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

Myelin acts like the protective and insulating plastic casing around the electrical wires of the braincalled 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…
