However, generally speaking, the amount of time can sometimes determine the severity of a survivor’s brain injury.įor example, some survivors may experience post-traumatic amnesia for weeks or in rare cases, months. There is no exact time frame indicating how long a survivor will experience post-traumatic amnesia. The presence and duration of anterograde amnesia is one of the best predictors of brain injury outcome. How Long Can Post-Traumatic Amnesia Last?Īnterograde amnesia is the most common type of amnesia survivors experience after a brain injury. However, it can help to remember that post-traumatic amnesia is almost always temporary and a step in the recovery process.

However, they can often remember data and events that occurred before the brain injury. This means a survivor cannot remember new information provided like a conversation they just had. Post-traumatic amnesia can be broken down into several different types: It’s important to understand this is an early stage of recovery in which the brain is healing. This can last from a few minutes to a couple weeks, depending on the severity of the brain injury. During this time the survivor may not be able to recall certain memories. Post-traumatic amnesia typically occurs after a survivor wakes up from a coma, a period of unconsciousness. Damage to one or more of these areas can often result in post-traumatic amnesia.
Several regions of the brain are involved in the process of memory including the amygdala, hippocampus, cerebellum, and prefrontal cortex.
