Understanding the Brain

What is a Traumatic Brain Injury?

Written gently, for mothers and families. Anyone can experience a traumatic brain injury — and every person deserves to understand what is happening inside their loved one's brain.

Definition

A Traumatic Brain Injury, gently explained.

A Traumatic Brain Injury — or TBI — happens when a sudden bump, blow, jolt, or penetrating force disrupts the normal function of the brain.

Some brain injuries are visible on imaging. Many are not. Some heal quickly. Others require months, years, or a lifetime of care and adaptation.

No two brain injuries are alike. No two recoveries look the same.

Types of TBI

Every diagnosis matters.

Mild / Concussion

Brief or no loss of consciousness. Headache, dizziness, brain fog. Most recover in weeks, though some develop persistent symptoms.

Moderate

Loss of consciousness approximately 15 minutes to 4 hours. Significant confusion. Often abnormal imaging. Rehabilitation frequently required.

Severe

Loss of consciousness greater than 4 hours. Coma or disorders of consciousness. Significant bleeding or swelling. Long-term rehabilitation and support often required.

Penetrating

An object pierces the skull and enters the brain. Immediate emergency care is required.

Common Causes

Anyone can experience a TBI.

  • FallsThe leading cause of TBI across all age groups.
  • Motor Vehicle AccidentsSudden impact, whiplash, or airbag deployment can injure the brain.
  • SportsFootball, soccer, cycling, and contact sports carry concussion risk.
  • ViolencePhysical assault, gunshot wounds, and domestic violence.
  • Military ServiceBlast injuries and combat-related trauma.
  • AssaultAny blow to the head from another person.
  • Work InjuriesConstruction, industrial, and workplace accidents.
  • Intimate Bedroom AccidentsHead injuries can occur during intimacy when the head strikes a headboard, wall, floor, or another object. Any blow to the head should be taken seriously if symptoms develop.
Common Symptoms

Symptoms vary. Compassion should not.

No two brain injuries are exactly alike. A survivor may experience only a few of these symptoms — or many of them. Symptoms can also change from day to day.

Recovery

Healing takes time. Hope is not a timeline.

Recovery from a brain injury is rarely linear. There are days of leaping progress and weeks that feel unchanged. Both are part of the story.
