Patients rarely experience visual hallucinations while being observed by clinicians. Therefore, instruments to detect directly from patients are needed. Pareidolias, which complex illusions involving ambiguous forms that perceived as meaningful objects, analogous and have the potential be a surrogate indicator of hallucinations. In this study, we explored clinical utility newly developed instrument for evoking pareidolic illusions, Pareidolia test, in with dementia Lewy bodies—one most...
Frontal lobe dysfunction is believed to be a primary cognitive symptom in idiopathic normal pressure hydrocephalus (iNPH); however, the neuropsychology of this disorder remains fully investigated. The objective study was delineate comprehensive profile iNPH and evaluate effects cerebrospinal fluid (CSF) shunt surgery on dysfunction.A total 32 patients underwent neuropsychological testing memory, attention, language, executive function, visuoperceptual visuospatial abilities.

A system of self-sustained biological clocks controls the 24-h rhythms behavioral and physiological processes such as sleep–wake cycle. The circadian clock is regulated by transcriptional translational negative feedback loops multiple genes. Polymorphisms in genes have been associated with morningness–eveningness (diurnal) preference, familial advanced sleep phase type (ASPT) delayed (DSPT). We genotyped single-nucleotide polymorphisms 182 DSPT individuals, 67 free-running (FRT) individuals...
Sleep can be characterized along multiple dimensions. We investigated whether an aggregate measure of sleep health was associated with prevalent and incident clinically significant depression symptoms in a cohort older women. Participants were women (mean age 80.1 years) who completed baseline (n = 6485) follow-up 3806) visits, approximately 6 years apart, the Study Osteoporotic Fractures (SOF). Self-reported over past 12 months categorized as "good" or "poor" across 5 dimensions:...
To clarify the neural correlates and brain activity during progression of human non-rapid eye movement (NREM) sleep, we examined absolute regional cerebral blood flow (rCBF) light deep NREM sleep wakefulness in normal humans using positron emission tomography with H 2 15 O. Relative changes rCBF comparison to were also analyzed. During midbrain, contrast that pons thalamic nuclei, did not decrease when compared wakefulness, whereas decreased left medial frontal gyrus, inferior parietal gyrus...
