RLS can be difficult to diagnose in children, especially younger ones. [22] For a definite diagnosis, patients must endorse the diagnostic criteria and be able to describe leg symptoms in their own language. [23] Alternatively, they must have the diagnostic criteria plus sleep disturbances, a sibling or parent with RLS, and a PLMS index higher than 5 on PSG. [22] For a possible diagnosis, a PLMS index higher than 5 on PSG and a first-degree family member with RLS are required. These strict criteria are intended to prevent overdiagnosis of RLS in children.
