Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.

Memory and new learning involve the cerebral cortex, the subcortical projections, the hippocampus, the diencephalon and the thalamus, areas that often experience damage as a result of TBI. Frontal lobe lesions may also play a role in PTA, as damage to these areas is associated with changes in behavior, including irritability, aggressiveness ...
Amnesic patients with damage to the hippocampus are able to demonstrate some degree of unimpaired semantic memory, despite a loss of episodic memory, due to spared parahippocampal cortex. [38] In other words, retrograde amnesics "know" about information or skill, but cannot "remember" how they do.
Head injury is a broader category that may involve damage to other structures such as the scalp and skull. TBI can result in physical, cognitive, social, emotional and behavioral symptoms, and outcomes can range from complete recovery to permanent disability or death. Causes include falls, vehicle collisions and violence. Brain trauma occurs as ...
When people experience physical trauma, such as a head injury in a car accident, it can result in effects on their memory. The most common form of memory disturbance in cases of severe injuries or perceived physical distress due to a traumatic event is post-traumatic stress disorder, [3] discussed in depth later in the article.
Headaches and pain can occur as a result of a brain injury, either directly from the damage or due to neurological conditions stemming from the injury. Due to the changes in the brain as well as the issues associated with the change in physical and mental capacity, depression and low self-esteem are common side effects that can be treated with ...
The hippocampus is the brain region located in the medial temporal lobe, responsible for forming new episodic and semantic memories. As a result of his neurological damage, Cochrane suffered severe cognitive deficits that hindered his ability to form new episodic memories. However, both his semantic memory and noetic consciousness remained ...
Post-traumatic epilepsy (PTE) is a form of acquired epilepsy that results from brain damage caused by physical trauma to the brain (traumatic brain injury, abbreviated TBI). [1] A person with PTE experiences repeated post-traumatic seizures (PTS, seizures that result from TBI) more than a week after the initial injury. [2]
