Brain Injury Overview
Traumatic Brain Injury (TBI) can negatively impact numerous physical skills and mental well-being. Physical traits that can be affected include mobility, sense of balance, dexterity, fine motor skills, vigor, and stamina. Cognitive deficiencies in terms of speaking and communication ability, mental capacity, recollection, and perceptiveness are common. Mental status often changes, and victims sometimes experience difficulty coping with newfound disabilities.
Brain injury can occur a number of different ways. Traumatic brain injuries usually follow in the wake of an accident in which the victim’s head collides with another object. This sort of violent impact is the most common cause of TBI, but other injuries triggered by lack of oxygen, exposure to toxins, or a virus can produce similar results.
Someone who suffers a Mild Traumatic Brain Injury (MTBI) may experience temporary unconsciousness, memory loss concerning the events leading up to or immediately following the injury, mental instability, or central nervous system deficiencies. MTBI patients typically appear fine on the outside, but chronic functional problems persist. When some victims experience long-term consequences of MTBI, it is called postconcussion syndrome (PCS). PCS can bring about drastic changes in awareness and behavior.
The majority of traumatic brain injuries cause extensive harm to the brain because it jiggles around inside the skull upon impact. A diffuse axonal injury takes place when the nerve cells are separated from one another. Damage confined to a tiny area also occurs when the brain smashes into the wall of the skull. This can be potentially dangerous to the brain stem, frontal lobe, and temporal lobes due to their close proximity to jagged bones.
The brain stem, situated at the brain’s base, controls rudimentary arousal and regulatory tasks and also plays a role in attention span and short-term memory. Shock to this area can result in confusion, aggravation, and rage. The limbic system, which is above the brain stem, helps manage emotion. The temporal lobes, which are linked to the limbic system, take part in a variety of cognitive skills like memory and speech. Injury to the temporal lobes, or convulsions in this region, has been connected to numerous behavioral irregularities. Because of its substantial size and placement towards the front of the cranium, the frontal lobe is almost always injured in accidents involving brain injury. The frontal lobe is involved in many cerebral behaviors and is viewed as the emotional and personality traits command center. Damage to this section of the brain can worsen decision-making skills and increase unpredictable conduct.
