Periodic Limb Movement Disorder (PLMD)

Periodic Limb Movement Disorder (PLMD) Periodic limb movement disorder (PLMD) is a sleep disorder that causes patients to move rhythmically in the limbs (typically the legs, although upper limb movements may occur) during sleep. Unlike normal spasms, period limb movements can fluctuate in severity, can last from a few minutes to several hours, and tend to cluster in episodes. Patients suffering from PLMD are usually unaware of these movements. PLMD Causes While the causes are not certain, research shows that periodic limb movement disorder may occur in people who are on medications (most notably, antidepressants), and in people with a variety of medical problems including Parkinson’s disease and narcolepsy. Almost all people with restless legs syndrome suffer from PLMD. Periodic Limb Movement Disorder Symptoms Some of the most common periodic limb movement disorder symptoms include: Fragmented sleep caused by partial or full brief awakening Leg movements involving the extension of the big toe and flexing of the hip, ankle, or knee Movements (mostly in the legs) occur at regular intervals during the night Poor quality and non-refreshing sleep Periodic Limb Movement Disorder Treatment While there is no cure for PLMD, various periodic limb movement disorder treatment methods are available, which can significantly reduce or eliminate the symptoms of the disorder. For continued relief from the symptoms of PLMD, medical doctors may prescribe one of several classes of drugs including: Medication for Parkinson’s disease Anticonvulsant medications Narcotics Benzodiazepines People with PLMD should also avoid the caffeine found in chocolate, coffee, tea and soft drinks as it can intensify common symptoms. Moreover, antidepressants may worsen the symptoms of PLMD.
