3 Things People Get Wrong About Brain Injury By Youlan Li

Myth 1: You have to lose consciousness to have a brain injury

Many people think that if you didn’t black out or fall unconscious, you couldn’t have a brain injury. But that’s not true. You can hit your head or experience a jolt and still damage your brain, even if you stay awake the whole time. In fact, lots of concussions don’t involve any loss of consciousness at all (American Association for Neurological Surgeons, 2024). Just because someone didn’t pass out doesn’t mean they are okay. Symptoms can show up hours or even days later, including headaches, confusion, dizziness, or memory problems. Anyone who experiences a head injury should be monitored for symptoms, regardless of whether they lost consciousness.

Myth 2: If your MRI and/or CT scan is normal, you’re fine

Another common myth is that a brain scan like an MRI or CT can always show if you have a brain injury. But these scans usually only pick up serious injuries like bleeding or swelling. Mild injuries, like concussions, which involve metabolic and microscopic changes in brain function, often don’t show up at all (UVA Health). That doesn’t mean the person is faking or imagining their symptoms. They can still have real problems with thinking, feeling, or remembering, even if their scan looks normal. That’s why doctors also look at symptoms and behavior, not just images.

Myth 3: People with brain injuries don’t know what’s going on

It’s a harmful myth that people with brain injuries don’t understand what’s happening around them. While some injuries can affect memory or thinking, that doesn’t mean someone can’t have thoughts, feelings, or preferences. Many people with brain injuries are aware of their surroundings and want to be part of decisions about their lives and care. They may just need more time to process information or express themselves. It’s important to treat them with respect and include them in conversations.
