Two main areas of the brain associated with memory are the medial temporal lobe, which houses the hippocampus and is thought to be responsible for consolidating new information into long-term memory, and the pre-frontal cortex, which has been found to be related to attention and short-term memory. In mild traumatic brain injury, one of the most [...]

Symptoms of mild traumatic brain injury, such as sleep disorders, memory impairment or attention problems, can overlap symptoms of depression. In the forensic setting, the distinction between symptoms of mTBI and depression is a critical one, but diagnostic mistakes can easily be made. Recently, a study comparing mTBI patients with depression, mTBI patients without depression, and [...]

A common feature of mild traumatic brain injury is damage to the white matter tracts that connect one part of the brain to another, or diffuse axonal injury (DAI). DAI is difficult to see in the traditional CT or MRI scans, and while it can be detected using newer technology such as diffusion tensor imaging, [...]

S100B is a type of protein found in neurons, as well as other cells outside of the brain. Its role seems to depend on its concentration. Low levels of S100B are found in healthy brains, indicating a supportive role when in low quantity. Levels of S100B rise considerably after brain injury, and may involve a [...]

Children who suffer from mild traumatic brain injury are often referred back to their primary pediatrician for follow-up care. A recent study found that 89% of pediatricians felt that they were the appropriate care provider for the follow-up of mTBI, however 59% of these did not participate in continuing education to learn more about TBI [...]

Recent studies have shown that the pituitary gland is particularly susceptible to traumatic brain injury. Since the pituitary gland is responsible for hormone release, hormone deficiency is a common problem in brain injury survivors. Growth hormone deficiency is the most common hormone deficiency found after TBI, regardless of severity. Growth hormone deficiency is related to muscle [...]

Although it is not completely understood why, cases of mild traumatic brain injury are more often associated with new-onset depression than those of moderate or severe traumatic brain injuries. Studies have shown that rates of depression prior to injury are associated with rates of depression after injury, but the risk factors for those who have [...]

It is generally acknowledged that antipsychotic drugs can slow cognitive and motor recovery in patients with traumatic brain injury. Recent studies have shown that antipsychotic use is also associated with an increased risk of sudden cardiac death and stroke.

Traumatic Axonal injury associated with mild traumatic brain injury can be either hemorrhagic or non-hemorrhagic. While the axons themselves do not necessarily bleed when torn, small vessels in the vicinity may. The below article discusses the utility of CT scan as it applies to outcome and predictive outcome in mTBI. The authors confirm that other [...]
