Is Pallido‐Pyramidal Syndrome Still a Useful Concept? No.

Clinico-radiological correlation studies of patients with pallidal lesions have shown that there are 2 major associated syndromes: dystonia and parkinsonism. Hemidystonia and generalized dystonia can develop after contralateral or bilateral lesions of the globus pallidus, respectively.[6] According to Davison's clinical description, only 1 of the patients had abnormal postures suggestive of lower limb dystonia. Davison's observation of a distinct syndrome of parkinsonism and pyramidal impairment, however, remains clinically useful despite being inaccurately named and should be revised simply to the concept and terminology of parkinsonism-pyramidal syndromes. Where dystonia, with or without parkinsonism, is the dominant movement disorder occurring with pyramidal signs, the syndromic term dystonia with spasticity (with or without parkinsonism) has previously been suggested,[1] although to align the two, dystonia-pyramidal syndrome could easily be substituted.
