For how long does memory loss last in a mild TBI?

In cases of mild traumatic brain injury (TBI), memory loss specifically related to the incident typically lasts less than 24 hours. This is characterized as post-traumatic amnesia, which is a common symptom following a concussion or mild TBI. Individuals often display a brief period of confusion or disorientation immediately after the injury but recover relatively quickly within this timeframe.

The recognition of this short duration of memory loss is critical for understanding the severity of the injury and managing the patient's care appropriately. This duration of less than 24 hours distinguishes mild TBI from more severe forms, where memory loss and cognitive impairment can persist much longer and often requires more intensive medical interventions. Hence, options suggesting a longer duration of memory loss are not consistent with the characteristics of mild TBI.
