dyskinetic cerebral palsy
A subtype of cerebral palsy characterized by involuntary, uncontrolled movements that can be slow and writhing or quick and jerky.
Full Definition
Dyskinetic cerebral palsy, also known as extrapyramidal cerebral palsy, results from damage to the basal ganglia and typically accounts for 10-20% of cerebral palsy cases. The condition is characterized by involuntary movements that interfere with voluntary motor control. Two main subtypes exist: dystonic (slow, twisting movements) and choreoathetoid (rapid, irregular movements). Children with dyskinetic CP often have fluctuating muscle tone and may experience difficulty with speech, feeding, and purposeful movement. Intelligence is often preserved, but communication challenges may mask cognitive abilities.
Usage
Usage note: Avoid the older term 'athetoid cerebral palsy' in favor of 'dyskinetic cerebral palsy' for current medical accuracy.
