How long have you been treated for PTSD? They also look at how long you’ve had your condition. For example, a person suffering from PTSD for a month (while it affects most aspects of their life) may be deemed retainable. PTSD is considered manageable and treatable in many cases. So the MEB looks at how long you’ve had treatments, what treatments you’ve had, and your response to them. For me (MDD/OCD/PTSD), I had counseling for about 2 years, on 6 different meds, and I had received 20+ ECT treatments. So in the eyes of the MEB, my conditions affected pretty much all aspects of my life, with minimal response to treatment, AND I had exhausted all treatment options.
