Imaging Tools To Assess Mild Brain Trauma

A variety of test are available to assess and diagnosis traumatic brain injury. As technology progresses, new tools are being developed to better assess the structure and function of the brain. The following is a concise discussion on various tools available with their strengths and limitations.

Traumatic Brain Injury and the Increased Risk for Alzheimer's Disease
Author: Richard H. Adler
 
The possibility a traumatic brain/head injury with loss of consciousness presents a potential risk factor for Alzheimer's Disease (AD) has now been studied. It had previously been suggested traumatic brain injury created a heightened risk among carriers of a certain gene type for developing AD. That suggested casual link was affirmed by a study published in Neurology1 that evaluated the relationship between head injury and Alzheimer's Disease. This paper is often referred to as the MIRAGE study (Multi-Institutional Research in Alzheimer Genetic Epidemiology).

Traumatic Head Injury and Long Term Risk of Depression
Author: John R. Alexander
 
Of particular concern to care providers evaluating and treating patients injured in auto accidents is the possibility of head injury. Most individuals who sustain a traumatic head injury diagnosed as a mild concussion will experience no sequelae beyond nine months after the injury incident. That is not always the case however. A study recently published in Archives of General Psychiatry contains significant findings on the incidence of long term depression experienced by men who sustained a head injury in their late teens to early twenties.*

Head Injury Assessement
Author: Richard H. Adler
 
Complaints of post-concussion symptoms and head injury are common among populations of auto accident and other trauma victims, particularly during the acute phase of injury. Symptoms frequently involve reports of memory and attention deficit, headaches with and without nausea, double vision, loss of concentration, increase sensitivity to distractions, anger and/or irritability, apathy, etc..

Mild Brain Trauma and Working Memory
Author: Richard H. Adler
 
It is common for researchers and practitioners to encounter mild traumatic brain injury (MTBI) patients with normal CT or MRI scans, who experience a number of post-concussive complaints and cognitive deficits. A recent study (McAlister TW, Saykin AJ, et al. "Brain Activation During Working Memory One Month After Mild Traumatic Brain Injury" Neurology 1999; 531:1300-1308) deals with the concepts of "working memory" and "processing load."

Chronic Back Pain and It's Relationship to Brain Matter Loss
Author: Richard H. Adler
 
The relationship between the brain and chronic pain is not well understood. However, a 2004 study published in The Journal of Neuroscience begins to shed light on this issue. The study compared the brain morphology of 26 chronic back pain patients to control subjects using MRI brain scans.
