Elevated serum brain natriuretic peptide (BNP) levels are associated with cardioembolic stroke mainly because of atrial fibrillation (AF). However, the mechanisms of increased serum BNP levels are hitherto unclear. We aimed to identify the factors associated with increased BNP levels in patients with acute ischemic stroke. We measured serum BNP levels in(More)
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)
The present multicenter cross-sectional study was performed using semistructured questionnaires to determine the contributing factors of sleep disturbances in Japanese patients with Parkinson's disease (PD). We used the Parkinson's disease sleep scale (PDSS, Japanese version). All data were obtained by means of interviewed questionnaire and physical(More)
OBJECTIVE The purpose of the present study was to clarify the olfactory functions of Japanese patients with idiopathic Parkinson's disease (IPD) using the odor stick identification test for Japanese (OSIT-J). METHODS Fifty-four non-demented IPD patients (33 men and 21 women), ranging in age from 43 to 81 years (69.7+/-8.1 years) and 50 age- and(More)
BACKGROUND Endothelial dysfunction plays a key role in the development of ischemic stroke. However, the relationship between endothelial function and stroke subtypes has not been thoroughly examined. METHODS We measured the percentage of brachial flow-mediated vasodilatation (%FMD) in 62 patients with chronic stroke and 13 age- and sex-matched control(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)
Depression and nocturnal disturbances are frequent in patients with Parkinson's disease (PD). The aim of this study was to determine the correlation between depressive symptoms and nocturnal disturbances in patients with PD in Japan. The subjects of this multi-center cross-sectional study were 188 patients with PD and 144 age-matched controls who were(More)
We report a 63-year-old right-handed man who presented an alien hand syndrome (AHS). He complained of clumsiness of his left hand and admitted to our hospital. On the first examination, he presented left homonymous hemianopia, left spatial neglect and left limb ataxia, but neither paralysis nor sensory impairment. A few days after, he complained that his(More)
