Restless Leg Syndrome is a neurological disorder characterized by an irresistible urge to move one's body during sleep to stop uncomfortable or odd sensations. Although sensations also occur during the day, Restless Leg Syndrome is considered a sleep disorder because symptoms are especially severe at night when one is lying down, leading to sleep deprivation.
Symptoms include the urge to move one’s limbs with or without strange sensations, motor restlessness, and sensations increasing with relaxation and worsening in
the nighttime.
Diagnosis of Restless Leg Syndrome is complicated and may require blood tests and other exams to rule out other conditions.
