Encephalitis (brain inflammation) – This condition can be either viral or bacterial, and has been referred to as an acquired brain injury with effects similar to having suffered a traumatic brain injury, a stroke, or having had oxygen to the brain cut off by a cardiac arrest.Stroke – People who suffer left-brain strokes tend to lose their short-term memory capabilities, while those who suffer right-brain strokes will remember events, but confuse specific details.Though the most obvious cause of sudden memory loss is brain damage that is a result of traumatic injury, there are other functional causes, including illness, chemical reactions from drugs or alcohol, and psychological factors. There have been instances of people suffering from an acute brain infection that damaged this section of the brain losing all sense of their former identity. It is close to the midline of the brain, and that means that is rarely impacted by external structural damage.

Our personal identity is lodged in a specific part of the brain called the median temporal lobe. We’ve all seen characters who’ve been in car accidents or struck on the head, then recover consciousness and ask, “Who am I? How did I get here?” In real life there are few instances of amnesia that involve the loss of personal identity, and these are much more commonly a result of psychological distress then of illness or structural brain damage. Most of us have an image of amnesia that we get from the movies and television.

Psychogenic Amnesia – The Movie Version of Sudden Memory Loss Recent studies have indicated that the extensiveness of the memory loss is a reflection of whether damage to the brain is limited to the hippocampus or also includes the temporal cortex. The severity of the condition is often indicated by what memories are retained, as under a medical principle known as Ribot’s Law, more recent memories are lost first, with more ingrained memories tending to be less likely to be dislodged. Those who are impacted are generally able to remember meanings and other actual information, but are not able to recall specific events or situations. Retrograde amnesia occurs when a person is unable to access memories of events that happened in the past, prior to the precipitating injury or disease that caused the loss. ( Simply Psychology) Studies have also shown that patients who have been prescribed benzodiazepines, familiarly known as tranquilizers such as Valium or Xanax, can suffer from anterograde amnesia. Whatever the cause of the trauma, the person who is affected is unable to convert their short term experiences into long-term memory. This damage can be caused by an accident, as a result of surgery, alcohol, and even an acute deficiency of thiamine known as Korsakoff’s syndrome. ( Medical Daily)Īnterograde amnesia is often a permanent condition generally thought to be caused by damage to the hippocampus section of the brain. Shortly after the movie was released the news was filled with similar medical cases including a young woman whose combination of epilepsy and Functional Neurological Disorder prevent her from forming new memories, and a dental patient who had a negative reaction to anesthesia and suffered a similar loss in ability. Though the movie was fiction, it is a reflection of events that can happen in real life, and which have. Movie enthusiasts will recognize this form of amnesia from the popular film Fifty First Dates. When a person is unable to store and retain new information but is able to recall data and events that happened previously, it’s known as anterograde amnesia. They do not lose their implicit or procedural memory, which is what allows us to perform functions such as operating a cell phone or riding a bike. When people suffer from sudden memory loss, the memories that they lose are generally what are known as episodic or explicit – they forget events and facts. Where retrograde amnesia is a failure in the brain’s ability to retrieve information, anterograde amnesia is a failure in the ability to store information.

It can be either retrograde, in which the person forget what happened before their memory loss, or anterograde in which they are no longer able to remember things that happen to them after. Sudden memory loss is more commonly referred to as amnesia.

Read the full article below for the explanation. The major difference between retrograde amnesia and anterograde amnesia is the following: Retrograde amnesia is the inability to recall past memories while anterograde amnesia is the inability to create new memories.
