Non-epileptic paroxysmal dyskinesias present with different forms of extrapyramidal hyperkinesias (dystonia, chorea, athetosis, ballism) in variable combinations and with cerebellar signs, respectively. They may be classified as: 1. paroxysmal dystonias/choreoathetoses (paroxysmal dystonic choreoathetosis = PDC), paroxysmal kinesigenic choreoathetosis = PKC, intermediate form) and 2. paroxysmal ataxias (PA) (PA with myokymia and neuromyotonia, azetazolamide-responsive PA). Nocturnal paroxysmal dystonia is now regarded as one form of nocturnal frontal lobe epilepsy. Research in molecular genetics has substantially contributed to the etiologic understanding of paroxysmal dyskinesias: In different families linkage has been successfully completed for PDC (chromosome 2q) and PA (chromosomes 12p, 19p). PA are now identified as channelopathies with mutations in the potassium channel (PA with myokymia and neuromyotonia) and the calcium channel gene (azetazolamide-responsive PA).
To clarify the predictive value of the seven more commonly used postural reactions (PR) in the 1st year of life regarding the diagnosis of cerebral palsy (CP), we prospectively examined 204 high-risk infants of whom 58 developed CP, 22 had developmental retardation (DR) and 124 were normal at follow-up at 3 years of age. Abnormalities of five or more PR from the 1st month of life were correlated with spastic CP, while five or six abnormal PR were also correlated with athetoid CP. Three or less abnormal PR correlated with a normal outcome. All seven PR tested were significantly abnormal in children with spastic CP from the 1st month compared to normal children. Athetoid children demonstrated abnormalities of the Peiper-Isbert (P-I) reaction and Vojta reaction from the 1st month and of the vertical, horizontal and Collis vertical suspension from the 3rd month. Children with DR had significantly abnormal Collis horizontal and Collis vertical suspension, Vojta reaction and traction response from the 1st month and Peiper-Isbert reaction from the 3rd month. Ataxic children demonstrated significantly abnormal traction response from the 1st month, Collis horizontal reaction from the 7th month and Peiper-Isbert reaction from the 11th month. We conclude that the examination of PR is a useful quantitative and qualitative diagnostic screening tool for high-risk infants from the 1st month of life.
