To evaluate the effect of the odor of incense on brain activity, electroencephalograms (EEGs) and event-related potentials (ERPs) in a push/wait paradigm were recorded in 10 healthy adults (aged 23-39 years) with normal olfactory function. EEG was recorded from 21 electrodes on the scalp, according to the International 10-20 system, and EEG power spectra(More)
We report a case of a 54-year-old man with sudden-onset double-vision. On admission, neurological examination showed upward and downward gaze palsy on voluntary and smooth pursuit movements, and vertical oculocephalic maneuver elicited a full upward and downward response. Bell's phenomenon, horizontal eye movements and convergence were not impaired. Based(More)
A case is reported of a patient with bilateral internuclear ophtalmoplegia which followed a single limited lesion of the two medial longitudinal fasciculi (M.L.F.), with degeneration of the right internal nucleus. The authors feel that the exact localization of this minute lesions, associated with right internal nucleus degeneration, can assist in supplying(More)
Autonomic and olfactory dysfunctions are considered markers for preclinical diagnosis in Parkinson's disease (PD), because pathological changes in these systems can start before motor symptoms develop. We investigated whether cardiac sympathetic function and olfactory function are associated in PD. Participants comprised 40 nondemented patients with(More)
Odor impairment and its relationship with TAR DNA-binding protein 43 (TDP-43) pathology in patients with amyotrophic lateral sclerosis (ALS) have not been fully elucidated. We performed the odor stick identification test for Japanese (OSIT-J) in 18 ALS patients and in 18 controls. The score was significantly decreased (6.6 ± 2.7) in the patients versus the(More)
A 16-year-old girl developed acute left choreic movements during her fourth week of pregnancy. She had sometimes had transient ischemic attacks since she was 10 years old. During the eighth week of pregnancy, a brain MRI showed old ischemic lesions deep in the right frontal white matter. Her angiograph revealed a complete obstruction of the terminal portion(More)
In Parkinson's disease (PD), sudden unexpected sleep episodes and excessive daytime sleepiness (EDS) while driving and engaging in social activities are important problems. We conducted a multi-center study to clarify the prevalence and contributing factor of EDS and sleep episodes in Japanese patients with PD. We evaluated 188 patients with PD (85 men, 103(More)
OBJECTIVE The long-term use of levodopa to treat Parkinson's disease (PD) is often limited by the development of motor complications (e.g., levodopa-induced dyskinesia, LID). We hypothesized that a non-ergot dopamine agonist with strong affinity for D3) dopamine receptors (pramipexole) may improve LID in patients taking an ergot D1/D2 dopamine agonist. (More)
