Leg exercise is critical to brain and nervous system health

Groundbreaking research shows that neurological health depends as much on signals sent by the body's large, leg muscles to the brain as it does on directives from the brain to the muscles. Published today in Frontiers in ...

Single protein causes Parkinson's disease and multiple system atrophy

Several neurodegenerative disorders are caused by aggregates of a single protein known as alpha-synuclein. In collaboration with CNRS and the University of Antwerp, KU Leuven neurobiologists have discovered that the shape ...

Atrophy

Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise or disease intrinsic to the tissue itself. Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic.

Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. When it occurs as a result of disease or loss of trophic support due to other disease, it is termed pathological atrophy, although it can be a part of normal body development and homeostasis as well.
