Which of the following is NOT an indicator of mTBI?

Severe memory loss is not typically considered an indicator of mild traumatic brain injury (mTBI). While mTBI can lead to some memory issues, they are usually less severe and temporary, often referred to as transient memory loss or difficulty with memory recall immediately after the injury. Severe memory loss suggests a more significant injury or concussion, possibly indicating complications such as post-traumatic amnesia or other brain injuries, which go beyond the scope of mTBI.

In contrast, ear ringing (tinnitus), double vision (diplopia), and headaches or vomiting are commonly recognized symptoms associated with mTBI. These symptoms can occur as a result of the brain's response to trauma, leading to disturbances in sensory processing and physical stability. Thus, while mild memory issues may arise, they are generally not categorized as "severe," which aligns with the characteristics of mTBI.
