Our objective was to evaluate amyloid deposition in posterior cortical atrophy (PCA), using both cerebrospinal fluid (CSF) biomarker analysis and amyloid imaging. Five PCA patients, selected based on their neuropsychological profile and atrophic changes in posterior regions on MRI, underwent CSF analysis. CSF amyloid-beta 1-42, total tau, and phosphorylated… (More)
OBJECTIVE To describe CSF biomarker profiles in posterior cortical atrophy (PCA), which induces high-order visual deficits often associated with Alzheimer disease (AD) pathology, and relate these findings to clinical and neuropsychological assessment. METHODS This prospective observational study included 22 patients with PCA who underwent CSF biomarker… (More)
OBJECTIVE To identify the clinical and radiologic features that should raise suspicion for the pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation (CAA-I). METHODS We retrospectively reviewed the characteristics of 5 newly diagnosed and 23 previously reported patients in whom the CAA-I imaging findings were initially interpreted… (More)
Cerebral venous and sinus thrombosis (CVT) is a rare but potentially alarming condition, which remains a diagnostic and therapeutic challenge. Endovascular procedure may be a therapeutic option when evolution is unfavourable despite medical treatment, but the use of stenting is rarely reported in CVT treatment. We report the case of a man who presented a… (More)
INTRODUCTION Posterior cortical atrophy (PCA) is a clinically and radiologically defined syndrome, in which predominant symptoms focus on higher visual dysfunction with progressive course and association with cortical atrophy or hypometabolism that predominates in the posterior part of the hemispheres. Homonymous hemianopia (HH) has rarely been described in… (More)

BACKGROUND Statins are lipid-lowering drugs widely used in the world. They are effective and safe in the treatment and in the primary and secondary prevention of cerebrovascular and cardiovascular diseases. Besides they are known for their muscular side-effects. It has been suggested that they also have a toxic effect on the peripheral nervous system. … (More)
