also known as “Somniloquy.” It happens when you talk while asleep.
Sleep talking can involve a wide range of talking, from mumbling to full conversations.
Unlike Sleepwalking, Sleep talking can happen during any part of the night. The talking is usually easier to understand in the lighter stages of sleep.
Nightmares
Nightmares are troubling, intense dreams that cause anger, anxiety, or fear. If the nightmares frequently occur, it’s called “Nightmare Disorder.”
This Parasomnia can make it difficult to fall back asleep. In some cases, multiple Nightmares may happen in a single night.
Generally, Nightmares occur during REM (Rapid Eye Movement) sleep, when you’re more likely to dream.
A night terrors, or sleep terror, causes you to suddenly wake up in a terrified state. The terror can last from 30 seconds to 5 minutes.
Night Terrors
Night Terrors are also associated with:
- crying
- screaming
- fast heart rate
- sweating
- skin flushing
Unlike Nightmares, Night Terrors usually involve little to no dream activity. Night Terrors also typically happen in non-REM sleep.
Bedwetting
Bedwetting, or Nocturnal Enuresis, is involuntarily urinating during sleep. It’s most common in children, especially in kids younger than 6 years old.
Usually, Bedwetting occurs when the bladder has more urine than it can hold. Some cases don’t have an underlying cause, while others are due to conditions like urinary tract infections.
Confusional Arousal
Confusional Arousal is when you wake up in a very confused state. You might have trouble understanding what you’re doing or where you are.
Other symptoms include:
- slow speech
- poor memory
- crying
- slow reaction time
Teeth Grinding (Sleep Bruxism)
In Sleep Bruxism, you clench or grind your teeth while sleeping. These behaviors can cause:
- tooth pain or sensitivity
- jaw, face, or neck soreness
- earache-like pain
What are the best treatments for sleep disorders?
Depending on the type of sleep disorder you have (with respect to their underlying causes), your doctor may recommend a medical treatment that can include:
- Sleeping pills or Melatonin supplements
- Allergy or cold medication
- Medications for underlying health issues
- An assistive breathing device or surgery (usually for Sleep Apnea)
- A dental guard (usually for Teeth Grinding)
- Tonsillectomy in case of enlarged tonsils which might be obstructing breathing
Apart from the above, making lifestyle adjustments can also improve your quality of sleep, especially when combined with medical treatments. You may want to consider:
- Adding more vegetables and fish to your diet, while reducing sugar intake
- Exercising to reduce stress and anxiety
- Establishing a regular sleeping schedule and sticking to it
- Drinking less water before bedtime
- Limiting caffeine intake, especially in the late afternoon or evening
- Cutting back on tobacco and alcohol use
- Eating smaller, low-carbohydrate meals before bedtime
In all, making good effort towards tackling these sleep disorders will go a long way. Remember, health is wealth!
