Many people consider misophonia a condition that is the same for everyone. It is true that there is a group of common triggers (such as eating sounds) and common emotional reactions (anger, hatred, rage, and disgust). It often starts during the late childhood years (six to twelve) and becomes much worse in the teen years. But within this apparently uniform condition there is much variation. What are the differences from person to person that we see? We can identify diversity in four areas:
1. The age of onset.
2. When it becomes severe.
3. Trigger sounds (especially the first trigger).
4. Initial physical reflexes.
