Good sleep is essential for a good life, and we spend about one-third of our lives sleeping. Therefore, it is essential to be aware of disorders that can occur during sleep, how to identify them, and treatments are available for them.
There are many types of sleep disorders but here are some of the most common ones:
Let’s take a deeper look into each of the above-mentioned sleep disorders including how each affects the patient and what they can do to prevent them.
People with insomnia find it very difficult to fall asleep and/or sleep well at night despite having a suitable environment and time to sleep. This will result in an impairment in their daytime functioning. In some people, this can be short-term, such as in anticipation of a stressful event like facing an exam or starting a new job. In others, this goes on for many months and years, causing distress to the patient.
Patients with insomnia will be evaluated using
This condition’s management includes sleep hygiene measures, medication revision and cognitive behavioural therapy.
These conditions are involved with abnormal and difficult respiration during sleep. While some of these sleep-related breathing disorders have low health impacts, others may have serious consequences due to their effects on the patient’s sleep and balance of oxygen and carbon dioxide in their blood.
There are a few types of sleep-related breathing disorders. They are
Some risk factors of obstructive sleep apnoea are
Sometimes a spouse may notice that the patient stops breathing at night for prolonged periods. This phenomenon is known as an apnoeic spell. Patients are evaluated with sleep studies called ‘polysomnography’, tests that evaluate sleep in detail and diagnose the underlying sleep disorder. The first line treatment is CPAP therapy (a device that provides continuous positive airway pressure). Additionally, weight loss with exercise and a healthy diet are also substantial.
These are a rare group of sleep disorders where patients complain that they are always sleepy during the day and the night. Patients tend to fall asleep in the daytime even after adequate sleep. E.g. Narcolepsy. Some patients with excessive sleepiness may have an underlying undetected medical or psychiatric condition.
Excessive sleep has a significant detrimental impact on the patient’s life. These patients must be evaluated with sleep studies and blood investigations before starting their treatment.
Circadian rhythm sleep-wake disorders are a group of disorders where the patient’s body’s clock, which helps to maintain a regular day and night pattern, is affected.
There are several types of circadian rhythm sleep-wake disorders.
This is where the patient does not fall asleep until the morning and tends to wake up in the afternoon – the patient’s circadian clock is delayed compared to the average population. These patients may struggle to wake up on time for school and work.
On the other hand, this disorder tends to have an early sleep pattern and early rise pattern. There are various types of disorders. Shift workers also suffer from the detrimental effects of not sleeping on time and staying awake when they should be sleeping.
This is another condition in which people suffer due to crossing time zones. Understanding these conditions is vital as many treatment modalities help reduce these problems.
Parasomnias are another set of sleep disorders involving a lot of sleep movement. In certain sleep stages, some people have confusional arousals, sleepwalking, sleep terrors, sleep-related eating, violent movements in sleep, acting out dreams, nightmares etc. Patients are evaluated with a sleep diary and polysomnography. These conditions must be identified and treated as many patients suffer from poor sleep and daytime dysfunction due to these issues.
Sleep-related movement disorders include restless leg syndrome and periodic limb movement disorder, where the patient has a lot of leg movement at night, leading to disturbed sleep.
The baseline management of any sleep disorder is the maintenance of good sleep hygiene practices.
Despite these measures, if a patient feels that they have an issue with their sleep, it is best not to delay diagnosis, as sleep is essential for a healthy life. They can consult experienced sleep specialists via the oDoc app to have a comfortable and convenient consultation in just three taps within the comfort of their own home.
