Head injury alters mental or physical function due to a blow to the head.
Head injury severity is classified using the Glasgow Coma Scale (GCS) score based on eye, motor, and verbal responses.
Scores of 13–15 denote mild injury, 9–12 moderate, and 8 or less severe injury. Some studies classify scores of 13 as moderate, while only 14 or 15 are considered mild.
Head injury involves trauma to scalp, skull, and brain. Head injuries vary in severity, from minor bruises to serious brain damage.
These efforts highlight the condition’s complexity and encourage researchers and physicians to reject oversimplifications.
This review focuses on recent advancements in adult closed head injury management.
Types of Head Injuries are:
Concussion
Contusion
Skull Fractures
Epidural Hematoma
Subdural Hematoma
Intracerebral Hemorrhage
Diffuse Axonal Injury
Epidemiology
In 2003, elderly with head injuries had increased hospitalizations and deaths. Head injury data comparison internationally is challenging due to diagnostic inconsistencies.
Some individuals with cognitive and emotional issues from mild head injury may fail to connect their injury to its consequences.
A study from Charlotte revealed minority status significantly predicted intentional head injury to control for demographic factors.
American Indian/Alaska Native individuals experience higher TBI hospitalizations and deaths than others. About half of head injury patients are 24 years old or younger.
Elderly over 84 years have over three times higher emergency room visit rates for head injuries than those aged 65-74.
Anatomy
Pathophysiology
The skull can fracture linearly or in a complicated depressed manner with bone fragments beneath the surface.
Direct impact and contrecoup injuries can cause focal bleeding beneath the skull due to brain movement.
Chronic subdural hematomas are viewed as neoplastic processes initiated by injuries to dural cells.
Failures have led to complex models of neuronal injury and cell death development. Head injury often shows clear structural changes in autopsy imaging.
Head injury triggers free radical release and membrane lipid breakdown with elevated plasma metabolites related to fatty acid and lipid breakdown.
Etiology
The causes of head injury are:
Sports Injuries
Assaults
Road Traffic Accidents
Falls
Workplace Injuries
Genetics
Prognostic Factors
High-impact trauma worsens prognosis versus low-impact injuries.
Severe head injury mortality rate in adults is 25% to 36% within six months.
A 2022 study found 21% had death outcomes after 6 months. 5.6% of mild head-injured patients had unfavourable outcomes.
Researchers warned their findings might not apply universally, as sicker patients could have had care withdrawn or lacked rehabilitation eligibility.
A study of severely head-injured elderly Norwegians found 72% had unfavourable outcomes to dependence outside their home environment.

Acuity of presentation
Acute symptoms are:
Loss of consciousness, headache, vomiting, seizures, pupil abnormalities, altered mental status
Emergency procedures include airway management while surgical interventions include craniotomy, hematoma evacuation and decompressive craniectomy.

In prehospital phase, the focus is to prevent secondary brain injury and stabilize the patient for safe transport to a hospital.
In the emergency department phase, physicians should identify life-threatening conditions and determine the urgent interventions.
Pharmacologic therapy is effective in the treatment phase as it includes the use of osmotic diuretics, anticonvulsants, electrolytes, barbiturates, calcium channel blocker, stimulants, and selective serotonin reuptake inhibitors.
In supportive care and management phase, patients should receive required attention such as lifestyle modification and surgical interventional therapies.
The regular follow-up visits with the neurologist are scheduled to check the improvement of patients along with treatment response.

Acute symptoms are:
Loss of consciousness, headache, vomiting, seizures, pupil abnormalities, altered mental status
Prioritize airway and circulation assessment in acute head injury cases.
A study found higher mortality rates in patients intubated in the field compared to those intubated in hospitals.
Hypertonic saline may lower ICP instead of mannitol, but a meta-analysis showed no mortality reduction or ICP improvement.
High-dose barbiturate therapy is allowed for ICP if conventional treatments fail, despite no proven outcome benefits.
Brain Trauma Foundation recommends ICP monitoring in severe TBIs, with evidence level IIb.
A review indicated early prophylaxis with enoxaparin or heparin is safe shows no difference in intracranial hemorrhage progression.
Steroid-induced hyperglycemia negatively affects outcomes in head-injured patients.
A trial found a trend toward increased mortality with valproate for early seizure prevention.
A study of 9000 patients showed reduced early mortality in mild head injuries with tranexamic acid.
Brain injury increases mitochondrial permeability causes calcium loss and cell death.
Botulinum toxin may reduce hypertonia in head injury patients to enhance passive range of motion.
Neurology
Nasogastric feedings may be necessary for patients with severe head injuries and consciousness issues.
Monitor protein stores and electrolyte balance during treatment phase.
Individualized recommendations for motoric and cognitive recovery needed.

Randomly assigning independent elderly patients to strength and balance training decreased fall frequency and severity.
Proper awareness about head injury should be provided and its related causes with management strategies.
Appointments with neurologist and preventing recurrence of disorder is an ongoing life-long effort.
