Restless Legs Syndrome (RLS) is a neurological disorder characterised by an irresistible urge to move the legs, often accompanied by uncomfortable sensations like tingling, itching, or crawling. Symptoms worsen during periods of inactivity, particularly in the evening and at night, leading to sleep disturbances and difficulty falling asleep. This is experienced during wakefulness.
Periodic Limb Movements of Sleep (PLMS), on the other hand, are repetitive and involuntary limb movements during sleep, typically involving the legs. These movements can disrupt sleep and lead to daytime fatigue. PLMS often co-occurs with RLS but can also occur independently. Both conditions can contribute to poor sleep quality and affect overall well-being, requiring medical evaluation and management.
