1) Article says 50%-75% reduction. NOT 80%
2) The images have no provenance.
3) The man is not named.
4) The actual image may be selected to show worst contrast.
5) This is not a scientific article and "New Scientist" are a populist rag, not averse to a bit of audience manipulation and sensationalism.
(2016) Meet The Man Who Lives Normally With Damage to 90% of His Brain
A French man who lives a relatively normal, healthy life - despite damaging 90 percent of his brain - is causing scientists to rethink what it is from a biological perspective that makes us conscious.
Despite decades of research, our understanding of consciousness - being aware of one's existence - is still pretty thin. Many scientists think that the physical source of consciousness is based in the brain, but then how can someone lose the majority of their neurons and still be aware of themselves and their surroundings?
First described in The Lancet in 2007, the case of the man who appears to be missing most of his brain has been puzzling scientists for almost 10 years.
Not only did his case study cause scientists to question what it takes to survive, it also challenges our understanding of consciousness.
In the past, researchers have suggested that consciousness might be linked to various specific brain regions - such as the claustrum, a thin sheet of neurons running between major brain regions, or the visual cortex.
But if those hypotheses were correct, then the French man shouldn't be conscious, with the majority of his brain damaged.
"Any theory of consciousness has to be able to explain why a person like that, who's missing 90 percent of his neurons, still exhibits normal behaviour," Axel Cleeremans, a cognitive psychologist from the Université Libre de Bruxelles in Belgium"

The case appears to be important for theories about the origin of consciousness. If humans can be conscious without a brain, then the idea that plants are conscious creatures becomes more plausible.
There are many similar cases:

The student was bright, having an IQ of 126. The doctor noticed that the student's head seemed a little larger than normal and he referred him to Dr Lorber for further examination. Dr Lorber examined the boy's head by Cat-scan to discover that the student had virtually no brain.

Noah Wall was born with less than 2% of a brain - but he has amazed medics by growing into a happy, chatty little boy
https://www.mirror.co.uk/tv/tv-news/boy ... rs-9778554
As a child he suffered from hydrocephalus, and so his cerebral development was different.
The Lancet remarks that he had low IQ on three categories.
The brain still grew, but around the water filled vacuole.
I do not think this qualifies as a mystery and does not support any attempt to separate the genesis of mind from the cerebral structure. Far from it is, it verifies and asserts the necessary connection between a healthy brain and intelligence.
When you unpack the sensationalism from the facts, you get an interesting story about the histology and ontogenesis of the brain.
