Injuries that result in chronic pain, such as limb injuries, and those unrelated to the brain are associated with epigenetic changes in the brain which persist months after the injury, according to researchers at McGill University. Epigenetics explores how the environment – including diet, exposure to contaminants and social conditions such as poverty – can have a long-term impact on the activity of our genes.
