Did Mary Lincoln need committal?

[JMadonna]

"Insanity" is a legal term not a medical one. Was she a threat to herself or others? Robert thought she was a threat to herself and the court agreed.
Was this the best course of action for her medically? Probably not, but those were the choices at the time.
Luckily she didn't live in the 1950's when she probably would have undergone electro-shock therapy.
