Dopa Responsive Headache: Restless Head Syndrome or a Cephalic Variant of Restless Legs Syndrome?

Abstract

Restless legs syndrome (RLS) is a common but highly undiagnosed sensorimotor disorder. It typically affects the lower extremities. However, various other parts of the body can be involved, such as the arms, the abdomen, the face, the oral cavity, head‑neck, and the genital area. In addition, RLS is linked with a large number of comorbid conditions, including various headache disorders. Herein we are reporting two cases of RLS who also had headaches. The headaches fulfilled the criteria of chronic tension‑type headache (CTTH). The administration of levodopa provided improvement in both RLS and CTTH. We suggest that that headache in a subset of patients with RLS may be the part of RLS symptoms complex.
