High blood alcohol concentration can also lead to short-term anterograde amnesia, and in some cases, this form of amnesia can be drug-induced under proper medical care. One can suffer from a head trauma and see the effects of amnesia, or they may have experience a traumatic or emotional instance that causes extreme stress or shock. People with this type of amnesia suffer an organic disruption to the memory process and cannot explicitly remember experiences after the event that caused their memory disruption. There are a few different causes of anterograde amnesia. The article gives the definition of anterograde amnesia as, a form of amnesia where new memories are not encoded into long-term memory. Depending on the incident that caused the amnesia episode, there may be a way to improve one’s memory but not always a way to reverse or cure one’s memory. They may remember specific moments from a year ago, but would forget something that happened the day before.Īnterograde amnesia is a very complex form of amnesia that can be either temporary or permanent. Following the ingestion of a benzodiazepine, short-term memory is not affected, but long-term memory is impaired. From that point on, a person can have the inability to store information in their short-term memory.

This affects one’s long-term memory. Anterograde amnesia, however, is the loss of short-term memory, and happens AFTER a certain event happens. This could mean that after a car accident, someone forgets their past. Retrograde amnesia is the loss of memory before a specific point or event in one’s life. If so, you know that when someone has amnesia, they suffer from a form of memory loss, either from an emotional, stressful situation (stemming from post-traumatic stress disorder) or from an injury or trauma to the head or brain.Īmnesia can be broken into two parts–anterograde and retrograde. You may be familiar with amnesic episodes. Although people hear the term amnesia quite often, there is often a misunderstanding of a few key facts.
