Periodic Limb Movement Disorder
Periodic Limb Movement Disorder (PLMD) is a sleep condition distinguished by repeated twitching or jerking movements of the legs and feet during sleep. It can occur every 5 to 90 seconds for minutes to hours. PLMD and migraine share comorbidities such as restless leg syndrome and insomnia.
A study that looked at PLMD and migraine in children suggested that PLMD could influence migraine, increasing its severity, frequency and all disabling aspects and also treatment efficacy.1
