I was diagnosed with ADEM when I was 14 years old. It began with flu like symptoms then progressed to constant headaches and urinary retention in a couple of weeks. Once I was admitted to the hospital, many tests were done without a definitive diagnosis. During this time, I developed optic neuritis and an extreme inability to walk. After about one week, a diagnosis of ADEM was made, treatment began, and I was discharged from the hospital after about two weeks. While at home, I still struggled with lack of energy, problems with urination, and walking. Since this acute phase, my symptoms have subsided and I have only had a few relapses of optic neuritis throughout my life.
