Exercise improves cognitive function in people at risk for Alzheimer's. Specifically, physical activity increases the efficiency of brain activity associated with memory, according to the Journal of Alzheimer's disease.
Cellular aging caused by the passage of time is the cause of the neurodegenerative and cardiovascular diseases most feared by the population. The study carried out by a team of Italian doctors affirms that cancer and Alzheimer's are two symptoms of old age that do not usually develop simultaneously in the same person due to their incompatibility.
The software used to process the images taken by satellites from space has created a simple method to study Alzheimer's disease among the population. This is the AlzTools 3D Slicer tool, which uses spatial routines to analyze magnetic resonance images and has been developed by computer engineers from the Spanish company Elecnor Deimos and experts from the Polytechnic University of Madrid, based on the experience accumulated during the years of software development for the Envisat mission of the European Space Agency (ESA).
If two people suffered similar strokes, it would seem logical to think that the effects on their mental functions would be similarly serious. However, it's not always like that. Some people seem to have more brain protection than others from brain disease. What does that depend on? Well, among other things, of our 'cognitive reserve'.
The contacts between neurons (synapses) with five times smaller in the areas of the brain that suffer from Alzheimer's, according to a study by the Higher Council for Scientific Research (CSIC) published in the journal 'Journal of Alzheimer's Disease'.
When we suffer prolonged stress, steroids increase in the blood, including allopreganolone, a substance derived from progesterone that previous studies link with anxiety and depression. As Sara K. Bengtsson, from Umea University (Switzerland) has shown, this substance accelerates the development of Alzheimer's in mice, which also suffer a rapid deterioration of the ability to learn and memory when these substances are increased.
Performing activities that involve a novelty protects against Alzheimer's disease, according to a study done with laboratory mice published in the journal Neuron. In addition, researchers have discovered the mechanism by which stimulating activities for the brain is so beneficial.
Vitamin D and omega-3 docohexaenoic acid (DHA) enhance the immune system's ability to clear amyloid plaques that settle in the brains of Alzheimer's disease patients, a team's latest study reveals of researchers from the University of California (USA).
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
