You have found some very interesting information, thank you for sharing it with me. This hospital seems very odd in some regards and very normal in others, don't you agree? It appears to me that it was on one hand a very normal hospital, treating average patients, delivering babies, etc., but in the rear in those "cottages" they were conducting some sort of "treatment" for the Hollywood set who had various addictions, and maybe those so-called treatments were as bad as the ailments people like Judy Garland were suffering from. Of course, she might have been angry and upset and it was her being kept away from whatever she craved that was talking.

As to why your mom was treated there, I can only say that my mother-in-law had brain cancer and when her symptoms first presented the doctor thought she had hypertension and he treated her for that, and when her speech became affected he thought she'd had a stroke (which seemed an odd diagnosis because she wasn't paralyzed). It was only when they transferred her to a hospital that specialized in head injuries did they come up with the correct diagnosis (brain tumor) but then they told the family it was nothing to be concerned about, they'd operate, remove it and she'd be as good as new. Of course she wasn't and ten months later we buried her.

Keep digging.
