Myelin is the protective sheath that protects nerves and allows them to send signals quickly and efficiently. This insulation deteriorates with age, but scientists now believe they have isolated the gene that causes this to happen.
The finding that neuroplasticity continues as we age has led to development of tools and techniques for medical professionals to promote plasticity in patients and habits everyone can put into practice to promote cognitive health.
Research into combating age-related cognitive decline is happening in many areas simultaneously. That includes a study that uncovered the role a molecule plays in repairing DNA and reversing the aging process.
