Paroxysmal kinesigenic dyskinesia (PKD)

This article was written by Dr. Aursulesei Ruxandra, pediatric neurologist specialist with extensive experience in diagnosing and treating neurological conditions. Pediatric neurology plays an important role in the periodic neurological evaluation of premature infants, as well as of all newborns at risk of developing neurological sequelae, with the goal of early detection and treatment of any impairment of the nervous system.

What is paroxysmal kinesigenic dystonia (PKD)?

Paroxysmal kinesigenic dystonia is a transient segmental alteration of muscle tone, triggered by certain stimuli.

Manifestations begin in childhood and occur frequently. They are precipitated by sudden movements and have an increased likelihood of occurring after rest. They occur more frequently in the legs than in the hands. They can be triggered by fright/surprise. Predisposing factors include anxiety and psychological tension. Slow initiation of movements seems to reduce or stop them.
