What are sleep disorders and how do they manifest?

A lot of people face sleep problems, so it is crucial to take care of our sleep regime and be cautious in avoiding health problems caused by it.

What are sleep disorders?

Sleep disorders are a group of conditions that affect a person's ability to sleep well on a regular basis, with restless sleep.

Whether caused by a health problem or too much stress, sleep disorders are increasingly common among adults and are a common problem worldwide. Let's see what the most common sleep disorders are and what can be done to manage them.

It is important to know what sleep disorders are and how they manifest, in order to be able to identify them in time and treat them.

Sleep disorders are divided into:

1. dyssomnias
2. parasomnias
3. Sleep disturbances associated with medical disorders

The category of dyssomnias includes:

• Insomnia: Insomnia is manifested by inadequate sleep, which can be perceived as difficulty falling asleep, frequent awakenings, morning awakenings or persistent drowsiness. Psychophysiological insomnia is a behavioral disorder in which patients are preoccupied with a perceived inability to sleep well at night. They may fall asleep easily outside of their set hours or in unusual sleep environments. Altitude insomnia occurs when the person is exposed to high altitudes, while situational or transient insomnia occurs when the sleeping environment changes.
• Alcohol- and drug-dependent sleep disorders: Caffeine is the most common pharmacological cause of insomnia. Alcohol and nicotine can also cause insomnia, although some patients use them to induce sleep.
• Narcolepsy: This is characterized by excessive daytime sleepiness and restless sleep at night, including terrifying hallucinations when falling asleep or waking up, sleep paralysis, cataplexy (sudden loss of muscle tone without loss of consciousness, caused by emotions) and memory loss.
• Sleep apnea syndromes: These are a common cause of daytime sleepiness and nighttime sleep disturbances. Apnea, or cessation of breathing, occurs due to upper airway obstruction or lack of respiratory effort. Sleep apnea is common in overweight men and elderly people with high blood pressure.
• Dyssomnia associated with limb movement: Includes restless legs syndrome and periodic limb movement such as nocturnal myoclonus. Restless legs syndrome is manifested by an acute need to move the legs before sleep or upon awakening, and nocturnal myoclonus involves stereotypical movements of the fingers and legs, causing frequent awakenings.

• Parasomnias: These are behavioral disturbances during sleep, associated with short, partial awakenings without total interruption of sleep. Examples include sleepwalking, terrifying dreams or night terrors, and REM sleep behavior disorders. Nocturnal bruxism involves involuntary teeth grinding and nocturnal enuresis refers to bedwetting.

Sleep disorders associated with medical conditions or psychiatric disorders:

• Sleep disturbances associated with psychiatric disorders. In schizophrenia, the sleep-wake rhythm is reversed and sleep is fragmented and insomnia occurs. Patients with anxiety, affective disorders, obsessive-compulsive disorders or chronic alcoholism sleep little. In the case of mental depression, insomnia occurs at the onset of sleep and waking up very early in the morning, which are important and early signs of depression. In mania and hypomania , sleep duration is reduced. Chronic alcoholics do not have slow NREM sleep, they only have REM sleep, they wake up frequently at night, they are sleepy during the day, and these disorders persist for years after the cessation of alcohol consumption.
• Sleep disorders associated with neurological disorders. Pain from various neurological conditions can disrupt sleep. Dementias are associated with disturbances in the synchronization of the sleep-wake rhythm, called "night wanderers". In the case of those who suffer from epilepsy , seizures may occur during sleep.
• Sleep disorders associated with medical conditions. Among the most important conditions associated with sleep disorders are bronchial asthma, cardiac ischemia, chronic obstructive pulmonary disease (COPD), menopause, hyperthyroidism, gastroesophageal reflux, chronic renal failure , and liver failure .

The Impact of Sleep Disorders on Health

Short-term consequences

Sleep disturbances have significant immediate effects on health. Daytime sleepiness is one of the most common consequences, leading to decreased cognitive performance and ability to concentrate. This negatively affects productivity at work and school performance. In addition, excessive sleepiness increases the risk of accidents, both on the road and at work, endangering both the affected person and those around them.

Long-term consequences

Chronic lack of sleep has a profound impact on physical and mental health. People who suffer from sleep disorders are at increased risk of developing cardiovascular diseases such as hypertension and myocardial infarction. There is also a strong link between sleep disorders and the development of type 2 diabetes due to hormonal and metabolic disturbances. Mentally, lack of sleep contributes to depression, anxiety and other mental disorders, seriously affecting the quality of life and general well-being.

How do we treat insomnia and sleep disorders?

Sleep disorders have remedies, depending on their causes.

• Adjuvants such as melatonin: Melatonin is particularly indicated for patients who have difficulty falling asleep but can maintain uninterrupted sleep once they have fallen asleep.
• Chronic insomnia related to health problems: In these cases, the treatment is recommended by the specialist depending on the existing condition, such as allergies, asthma or obstructive sleep apnea, and is aimed directly at the management of this condition.
• Chronic insomnia without other medical conditions: For these patients, a complex medical consultation is recommended. The American Academy of Sleep Medicine suggests a thorough physical exam to rule out other conditions, including a history that includes the patient's medical and psychiatric history. Treatment for chronic insomnia may include medication, cognitive-behavioral therapy, or a combination of these.
• Medicines: Sleeping pills, antidepressants and antihistamines are administered only on the doctor's recommendation.
• Relaxation techniques: Meditation and other relaxation techniques can be effective in treating insomnia, especially if it is caused by stress, major changes or strong emotions.

Sleep medicine is a medical subspecialty that has seen increased interest in recent decades as more and more people around the world experience difficulty falling asleep and staying asleep.

Research in this area investigates the effects of restless sleep at the cellular and subcellular level, as well as the impact of sleep deprivation on the body, including metabolism, gene expression, and hormonal dysregulation.

Insomnia and sleep disorders are medical conditions that require proper diagnosis and treatment to prevent other health problems and maintain a good quality of life.
