Dissociation is a term used to describe a variety of phenomena that occur when one part of consciousness (the conscious mind) leaves the body and interacts with other parts of the brain, such as the unconscious or subconscious. These interactions are called “dissociated” because they involve a separation from the usual patterns of thinking and feeling that normally go on within the person’s normal awareness.
The word “amnesia” comes from the Greek words amenos meaning “without memory” and ameros meaning “free.” This means that there is no recollection of what happened before the event which caused the loss of memory. The person is still able to learn new information.
Dissociation is a separation from reality which can be mild or severe. If a person feels a sense of no fear, no pain and not being in danger when an event occurs which would otherwise be traumatic this is called a “dissociative state”. Dissociation is a defense mechanism that the brain uses to protect itself from intense or prolonged emotional trauma.
Dissociation and amnesia are two separate things. Amnesia is the inability to recall memories while dissociation is a separation of memory, identity, consciousness or awareness. Dissociation can be defined as a loss of connection to reality, while amnesia is the inability to remember.
It is a normal part of life to sometimes forget experiences that are less important. But in dissociative amnesia, you forget experiences that are very important or significant in your life. Some people experience dissociative amnesia only once in their lives while others have it more often.
Dissociative amnesia is rare and affects both children and adults. The person experiencing the disorder will have sudden and unexpected gaps in their memory with no apparent reason. In some cases, the person might not remember the event that occurred only a few minutes ago.
If left untreated the disorder can become permanent.
Types of dissociative amnesia
There are three main types of dissociative amnesia: localized, selective and generalized.
This is the most common form of dissociative amnesia. The patient has a gap in his memories for a particular period of time that is localized to a particular place. Usually the person can remember things that happened before or after the period of localized amnesia.
For example, the person may not remember what happened on a particular trip to Mexico, but he might remember other things such as his childhood or other events that occurred after he returned from the trip to Mexico.
Also called “closed-head injury” or “retrograde amnesia.” The patient has a gap in his memory for a particular period of time but the loss is confined to a specific area usually related to the injury. The patient may have periods of memory loss for longer or shorter periods of time that are confined to a specific area.
The patient has lost most or all memories of his life. He may not remember his family members or friends. The memory loss is not confined to a specific period of time or area.
This is the rarest form of dissociative amnesia.
The following are the main diagnostic criteria for dissociative amnesia:
Problems with episodic memory (not just memory in general) that are severe enough to interfere with daily life and that aren’t accounted for by alcohol or drug use, other general medical conditions or neurological problems.
The person is over the age of 18 and under 65 years of age.
The problems with the person’s memory are not due to the direct effects of drugs, alcohol or other medications and the problems cannot be due to the direct effects of a general medical condition.
Diagnosis criteria for dissociative amnesia (Dissociative fugue and depersonalization/derealization disorder are also included)
The patient displays impairment in the person’s memory that is sudden in onset and unexplained.
The problems with the person’s memory are not confined to a specific area in which the patient has lost knowledge such as memory problems related to a specific accident or injury.
The person’s memory loss cannot be explained by the direct effects of alcohol, drugs or other medications not taken in toxic amounts or other general medical conditions.
The person’s memory loss is not due to normal forgetfulness that happens as a natural part of aging.
The person with a suddenly acquired and unexplained loss of memory has one or more of the following symptoms:
1. Inability to learn new information (anterograde amnesia).
2. The inability to recall stored memories from the past (retrograde amnesia).
3. A sense of confusion or disorientation about who one is (derealization).
4. A sense of detachment from one’s personal identity (depersonalization).
5. A sense of having a hold on one’s self (i.
e. feeling that one is somehow not real).
6. Loss of personal memories (i.
e. memories about one’s past) in addition to an inability to learn new information (anterograde amnesia).
In some cases, the person may have a combination of retrograde amnesia and anterograde amnesia. In other words, the person may not only be unable to recall information from their past and unable to learn new information, but also unable to retain that information for any length of time.
The person may also experience periods of memory loss that are confined to a specific area. This can include the loss of certain skills, knowledge or even identity.
For example, a patient may have trouble remembering the events of their life or where they live (generalized amnesia) and at the same time forget how to drive, take care of their children or perform other common everyday tasks.
Alternatively, a patient may have severely impaired memory of the events of their life but retain some knowledge and ability to perform certain skills or functions (specialized amnesia).
For example, they may have no memory of their family or childhood but know how to take public transportation and manage their finances.
In rare cases, a person may display symptoms of both generalized and specialized amnesia. In other words, their memory problems encompass not only their past but their present as well.
The symptoms of amnesia do not occur exclusively during the course of another mental health disorder or due to the direct effects of a drug or other medical condition.
The person’s amnesia is not a normal part of a cultural or religious practice.
The person’s amnesia cannot be explained by the normal effects of aging.
The person’s amnesia doesn’t occur exclusively during the course of a delirious disorder.
The amnesia symptoms are not due to normal memory loss that goes along with a major depressive disorder or other mental health condition.
The person with amnesia does not have a psychotic disorder such as schizophrenia.
The person with amnesia does not have a learning disability or some other condition that might affect memory.
The person with amnesia is not suffering from some other condition that might cause the loss of memory.
In cases of amnesia, it is important to rule out a number of causes. The most common cause is alcoholism or other drug abuse.
Other causes of memory problems include vitamin deficiencies, traumatic brain injury, side effects of medical treatment, side effects of prescription drugs, side effects of recreational drugs or abuse of drugs and alcohol.
A person’s memory can also be affected by a number of mental health disorders. These include, but are not limited to, depression, anxiety, post-traumatic stress disorder, obsessive compulsive disorder and bipolar disorder.
Aura: A sensation that occurs just before a migraine headache, such as the flashing of lights, zigzag lines, blurred vision or twirling geometrical shapes.
Automatic behavior: The ability to perform certain tasks over and over without thinking about what you are doing, like driving to work or riding a bike.
Automatic behavior is different from daydreaming because you don’t have conscious control over what you are doing.
Automatic behavior can be a result of lack of concentration and attention.
Binge eating: The rapid consumption of an excessive amount of food within a short period of time.
Binge eating differs from simple overeating in that with binge eating the person feels a loss of control over their behavior.
Binge eating can occur as a result of emotional problems or stress.
Binge eating can lead to obesity and other health problems.
Black out: A loss of memory for events that occurred while a person was drinking alcohol.
Blacking out is different from passing out because the person remains conscious and can walk and talk.
Black outs are usually short, typically lasting for a few minutes or less.
Black outs occur when a person drinks enough to raise their blood alcohol concentration (BAC) to 0.15% or higher.
Black outs can be dangerous because the person can perform complex actions yet have no memory of doing so later.
Bogginess: A non-technical term used to describe the haziness of vision that occurs in some people when they wake up.
Bogginess is also called sleep vision or morning haze.
Bogginess typically disappears within a few minutes after waking up.

Cognitive reserve: The brain’s resilience when faced with a neurological insult such as a stroke.
Research on cognitive reserve has linked it to education level and complex mental activity such as reading, writing, and engaging in mentally challenging job duties.
Higher levels of cognitive reserve can limit the impact of neurological insults.
Cognitive therapy: A type of psychotherapy that aims to help people with anxiety disorders, including panic attacks.
Cognitive therapy involves swapping irrational thoughts that lead to anxiety with more rational thoughts.
Cognitive therapy can be effective in helping people with panic disorder.
Concorde Fallacy: A common logical fallacy in which people conclude that a program being costly and inefficient means its cost effectiveness must get worse the longer it runs.
The fallacious assumption is that the longer a program runs, the more money is spent on it, when in reality costs generally stay the same and only additional benefits are accrued as time goes on.
A good example is flu vaccines. The initial cost of developing a vaccine may be high, but the cost of each additional vaccine is very low.
Confirmation bias: A type of cognitive bias in which a person looks for and focuses on information that confirms their beliefs while ignoring information that does not.
People with this bias often react to disconfirming information as a threat and engage in various avoidance tactics.
People who have this bias can have very long term stable beliefs that are not justified by an objective evaluation of the evidence.
