A large majority of patients (85%) with RLS report difficulty falling asleep at night as a consequence of the condition, and they may experience excessive daytime somnolence because of poor sleep quality resulting from multiple PLMS-induced arousals. PLMS noted on polysomnography (PSG) alone do not warrant treatment. Clinicians should consider treating PLMS if they are causing frequent arousals.
