Dear Taku, Welcome to HealthcareMagic,
Restless leg syndrome
(RLS) is currently considered a neurologic movement disorder
of the limbs
, often associated with a sleep complaint. Once correctly diagnosed, RLS can usually be treated effectively and in some secondary cases, it can even be cured. Though exact pathogenesis is unclear, the most widely accepted mechanism involves a genetic component along with abnormalities in the central, subcortical dopamine
pathways in brain. A number of drugs are used for treatment depending on symptoms.
