Abstract
Amyotrophic lateral sclerosis and Parkinsonism‐dementia complex of the Kii peninsula (Kii ALS/PDC) is an endemic and a tauopathy, which shows clinical symptoms of amyotrophy, parkinsonism, and dementia. The objective of this study was to report the role of oxidative stress on Kii ALS/PDC using biochemical analysis. Urinary 8‐hydroxydeoxyguanosine (8‐OHdG)/creatinine ratio was analyzed in 11 patients with Kii ALS/PDC and 8 normal controls. The mean level of urinary 8‐OHdG/creatinine ratio of the patients with Kii ALS/PDC was significantly higher than that of control subjects. Oxidative stress may be implicated in pathogenesis of Kii ALS/PDC. © 2008 Movement Disorder Society

## Abstract Amyotrophic lateral sclerosis‐parkinsonism dementia complex (ALS/PDC) is a distinct neurodegenerative disorder characterized by ALS pathology with neurofibrillary tangles (NFTs) in the spinal cord and brain. Recent clinical studies have revealed a high incidence and a high familial occu
An update of the endemic parkinsonism-dementia complex (PDC) frequently associated with amyotrophic lateral sclerosis (ALS) in the high prevalence ALS focus of the Kii peninsula of Japan is presented. The initial symptom was parkinsonian gait or hypobulia/amnesia, which was followed by akinesia, rig
