A very serious (and highly misunderstood) symptom of Sensory Deprivation Disorder -- itself a symptom of Autism Spectrum Disorder -- where a
person gets too overwhelmed by the world around them, causing extremely irrational behavior.
The most common cause is too much noise, especially the sounds of multiple
people talking at once. However, one loud talker (or one loud, irritating sound) is usually enough to
trigger it. When a
person is going into sensory overload, they will usually exhibit signs of extreme distress, such as clutching their head to shield their eyes and/or ears. They
may become extremely irritable, lashing out at just about anyone. They
may also wince or flinch if it comes on suddenly.
People who suffer from it often describe the feeling as though they are being attacked, and that their mind is so clouded that they lose all rational thought. And of course, being a symptom of
autism, there is no cure.
If you see someone exhibiting these symptoms, especially the wincing, you should immediately shut the fuck up and make sure everyone in the room does so too. The only way to stop a bout of sensory overload is for everything to be totally silent for about 15-30 minutes.
If you want to know what sensory overload feels like, listen to the
music that plays during the Death
Egg Zone in Sonic 2, before the two final bosses. Everything feels terrifying and distorted, while your mind is just trying to calm down and pretend that everything is okay when it's not.
It's a very
real disorder and it deserves more attention.
