When little sounds drive you wild!

Misophonia is a common sensory processing struggle. It happens to individuals outside the autism spectrum too. https://www.webmd.com/mental-health/what-is-misophonia

Recent studies, as quoted above show misophonia is a sensory processing disorder and most likely neurological in nature. No wonder Autistic individuals seem to experience this struggle more frequently.

The drip drip drip of water from the tap into the sink, the mouth breathing or open mouthed chewing of somebody across the room from you, the tapping of a branch on the window, or the clicking or tapping from toes, a constantly barking dog, anything can be the focus of this deeply frustrating processing disorder.
we can become anxious, furious, and even outraged at the percieved intrusiveness of the triggering sound or sound. This is not helpful to having good relationships with others, from co workers, peers in social situations, to members of a family. Misophonia can be very upsetting not only to the sufferer but to those around them who can become the focus of the rage and frustration involved in a triggered event.
There are things that can be done to address misophonia and to help sufferers cope.

One can use “white noise machines”, a safe space where the sufferer can retreat to avoid the input that upsets us, headphones with music or soothing sounds, some attempts have been made to de-sensitize through longer and longer exposures to the upsetting sounds, and using Biofeedback might help in some cases.
Occupational Therapists may be able to help, depending on their specialties.
Misophonia is rare enough in the general public that many Family Doctors have never heard of it.
If you struggle, you may ask for a referral to a neuro psychologist or other specialists. Please don’t hesitate to reach out to find ways to help and to make self accommodations to protect yourself and those you care about from the effects of misophonia.
