Understanding the complex relationship between traumatic brain injury and mental health — evidence-based insights for survivors, caregivers, and medical professionals.
It is normal to be depressed after a traumatic brain injury. You have lost your life as you know it. You are living with a person you don't recognize — yourself. Your brain is overwhelmed.
That's not a character flaw. That's not weakness. That's a brain that has been injured and is trying to heal. And there is hope.
Progress will not go up in a straight line. It's more like a very wavy line — hills and valleys — that slowly trends upward over time.
⬆️ Good days and bad days are both part of healing. A bad day doesn't mean you're back to the beginning.
Good days and bad days are both part of healing. A bad day doesn't mean you're back to the beginning. It just means today is a valley. The hill will come again.
The hills and valleys aren't random. Certain environments, sounds, lights, people, or demands can trigger valleys — others can help you climb back up.
I created a TBI Log Book to track environmental factors so you can see your patterns and manage your triggers.

Sustainable strategies for ongoing mental health
Depression is common after TBI, but many survivors also experience something else — sudden, uncontrollable emotional outbursts that look like mental illness but aren't.
My take: Emotional seizures aren't mental illness. They're the brain being overwhelmed. I wrote a book about recognizing triggers and managing these episodes — for survivors, families, and caregivers.
