Lifting heavy kills brain cells

[Entity]

Say your doing a one rep max youre all psyched and pissed which releases cortisol which is known to kill brain cells then you get under the bar, lets say its a squat, and walk out.. your whole body tight, now you decend and at the very bottom explode out, eyeballs puppong out of your head, face near purple from lack of oxygen, then you stand up and re-rack the weight.
It seems that that would be very taumatic to the brain considering the extremely elevated blood pressure in conjunction with the lack of oxygen and stress. Think about it what does alchohol and weed kill brain cells: lack of oxygen to the brain...well a max lift, would be like smoking a godfather and downing an entire pint of wiskey in 3 seconds in that respect.
what do you think of this hypothesis?

Unlikely

Unless you were to actually sustain a stroke, you needn't worry about this.

People live with some ungodly high blood pressures day in and day out (uncontrolled hypertension of, say 210/120), and seem to not suffer immediate ill effects. There ARE long-term effects, and the risk of blowing an anurysm is there, but the transient elevation in BP and cortisol levels experienced in lifting is highly unlikely to cause problems, unless it uncovers one waiting to happen - like an anurysm. The lack of oxygen is not total, but may be reduced for the few seconds it takes to do the lift. As long as the brain doesn't go without oxygen for more than 3 minutes or so, this shuoldn't be a problem. Blood vessels in the brain dilate in resonse to lowered oxygen delivery in order to enhance perfusion.

Much more traumatic is the type of brain injury sustained by being knocked out - diffuse axonal injury (DIA). Here, the shearing force applied as the brain shifts violently in the skull can shear blood vessels, and produces damage to the axons on the cells in the brain.
