A traumatic brain injury ("TBI") occurs when the brain is somehow injured, shocked, or injured by an external source of force. The modes of acquisition and severity of TBIs are unique to each patient; therefore, symptoms and rehabilitation can vary greatly depending on the patient's condition following the accident and how they sustained the injury. The severity of a TBI is generally classified into one of three categories: mild, moderate, or severe, and these types of diagnostic criteria influence how a TBI patient is treated by medical personnel and rehabilitation specialists. TBIs can affect a specific part of the brain that has been directly affected, leaving patients with only one or a few areas of damage, or the damage can be more widespread across a larger area of ​​the brain, leading to a greater degree of disability overall. . Any person who experiences a large enough force on their skull can get a head injury, whether it's a soldier who suffered combat-related trauma near an explosion, or a child who was shaken (commonly called " shaken baby syndrome"), or survivor of a serious car accident. Impairments and recovery, both short- and long-term, can also vary depending on the age of the patient when they suffered the injury. In a research study that aimed to explore the main causes of traumatic brain injury, individuals were evaluated and assigned to three different groups based on how they acquired the injury (Majdan et al. 798). The study had two main objectives: 1) to determine which type of injury resulted in the highest degree of disability and 2) to determine which group achieved the best recovery outcomes. Participants were… middle of paper… additional factors of cause, severity, and specific area of ​​injury. Retraining the brain to perform previously mastered tasks, such as language and self-care tasks, presents both functional and emotional challenges for children and adults, and the effects of both types of impairments can be equally challenging and discouraging. Even after a ten-year period of recovery progression, the ramifications of traumatic brain injury can still persist in both the physical and psychological domains. Adequate medical, psychological, and social support from physicians, therapists, counselors, families, and colleagues all play an essential integrative role in the overall well-being of traumatic brain injury survivors. Therefore, continued study and growing understanding of this complex condition is vital in both the fields of psychology and medicine.
