Restless Leg Syndrome
(Neurological Disorder)
In this condition factsheet:
Diagnosing Restless Leg Syndrome
There are no lab tests to diagnose RLS. However, your doctor may order a series of tests to identify if you have any other disorders that may be causing your symptoms, such as a vitamin deficiency.
The diagnosis of RLS requires an assessment of your medical history and description of symptoms. The doctor will rule out other possibilities and focus on the presence of four factors in order to diagnose your condition:
- an overwhelming need to move the arms or legs in order to relieve abnormal sensations such as crawling, tingling, burning or pain.
- symptoms that are temporarily relieved by movement.
- symptoms that are worse or only present during periods of rest such as at rest or while sitting.
- symptoms that get worse in the evening or at night.
Occasionally, the doctor may ask you to undergo an overnight sleep test in a sleep clinic to determine the cause of sleep disturbance more conclusively.
In addition to a thorough questionnaire, your physician will do a complete physical exam, a complete blood count, iron levels and ferritin levels. If low levels of iron are found, your physician will investigate if there is a possible reason for this by ordering a colonoscopy or other tests.
Treating and Preventing Restless Leg Syndrome
Treatment for RLS focuses on controlling any underlying health condition that may be causing RLS (e.g., correcting a lack of iron). If iron is administered, it may be given with vitamin C, and levels will be checked regularly.
The doctor will first suggest non-medication measures to manage mild symptoms. For example, some people find that light exercise such as walking or stretching, taking a bath, massaging the leg, applying hot or cold packs, and practicing relaxation techniques such as meditation or yoga reduces the symptoms. Changing your sleep schedule to allow more time for sleeping in may also help. The doctor may suggest you keep your mind active (e.g., by reading) during periods of prolonged inactivity, such as travelling, in order to take your mind off RLS symptoms.
However, if your symptoms are frequent and severe or if you are having difficulty falling or staying asleep, the doctor may prescribe medications for you. To control daily symptoms, medications that are used for Parkinson's disease such as ropinirole, rotigotine and pramipexole are frequently prescribed. Levodopa/carbidopa is effective for intermittent symptoms and as prevention just before a long car ride or travelling on a plane. The medications have side effects and sometimes need to be weaned off for a period before being started again.
Antiseizure medications (such as gabapentin and pregabalin), benzodiazepines (such as clonazepam and zolpidem), or opioids (such as codeine) can give some relief.
Since the cause of RLS is not well understood, there are no known ways to prevent it. However, people who have RLS may be able to decrease episodes by making simple lifestyle changes including eliminating caffeine, nicotine, and alcohol and by treating any underlying conditions.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
