What is Amnesia? Amnesia Symptoms and Treatment

Amnesia refers to the difficulty an individual has in accessing the information stored in their brain. Amnesia, a rare condition, is a popular subject of many movies and books. Everyone can experience a moment of forgetfulness from time to time. However, forgetfulness is a completely different condition from amnesia. In amnesia, there is a great loss of information that should not be forgotten. Important moments in life, important events, people we encounter in key roles in our lives, and important information about life are among the issues of memory problems that may occur with amnesia. You can find the answers to what amnesia means and many other questions on this subject in the rest of the article.

What is Amnesia?

Amnesia refers to loss of memory regarding facts, various information and experiences. Individuals with amnesia in movies and books often have problems with their personalities, but this is not the case with amnesia in real life. Amnesia may occur due to damage to various structures in the brain that are involved in memory processing. One must be aware as amnesias other than temporary memory loss (transient global amnesia) may be permanent.

In addition to difficulty remembering the past, individuals suffering from memory loss may also experience problems with cognitive functions such as processing new information in the brain or making plans for the future. This may also indicate that future plans are shaped by past experiences and experiences we have gained.

There is currently no specific treatment for amnesia. However, learning memory-enhancing techniques and receiving psychological support can make it easier for both individuals and families to cope with amnesia.

What are the Types of Amnesia?

Amnesia types are divided into many subtypes. What these types of amnesia are and their characteristics can be summarized as follows:

• Retrograde Amnesia

Individuals experiencing retrograde amnesia have difficulty remembering previously created memories. This type of amnesia generally tends to affect recently formed memories. Older memories are generally unaffected. Dementia and dementia-related disorders can gradually cause retrograde amnesia to develop.

• Anterograde Amnesia

People suffering from this type of amnesia have lost the ability to form new memories. This memory loss may be temporary after excessive alcohol consumption, or it may occur permanently after damage to the hippocampus, the area of ​​the brain responsible for memory. People who experience anterograde amnesia due to trauma can remember information and events from before the event.

• Transient Global Amnesia

Transient global amnesia is a type of memory loss that is not yet fully understood. In individuals who develop this type of amnesia, memory loss occurs in the form of recurrent episodes of confusion and agitation, but transient attacks that last for several hours. Individuals with transient global amnesia who develop memory loss about the period before the attack do not have any memories of the attack.

Scientists believe that this type of short-term memory loss occurs due to seizure-like brain activity or short-term blockage in the blood vessels responsible for feeding the brain. Transient global amnesia occurs especially in middle-aged and older individuals.

• Infantile Amnesia

Individuals experiencing infantile amnesia have difficulty recalling memories from early childhood. The underlying reason for this situation may be problems that occur during language development in childhood.

• Traumatic Amnesia

Traumatic amnesia, which can occur as a result of heavy blows to the head, occurs especially in individuals who have experienced severe trauma such as traffic accidents. In addition to sudden memory loss, these people may also experience short-term loss of consciousness or coma. Although traumatic amnesias are generally temporary, how long memory loss lasts may vary depending on the severity of the trauma experienced.

• Wernicke-Korsakoff Psychosis

Wernicke-Korsakoff syndrome, which occurs with long-term excessive alcohol use, is a cause of memory loss that tends to worsen over time. This health problem, which is accompanied by neurological symptoms such as loss of coordination or tingling and numbness in the fingers, in addition to memory loss, occurs due to vitamin B1 deficiency, which occurs due to the use of high doses of alcohol for a long time.

What are the causes of amnesia?

Any history of brain-related disease or trauma may affect memory-related functions. Memory and recall-related functions are functions that are in contact with many parts of the brain. Amnesia may develop in cases of damage to brain structures that affect the limbic system, especially the hippocampus and thalamus. Medical reasons other than trauma that may result in amnesia can be summarized as follows:

• Stroke
• Inflammation in the brain tissue, referred to as encephalitis
• Lack of oxygen due to heart attack, respiratory problems or carbon monoxide poisoning
• After the use of various drugs
• Bleeding in the membranes between the skull and brain
• Presence of a brain tumor that interferes with memory-related functions
• Some diseases with seizures
• Electroconvulsive therapy applications

Apart from medical causes of amnesia, amnesia may also develop as a result of various psychological events. This memory loss, which usually results from a state of emotional shock, may occur as a result of witnessing a serious crime, being abused, participating in military combat, natural disaster or acts of terrorism. This condition, referred to as dissociative amnesia, causes amnesia to develop at different levels depending on the degree of stress of the event.

What are the symptoms of amnesia?

There are two basic symptoms that may occur in people with the development of amnesia:

• Having problems processing new information
• Difficulty remembering past events

Individuals experiencing amnesia often have problems with short-term memory. In addition to the loss of recently processed information, some people may also have difficulty recalling past memories and experiences.

There are many other signs and symptoms that may accompany amnesia:

• Recalling unreal memories, called conphobia, or having different concepts of time or space in memories than real ones.
• Difficulty making coordinated movements or tremors
• Confusion
• Difficulty recognizing faces and places

It should be noted that amnesia is a memory loss that works differently than dementia. In addition to the memory loss that occurs in dementia, there are many other neurological symptoms that make the person’s daily life very challenging.

How is Amnesia Treated?

Many cases of amnesia can resolve spontaneously without any treatment. However, it is important for individuals to receive medical treatment in the presence of underlying physical or mental problems. The treatment method applied varies depending on the type of these underlying conditions. Psychotherapy practices contribute to solving memory problems in some individuals.

Detoxification of alcohol and other substances may be beneficial in the type of amnesia triggered by chemical substances. A significant improvement in memory problems can occur with the removal of medication or alcohol from the body.

Amnesia caused by a moderate head injury is a condition that can disappear over time. However, if the trauma is quite severe, people may also develop permanent amnesia. With early diagnosis and appropriate intervention, amnesia due to head trauma usually regresses within 6-9 months.

Various therapy applications may be beneficial for individuals who constantly complain of memory loss. During these sessions, people can gain useful habits on how to process new information or continue their daily lives.
