[Diagnosis and therapy of restless legs syndrome in the doctor's office].
BACKGROUND
Restless legs syndrome (RLS) is a movement and sleep disorder with leg dysesthesias with a high prevalence (9-18% in Austria).


OBJECTIVE
Determination of frequency, diagnosis and therapy of RLS in general practitioner and specialist offices.


METHODS
Telephone survey of a random sample of 120 general practitioners, 100 neurologists and 80 specialists in internal medicine.


RESULTS
69% of the whole sample of doctors reported seeing 1 to 10 RLS patients, but in proportion to the prevalence of these two conditions fewer cases of RLS than of Parkinson's disease are treated. In all three groups of doctors, 84% consider the 4 key symptoms (urge to move the legs accompanied or caused by dysesthesia; worsening of symptoms at rest or inactivity; relief by activity; worsening of symptoms in the evening/at night) the most important diagnostic criteria for RLS, followed by a complaint of disturbed sleep (75%), daytime tiredness (43%) and dopaminergic responsiveness in a therapeutic trial (29%). 83% of general practitioners and 86% of medical specialists refer their RLS patients to a neurologist, 19% to a polysomnographic examination. 75% of doctors decide for pharmacological treatment of RLS, 18% for psychotherapy, 15% for household remedies. 54% of all doctors (70% of the neurologists, 68% of the GPs, 48% of the medical specialists) prescribe dopamine agonists. L-Dopa is used by 49% (61% of the neurologists, 42% of the GPs, 44% of the medical specialists). 17% prescribe GABAergic drugs, 6% opiates. 51% would be highly interested in obtaining a drug specifically registered for the treatment of RLS.


CONCLUSIONS
RLS is not as well known as Parkinson's disease. Thus providing doctors with relevant information and further education programs on this subject seems desirable. In Austrian doctors' offices the diagnosis of RLS is usually obtained clinically on the basis of the 4 key symptoms. Patients suffering from insomnia of multifactorial pathogenesis should be referred to an outpatient clinic for sleep disorders with an associated sleep laboratory. Especially neurologists and GPs consider dopamine agonists the treatment of first choice, closely followed by L-Dopa.
