A concussion is a form of a mild traumatic brain injury (TBI). This injury is a result due to a blow to the head that could make the person's physical, cognitive, and emotional behaviors irregular. Symptoms may include clumsiness, fatigue, confusion, nausea, blurry vision, headaches, and others. [7] Mild concussions are associated with sequelae ...
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area.It is common for both focal and diffuse damage to occur as a result of the same event; many traumatic brain injuries have aspects of both focal and diffuse injury.

This is often a result of secondary injury, which can damage neurons that were unharmed in the primary injury. It occurs after a variety of brain injury including subarachnoid hemorrhage, stroke, and traumatic brain injury and involves metabolic cascades. [13] Secondary injury can result from complications of the injury. [1]
A common category with the greatest number of injuries is traumatic brain injury (TBI) following physical trauma or head injury from an outside source, and the term acquired brain injury (ABI) is used in appropriate circles to differentiate brain injuries occurring after birth from injury, from a genetic disorder (GBI), or from a congenital ...
The ICD-10 established a set of diagnostic criteria for PCS in 1992. [38] In order to meet these criteria, a patient has had a head injury "usually sufficiently severe to result in loss of consciousness" [33] [39] and then develop at least three of the eight symptoms marked with a check mark in the table at right under "ICD-10" within four weeks.
[10] [11] Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke. Despite its lack of identifiable symptoms, a silent stroke still causes brain damage and places the patient at increased risk for a major stroke in the future. In a broad study in 1998, more than 11 million ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
