Approximately 5% to 15% of adults are affected by symptoms
of
restless legs syndrome.1 The
condition may also occur in children, although the symptoms may not be
recognized. Most people diagnosed with restless legs syndrome are middle-aged
and older.
Episodes usually occur sporadically in early
adulthood, gradually increasing in frequency. After age 50, many people with
this condition have daily occurrences.2
Some estimates suggest that restless legs syndrome affects twice as many
women as men. Approximately 10% to 20% of women develop it during
pregnancy,3 although it usually goes away without
treatment soon after the baby is born.
