Periodic Limb Movement Disorder is a sleep disorder in which the person involuntarily moves his limbs during sleep. The person does not realize that he or she is moving the limbs. Periodic Limb Movement Disorder is involuntary and the person is completely unaware of the movements. Symptoms are:
• Excessive tiredness during the day
• Falling asleep during the day
• Trouble falling asleep during the night
• Involuntary movement of limbs during first half of night
HOW IS PERIODIC LIMB MOVEMENT DISORDER DIAGNOSED?
The diagnosis is based on the clinical history as well as an overnight polysomnogram (PSG). This is a test that records sleep and the bioelectrical signals coming from the body during sleep. A thorough neurological examination should be performed. Respiratory monitoring during the PSG allows one to rule out the presence of sleep disordered breathing as a cause for the disrupted sleep and excessive muscle activity. Occasionally, additional sleep laboratory testing is useful. Blood work may be ordered to check on iron, folic acid, vitamin B12, thyroid function, and magnesium levels.
HOW IS PERIODIC LIMB MOVEMENT DISORDER TREATED?
Anticonvulsants are usually prescribed for treating Periodic Limb Movement Disorder. Anti depressants and caffeine consumption must be avoided.
