A concussion is a kind of brain injury that can have temporary or permanent effects, depending on severity. Headache is the most common symptom, however, if brain functions are affected, other symptoms can include problems with memory, concentration, coordination, and balance.
A concussion is often caused by trauma such as a blow, bump, or jolt to the body. These sudden movements can cause the brain to rock rapidly back and forth in the skull, which can stretch and damage brain cells, and even cause the brain to react chemically in a negative way.
Injuries brought about by mild concussion typically won’t show up in an MRI, making these imaging techniques at times unnecessary. However, an MRI is recommended for concussion cases that involve the following:
- Loss of consciousness that lasts more than a minute
- Worsening or persistent symptoms
- Severe headache
- When intracranial structural injury is suspected
- Impaired speech
- Diminishing quality of vision such as double vision, tunnel vision, and even total vision loss
- Difficulty staying awake
- Inability to focus on surroundings
- The sudden onset of throat issues such as difficulty swallowing, frequent choking, and reduced gag reflex
An MRI is the preferred diagnostic imaging tool of choice for a concussion injury if imaging is needed 48 hours or longer after the occurrence of the injury. An MRI scan is useful for evaluating worsening or persistent symptoms, or when pre-existing conditions are a concern. The technology’s superior ability to detect traumatic lesions in the brain, along with its non-use of damaging radiation, is why it is highly recommended for evaluating sports brain injuries, most especially when the acute period has elapsed.
