How do I know if I have Acquired Brain Injury (ABI)?

An Acquired Brain Injury (ABI) is defined as any injury to the brain that has occurred after birth, excluding congenital or degenerative conditions, and it is identified through a sudden change in cognitive, physical, or emotional function. If you notice persistent neurological symptoms following an incident or unexplained health decline, you should seek a comprehensive evaluation from a neurologist to determine if an Acquired Brain Injury is the underlying cause.

What are the early signs and symptoms of an Acquired Brain Injury?

Because an Acquired Brain Injury can result from trauma, stroke, hypoxia, or infection, the symptoms are diverse. Patients often report a "foggy" feeling, persistent headaches, or changes in personality. Recognizing an Acquired Brain Injury involves tracking subtle shifts in your daily baseline that do not resolve with rest.

What patterns should I look for in my own health?

To identify an Acquired Brain Injury, look for clusters of symptoms that appear together. You may notice:

• Cognitive changes: Difficulty concentrating, memory lapses, or confusion.


• Physical symptoms: Chronic fatigue, dizziness, sensitivity to light/sound, or balance issues.


• Emotional shifts: Increased irritability, anxiety, or depression that feels "out of character."


• Sleep disturbances: Excessive sleeping or persistent insomnia.

When should I see a doctor and what tests are used?

If these symptoms persist for more than a few weeks, consult a physician. Ask specifically for a referral to a neurologist or neuropsychologist. Diagnostic tools for an Acquired Brain Injury may include neuroimaging (MRI or CT scans) to check for structural damage and cognitive testing to measure executive function and memory. Note that some forms of an Acquired Brain Injury, such as those involving micro-structural damage, may not always appear on standard imaging.

What are the red flags requiring urgent care?

Seek emergency medical attention if you experience seizures, loss of consciousness, repeated vomiting, worsening confusion, or localized weakness in an arm or leg. These could indicate an acute progression of an Acquired Brain Injury.

How can I advocate for myself?

If your concerns are dismissed, document your symptoms in a daily log. Bring a family member or friend to appointments to provide an objective perspective on how your behavior has changed since the potential Acquired Brain Injury occurred.
