A brain injury is an injury to the head which causes damage to the brain. It can occur in two ways. It can be a penetrating head injury or a closed one. Where penetration occurs, the skull is pierced and a piece of the bone from the skull gets into the brain tissue. In the case of a closed injury, there is no break in the skull. It can affect one or more areas of the brain. Below is a report on brain injury, symptoms, effects so as to create awareness on the issue.
Brain injury may cause mild initial symptoms or immediately life-threatening damages depending on the mechanism and severity of the brain injury. The common symptom of a brain injury is the loss of consciousness. This may be short or prolonged. It varies from person to person. The most severe symptoms of brain injuries are seizures and dizziness. Extreme headaches are another symptom. Long headaches might require a person to go to a doctor. Nausea and vomiting also indicate injuries to the brain. Someone who experiences blurred vision may be suffering from a brain injury. Memory loss is the other symptom. It may be long or short term. Other symptoms that may not be quick to detect are irritability, balance problems, and behavioral changes. The symptoms that are present is dependent on the extent of the injury and which part of the brain is injured. At times it may be difficult to figure out symptoms related to head injury and symptoms which arise from other factors that may be affecting a person. For example, loss of employment, use of medications, ongoing legal issues, financial problems, personal relationship issues and other health problems.
The brain is the most integral part of the human body. Any injuries to it may lead to severe consequences. Effects of brain injury depend highly on the part of the brain which is damaged.
The various parts of the brain are highlighted below and the effects that may arise if any of them is damaged:
The Frontal Lobe
This area of the brain is closely associated with cognitive thought. It aids in the rationalization of ideas, making decisions and predicting the consequences of actions. Operating within the limits of socially acceptable behavior and maintaining one’s inhibitions are the most important social controls of the frontal lobe, and it also plays a significant role in holding long-term memories. Effects of damages to it are: paralysis, inability to think flexibly, social behavior changes and decreased spontaneity in interactions with others.
The Parietal Lobe
This is the center of quantitative thinking and sensory perception. Damage to this area causes difficulties with reading, writing, or inability to generate required words. It also causes problems with hand-eye coordination, as well as problems distinguishing left from right.
The Occipital Lobe
This is the center for visual processing in the brain. It not only controls color recognition and vision. Effects to this part, when injured, are difficulty recognizing objects and colors, challenges when reading and writing and problems with visual illusions or hallucination appearances.
Other effects arising from brain injuries may include costs of treatment, alienation from others and strain on relationships such marriages.
