Ischemia is one of the leading causes of secondary brain damage after head trauma. [9] Similar mechanisms are involved in secondary injury after ischemia, trauma, and injuries resulting when a person does not get enough oxygen. [5] After stroke, an ischemic cascade, a set of biochemical cascades takes place.
Even a mild incident can have long-term effects or cause symptoms to appear years later. [5] Studies show there is a correlation between brain lesion and language, speech, and category-specific disorders. Wernicke's aphasia is associated with anomia, unknowingly making up words , and problems with
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.

Causes of TBI fatalities in the US [168] TBI is a leading cause of death and disability around the globe [8] and presents a major worldwide social, economic, and health problem. [10] It is the number one cause of coma, [169] it plays the leading role in disability due to trauma, [76] and is the leading cause of brain damage in children and ...
The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, cardiorespiratory arrest, and irreversible brain damage.
Neurogenic shock can result from severe central nervous system damage (brain injury, cervical or high thoracic spinal cord). [1]In simple terms, the trauma causes a sudden loss of background SNS stimulation to the blood vessels.
If the impact causes the head to move, the injury may be worsened, because the brain may ricochet inside the skull causing additional impacts, or the brain may stay relatively still (due to inertia) but be hit by the moving skull (both are contrecoup injuries). Specific problems after head injury can include [4] [5] [6]
A stroke is an interruption of the blood supply to the brain. Approximately every 40 seconds, someone in the US has a stroke. [7] This can happen when a blood vessel is blocked by a blood clot or when a blood vessel ruptures, causing blood to leak to the brain. If the brain cannot get enough oxygen and blood, brain cells can die, leading to ...
