Coexistence of Creutzfeldt-Jakob disease, Lewy body disease, and Alzheimer's disease pathology: an autopsy case showing typical clinical features of Creutzfeldt-Jakob disease.

We report here an autopsy case of sporadic Creutzfeldt-Jakob disease (CJD) without hereditary burden and with a clinical course typical of sporadic CJD. A 77-year old man developed memory disturbance, followed by gait disturbance and myoclonus. He died of bronchopneumonia 5 months after the disease onset.

Exon 3 insert of tau protein in neurodegenerative diseases.

Microtubule-associated protein tau is the major component of the filamentous neurofibrillary lesions of Alzheimer's disease (AD) and other tauopathies. Recently, it has been reported that tau isoforms lacking both N-terminal exon 2 and exon 3 do not form straight filament- or paired helical filament-like filaments in vitro, and that the N-terminal exons facilitate assembly of full-length tau. However, neuropathological and biological studies on the N-terminal region of tau protein in human tissue have been limited.

Influence of repetitive transcranial magnetic stimulation on disease severity and oxidative stress markers in the cerebrospinal fluid of patients with spinocerebellar degeneration.

Ataxia severity, cerebellar hemispheric blood flow (CHBF), ascorbate free radical (AFR), superoxide dismutase protein, superoxide scavenging activity, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in cerebrospinal fluid (CSF) were compared before and after an 8-week course of repetitive transcranial magnetic stimulation (rTMS) in 20 patients with spinocerebellar degenerations (SCD). SCD patients showed higher AFR, 8-OHdG, and superoxide scavenging activity than 19 controls. In SCD patients, AFR and ataxia severity declined, and CHBF increased after rTMS.

An autopsied case of dementia with Lewy bodies with supranuclear gaze palsy.

A 66-year-old man had suffered from a slow and steady decline in both physical and cognitive function for four years. He showed bradykinesia and small step gait with supranuclear vertical gaze palsy, especially upward gaze palsy. He was started on levodopa therapy but without response.
