There are three known types of memory: 1. Short-term memory(STM, also known as working memory) – these are thoughts that are temporary, usually lasting between 10-30 seconds. The frontal and parietal lobes of the brain are mostly responsible for STM. 2. Long-term memory(LTM) – thoughts that last beyond a minute or longer become an LTM. This is usua...
There are two main features of amnesia. Someone may have difficulty learning new information following the onset of amnesia, or they may have difficulty remembering past events and information previously familiar to them. The symptoms of amnesia depend on the type of amnesia being experienced. Some of the common experiences of someone with amnesia ...
Anterograde amnesia
If someone has anterograde amnesia, they cannot remember new information. The person can remember information and events that have happened before the onset of amnesia, but things that happened more recently and information that should be stored in STM disappear. The effect of this type of amnesia can be temporary, such as when experiencing a blackout from consuming too much alcohol. It can also be permanent if the hippocampus becomes damaged, an area of the brain that plays a significant rol...
Retrograde amnesia
In contrast to anterograde amnesia, someone with retrograde amnesia will be unable to remember old memories. In this instance, they cannot remember the events that occurred before the onset of their amnesia, but they can remember what happened afterward. They will essentially lose their existing, previously made memories. This type of amnesia tends to affect the most recently formed memories first, so the events immediately leading up to the onset of amnesia will likely be forgotten first. In...
Transient global amnesia
Transient global amnesia is when someone has a temporary loss of all memory and, in severe cases, difficulty forming new memories. This type of amnesia is very rare and is likely to occur in older adults with vascular disease. It is a sudden and temporary memory loss lasting between one to ten hours. When experiencing transient global amnesia, a person cannot make new memories or recall events during the period of amnesia. They can remember deeply ingrained information such as who they are an...
Neurological
Neurological amnesia is caused by various brain diseases, injuries, infections, or other medical conditions. Other causes of this type of amnesia include: 1. Stroke 2. Brain inflammation 3. Lack of oxygen to the brain, e.g., from a heart attack or respiratory distress 4. Long-term alcohol abuse 5. A vascular disease that has been known to cause transient global amnesia 6. Tumors in the areas of the brain that control memory 7. Degenerative diseases such as Alzheimer’s disease 8. Seizure activ...
Functional
Functional causes of amnesia are usually related to psychiatric or emotional trauma. Functional amnesia also usually only causes retrograde amnesia and doesn’t affect the ability to form new memories, although in severe cases, people with functional trauma can forget who they are. Dissociative amnesia stems from emotional shock or trauma, such as experiencing or being the victim of a violent crime or experiencing or being the victim of emotional, physical, or sexual abuse. With this type of a...
To diagnose amnesia, doctors usually complete a comprehensive evaluation to rule out other possible reasons for memory loss. The doctor will want to rule out conditions such as Alzheimer’s, other forms of dementia, depression, or a brain tumor. The evaluation may begin by completing a thorough medical history of the individual. As the person with s...
With many types of amnesia, no treatment is necessary as it is likely that memory will return to normal in a short amount of time. For instance, amnesia from mild head trauma may resolve within minutes or hours. Amnesia from a severe head injury may last a bit longer, for up to a week. In rarer cases, amnesia from a severe head injury may last for ...
In many cases, amnesia is not preventable. However, there are some ways to keep the mind active and the brain protected, especially when getting older, which could prevent age-related memory loss:

Jason Bourne has amnesia which refers to lacking memory. Now, memory can be divided into two main types. The first is implicit memory, also known as procedural memory. Procedural memory refers to replicating the sorts of skills you can perform automatically, without thinking much about it.

Amnesia is an active process in which memory consolidation or reconsolidation is impaired, leading to a loss of long-term memory formation. It is characterized by a time-dependent reorganization of processes and can be classified as specific anterograde amnesia. AI generated definition based on: Neuroscience & Biobehavioral Reviews, 2020.
