Facts about amnesia after brain trauma


When a person in Newton suffers a head injury, there is a risk that the injury will be severe enough to cause brain trauma. There are many aftereffects of brain trauma that can have a negative impact on both the individual and the family. One such issue is amnesia. Understanding the facts about post-traumatic amnesia can help those who are affected by it or believe they might be affected by it to have a grasp on its seriousness, how to recognize it and treat it.

People who suffer from a traumatic brain injury might be confused or lose memory after the injury occurs. They might experience disorientation and have issues remembering events that happened after the injury. There is the possibility that this can extend to forgetting their name, their location, the time and other facts that were previously simple to remember, understand and state. There are two kinds of amnesia that someone might suffer from after brain trauma. They include retrograde amnesia and anterograde amnesia.

Retrograde amnesia is the loss of memories that were accrued not long before the injury occurred. This is frequently a problem when the injury is to the anterior temporal or frontal regions of the brain. With anterograde amnesia, the victim might have a problem crafting new memories post-injury. There could be both. Anterograde amnesia might not begin to show itself until hours after the injury happened. Amnesia can last for a short time or a longer time. Fewer than 3 percent have no memory loss. 6 percent have memory loss for less than one hour. Seven percent had memory loss from one hour to a day. 16 percent had memory loss for between a day and a week. Twenty-three percent suffer from amnesia for between a week and a month. Forty-five percent have it for longer than a month.

Depending on the circumstances, amnesia can cause serious problems. Brain trauma can lead to medical treatment and its accompanying expenses. They might have trouble returning to work and functioning normally making it necessary for the family to care for them or hire someone to do so. Given the nature of issues that can arise from a head injury and amnesia, it's important that those who are experiencing it discuss the cause of the traumatic brain injury and consider litigation with assistance from a legal professional familiar with personal injury cases.
