title: Pallido-nigro-luysian atrophy, progressive supranuclear palsy and adult onset Hallervorden-Spatz disease: a case of akinesia as a predominant feature of parkinsonism.
abstract: Few parkinsonian patients present with 'pure akinesia' or with severe akinesia accompanied by only mild rigidity, tremor and other manifestations such as ophthalmoplegia. Pathological examinations of such cases have rarely been conducted and have revealed findings compatible with progressive supranuclear palsy (PSP), pallido-nigro-luysian atrophy (PNLA) or Parkinson's disease. We report a parkinsonian patient whose main clinical feature was akinesia. A postmortem study of this patient showed findings corresponding to PNLA and PSP. Histochemical properties of the pallidal pigment granules were equivalent to those of Hallervorden-Spatz disease (HSD) and striatonigral degeneration. In addition to iron-positive pigment granules, spheroids, severe neuronal loss and gliosis in the globus pallidus and substantia nigra, formation of Alzheimer's neurofibrillary tangle (NFT) in the brainstem shares characteristics with PSP, adult onset HSD and PNLA. We suggest that the underlying pathology of 'pure' akinesia is most often situated in the globus pallidus substantia nigra and subthalamus (Luys), and that PSP, PNLA and adult onset HSD may constitute a spectrum of one disease.
