causes

     there are many causes of amnesia some are as following,

 

• electric shock.
• an injury to brain.
• tumor in the brain.
• intoxication or drug abuse.
• during surgery waste of brain cells.
• severe shock to brain.

 

The most common types of amnesia are:

 

Anterograde amnesia:

 A person with anterograde amnesia cannot remember new information. This usually results from brain trauma, such as a blow to the head that causes brain damage. The person will have their full memory from the time before the injury.

Retrograde amnesia:

In some ways the opposite of anterograde amnesia, retrograde amnesia is when a person cannot remember events that occurred before their trauma, but they can remember what happened after it. In rare cases, both retrograde and anterograde amnesia can occur together.

Transient global amnesia:

This is a temporary loss of all memory and, in severe cases, difficulty forming new memories. This is very rare and more likely in older adults with vascular (blood vessel) disease.

Traumatic amnesia: 

 This refers to memory loss resulting from a hard blow to the head, for instance, in a car accident. The person may experience a brief loss of consciousness or coma. This type of amnesia is usually temporary, but its duration often depends on the severity of the injury. Amnesia can be an important indicator of concussion.

Fugue or dissociative amnesia:

 Rarely, a person can forget both their past and their identity. They may wake up and suddenly have no sense of who they are. The trigger is usually a traumatic event. The ability to remember commonly returns within minutes, hours, or days, but the memory of the triggering event may never come back completely.

Posthypnotic amnesia:

A person cannot recall what occurred while they experienced hypnosis.

Source amnesia: A person can remember certain information but not how or where they got it.

Alcohol-induced amnesia:

 Also called a blackout, this is when a bout of heavy drinking leaves a person with memory gaps.

Prosopamnesia:

The person cannot remember faces. People can either acquire Trusted Source it or be born with it.

Treatment

In many cases, amnesia resolves without treatment. However, if an underlying physical or mental disorder is present, treatment for that condition may be necessary.

 

Psychotherapy or cognitive behavioral therapy (CBT) may help some people with amnesia. Hypnosis can be an effective way of recalling forgotten memories. Working on retrieving memories and managing psychological issues that may have contributed to amnesia are important aspects of any amnesia treatment.

 

Meditation and related mindfulness activities may help a person relax the mind, which may help retrieve forgotten memories.

 

Family support is also crucial. Showing the person photographs of past events, exposing them to familiar smells, and playing familiar music may help.

 

There are currently no drugs available for restoring memory lost due to amnesia. However, there are treatments for the underlying causes.

 For example, Wernicke-Korsakoff syndrome (WKS) can involve memory loss due to a thiamin (vitamin B1) deficiency, so targeted nutrition that supports any nutritional deficits can help. Whole grain cereals, legumes (beans and lentils), nuts, lean pork, and yeast are rich sources of thiamin. Those with WKS also need to stop drinking alcohol.

 

People with amnesia due to head trauma may need surgery to remove blood buildup in the brain. People with encephalitis may need anti-inflammatory medications.
