A study by researchers in the Netherlands has found that misophonia shares genes with mood disorders such as anxiety, depression, and PTSD. The University of Amsterdam psychiatrist Dirk Smit and colleagues analyzed genetic data from the Psychiatric Genomics Consortium, UK Biobank, and 23andMe databases. They found that those with misophoni were more likely to have genes associated with psychiatric disorders, as well as tinnitus. This overlap with PTSD genetics could suggest a shared neurobiological system that affects both conditions. The study also indicated that people with autism spectrum disorder (ASD) were less likely to experience misophonian, which was unexpected as those with ASD often have decreased ability to tolerate sounds. However, the study also highlighted potential forms of this disorder driven by anger or other negative emotionality to trigger trigger sounds.
