Traumatic brain injuries can disrupt attention, short-term recall, emotional regulation and energy production within neural networks that support daily functioning. Across Australia, approximately 190,000 to 200,000 new cases occur each year, and more than 700,000 people live with ongoing effects nationwide. Many people experience reduced independence and vocational strain following TBI.
TMS for TBI applies repetitive transcranial magnetic stimulation to modulate disrupted cortical circuits without surgery or medication changes. Clinicians offer TMS therapy for TBI to stimulate regions linked to concentration and mood stability, to restore measurable function after injury.
What is Traumatic Brain Injury?
Traumatic brain injury occurs when sudden force disrupts normal brain function, often after motor vehicle accidents, falls, sports collisions or assaults involving head injuries. Damage may stay localised to a single region of the brain.
Rotational acceleration can also shear neural connections and contribute to diffuse axonal injury across multiple brain networks. Clinicians classify severity from mild traumatic brain injury, commonly called concussions, through to moderate and severe TBI, which carry a greater risk of long-term disability.
Primary injury occurs at impact. Secondary changes develop over hours or days following traumatic brain injury, as inflammation and altered cerebral blood flow evolve within vulnerable tissue. Understanding these processes guides the treatment of traumatic brain injury and broader management decisions in rehabilitation settings.
Types and Effects of TBI
Traumatic brain injury presents with distinct structural patterns and a wide range of functional consequences. Injury classification reflects how the brain is damaged, while symptoms reflect which neural systems are disrupted. Clear differentiation supports accurate assessment and targeted rehabilitation planning.
- Closed injury: Brain tissue is damaged without skull penetration, often after motor vehicle accidents or sporting collisions that cause internal movement within the cranial cavity.
- Penetrating injury: An external object breaches the skull, such as in a gunshot wound, producing focal tissue destruction along the object’s path.
Adults may experience confusion, reduced concentration or memory loss that interferes with employment. Motor deficits can limit strength or coordination, and sensory changes may alter visual processing. Communication difficulties sometimes affect speech production or language comprehension, reducing independence in daily life.
Emotional and behavioural changes can also occur. Depression, anxiety, irritability or impulsive behaviour may develop. Post-traumatic epilepsy remains a recognised risk, particularly after injuries involving structural brain damage.
Recovery and Rehabilitation After TBI
Recovery after traumatic brain injury relies on the brain’s capacity for neuroplastic change. Undamaged regions can sometimes reorganise neural pathways and assume functions previously managed by injured tissue, although adaptation differs between individuals. Progress may be gradual and can extend over months or even years.
Rehabilitation commonly includes structured physical therapy to address mobility limitations and muscle weakness. Speech therapy supports language comprehension and verbal expression when communication is affected.
Cognitive rehabilitation targets attention, memory and executive function through task-based training. Psychological support helps manage mood disorders and behavioural changes, while pain management addresses persistent headaches or neuropathic discomfort. Family education also plays an important role in supporting long-term adjustment.
Can TMS Help with Traumatic Brain Injury?
Transcranial magnetic stimulation may complement standard rehabilitation rather than replace established therapies. The use of transcranial magnetic stimulation in traumatic brain injury focuses on targeted neuromodulation to influence disrupted cortical circuits through controlled non-invasive brain stimulation.
Clinicians apply carefully selected stimulation parameters to align treatment with each patient’s neurological profile and recovery stage. Evidence from research includes a scoping review of approximately 30 studies reporting improvements in depressive symptoms, central pain, dizziness and visual neglect after injury.
Cognitive outcomes and disorders of consciousness showed more variable responses. Case data also describe measurable gains in working memory, processing speed and sustained attention after low-frequency repetitive stimulation in a young adult with severe injury.
How TMS May Help After TBI
After traumatic brain injury, targeted neuromodulation aims to adjust cortical excitability and support adaptive reorganisation within disrupted brain networks. The objective is to recalibrate function within affected areas of the brain.
Transcranial magnetic stimulation in clinical settings delivers a rapidly changing magnetic field that generates focal currents in superficial cortical regions, unlike electrical stimulation, which applies direct current through surface electrodes.
Researchers continue examining how stimulation of the human motor cortex, among other regions, may influence broader connectivity beyond primary motor pathways.
Areas currently being explored in rehabilitation include:
- Attention problems: TMS may help improve sustained focus and working memory.
- Mood changes: Depression symptoms, anxiety and emotional instability may improve.
- Post-concussion symptoms: Possible relief from headaches, dizziness and concentration problems.
Results vary between individuals, and TMS may not produce the same level of benefit for everyone.
Are there Risks or Side Effects of TMS After TBI?
TMS treatment is generally considered low risk, and most people tolerate it well, including many TBI patients. Reported side effects are usually mild and short-lived.
Some individuals notice scalp discomfort, headache, facial twitching or light-headedness during or shortly after sessions. Rare effects include temporary hearing changes without ear protection, brief mood shifts or short periods of confusion.
TMS is not suitable for everyone. People with a history of epilepsy or seizures, or those with ferrous (magnetic) metal implants in the head or neck area, are generally not candidates for TMS. A thorough individual assessment is conducted prior to commencing treatment to confirm suitability.
What to Expect From a TMS Course
A course of TMS treatment follows a structured format delivered in an outpatient setting. Most people tolerate sessions well and remain awake throughout. What you can expect during treatment includes:
- Initial setup and mapping: The first appointment lasts about 60 to 90 minutes, during which a technician identifies the correct coil position and determines the motor threshold.
- Sensory experience: You will hear clicking sounds and feel a tapping sensation on the scalp that may resemble light knocking and can feel unusual at first.
- Comfort and activity: You sit in a reclining chair and may watch television, listen to music or speak with the technician during the session.
- Session duration: Standard TMS appointments usually last for approximately 20 minutes, while some accelerated TMS protocols are shorter.
Clinicians monitor progress to evaluate when stimulation improves functional outcomes and may discuss how TMS compares with other brain stimulation techniques, including transcranial direct current stimulation, where appropriate for TBI patients.
Is TMS Right for You?
You may be a suitable candidate for TMS treatment for TBI if ongoing symptoms continue to interfere with recovery and overall quality of life despite appropriate care.
- Persistent mood symptoms: Ongoing depression, anxiety or irritability that has not responded adequately to rehabilitation or medication.
- Cognitive difficulties: Attention deficits, executive dysfunction or slowed processing affecting daily tasks.
- Mental health diagnosis: Confirmed major depressive disorder contributing to functional impairment.
- Medical suitability: Specialist assessment confirms no contraindications, with careful consideration of seizure risk and structural brain changes.
Neuralia TMS offers TMS as a non-invasive brain stimulation option for people living with traumatic brain injury. Suitability is assessed on a case-by-case basis, taking into account injury history, current symptoms, and treatment goals. Treatment is usually organised into a block of outpatient sessions over several weeks, with flexibility where clinically appropriate.
Our clinicians periodically review changes in symptoms and may adjust stimulation settings or session plans as indicated. TMS is integrated with ongoing medical, psychological, and rehabilitation support, thereby complementing rather than replacing other therapies.

TMS for TBI FAQs
How long do the benefits of TMS usually last after a course of treatment?
Benefits often last several months and may extend longer for some people. Duration varies by individual, and occasional booster sessions may help sustain improvement as symptoms return.
How many TMS sessions are usually needed before noticing a change?
Most treatment courses involve approximately 20 to 35 sessions delivered over four to six weeks. Many people who respond begin noticing gradual improvements within the first two to four weeks.
Will I still need medication or rehabilitation therapy if I start TMS?
TMS is generally used alongside existing treatments such as medication, psychotherapy or rehabilitation. Your clinical team may adjust your broader care plan depending on your response and overall progress.
