Answer

Patients with RLS and periodic leg movements of sleep (PLMS) may be at increased risk for hypertension. PLMS is associated with an autonomic surge and an increase in blood pressure. [21] Patients may also be more prone to headaches (migraine and tension-type). The headaches are probably secondary to disturbances in sleep associated with RLS and PLMS. Learning and memory difficulties have also been associated with RLS, presumably secondary to disrupted nocturnal sleep. [21]
