BACKGROUND Cognitive impairment is one of the important critical issues in hemodialysis (HD) patients. However, the associating factors of brain atrophy in HD patients have not been fully elucidated. PURPOSE AND METHODS Brain magnetic resonance imaging (MRI) was performed in 34 of total 72 HD outpatients in our dialysis center. These MRI images were analyzed by an application software; Voxel-...

OBJECTIVE To report a case of progressive facial hemiatrophy with unusual features of contralateral brain atrophy and transcranial Doppler ultrasound evidence of autonomic dysfunction. DESIGN Case report. SETTING A teaching hospital. PATIENT A 63-year-old man who presented with a 10-year history of progressive right-sided facial atrophy and recent facial pain. RESULTS Brain magnetic res...

Article abstract—Background: Episodic inflammation in the CNS during the early stages of MS results in progressive disability years later, presumably due to myelin and axonal injury. MRI demonstrates ongoing disease activity during the early disease stage, even in some patients who are stable clinically. The optimal MRI measure for the destructive pathologic process is uncertain, however. Metho...

Background Attention deficit and hyperactivity disorder (ADHD) is a disorder of the brain characterized by periods of inattention, hyperactivity and impulsive behavior. We aimed to evaluate the role of MRI of the brain in children with ADHD. Materials and Methods This prospective study included 100 children with clinical diagnosis of attention deficit and hyperactivity disorder according to the...

Neural network breakdown is a key issue in neurodegenerative disease, but the mechanisms are poorly understood. Here we investigated patterns of brain atrophy produced by defined molecular lesions in the two common forms of genetically mediated frontotemporal lobar degeneration (FTLD). Nine patients with progranulin (GRN) mutations and eleven patients with microtubule-associated protein tau (MA...

The rate of brain atrophy and its relationship to clinical disease progression in progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) is not clear. Twenty-four patients with PSP, 11 with MSA-P (Parkinsonian variant), 12 with Parkinson's disease, and 18 healthy control subjects were recruited for serial MRI scans, clinical assessments and formal neuropsychological evaluations ...

A growing body of evidence has shown that a relationship between age-related hearing loss and structural brain changes exists. However, a method to measure brain atrophy associated with hearing loss from a single MRI study (i.e. without an interval study) that produces an independently interpretable output does not. Such a method would be beneficial for studying patterns of structural brain cha...
