Background: Schizophrenia often involves persecutory delusions, which cause psychological distress. Some patients use online gaming as a coping tool. However, excessive online gaming has raised concerns about internet gaming disorders (IGD), while any soothing effects of online gaming on psychological distress remain unclear.

However, few studies have predicted the presence of comorbid LB pathology with AD using indicative biomarkers of dementia with Lewy bodies or by collecting detailed clinical symptoms. We report the clinical progression of a 67-year-old patient diagnosed with AD who developed rapid eye movement sleep disorder-like symptoms and transient visual hallucinations 10 years after AD onset and was considered to have comorbid LB pathology based on imaging indicative biomarkers of dementia with Lewy bodies.
View Article and Find Full Text PDFDementia with Lewy bodies (DLB) is strongly associated with Alzheimer disease (AD)-type pathology and tends to mask the core clinical features of DLB. Therefore, there may be cases of undiagnosed DLB without suggestive biomarkers of DLB. We describe the case of a 63-year-old woman who was initially diagnosed as having AD and later diagnosed with DLB based on suggestive biomarkers of DLB.

Functional magnetic resonance imaging studies have repeatedly shown the activation of Broca's area in response to syntactic tasks.

We compared the degree of atrophy in medial temporal structures between the two types of dementia using the voxel-based specific regional analysis system for Alzheimer's disease (VSRAD).
Methods: The participants included 29 (age: 61.
A hetero-tetranuclear CeNi complex with a macrocyclic ligand catalysed the aerobic oxygenation of a methylene group adjacent to a carbonyl group under visible-light radiation to produce the corresponding α-diketones. The visible-light induced homolysis of the Ce-O bond of a bis(enolate) intermediate is proposed prior to aerobic oxygenation.

A 57-year-old man with an infarct involving the right posterior insula presented with reduced somatosensory response in the upper and lower left extremities. Furthermore, there was a reduced response to noxious stimulation in the right upper and lower limbs.
View Article and Find Full Text PDFNumbsense is a phenomenon, wherein patients can correctly respond to somatosensory stimuli at a higher rate than expected by chance, but cannot perceive the same stimuli consciously. Previously, numbsense has been reported in tactile localization of stimuli on the patient's own body. Here, we describe a patient with numbsense that involved touched objects.

In contrast to the current concept of PiD, the presence of Pick bodies (tau-positive inclusions) was not thought to be necessary for the diagnosis of PiD. Four out of the seven patients in his original paper had predominant left temporal atrophy and language related symptoms corresponding to semantic dementia.

Ramelteon is a novel hypnotic characterized by its action as a melatonin receptor (MT1/MT2) agonist. It has been reported that ramelteon can alter the phase of the sleep period. We report a patient with circadian rhythm sleep disorder and mood disorder who improved with ramelteon.

Methods: Among the patients hospitalized in our department between 2004 and 2010, we analyzed the records of 67 patients who required emergency admission for severe hypoglycemia and were aged 60 years or older. Comparisons were made between those admitted during the warm season (April-September) and those in the cold season (October-March).
Purpose: In previous reports, it was demonstrated that bone marrow adipocytes were related to steroid osteoporosis through osteoclastogenesis induced by Receptor Activator of Nuclear factor κ-B Ligand (RANKL) expression. The purpose of this study was to evaluate the effect of Tumor necrosis factor-alpha (TNF-α) on RANKL expression in bone marrow adipocytes, and osteoclast differentiation supported by human bone marrow adipocytes.
Methods: RANKL, osteoprotegerin (OPG), and macrophage-colony stimulating factor (M-CSF) mRNA expression in bone marrow adipocytes and their regulation by TNF-α treatment were measured by real-time RT-PCR.
Background: Osteonecrosis of the femoral head is a common complication of high-dose glucocorticoid treatment. Intravascular thrombosis is thought to be associated with the ischemic state of the femoral head. Plasminogen activator inhibitor-1 (PAI-1) is an adipokine, which are physiologically active substances secreted from visceral and subcutaneous adipocytes.
