I've always thought it interesting as well that such awful damage with terrible behavioural consequences can only be diagnosed post mortem.

Yes, that was mentioned in the media item I saw. A brain tumour had been suspected, he had scans and nothing was found.
Link to an article about the rugby player, Billy Guyton.

The article says that tau proteins are markers of the damage. In that case, there are ways to test the living brain e.g. this written for Alzheimers
Until a few years ago, tau and beta-amyloid levels in a person with dementia could only be measured after the person had died. Now, however, tau and beta-amyloid levels can be measured in living individuals by analyzing samples of cerebrospinal fluid (CSF), the fluid surrounding the brain, and by using positron emission tomography (PET) scans and special dyes to show tau tangles and beta-amyloid plaques in the brain. Scientists are beginning to use CSF analysis and PET scans to study how possible tau and beta-amyloid interactions may speed the brain changes that ultimately result in memory loss and other symptoms of Alzheimer’s dementia.

Interesting, thanks. I do vaguely remember reading something more recently about how there was now a way in some victims of CTE to see some evidence. Perhaps that was it.

CNN: NIH cancels ‘Havana syndrome’ research, citing unethical coercion of participants

The NIH said it would end the work “out of an abundance of caution” after an internal investigation found that people had been coerced into to being part of the research.

The coercion, the agency specified, was not on its own part, but the NIH did not elaborate as to who may have forced the participation. However, it noted that voluntary consent is a fundamental pillar of the ethical conduct of research.

Havana syndrome: Pentagon gets its hands on a device suspected of being linked to it​

For the past year, the US Department of Defense has been conducting tests on a device that emits pulsed radio waves. Some investigators suspect it is the cause of the mysterious “Havana syndrome,” CNN reported. Four sources close to the case told the media outlet that US authorities obtained the device through an undercover operation. With Pentagon funding, Homeland Security Investigations (HSI) purchased the device at the end of former President Joe Biden’s term. However, CNN’s anonymous sources did not specify the exact amount, saying only that it was in the tens of millions of dollars.
