The symptoms may improve once the iron level or anemia is corrected. Decreasing caffeine consumption may improve symptoms. RLS occurs in both sexes. Symptoms can begin any time, but are usually more common and more severe among older people. There is no laboratory test that can make a diagnosis of RLS and, when someone with RLS goes to see a doctor, there is usually nothing abnormal the doctor can see or detect on examination.
Diagnosis therefore depends on what a person describes to the doctor.
The history usually includes a description of the typical leg sensations that lead to an urge to move the legs or walk. These sensations are noted to worsen when the legs are at rest, for example, when sitting or lying down and during the evening and night. The person with RLS may complain about trouble sleeping or daytime sleepiness. In some cases, the bed partner will complain about the person's leg movements and jerking during the night. To help make a diagnosis, the doctor may ask about all current and past medical problems, family history, and current medications.
