A 75-year-old man developed l-dopa non-responsive parkinsonism, supranuclear ophthalmoplegia, neck dorsiflexion, and dementia. Atrophy of the midbrain tegmentum on MRI and normal myocardial uptake of MIBG led to the clinical diagnosis of progressive supranuclear palsy (PSP). Autopsy revealed depigmentation of the substantia nigra and locus ceruleus. Alzheimer's disease pathology was advanced with PSP-like neurofibrillary tangles distribution, and Lewy bodies were abundant in limbic lobe, while scarce in lower brainstem nuclei. Tuft-shaped astrocytes were not apparent. Although decreased myocardial uptake of MIBG is a rule in patients harboring Lewy bodies, its normal uptake may be related to their absence in lower brainstem nuclei.

An 85-year-old man developed l-dopa responsive parkinsonism indistinguishable from Parkinson's disease and subsequent dementia, followed by supranuclear ophthalmoplegia and neck dorsiflexion at the terminal stage. Midbrain tegmentum and medial temporal lobe were atrophic on magnetic resonance imaging, while decreased blood flow was predominant in frontotemporal lobes, detected by 3D-SSP of 123I- IMP SPECT. Alzheimer-type pathology without Lewy body pathology was confirmed at autopsy. Substantia nigra showed mild degeneration and several neurofibrillary tangles without Lewy body pathology or progressive supranuclear palsy cytopathology. L-dopa responsive parkinsonism could be an initial manifestation of Alzheimer's disease, which should be included in the differential diagnosis.

Mitochondrial dysfunction underlies several human chronic pathologies, including cardiovascular disorders, cancers and neurodegenerative diseases. Impaired mitochondrial function associated with oxidative stress can be a result of both nuclear and mitochondrial DNA (mtDNA) mutations. Neurological disorders associated with mtDNA mutations include mitochondrial encephalomyopathy, chronic progressive external ophthalmoplegia, neurogenic weakness, and Leigh syndrome. Moreover, mtDNA mutations were shown to play a role in the development of Parkinson and Alzheimer's diseases. In this review, current knowledge on the distribution and possible roles of mtDNA mutations in the onset and development of various neurodegenerative diseases, with special focus on Parkinson's and Alzheimer's diseases has been discussed.
