If you RTFA he's been selling shares steadily over the last year. This is not exactly a sudden dump.

Sometimes you do not have the luxury of waiting to treat until you have all information. In general a short course of steroids is extremely safe. Additionally, steroids are correct to give in CNS helminth infections anyways, although usually it is dexamethasone, not prednisolone. More likely the mycophenolate was the immunosuppressant that let it get into the brain not the steroid.
More importantly, they did quite a bit of workup, including bronchoscopy with BAL, which indicated she likely had a form of eosinophilic pneumonia, probably Churg-Strauss syndrome. Steroids and immunosuppressants are the standard of care for this, and it is a severe disease if not treated.
This is something that has never occured before in known medicine, so to expect them to have figured it out entirely before initiating a treatment is unreasonable. Her initial symptoms were in January of 2021, final diagnosis was made mid 2022. Would you expect your doctor to hold off on any treatment for a year and a half?

The term you are looking for with the "death punch" is Commotio Cordis.
Also, to be more technically accurate, defibrillators are intended to restart a stopped heart, but only some kinds of stops. What people traditionally think of is Asystole ("flatline"), which is complete lack of electrical activity in the heart. Shock won't do diddly here, they ded.
Ventricular tachycardia and ventricular fibrillation however have essentially stopped the muscular/mechanical pumping of the heart, because of disjointed electrical activity. This activity is what the defibrillator is intended to reset.
There's a 4th type called Pulseless Electrical Activity (PEA) where the electrical function is relatively normal, but something external is preventing pumping. Defib won't help here either, since the electrical portion is working fine.
I think you mean "amenities" rather than "enmities."
