Traumatic Brain Injury: Symptoms, Diagnosis & Treatment
A clear, clinically structured guide to traumatic brain injury (head injury), covering warning signs, diagnosis and emergency treatment.
Treatment usually begins with
Specialist Assessment
Diagnostic Imaging
Medical Management
Care Team Follow-up
Your neurology team will confirm the right diagnostic and treatment pathway based on your symptoms and imaging findings.
You may need this evaluated if...
A traumatic brain injury needs emergency evaluation if there is:
- Loss of consciousness, even briefly, after a head injury
- Repeated vomiting or worsening headache after trauma
- Confusion, slurred speech or unequal pupils
- A seizure following a head injury
Any head injury with loss of consciousness or worsening symptoms is a medical emergency, seek care immediately.
What is Traumatic Brain Injury?
A traumatic brain injury (TBI) occurs when a blow, jolt or penetrating injury disrupts normal brain function. Severity ranges from a mild concussion to severe injury requiring emergency surgery.
Ranges in Severity
TBI spans from a mild concussion to severe brain injury.
Time-Critical
Prompt assessment after a head injury helps prevent complications.
Imaging Guides Care
A CT scan quickly identifies bleeding or swelling in the brain.
Recovery is Possible
Structured rehabilitation supports recovery after moderate to severe injury.
Common Symptoms
- Loss of consciousness after a head injury
- Persistent headache after trauma
- Confusion, memory problems or slurred speech
- Repeated vomiting or worsening nausea
- One pupil larger than the other
- Weakness, numbness or seizures after injury
What Increases Your Risk
A combination of medical, lifestyle and hereditary factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
1. Rapid clinical assessment
Checking consciousness level, pupils and neurological function immediately after injury.
2. CT scan of the brain
Emergency imaging to detect bleeding, swelling or skull fracture.
3. Ongoing monitoring
Repeat assessment tracks for delayed complications after significant head injury.
Treatment Approaches
Medical Care
- Close Neurological Monitoring
- Rest and Gradual Return to Activity
- Medication for Headache or Seizures
- Structured Rehabilitation
Surgical Care
When imaging shows significant bleeding, swelling or a skull fracture, emergency surgery may be needed to relieve pressure on the brain.
Treatment decisions are based on symptoms, imaging, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- A minor bump to the head with no loss of consciousness
- Mild, improving symptoms after a day or two
- You want a check-up after a past head injury
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Loss of consciousness after a head injury
- Repeated vomiting, worsening headache or confusion
- A seizure or unequal pupils after trauma
