Why I Do Not Remember My Childhood?
Almost all of us, when think about our past especially childhood, we do not remember clearly what we did, thought or felt in our childhood.
It is common among all of us that we have a thing like memory void which lasts during the first years of life. It may be that a person feels that he remembers something but in reality, that memory is influenced by a photograph or a comment from a person.
Nobody has memories from the birth to 5 years of age. This is the conclusion researchers have made in a study to answer the question. In this article, we will describe why we do not remember our childhood, and to know more how the researchers made that conclusion, read the article till the end.
Why We Do Not Remember Our Past Or Our Childhood?
A study was conducted by the researchers Paul Frankland and Sheena Josselyn about the memory during the first years of life. Their main focus was on trying to find out why a person does not remember the episodes of his childhood. Emotions, moments or experiences of our early years are not usually remembered by our memory.
They have found that the main reason for this situation is biological causes. At the early stage of life, the production of neurons is very high in the child. A newborn child’s brain is only 25% developed.
During the first three years of life, the growth of the brain is very advanced since, in this period, an organ that is twice as large is achieved.
Until five years of the age, its growth continues to be very fast and after that, the speed begins to decrease. In the adolescence, the growth of a human brain is stopped and it is the time when it begins to mature.
Neurogenesis is the term used to define all this procedure of cerebral and neuronal formation. It also allows us to remember and learn more as we grow.
Note: Another unexpected effect of neurogenesis was found by the researchers who carried out this experiment. They found, neurogenesis also produces an effect of erasing the memories.
The Study Of Childhood Memories
A study that was published by Paul Frankland and Sheena Josselyn answered why we do not remember the memory of childhood. Both doctors observed the behavior of the brain of young mice and compared them with that of an older mice.
They observed that hippocampus which is the area of the brain responsible for learning and memories, neural generation was different in both brains.
From this research, they concluded that in the first five years of age a massive production of new neurons occurs in the hippocampus. This is because the activity of the brain during these years of life is very high in the hippocampus. That is why this dynamism prevents the memory from being stored in a proper way.
Note: After first five years of life, the neuronal activity stabilizes and remains more stable. Therefore, from then on we can start to store memories.
Causes Why We Do Not Remember Things?
In our daily routine, it is usual that we suffer some memory loss. Our memory is working day to night, all the time, and it is obvious that it will fail us at some point.
It is not because we are having memory loss issue, actually, it is due to the fact that we are saving so much memory with each passing moment and so many thoughts are running in our mind that we sometimes feel difficult to memorize. To store new data our brain automatically erases some of the past memories.
We can notice that when we change our daily routine or any habit our brain finds it harder to adapt to new memories. There can be many reasons for this daily forgetfulness and some of them are given below:
Having Stress And Anxiety
Any kind of change in the state of the nerves can lead us to suffer memory loss. When our body is under stress or anxiety there will be thousands of things in our mind at the same time, to take care of. So much pressure on the brain can result in the loss of some memory.
It is natural and usual that when we are in depressive state our brain does not perform its functions correctly. Due to this state of mind, some functions of the brain are affected such as storing the memory.
Women with menopause may feel that their brain functions are affected. The reason is the hormonal change that is experienced at this stage can eventually affect the natural state of organs such as the brain.
Traumatic Brain Injuries
Being suffered by a trauma in this area of the body can lead to some complication with the storage of memories. In these cases, it is recommended that you go to a neurologist for a detailed examination. Sometimes a more serious injury can cause the complete loss of memory.
Alcohol And Drug Abuse
The abuse of alcohol and drug extremely affect the state of our brain. It can damage some of the vital functions of the brain such as memory. Surprisingly, a French study in 2018 has revealed that the abuse of alcohol is the important risk factor for dementia.
Note: Dementia is the leading cause of early deaths and it can shorten the lives up to 20 years.
Some conditions such as hypertension, kidney problems, the presence of cholesterol in the blood or damage to the thyroid can also damage the health of our brain.
