Sleep Paralysis

Sleep Paralysis



Overview

Sleep paralysis is when you can’t move any part of your body right before falling asleep or as you wake up. It happens when your body is in between stages of sleep and wakefulness. An episode is temporary and only lasts for a few seconds to a couple of minutes. It’s a type of parasomnia.

You’ll likely feel scared or anxious during a sleep paralysis episode. When it ends, you may feel confused because you’ll regain movement of your body as if nothing happened.

Even one sleep paralysis episode can make you nervous about going to sleep. This can affect how you feel and function during the daytime.

There’s no treatment available to stop a sleep paralysis episode when you’re in the middle of one, but treatment is available to reduce how often episodes affect you.

Symptoms

You may experience the following symptoms during a sleep paralysis episode either right before falling asleep or as you’re waking up:

You can’t move your arms or legs.

You can’t speak.

Sensations of pressure against your chest (suffocation) or moving out of your own body.

Hallucinations (like there’s a dangerous person in your room).

Daytime sleepiness.

What does sleep paralysis feel like?

During a sleep paralysis episode, you’re aware of your surroundings but can’t move or speak. You can still move your eyes and breathe. You may feel:

Fear.

Panic.

Helplessness.

How long does sleep paralysis last?

The length of time you’ll experience a sleep paralysis episode varies. It could only last for a few seconds or up to 20 minutes. It usually only lasts a couple of minutes.

What happens if you wake someone up during sleep paralysis?

You can safely wake someone up during a sleep paralysis episode. The person having an episode may wake up fully and regain movement when you touch or talk to them. Someone in a sleep paralysis episode won’t be able to tell you what they feel or indicate with movement that they’re having an episode until they’ve recovered from one.

What causes sleep paralysis?

The exact cause of sleep paralysis is unknown. Healthcare providers notice they could happen with the following:

Narcolepsy.

Not sleeping enough (sleep deprivation).

An irregular sleep schedule (shift work sleep disorder).

Obstructive sleep apnea.

Mental health conditions like anxiety, bipolar disorder, post-traumatic stress disorder (PTSD) or panic disorder.

Certain medications (like ones that treat ADHD).

Substance use disorder (SUD).

Why does sleep paralysis happen?

Sleep paralysis happens when you regain awareness going into or coming out of rapid eye movement (REM) sleep. Your body hasn’t fully switched sleep phases or woken up during sleep paralysis.

When you’re sleeping, your brain sends signals that relax the muscles in your arms and legs. The result — muscle atonia — helps you remain still during REM sleep. As you’re in the REM sleep stage, you’ll likely have dreams. Your brain prevents the muscles in your limbs from moving to protect yourself from acting dreams out and causing injury.

What are the risk factors for sleep paralysis?

Sleep paralysis can happen to anyone at any age. It’s more common among people who have a varying sleep schedule (like with shift work). Symptoms may first appear in childhood or adolescence. Episodes are more frequent in your 20s and 30s.

Diagnosis 

Healthcare providers confirm or rule out sleep paralysis after a physical exam and a sleep evaluation. Your provider may ask you about:

Your symptoms, such as how often you experience sleep paralysis, what it feels like and when it started.

The quantity and quality of sleep you get, such as how many hours you sleep at night and whether you feel tired during the day.

Your medical history, including what medications you currently take and whether you smoke, use alcohol or unprescribed drugs.

Your mental health, like if you experience stress or have an underlying mental health condition like anxiety or depression.

Your family history and if you’re aware of any biological family members who experience sleep paralysis.

What tests diagnose sleep paralysis?

Your healthcare provider may recommend testing if they suspect a sleep disorder that causes sleep paralysis like narcolepsy. You may need:

An overnight sleep study (polysomnogram): The test monitors your breathing, heartbeat and brain activity while sleeping. It may enable healthcare providers to observe an episode of sleep paralysis or detect issues like sleep apnea.

Multiple sleep latency test (MSLT): This test measures how quickly you fall asleep and what kind of sleep you experience during a nap. The test helps uncover issues such as narcolepsy.

Treatment

Your treatment will depend on the reason why you have sleep paralysis. Your provider may recommend the following:

Taking medications that prevent you from reaching the REM stage of sleep.

Taking medications to treat an underlying mental health condition or sleep disorder (like antidepressants, for example).

Improving your sleep hygiene (habits that help you sleep better).

Talking to a mental health provider if you experience frequent stress.

How to stop sleep paralysis in the moment?

There’s no way to stop a sleep paralysis episode as it happens. You may notice that you come out of an episode sooner if you focus on making small body movements, like moving one finger, followed by moving two fingers, etc.

Type of Doctor Department :  Sleep specialist, neurologist, or a pulmonologist

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

HMSN Type I

 HMSN Type I Overview Hereditary motor and sensory neuropathy type 1 (HMSN I), also known as Charcot-Marie-Tooth disease type 1 (CMT1), is a group of inherited neurological disorders affecting the peripheral nerves. It is characterized by progressive muscle weakness and wasting, primarily in the feet and legs, as well as sensory loss. HMSN I is the most common form of HMSN and is typically caused by a duplication on chromosome 17p11.2-p12, including the PMP22 gene.  Symptoms Numbness and tingling: Often starting in the feet and potentially extending to the hands, these sensations can mimic poor circulation.  Reduced ability to feel pain and temperature: This can lead to unnoticed injuries and complications.  Motor Symptoms: Muscle weakness and wasting: Primarily affecting the distal muscles (those farthest from the body's core), such as the feet and hands.  Foot deformities: High arches (pes cavus) and hammer toes are frequently observed.  Gait abnormalit...

LEPR Deficiency

LEPR Deficiency Overview LEPR deficiency is a rare, inherited condition that affects how the body processes energy, responds to food and stores fat. Most people with this condition are obese before one year of age. Other symptoms include constant hunger and abnormal behaviors related to food. People affected with LEPR deficiency have low levels of sex hormones (hypogonadotropic hypogonadism) resulting in late or absent puberty and infertility. LEPR deficiency is caused by changes (mutations or variants) in the LEPR gene, which is responsible for making the receptor that interacts with a protein called leptin. Leptin is important for regulating appetite and growth of body fat. This condition is inherited in an autosomal recessive pattern. Diagnosis is based on a clinical examination, symptoms and the results of genetic testing. Diet, behavior modification, exercise programs and bariatric surgery have been used to help manage the symptoms of LEPR deficiency. Treatment is available for th...
