Misophonia: Scientists Crack Why Eating Sounds Can Make People Angry (bbc.com)

An anonymous reader quotes a report from BBC: Why some people become enraged by sounds such as eating or breathing has been explained by brain scan studies. The condition, misophonia, is far more than simply disliking noises such as nails being scraped down a blackboard. UK scientists have shown some people's brains become hardwired to produce an "excessive" emotional response. Olana developed the condition when she was eight years old. Her trigger sounds include breathing, eating and rustling noises. Scientists, including Olana, at multiple centers in the UK scanned the brains of 20 misophonic people and 22 people without the condition. They were played a range of noises while they were in the MRI machine, including: neutral sounds such as rain; generally unpleasant sounds such as screaming; people's trigger sounds. The results, published in the journal Current Biology, revealed the part of the brain that joins our senses with our emotions -- the anterior insular cortex -- was overly active in misophonia. And it was wired up and connected to other parts of the brain differently in those with misophonia. Dr Sukhbinder Kumar, from Newcastle University, told BBC News: "They are going into overdrive when they hear these sounds, but the activity was specific to the trigger sounds not the other two sounds. The reaction is anger mostly, it's not disgust, the dominating emotion is the anger -- it looks like a normal response, but then it is going into overdrive." There are no treatments, but Olana has developed coping mechanisms such as using ear plugs. It is still not clear how common the disorder is, as there is no clear way of diagnosing it and it was only recently discovered. Ultimately, the researchers hope, understanding the difference in the misophonic brain will lead to new treatments. One idea is that low levels of targeted electricity passed through the skull, which is known to adjust brain function, could help.

The didn't crack anything.

Another misleading headline. They didn't crack anything. Was there seriously anyone who doubted for one millisecond that that feeling was not somewhere in the brain? Of course it bloody is. The scans didn't reveal anything except a location that shows more activity when the condition occurs, and –suprise, surprise– it's an area known for precisely this.

But did they discover what sets up this association? No. Why these people experience it so strongly? Neither. So no cracking, just "located the area", and even that's surrounded by uncertainty given the experimental conditions.

"...break-up more households than infidelity."

Why is it good to close your mouth when you eat?

1. You won't spray all over everyone and everything while you masticate.
2. More food makes it into your gut, so you're less of a wasteful slob in an otherwise hugely wasteful age.
3. People won't have to raise their voices to have a conversation over your meat-flapping noises.
4. You won't announce your gastronomic preoccupation to predators.

Yes, easy. Learn some manners.

doctors can simply cauterise it so the rest of us can carry on munching, crunching and slurping like normal humans.

I'm 100% unimpressed by the fact that either no one took the time to teach such folk manners, or that having been taught, they failed to integrate these basic socializations. While it may be polite to slurp in China, it isn't most other places. Consequently, it's not okay to slurp here, just because it's okay to slurp in China.

People can certainly chew with their mouths open, talk as loudly as they want, mumble, hold their tableware like a monkey with a broken wrist, face-dive into their dishes while eating, drool, snort, ignore personal grooming, blow their nose at the table, bang their tea/coffee cup with their spoon, fail to hold doors for others, fail to keep appointments, never say thank you, start their sentences with "me and...", fail to show up when they said they would, slurp their drinks and soups, dive into their cellphones at meals, drive down the street with their windows down and their audio maxed out, cut in line...

But I feel no obligation to respect or forgive them for any of it, or subject myself to their company, or keep them on as an employee.

There's nothing wrong with any of these things that some (very) basic socialization wouldn't cure. I consider my ostracization of adults exhibiting these characteristics to be nothing less than my social duty.

TLDR: It is incumbent on us to learn basic manners and consideration; also, being moderately irritated by inconsiderate social behavior isn't a syndrome. It's evidence of being civilized.

Raging at such things is something else again.
