Other Types Of Sleep Disorder


If you live alone and it does not disturb your sleep, this may not be a major problem for you. But if it wakes you up, causing a bad sleep, or disturbs your sleep partner, then this is a more obvious problem.

Surveys have shown that partners of people who snore may suffer from poor health due to disturbed sleep. Sometimes it resorts to another common solution– like sleeping in a different room.

There is also evidence that snoring could get worse over time if it is not controlled. Prolonged snoring can damage the blood vessels of your muscles, which further reduces control and makes your snoring worse.


Allergies and respiratory problem

Allergies, upper respiratory infections or colds can make you difficult to breathe. The inability of breathing from your nose can also cause the sleep disorder.


Nocturia, or frequent urination, can disturb your sleep by making you wake up during the night. Hormonal imbalances and urinary tract diseases can contribute to the development of this disease. Make sure you call the doctor immediately if frequent urination is accompanied by bleeding or pain.

Chronic pain

Sometimes when you fall asleep and you wake up suddenly because of pain, or that pain does not let you sleep, then you are suffering from chronic pain.

  • Arthritis
  • Fibromyalgia
  • Persistent headaches
  • Continuous lower back pain
  • Inflammatory bowel disease


Stress and anxiety

Sometimes stress and tensions can lead to a negative impact on sleep quality and does not let you sleep properly.


REM sleep disorder

For most people, dreaming is purely a “mental” activity: Dreams occur in the mind while the body is at rest. But people who suffer from paradoxical sleep disorder (RBD) Act their dreams. They physically move members or even get up and engage in activities associated with waking up. Some fall asleep talking, shouting, screaming, patting or punching. Some even fly out of bed in sleep! The RBD is usually noticed when it presents a danger to the sleeping person, his or her bed partner or other people she meets. Sometimes, adverse effects such as injuries sustained by the partner or partner during their sleep trigger a diagnosis of RBD. The good news is that RBD can usually be treated successfully.


So, for most people, even when they have vivid dreams in which they imagine themselves to be active, their bodies are motionless. But people suffering from RBD do not have this muscular paralysis, which allows them to express dramatic and/or violent dreams during REM sleep. Sometimes they start by talking, twisting and jerking themselves during their dreams for years before fully realising their REM dreams.


Sleep talking

Sleep talking is a sleep disorder defined as a conversation during sleep without being aware of it. Sleeping can involve complicated dialogues or monologue, complete gibberish or mumbling. The good news is that for most people it is a rare and short-lived event. Anyone can experience talking sleep, but the condition is more common in males and children.

Sleeptalking are not generally aware of their behaviour or words; Therefore, their voices and the type of language they use may seem different from their awakened speech. Talking can be spontaneous or induced by a conversation with the sleeper.


Sleep walking

It is a behavioral disorder that occurs during deep sleep and leads to the walking or execution of other complex behaviours during sleep. It is much more common in children than adults and is more likely to occur if a person is deprived of sleep. Because a sleepwalker usually stays deeply asleep throughout the episode, it can be difficult to wake up and probably will not remember the sleepwalking incident.

Sleepwalking usually involves more than just walking during sleep; It is a series of complex behaviors that take place during sleep, the most obvious of which is walking. The symptoms of sleepwalking range from simply sitting in bed and looking around, walking in the room or home, leaving the house and even travelling long distances. It’s a common misconception that a sleepwalker shouldn’t be awake. In fact, it can be dangerous enough not to wake a sleepwalker.



Nightmares are dreams with vivid and disturbing content. They are more common in children during REM sleep, but they can also happen to adults. They usually involve an immediate awakening and a good reminder of the dream. Nocturnal terrors, also widespread in children, are often described as extreme nightmares that occur during non-REM sleep.

Nocturnal terrors have common characteristics. They usually include excitement, agitation, large pupils, perspiration and increased blood pressure. Usually the child cries out and seems terrified for several minutes until they end up relaxing and going back to sleep. Nocturnal terrors usually occur early in the night and may be associated with sleepwalking. The child usually does not remember or has only a vague memory of his dream.
