Spotlight on Head trauma: neurobehavioral aspects

In this clinical summary, Dr. Alfredo Ardila of Florida International University discusses the neurobehavioral aspects of head trauma. Traumatic brain injury and its consequences became an epidemic, primarily due to the widespread use of motor vehicles. The specific neurobehavioral aspects of traumatic brain injury include (1) acute concussional syndrome, (2) the postconcussional disorder, (3) diffuse traumatic brain injury, (4) focal traumatic brain injury, (5) secondary complications of acute traumatic brain injury, (6) delayed deterioration, (7) posttraumatic dementia, and (8) posttraumatic neuropsychiatric disorders. Even mild head injury may result in cognitive consequences. Patients with mild head injury demonstrate deficits in attention, nonverbal fluency, and verbal memory. Long-term cerebral atrophy has been correlated with injury severity and duration of posttraumatic amnesia. Impairments can be found in different cognitive measures many years after the injury.

Spotlight on Traumatic cranial neuropathy

Traumatic cranial neuropathies are often seen with fractures involving the skull base. They most frequently involve the olfactory and optic nerves at the anterior skull base or the seventh and eighth cranial nerves in the temporal bone. In this updated clinical summary, Dr. Richard Polin of George Washington University adds epidemiological and incidence data on traumatic cranial neuropathy.

Spotlight on Headache attributed to head trauma

Headache is common following head injury. Most individuals recover within days, weeks, or months, but a minority of subjects may suffer from intractable posttraumatic headache despite treatment. Posttraumatic headache remains a subject of controversy over the years concerning its pathophysiology. Litigation and medicolegal problems further complicate this issue. In this clinical summary, Dr. Kai-Chen Wang of Cheng Hsin General Hospital in Taiwan summarizes current understanding of posttraumatic headache, including a brief historical review of the disease, the classification and diagnostic criteria, the epidemiology, clinical manifestations, pathophysiology, diagnostic evaluation, and management.
