What is an Acquired Brain Injury (ABI)?
ABI means brain damage occurring anytime after birth due to diverse factors. It differs from intellectual disabilities or mental health conditions and can create a range of challenges for those impacted.
What Causes an ABI?
Common triggers include:
Head trauma (also known as traumatic brain injury) or head injuries
Stroke
Drugs, alcohol, or poisons
Prolonged lack of oxygen to the brain (e.g., near-drowning)
Infections
Brain tumors
Progressive conditions like Parkinson's, Alzheimer's, or other dementias
What are the Symptoms of an ABI?
ABI affects individuals differently. Here are the common symptoms:
Physical Signs
Weakness, tremors, rigidity, or balance issues
Fatigue
Altered sleep
Seizures
Headaches
Sensory changes in vision, smell, or touch
Emergency
Seek emergency help (call an ambulance) for head injury cases with altered consciousness, like slurred speech, seizures, or unresponsiveness.
Cognitive Changes
Memory difficulties
Trouble focusing or paying attention
Challenges with planning or organizing
Confusion
Communication struggles, like sustaining conversations
Behavioral or Emotional Issues
Mood fluctuations
Irritability
Personality shifts
How is an ABI Diagnosed?
Diagnosis often starts with brain scans to evaluate damage extent. Additional tests may assess memory, cognition, and daily skills, helping identify issues and required support.
When Should I See My Doctor?
Consult a doctor promptly if ABI symptoms appear. Use the Service Finder for doctors, pharmacies, hospitals, and more.
How is an ABI Treated?
Treatment targets the underlying cause, plus rehab tailored to specific deficits in daily life. Rehab is gradual—most gains occur early on, but progress can span years. Some effects may be permanent.
Living with an ABI
Recovery goals might include skill regain, work, or study return, which can be tough. Prioritize health to aid brain healing. A National Assistance Card helps in emergencies or daily needs.
How Do I Care for a Person with an ABI?
ABI impacts families and caregivers too. You provide vital support but often neglect your own needs, handling home and finances alone, which can feel overwhelming.
