Overview

Major or Mild Neurocognitive Disorder Due to Traumatic Brain Injury

DSM-V Diagnostic Criteria for Major or Mild Neurocognitive Disorder Due To Traumatic Brain Injury^[1]

“

A.The criteria are met for major or mild neurocognitive disorder.

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.Posttraumatic 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

Prevalence

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

Risk Factors

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

Somatic symptom disorder^[1]
