Overview[edit | edit source]

Major or Mild Neurocognitive Disorder Due to Traumatic Brain Injury[edit | edit source]

DSM-V Diagnostic Criteria for Major or Mild Neurocognitive Disorder Due To Traumatic Brain Injury[edit | edit source]

• A. The criteria are met for major or mild neurocognitive disorder.^[1]

AND

• B. There is evidence of a traumatic brain injury—that is, an impact to the head or other mechanisms of rapid movement or displacement of the brain within the skull, with one or more of the following:

• 1.Loss of consciousness.

• 2.Post-traumatic amnesia.

• 3.Disorientation and confusion.

• 4.Neurological signs (e.g., neuro imaging demonstrating injury; a new onset of seizures; a marked worsening of a preexisting seizure disorder; visual field cuts; anosmia; hemiparesis).

AND

• C. The neurocognitive disorder presents immediately after the occurrence of the traumatic brain injury or immediately after recovery of consciousness and persists past the

acute post-injury period.

Epidemiology and Demographics[edit | edit source]

Prevalence[edit | edit source]

The prevalence of traumatic brain injury is 59,000 per 100,000 (59%) in males in the overall population.^[1]

Risk Factors[edit | edit source]

• Low Glasgow Coma Scale score
• Midline shift
• Obliteration of third ventricle
• Older age (older than 40 years)
• Petechial hemorrhages
• Pupillary non reactivity
• Repeated concussions
• Subarachnoid hemorrhage
• Worse motor function^[1]

Differential Diagnosis[edit | edit source]

• Factitious disorder
• Posttraumatic stress disorder

• Somatic symptom disorder^[1]
