Kicking And Punching: The Violent No Rem Sleep Disorder

Kicking and punching during sleep can be caused by a rare sleep disorder called REM sleep behaviour disorder (RBD). During the REM stage of sleep, the body usually experiences temporary paralysis, but for people with RBD, this doesn't happen, and they physically act out their dreams. This can include anything from small muscle twitches to jumping out of bed, and it can result in injuries to themselves or their bed partner. RBD is also associated with neurodegenerative diseases, with many people who have it going on to develop Parkinson's disease or dementia years later.

REM sleep behaviour disorder (RBD) causes people to kick and punch during sleep

REM sleep behaviour disorder (RBD) is a rare parasomnia that causes people to physically act out their dreams during the rapid eye movement (REM) stage of sleep. While in the REM stage, the body typically experiences temporary paralysis, known as atonia, while the brain remains active. However, for those with RBD, this paralysis does not occur, allowing them to act out their dreams through movements such as kicking and punching.

The main symptom of RBD is the physical acting out of dreams, which can range from small muscle twitches and whispering to more violent actions such as punching, kicking, shouting, and jumping out of bed. These actions can result in injuries to the person with RBD or their bed partner. People with RBD often experience vivid and unpleasant dreams, such as arguments, accidents, or attacks, and may make noises like talking, laughing, or yelling during sleep.

RBD affects approximately 0.5% of the general population, with a higher prevalence in men over 50 years old. It is often associated with other neurological conditions, such as Parkinson's disease, Lewy body dementia, and multiple system atrophy. In some cases, RBD may be an early sign of these neurodegenerative disorders.

The exact cause of RBD is unknown, but it is believed to be related to a problem with certain nerve pathways in the brain. Risk factors for developing RBD include male gender, older age, neurological disorders, use of certain medications or substances, and environmental factors such as smoking, head injury, and pesticide exposure.

Diagnosis of RBD is typically made through a sleep study or polysomnogram, which monitors breathing, eye movements, body movements, and brain and heart activity during sleep. Treatment options include lifestyle changes, medication such as clonazepam or melatonin, and creating a safe sleep environment to prevent injuries.

RBD affects around 0.5% of the population

REM sleep behaviour disorder (RBD) is a rare parasomnia, affecting around 0.5% of the general population. However, the prevalence is higher in people with certain neurocognitive disorders, such as Parkinson's disease or dementia, and in those with narcolepsy.

RBD is characterised by vivid dreams and dream enactment behaviour, such as kicking, shouting, and punching. During the REM stage of sleep, the body usually experiences temporary muscle paralysis, known as atonia. However, for people with RBD, this paralysis doesn't occur, resulting in physical acting out of dreams. This can range from small movements, like whispering or twitching, to more violent actions, like punching, kicking, shouting, and jumping out of bed. These actions can cause harm to the person with RBD or their bed partner.

The exact cause of RBD is unknown, but it appears to be related to a problem with certain nerve pathways in the brain. Certain factors increase the likelihood of developing RBD, including being male, over 50 years old, having a neurological disorder, using antidepressants, or using or withdrawing from drugs or alcohol.

Diagnosis of RBD is typically made through a combination of patient history, sleep studies, and polysomnography, which involves monitoring breathing, eye movements, body movements, and brain and heart activity during sleep. Treatment options include lifestyle changes, medication, and creating a safe sleeping environment to prevent harm. While there is no cure for RBD, management strategies can help control symptoms and improve quality of life for those affected.

It is more common in men over 50

REM sleep behaviour disorder (RBD) is a sleep disorder that predominantly affects men over 50. During the REM stage of sleep, the body typically experiences temporary paralysis, but for people with RBD, this doesn't happen, and they end up physically acting out their dreams. This can include kicking, punching, shouting, and jumping out of bed.

Men over 50 are nine times more likely to have RBD than women of the same age group, and the average age of onset is 61 years. It is more common in men over 50 because of the strong association with certain neurological disorders, such as Parkinson's disease, Lewy body dementia, and multiple system atrophy. These disorders are also called alpha-synucleinopathies and are characterised by the deposition of alpha-synuclein protein in the brain.

RBD is often an early warning sign of these neurological conditions, with studies finding that a large percentage of men over 50 with RBD eventually develop one of these disorders within a few years of their RBD diagnosis. For example, one study found that 38% of men aged 50 or older with RBD developed Parkinson's disease, Lewy body dementia, or multiple system atrophy within 13 years. Another study found that 81% of men with RBD developed one of these disorders within 16 years.

The link between RBD and these neurological disorders is still being researched, but it is thought that RBD may be caused by a problem in the brainstem, specifically the pons region, which is often affected in Parkinson's disease, Lewy body dementia, and multiple system atrophy. Additionally, certain medications, such as antidepressants, can increase the risk of developing RBD.

Due to the violent nature of the movements during RBD episodes, there is a high risk of injury to the person or their bed partner. Therefore, it is important to create a safe sleeping environment and seek treatment to reduce the risk of harm. Treatment options include lifestyle changes, such as avoiding triggers like alcohol, and medication such as clonazepam and melatonin.

People with RBD are often unaware of their nocturnal movements

People with REM sleep behaviour disorder (RBD) are often unaware of their nocturnal movements. They may find out about their condition from a bed partner or roommate who observes their kicking, punching, or flailing movements during sleep. The person with RBD may only become aware of their nocturnal behaviour if they sustain injuries such as bruises, cuts, or broken bones.

During the REM stage of sleep, the body typically experiences temporary paralysis of most skeletal muscles, allowing us to dream quietly and safely. However, in people with RBD, this muscle paralysis does not occur, enabling them to physically act out their dreams. This can range from small muscle twitches and whispering to more violent movements like punching, kicking, shouting, and jumping out of bed.

The dreams associated with RBD are often intense, unpleasant, and violent, such as being chased or attacked. The person may unknowingly act out these dreams in real life, potentially causing harm to themselves or their bed partner. Episodes of RBD can occur once or multiple times during the night and can develop suddenly or gradually. They usually worsen over time and are more likely to occur in the second half of the night when REM sleep stages are longer.

While most people with RBD are unaware of their nocturnal movements, some may present to their doctor reporting frequent vivid dreams, unexplained injuries, or falling out of bed. However, RBD is often under-recognised and challenging to distinguish from other sleep disorders with similar symptoms.

If you or someone you know exhibits signs of RBD, it is important to consult a healthcare professional for a proper diagnosis and treatment plan.

RBD can be treated with medication and lifestyle changes

REM sleep behaviour disorder (RBD) is a parasomnia that causes people to physically act out their dreams while in the rapid eye movement (REM) stage of sleep. While there is no cure for RBD, it can be treated with medication and lifestyle changes.

Lifestyle Changes

Lifestyle changes can help to treat RBD and include:

• Avoiding triggers such as alcohol and certain antidepressants.
• Practising good sleep hygiene, such as following a consistent sleep schedule, eliminating outside noise, and sleeping in a cool, dark room.
• Safeguarding the bedroom by removing sharp objects and weapons, placing padding on the floor, installing padded bed rails, and moving furniture and other trip hazards away from the bed.

Medication

Medications that can be used to treat RBD include:

• Clonazepam: a prescription medication usually used to treat anxiety that can help suppress muscle activity during REM sleep. However, it can cause side effects such as daytime sleepiness, loss of balance, and worsening of sleep apnea.
• Melatonin: a supplement that can help regulate the sleep cycle and has been found to be effective in treating RBD with fewer side effects than clonazepam.
• Pramipexole: a dopamine agonist primarily prescribed to treat Parkinson's disease and restless leg syndrome, but recent research shows that it can help treat RBD symptoms.
