Understand Amnesia in Simple Words
Amnesia or Amnestic Syndrome refers to the large scale loss of memories, such as vital facts, information, key people in our lives and memorable events and but usually they know who they are. But, they may have trouble learning new information and forming new memories. Amnesia can be caused by damage to areas of the brain that are vital for memory processing and though a person can no longer memorize or recall information that is stored in memory. In some cases of Amnesia, it is difficult to recover lost memories, and thus patients are kept under the supervised conditions.
Amnesia differs in severity and scope from patient to patient, but even mild amnesia leaves its impact on daily activities and can cause problems at work, school and in social settings.
Major Types of Amnesia
There are multiple types of amnesia but we are briefly describing the major ones here:
1. Anterograde Amnesia
When a patient is suffering from anterograde amnesia, he has difficulty in forming new memories but the effect can be temporary. Such as a person can undergo anterograde amnesia during a blackout caused by consuming too much alcohol. It can also be permanent. You can experience it if the area of your brain which is known as your ‘hippocampus’ is damaged as it plays a crucial role in creating new memories.
2. Retrograde Amnesia
It is totally opposite of anterograde amnesia, in this amnesia patient loses existing and previously made memories. In simple terms, a person cannot remember incidents that happened before his trauma or accident, but he will remember what happened after it. This type of amnesia tends to affect recently formed memories first. Older memories, such as memories from childhood, are usually affected more slowly. Disorders such as dementia cause gradual retrograde amnesia.
3. Transient Global Amnesia
In the case of transient global amnesia, the patient will experience confusion, anxiety or irritation that comes and goes frequently over some hours. A patient may also experience memory loss in the hours before the trauma or accident, and he will probably have no lasting memory of the trauma. Many health reports also stated that it occurs due to abduction or seizure-like activities or a slight blockage of the blood vessels supplying your brain. It occurs more often in adults or middle-aged people.
4. Childhood Amnesia
Most people don’t remember their first three to five years of life. This common phenomenon is termed as infantile or childhood amnesia. The person cannot recall events from early childhood, probably because of a language development problem or some memory areas of the brain not fully developed during childhood.
5. Traumatic Amnesia
In this case, loss of memory happens due to a hard blow or sudden shock to the head, for example, a car accident or terrorist attack, or natural phenomena such as flood or earthquake. The person may experience an immediate loss of consciousness or a coma. The amnesia is usually temporary, but how long it lasts it is hard to say, normally depends on how severe the injury is.
