For the 14.8 million Americans (about 6.7 percent of the population) who wrestle with recurrent depression, here’s another reason why treatment is so vital: It could save your memories. A group of global research institutes compiled their studies and researchers found that those with depression had smaller hippocampuses—the area of the brain that stores memories, forms new ones and creates emotional connections to them. But there is good news. Researchers believe that, with treatment, the damage to the hippocampus can be reversed. And, according to one of the study’s leaders, treatment doesn’t necessarily have to involve medication to start seeing promising results. For example, fish oils are believed to be ‘neuro-protective’ and you can also try and take steps (no matter how small) to be more socially engaged. Volunteering, walking at the park or joining a book club are just a few examples. If you or anyone you know has been affected by depression, what treatments proved most effective?
