Insomnia and Sleep apnea may be two of the most common sleep disorders, but they are surely not the only two on the list. Most of the following sleep disorders are rare, but are possible for people of various ages to get.
Please be aware that not all sleep disorders in existence are on this list.
Narcolepsy is characterized by sudden attacks of sleep. Common symptoms can include issues with the muscles (loss of muscle control or muscle weakness),hallucinations, and daytime sleepiness. Treatment for this can include a form of therapy (such as a support group), a stimulant (such as Modafinil that can treat Narcolepsy and sleep apnea), or an antidepressant (such as protriptyline).
This is a condition characterized by an urge to move the legs (typically in the evenings). The common symptoms can include sleep disturbances and and difficulty falling/staying asleep. The body can experience fatigue/ restlessness. Self care, such as physical exercise or relaxation techniques (meditation, yoga, etc.) can help. A massage can relax tense muscles as well. Nerve pain medication (such as pregabalin) can block pain that's caused by damaged nerves.
Imagine sleeping up to 23 hours a day...for three weeks in a row. It's nicknamed "Sleeping Beauty Syndrome", and it can affect males around the age of 15. Symptoms prevail for around 8 years (and longer in women. "Little is known as to the causes of the disorder although according to a study published in Brain there has been some link to it being preceded by an infection in more than 2/3 of patients. The only medication that has proven beneficial is the mood stabilizer lithium." -From Alaska Sleep Clinic
Having Sleep Paralysis means that you are aware of your surroundings, but you are unable to move or speak. You are more likely to get it as you age, and it's usually self diagnosable. Episodes include inability to speak or move while falling asleep or upon waking. This usually lasts one or two minutes. good sleep habits (such as a regular bedtime schedule and avoiding naps) can help along with specialists such as Psychiatrists that treat mental disorders with medications and Clinical psychologists that help cure mental disorders through talking.
"In a person with REM sleep behavior disorder (RBD), the paralysis that normally occurs during REM sleep is incomplete or absent, allowing the person to "act out" his or her dreams. RBD is characterized by the acting out of dreams that are vivid, intense, and violent." - From WebMd
Those movements can lead to various injuries.
Fatal familial insomnia begins with trouble getting to sleep one night and steadily increases until the sufferer is no longer able to sleep. Symptoms include: high blood pressure, rapid heart rate, excessive sweating, difficulty walking, and muscle twitches.
"Fatal Familial Insomnia is not currently treatable (although some of the symptoms may be treated) and is a very aggressive disorder. It can last from 6 months to 3 years with an almost inevitable progression towards coma and death with an average survival span of 18 months." -From Alaska Sleep Clinic
PLMD describes repetitive movements in the lower limbs during sleep. They occur on an average of every 20-40 seconds. those movements include brief muscle twitches, jerking movements, or flexing of the feet. It may occur with restless leg syndrome, but they're not the same thing. PLMD can be primary and secondary, the primary having no known cause, and the secondary caused by an underlying sleep disorder (sleep apnea, narcolepsy, etc.).
Every year, there are over 3 million cases of someone getting out of bed and performing tasks while asleep. It normally starts after one or two hours after starting to fall asleep. The victim may be unable to recall the time they started sleepwalking. It may also lead to daytime fatigue and falling. It currently isn't curable, but treatment can help. Establishing a sleep schedule and meditating are two of the best forms of self treatment.
