Alternating hemiplegia of childhood is a rare syndrome characterized by infantile onset of episodic hemi-or quadriplegia. Most cases are accompanied by dystonic posturing, choreoathetoid movements, abnormal ocular movements, developmental delay, and progressive cognitive impairment - several cases reported, not progressive. Cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss (CAPOS) is an autosomal dominant neurologic disorder characterized by early-childhood onset of recurrent episodes of acute ataxic encephalopathy associated with febrile illnesses. Dystonia-12, also known as rapid-onset dystonia-parkinsonism, is an autosomal dominant disorder characterized by abrupt onset of asymmetric dystonia and parkinsonism in young adulthood, often after a trigger such as physical overexertion, trauma, heat, or fever. Affected individuals also show slowly progressive nonparoxysmal neurologic deterioration in a rostrocaudal gradient with prominent bulbar dysfunction - several cases. Green for dystonia only.Created: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
