BACKGROUND AND PURPOSE Progressive brain atrophy is a well-known feature of multiple sclerosis (MS). We characterized the spatial evolution of atrophy in different MS phenotypes. METHODS Dual-echo and T1-weighted MR images were obtained in 70 patients with MS and 10 healthy control subjects at entry and after 15 months. Within-group changes in regional atrophy were assessed by applying Struct...

OBJECTIVES The logopenic variant of primary progressive aphasia is an atypical clinical variant of Alzheimer's disease which is typically characterized by left temporoparietal atrophy on magnetic resonance imaging and hypometabolism on F-18 fluorodeoxyglucose positron emission tomography. We aimed to characterize and compare patterns of atrophy and hypometabolism in logopenic primary progressiv...

Jerome J. Graber, MD, MPH Robert Staudinger, MD, FAAN An 82-year-old man presented to us with a 2-year history of progressive difficulty walking. On examination, he had bradykinesia, bradyphrenia, axial rigidity without appendicular rigidity, cogwheeling, or tremor, and restriction of upward and downward gaze. Imaging revealed prominent midbrain atrophy without pontine atrophy, referred to as t...

Th e abundance of grey matter damage in multiple sclerosis and its clinical relevance is currently fully recognized. Although previous studies have provided information regarding determinants of grey matter atrophy and its relationship with disability in multiple sclerosis, the majority of these studies were limited by their sample size. Th e objectives of the current study were therefore to: 1...

PURPOSE To evaluate the costs and efficacy of type A botulinum toxin in the treatment of essential blepharospasm and hemifacial spasm. METHODS Pacients with essential blepharospasm and hemifacial spasm had their files analyzed. All patients were treated with type A botulinum toxin (Dysport) between April 2002 and May 2004 at the Oculoplastic Clinics of "Santa Casa de São Paulo". Twenty-seven ...

Background: Several case studies have described the use of the superficial inferior epigastric artery (SIEA) flap as a pedicled flap for reconstruction of upper and lower ex tremities, or a free fasciocutaneous flap when a large amount of skin coverage is required for hemifacial atrophy, breast or head and neck reconstruction. Apparently, the anatomical findings of previous studies are relative...

BACKGROUND Dentatorubropallidoluysian atrophy (DRPLA) is a rare autosomal dominant neurodegenerative disease that is associated with numerous movement disorders. Ocular problems also occur with DRPLA with reports of corneal endothelial degeneration in some patients living with the disease. We report a new visual problem associated with DRPLA, optic atrophy. CASE PRESENTATION A 47 year-old man...

Background & Importance: Primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. Secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. We review and discuss the pathophysiology and the literature ...

Frontotemporal lobar dementia (FTLD) is a heterogeneous group of neurodegenerative diseases. FTLD encompass: 1) behavioral forms, sometimes associated with amyotrophic lateral sclerosis; 2) linguistic forms (semantic and non-fluent primary progressive aphasia); 3) atypical parkinsonian syndromes (progressive supranuclear palsy and corticobasal syndrome). Standard brain MRI allows for strengthen...
