Why don’t they replace brains the same way as a heart transplant today?
Just replace somebody’s mind (brain) in the same manner as having a heart transplant, but that means disconnecting the old brain from all the nerves, blood vessels and spinal cord and implanting a new brain into them without losing their core functions keeping them in-tact.

Now the doctor has the task on reconnecting all the nerves, blood vessels and the spinal cord, but the question remains: would it still be them or someone else? Would they still have all their senses? Would they regain their basic functions? Are they abled bodied or now a vegetable?

What is bro talking about
that would be more of a body transplant

also, leaving aside all the ethical issues at play, you'd also have to find a way to reattach all the nerves as closely as you can, which just isn't possible with our current technology— not just because of the rejoining of nerves, but because you also need to know which nerves go where in both sides
it's a logistical nightmare

We've done that on dogs but iirc they didn't regain really any bodily control and died within days regardless of the health of the dogs

oh god
Because given current technological limitations, it is simply impossible to maintain the functionality of a separated brain. First, the brain is highly sensitive to oxygen levels, and a drop can cause irreversible damage. Additionally, severing the spinal cord is almost always fatal.
Humans aren’t like the Mi-gos from Yuggoth - we can’t just carry around brains in jars... at least not yet.

In 1959, Soviet scientist Vladimir Demikhov conducted a controversial experiment in which he attached the head of a small dog to the body of a larger one. Without delving into the ethical implications or the horrifying nature of such procedures, the longest survival recorded for one of these two-headed dogs was 29 days

Sadly in 2025 there are no suitable donors left.
All of the brains are defective.

the medical world is trying to get there.

the issue: too many connections to be made, and too thin

for the heart, there are let's say:
- 5 main arteries, big
- about 20ish smaller connection points
- other things that doctors can see

for the brain, there are:
- thousands of micro connections to be made, as veins
- thousands of less than micro connections for the nerve system
- membrane of the brain must be in a good condition and re-sealed
- absolutely no damage done to the brain while being transplanted and oxygen flow undisturbed

as soon as we can solve that, we can try
I thought science had proven that memory is stored in every cell of our body and not only the brain. If that's the case, you would be the same person? i don't know.

there's different types of memory, and I don't mean like long term and short term.

the cells carry a "hardware ID" so to say for your DNA: even when you do an organ transplant from a relative, so someone who shares some of your own blood and DNA, for a lot of time after the procedure you must get medication to suppress the immune system from attacking the transplanted organ

the cells also carry a "location" memory, this is a recent discovery done by researching how to re-start growing of limbs or teeth, and it was found that cells sort of know where they are or should be in your body, based on various chemical levels

however, after a lot of cases of vital organ transplants, it was discovered that the recipients of the organs started to develop certain cravings for food or drinks, based on the preferences of the donor, that's why it was speculated that larger organs also share some of the "general memory", but this could be not a memory per-se, but a chemical craving, so to speak

so, we don't know yet, the research is ongoing.

There are so many ♥♥♥♥♥♥ up experiments, both done in humans and/or animals :lunar2019deadpanpig:

unfortunately, without real experiments, theory and computer simulations only get you so far

we need actual test data from actual trials and procedures in order to level up our medicine tech

Oh me?
Might as well do a lobotomy at this point.
just replace man's brain bro, it's easy bro
