Postoperative delirium (POD) is characterized by the progressive deterioration of sensory/cognitive function after surgery with incidences of up to 30-80%. It is frequently followed by postoperative cognitive dysfunction (POCD) which tends to persist over time. In elderly patients, POCD resembles chronic dementia and appears to accelerate the...

During the past decades, exceptional progress was made with in vivo medical imaging technologies to capture the anatomical, structural and physiological properties of tissues and organs in a patient, with an ever increasing spatial and temporal resolution. The physician is now faced with a formidable overflow of information, especially when a...

In this project, D. Salas-Gonzalez proposes to develop brain image processing with alpha-stable distributions with applications to intensity normalization, segmentation and diagnosis of Parkinsonian syndrome and Alzheimer's disease. The expected results of this interdisciplinary project will definitely have applications and impact in the European...

The cerebral microvascular system is essential to a large variety of physiological processes in the brain, including blood delivery and blood flow regulation as a function of neuronal activity (neuro-vascular coupling). It plays a major role in the associated mechanisms leading to disease (stroke, neurodegenerative diseases, …). In the last decade...

Alzheimer’s disease is the most common form of dementia which seriously interferes with the daily life of millions of people. People suffering from Alzheimer’s disease show the accumulation of two misfolded proteins in the nerve cells of their brains – amyloid plaques and tau tangles. Although many aspects of the Alzheimer’s disease pattern are...

Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) are fatal neurodegenerative diseases with overlapping genetics and pathology. The most common known cause is expansion of a GGGGCC repeat in the first intron of the gene C9orf72. I discovered that the repeat region is translated in all three reading frames into aggregating...

With increased life expectancy, there has been a critical growth in the portion of the population that suffers from age-related cognitive decline and dementia. Attempts are therefore being made to find ways to slow brain-aging processes; successful therapies would have a significant impact on the quality of life of individuals, and decrease...

The search for the fundamental mechanisms of learning and experience-dependent memory formation in the brain has long been a central quest in neuroscience. The neocortex is a particularly relevant region for plasticity because it is involved in sensory, motor, and cognitive tasks with strong learning components. However, despite many years of...

Alzheimer’s disease (AD) is the leading cause of dementia in the elderly. Accumulating evidence links AD with vascular risk factors. These correlations, together with profound alterations of cerebrovascular structure and function present in AD, suggest a “vascular hypothesis”, where vascular pathology eventually leads to neurodegeneration and...

New perspectives are opening in neuroscience: the era of electricity is transitioning into the era of light. Super-resolution microscopy was elected “Method of the year 2008” and optogenetics “Method of the year 2010” by the Journal Nature Methods. HOLOSTED is a biophysics project using these modern optical methods to study the effects of Alzheimer...

Influenced by the developments in information and communication technologies and pressured by the dramatic changes in demographics in our societies, health care is and must be transforming to remain viable and of high quality. An important element in such changing health care is the emergence of personal health systems. Based on smart home...

CHANCES aims at combining and integrating on-going cohort studies in order to produce evidence on ageing-related health characteristics and determinants in Europe, and their socio-economic implications. 15 cohorts participate, covering populations from 18 EU Member States, 4 associate countries, and 3 additional countries. The combination of these...
