I think it’s so important to understand how trauma and ACE’s initiate biological responses. It feels like many avoid it because it’s “complicated”, but the knowledge allows you to work with the person to draw a connection between the trauma and presenting trauma-related symptoms.
Also,if you’re referring someone to a therapy like EMDR, it’s important to know how EMDR works, & to also be aware that it could pose a risk of re-traumatising.Being educated on delayed trauma responses & understanding that triggers can precede traumatic stress reactions are key.

I wrote this because I observed a conversation today at work where a nurse said that PTSD behaviours are caused by a chemical imbalance and it’s not this or this simple!
I love these infographics too.
Have a read about epigenetics. Very very interesting!
