Brain’s ‘wiring insulation’ as major factor of age-related brain deterioration – Study

A new study led by the University of Portsmouth has identified that one of the major factors of age-related brain deterioration is the loss of a substance called myelin.

Myelin acts like the protective and insulating plastic casing around the electrical wires of the brain – called axons. Myelin is essential for superfast communication between nerve cells that lie behind the supercomputer power of the human brain.

The loss of myelin results in cognitive decline and is central to several neurodegenerative diseases, such as Multiple Sclerosis and Alzheimer’s disease. This new study found that the cells that drive myelin repair become less efficient as we age and identified a key gene that is most affected by ageing, which reduces the cells ability to replace lost myelin.

  1. I must try and forget this! 😉 Mind you, my lack of myelin will probably do it for me!
