Using diffusion tensor MRI tractography, Migliaccio et al. The clinical presenta-tions fulfilled the criteria of posterior cortical atrophy [1]. The atrophy was predominant on the left side (Figure 1). This area of the brain is responsible for processing what and how we see. Introduction. In this test, your doctor can view abnormalities in your brain that may be causing your symptoms. Posterior cortical atrophy (PCA), also called Benson's syndrome, is a form of dementia which is usually considered an atypical variant of Alzheimer's disease (AD). INTRODUCTION. Posterior cortical atrophy (PCA) is a rare progressive neurodegenerative disorder that causes damage and deterioration to the back, or posterior, region of the brain. different from Figure 1. An associated marked mid brain atrophy. Brain scans including MRI and PET or SPECT scans are often part of the testing. She was prescribed an acetylcholinesterase inhibitor. An MRI machine uses powerful radio waves and a magnetic field to create a 3-D view of your brain. ... Posterior cortical atrophy can't be cured, but your doctor can help you manage your condition. Please click here to watch an updated version of this film http://www.youtube.com/watch?v=nOxodew_ngo An MRI rules out strokes, tumors , and other structural problems while looking for characteristic “atrophy” or … Magnetic resonance imaging (MRI). It is known as a visual variant, meaning it primarily affects an individual's vision, and it may impact cognitive function as it progresses as well.

Loss of visual skills is the predominant effect of this condition. Figure 1: Axial T1-weighted image showing predominant parietal and occipital atrophy, with sparing of the frontal and temporal lobes Atrophy and decreased activation of fronto-parietal attention areas contribute to higher visual dysfunction in posterior cortical atrophy. Homepage / Posterior cortical atrophy (PCA) Posterior cortical atrophy (PCA) A A A. PCA is a rare form of dementia which can initially cause difficulties with seeing what and where things are, for example, when you’re driving or reading. Magnetic Resonance Imaging (MRI) demonstrated bilateral oc-cipito-parietal and occipito-temporal atrophy. Posterior cortical atrophy is a rare, degenerative brain and nervous system (neurological) syndrome that results in gradually declining vision. Posterior cortical atrophy is a rare clinicoradiologic neurodegenerative syndrome, and two sets of clinical diagnostic criteria for PCA have been proposed [7, 8]. The disease causes atrophy of the posterior part of the cerebral cortex, resulting in the progressive disruption of complex visual processing. ... or other specialists. Posterior Cortical Atrophy (PCA) is a syndrome in which people experience difficulties seeing the world around them, due to degeneration not of the eyes but of areas at the back of the brain which process visual information. Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association; Alzheimer’s & Dementia: Translational Research & Clinical Interventions Ultra-High Resolution MRI Study in Posterior Cortical Atrophy and Alzheimer's Disease We are excited to be collaborating with the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, on an exciting new study which will be using ultra-high resolution MRI imaging to study posterior cortical atrophy and Alzheimer's disease. Posterior cortical atrophy (PCA) is characterized predominantly by visual dysfunction that arises from bilateral impairments in occipital, parietal, and temporal regions of the brain.
