What is the term used to describe the loss of memory for events immediately before a brain injury?

The term that describes the loss of memory for events immediately before a brain injury is retrograde amnesia. This type of amnesia specifically affects memories formed prior to the onset of amnesia, which can be due to trauma, injury, or various other factors. When someone experiences retrograde amnesia, they often struggle to recall information or events that occurred just before the incident that caused the amnesia, while their ability to form new memories may remain intact.

In contrast, amnesia is a broader term that encompasses various memory loss types but does not specify the timing of the memory loss. Anterograde amnesia, on the other hand, refers specifically to the inability to form new memories after the onset of amnesia. Short-term memory loss typically pertains to difficulties with information retention over brief periods and does not specifically relate to events prior to a brain injury.
