Any medical condition that interferes with someone’s life in a substantial way, lessens their quality of life or causes distress for their loved ones is considered by medical professionals to be a medical disorder. Conditions that fit this bill while interfering with sleep are categorized as sleep disorders. Restless legs syndrome falls right behind insomnia as one of the leading medical conditions that interfere with sleep.
Information. Restless legs syndrome is a disorder of the nervous system that causes the sufferer’s legs to feel tingly and crawly. Relief only comes when the legs are moved, and that relief only lasts for seconds. RLS is considered a sleep disorder because the symptoms usually happen at night, and it can interfere with sleep. Up to 10 percent of Americans experience RLS regularly, and many more experience at least occasional symptoms. It can be so bad that sleep can be almost impossible. This can cause a reduction in quality of life and trouble at work and school.
