Some things are recalled and remain long in the memory, however forget other very easily. The main reason for that to happen one thing or another is often the attention or interest contained in the event.

In some cases, do not forget things, but not actually have never saved in memory. Although it is also possible that if we have been stored, but it is not possible to recover.

Process memorization

The memory is one of the most fascinating intellectual capacities of the human brain. At first the information is stored in short-term memory. This does not happen with everything you hear, see or feel. Only a few things will have enough interest to merit being remembered:

·  The resulting novel or striking and thus capture the attention.

·  Those who received first. For example in a list of names is easier to recall the first to the following.

·  Those that are associated or related to something that was already known in advance.

But most of the things that are kept initially not get to move into long-term memory. For that to happen it must happen one or more of the following assumptions:

·  The facts or information should be repeated often like the color of the car park next door.

·  The information learned relates to complementing other somehow.

·  The data, or in fact relates to sense something very significant. For example, recalls certain odors as it relates to important people.

Why is forgotten

Some things are forgotten because they are left to use for long periods of time, others are not learned the right way.

If memorizes a list of names and dates on the sole basis of rote learning, ie mechanically and without the intervention of reasoning, in a short time such information will be lost.

Sometimes the information is not forgotten, but never recorded entirely in memory in the long term. This happens because not enough arouses interest, not the eye and does not make any meaning.

In other cases the information was not forgotten, but it's hard to remember. This fact tends to be because at the time it was made storage an association wrong or different from that goal.

Loss of memory

We talk about memory loss when difficulties arise to remember previously learned skills or remember events, people or data from the past.

Memory loss is called scientifically amnesia. The causes are very different and the seriousness of it. Usually we talk about memory loss as a consequence of advancing age.

Amnesia

The amnesia involves abnormal memory loss due to an illness or disorder. This can be more or less pronounced and be permanent or temporary. According to forget what distinguishes different types of amnesia:

·  Anterograde Amnesia: the individual is unable to fix in their minds the facts which occur every day. From the time of injury and unable to remember the things that happen.

·  Retrograde Amnesia: inability to recall the events of the past that were perfectly memorized.

·  Global Amnesia: inability or difficulty in remembering both the facts of the past and the present.

Causes of amnesia

The amnesia can have different causes:

·  Diseases such as Alzheimer's or senile dementia. In these cases the loss of memory is progressive and definitive.

·  Brain Injuries caused by accidents, tumors or any other condition involving damage to the brain structures.

·  ·Illness of traumatic events. In these cases there is no physical cause amnesia. Generally just forget to do with the incident as a defense mechanism. Memory loss is temporary.

·  Because of a strong trauma or stroke. Normally recover in hours or days, depending on the severity.

·  The consumption of harmful substances can cause brain damage causing memory loss. Alcohol is responsible for such a syndrome that involves loss of memory.
