Background: Phase contrast (PC) cine magnetic resonance imaging (MRI) is a valuable method in estimating cerebrospinal fluid (CSF) dynamics that concerns several disease processes. The aim of this work was to estimate the usefulness cine- PC MRI CSF flowmetry patients with normal pressure hydrocephalus (NPH) and differentiate them from involutional brain atrophy.
 Methods: This prospective...

BACKGROUND Previous work suggested greater intellectual enrichment might moderate the negative impact of brain atrophy on cognition. This awaits confirmation in independent cohorts including investigation of the role of T2-lesion load (T2-LL), which is another important determinant of cognition in MS. We here thus aimed to test this cognitive reserve hypothesis by investigating whether educatio...

abstract objective autosomal recessive spinal muscular atrophy (sma) is, after cystic fibrosis, the second most common fatal monogenic disorder and the second most common hereditary neuromuscular disease after duchenne dystrophy. the disease is characterized by degeneration of anterior horn cells leading to progressive paralysis with muscular atrophy. depending on the clinical type (werdnig- ho...

BACKGROUND AND PURPOSE Deferoxamine (DFX) reduces brain edema, neurological deficits, and brain atrophy after intracerebral hemorrhage (ICH) in aged and young rats. Our previous study found that 50 mg/kg is an effective dose in aged rats. In the present study, we explored potential therapeutic time windows and optimal therapeutic durations. METHODS Aged male Fischer 344 rats (18 months old) s...

This paper proposes a model of brain deformation triggered by atrophy in Alzheimer's Disease (AD). We introduce a macroscopic biophysical model assuming that the density of the brain remains constant, hence its volume shrinks when neurons die in AD. The deformation in the brain parenchyma minimizes the elastic strain energy with the prescribed local volume loss. The cerebrospinal fluid (CSF) is...

Excess cortisol levels are linked with brain atrophy and cognitive decline in older people. 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) potently amplifies intracellular glucocorticoid action by converting inert cortisone to active cortisol, but any causal importance in brain aging is unexplored. We tested the hypotheses that higher systemic 11β-HSD1 activity predicts brain atrophy and co...

Acetylcholinesterase inhibitors (AChEIs) are the most commonly prescribed monotherapeutic medications for Alzheimer's disease (AD). However, their underlying neurophysiological effects remain largely unknown. We investigated the effects of monotherapy (AChEI) and combination therapy (AChEI and memantine) on brain reactivity and plasticity. Patients treated with monotherapy (AChEI) (N = 7) were ...

A family with mitochondrial inheritance of multiple system atrophy of the cerebellar subtype. MRI brain shows significant cerebellar atrophy with mild pontine atrophy and the classical hot cross bun sign in Pons. The muscle biopsy was indicative of mitochondrial myopathy. Mitochondrial DNA analysis revealed a low-level large mtDNA deletion, m.3264_1607del12806 bp.
