Memory loss can occur with mild concussions—even a single concussion can impact the ability to remember. Persistent symptoms of memory loss often happen with multiple concussions.
A concussion can cause a person to forget the events surrounding the head injury itself or the accident that caused it, parts of conversations, where things were left, retracing a route, and losing track of what day or time it is. Concussions tend to impact short-term memory more than long-term memory. Those suffering from memory issues often have trouble remembering to remember, which is referred to as prospective memory and can affect things like keeping appointments or returning phone calls. Prospective memory loss most commonly presents in individuals with moderate to severe TBIs.
Those struggling with memory problems may use memory devices such as alarms, grocery lists, written or digital reminders, pillboxes, or storing all necessary items in a specific area, and limiting or getting rid of distractions before trying to learn or remember information.
