Exercise protects against Alzheimer's

Doing physical exercise constantly and for pleasure, creates a protective effect and therapeutic against Alzheimer's. This was ensured by the study of the CSIC (Spanish State Agency for Scientific Research) of Spain, which was published in the journal Journal of Alzheimers's Disease.

The researchers found that these activities improve theneuronal synaptic functions , learning, memory, sensorimotor function and anxiety.

The investigation was based on the analysis of several groups of 3xTg-AD transgenic mice with a pathology similar to Alzheimer's. The experts separated the animals according to the progress of the disease and each group had access to the spinning wheel for a different time and in different stages of the disease.

Sick mice that did not exercise presented:

  • Psychological symptoms of dementia Y cognitive loss
  • Alterations in some mechanisms that influence the memories and the learning
  • Worst function sensorimotor

The mice that did exercise obtained:

  • Better results in all psychomotor tests
  • Better results in the tests of memory Y learning
  • Less anxiety before stressful situations
  • Better control of the response before startles

The research team also analyzed the tissue of the cerebral cortex and the hippocampus, which are affected by the disease and observed that oxidative stress in the brain obtained better results in the animals that exercised, "which reveals the importance of voluntary exercise. and moderate as a factor of neuroprotection "Explains Coral Sanfeliu, CSIC researcher at the Biomedical Research Institute of Barcelona and leader of the study.
