Toddler Restless Leg Syndrome

Restless leg syndrome (RLS) is a neurological disorder that causes uncomfortable feelings in the legs and a strong urge to move the legs to relieve discomfort. While it is most common in adults, restless leg syndrome can be diagnosed in toddlers as young as two, per the RLS Foundation.

Causes

• When toddlers develop restless leg syndrome, they have often inherited the condition. Other possible triggers include iron deficiency and underactivity of dopamine in the brain, according to the RLS Foundation.

Symptoms

• Symptoms include discomfort in the legs that is worse at rest and at least partially relieved my movement. Toddlers may describe the discomfort as a crawling or tickling feeling.

Effects

• Toddlers with restless leg syndrome may not sleep well. This can lead to irritability, fatigue, hyperactivity or fussiness.

Diagnosis

• When other medical tests are normal, a toddler may be diagnosed with RLS if he displays symptoms and can verbalize the discomfort, or if there is strong evidence to support a diagnosis.

Treatment

• Getting enough sleep may help toddlers with RLS. A doctor may recommend iron supplements if a child's iron levels are low, and medications can be prescribed to improve sleep or increase dopamine if necessary.
