INTRODUCTION Magnetic resonance imaging (MRI) is rarely used as an investigation in clinical psychiatric practice. The reasons for this are several, and include the cultural viewpoint of psychiatry as a psychosocial specialty as well as particular concerns about the experience of brain imaging amongst patients and clinicians. Where MRI is used it is to exclude neurological disorders in those pr...

Moyamoya disease is extremely rare. In children, it one of the rare causes ischemic stroke. We present a 4-year-old female patient diagnosed with Magnetic Resonance Imaging (MRI) and Angiography (MRA). case chronic lacunar infarct in white matter on magnetic resonance imaging, cigarette smoke image characterized by diffuse collateral vascular networks was observed MRA imaging. Since rare, we th...

According to the World Health Organization, mental illness is one of the leading causes of disability worldwide. The first onset of mental illness usually occurs during childhood or adolescence. Neuroimaging and genetic testing have been invaluable in research on behavioral and intentional disorders, particularly with their potential to lead to improved diagnostic and predictive capabilities an...

The main aim of this article is to discuss the current state of in vivo brain imaging methods in the context of the diagnosis and treatment of mental illness. The background to current practice is discussed, and the new methods introduced which may have the capacity to increase the relevance of magnetic resonance imaging, particularly functional magnetic resonance imaging, for clinical applicat...

Human neuro-imaging studies have often reported co-activation of the dorsal premotor cortex (PMd) and the posterior parietal cortex (PPC) during internal operation of visuospatial information, referred to here as "visuospatial mental operation". However, the functions assigned to the PMd and PPC during these tasks are still unclear. Here, we examined the significance of these two areas for a vi...

Background: Different alleles of Fragile X Mental Retardation1 (FMR1) gene with separate molecular etiologies cause Fragile X Syndrome (FXS) and Fragile X-associated Tremor and Ataxia Syndrome (FXTAS). Premutation alleles with 55 to 200 repeats in the FMR1 gene lead to FXTAS. It is carried by 1 in 209 women and 1 in 430 men. FXTAS commonly appears in 50- to 70-year-old adults. Case Presentatio...
