I love science and especially neuroscience, so the article was of particular interest to me. Often, when I feel lethargic, I have to stop and think, is this the inflammation of Crohn's Disease or is this depression? Most of the time, it ended up being Crohn's inflammation, but not always. Perhaps, it is sometimes easier for me to believe it is depression because I feel like I might have some control over it and with Crohn's disease other than taking my medicine and living a healthy lifestyle, I have very little control of the course of the disease.
