Brain bruises can have lasting effects, including post-concussion syndrome, nerve damage, and behavioral changes. Prompt treatment is important to prevent complications and reduce the risk of permanent damage. A coup injury can cause widespread cognitive symptoms. Bleeding in the brain tissues can lead to lasting effects, such as altered consciousness, seizures, headaches, and memory loss. Post-concussion syndrome can last for weeks to months, and medical imaging may be needed to locate damage.
Brain bruises, also known as brain contusions, can have lasting effects for hours, days, weeks and months after an initial injury due to damage to brain tissue. This can include post-concussion syndrome, nerve damage, and behavioral changes, among other effects. It is important that people who experience blows to the head receive prompt treatment for brain injuries, as some complications can be prevented, reduced, or eliminated with treatment. If someone suffers a blow to the head, a neurologist should conduct an evaluation, even if the patient appears to be fine, as it can take hours for brain damage to occur.
It is common for people with brain bruises to have what is known as a coup injury. In this type of head injury, there is bruising and damage at an initial point of impact, such as the area of a skull that collided with a steering wheel in an accident. There is also corresponding damage to the opposite side of the skull, caused by the brain slamming into the skull after it rebounds from the initial point of impact. This can lead to widespread cognitive symptoms as two areas of the brain are involved.
When the brain is injured, bleeding occurs in the brain tissues. This puts pressure on the tissue, as there is limited room for expansion within the skull. Tissues within the brain can be injured or killed, with damage developing over hours or days. A cascade of chemical reactions takes place within the brain, leading to lasting effects after injury. Prompt treatment can address some of these problems and reduce the risk of permanent damage.
After brain bruise injuries, people may experience an altered level of consciousness, seizures, headaches, behavior changes, numbness and tingling in the nerves, memory loss, confusion, learning disabilities, and other cognitive disabilities. Some of these changes may resolve as the patient recovers. In other cases, they can become permanent. Sometimes, they start well after the injury; the patient may initially feel healthy, but as the damage progresses within the skull, the patient develops neurological symptoms.
In post-concussion syndrome, people experience concussion symptoms such as headache, confusion, nausea, and blurred vision for weeks to months after an initial injury. Other lasting effects after bruising in the brain can include the development of learning disabilities, loss of speech or other skills, and loss of coordination. Medical imaging studies may be needed to examine the brain and locate damage.
