Did Mary Lincoln need committal?

[Donna McCreary]

I always avoid attaching modern illness to historic figures since we do not have access to modern medical testing for them. However, I am about to do just that . . . . I have always been surprised that so many modern readers are quick to attach illnesses to Mary such as depression, mental breakdown, brain tumor, so forth, but very few discuss the possibility that she suffered from post traumatic shock disorder. If you look at the list of events in her life posted earlier, any one of them could have created PTSD. The combination of all of them presents a good case for the disorder.
I have always been inclinded to think she suffered from PTSD and it escalated until she had a nervous breakdown. But this, like so many things involving Mary, is purely speculation.
