Almost all of us, at least once, got this feeling: ‘I’ve experienced this before.’ Or, ‘I might have seen this place before.’
This feeling, called ‘Deja vu’, is a situation in which some people are often alive and familiar. Why is deja vu nedir, why and in whom?
According to the researches conducted, about 2 out of 3 people experience this feeling at least once during their lifetime. Can ‘deja vu’, which is mostly seen in people aged 15-25, be a symptom of illness or disease?
What is Deja vu?
Déjà vu (deja vü), composed of the words déjà (before) and voir (deja vu) in French, is a feeling of having already seen a place or place that has lived or seen before. Those who feel that you have already experienced the event you are already living in, often can not remember the detail and reason.
It should be pointed out that if deja vu is not experienced very often, deja vu is definitely not a sign of disease or illness. Deja vu is a small anomaly in the brain’s workings and does not necessarily mean that you have a physical or mental problem to emerge. But if this feeling is repeated all the time, then only then can you suspect the disease.
Who is Deja vu seen?
Before; people with schizophrenia, anxiety disorder and depression were thought to be relatively common. However, the investigations showed that these disorders did not involve any interest in deja vu.
Deja vu, more commonly seen in ‘epilepsy’ patients. Before the seizure, deja vu, which arises when consciousness is open, can cause someone to have more severe attacks. For this reason, especially in childhood and adolescence when deja vu is very common, a doctor should be consulted and it should be understood whether or not it is an epileptic disease. Deja vu, in adults, stress, fatigue, etc. can be caused by causes.
What causes Deja vu?
The term ‘deja vu’, first used by the French physicist Emile Boirac in 1876; and in 1928, in the scientific literature, Edward Titchener’s book ‘A Book of Psychology’. Dr. According to Titchener, the brain generates a partial perception before producing a precise perception of the experiment, which causes the deja vu sensation to be experienced.
In the scientific explanation of Deja Vu: The operation of the right lobe of the brain and the left lobe with a smaller time difference than the millisecond … Since one side perceives the other side earlier, the late perceiving side seems to have experienced this event earlier. In other words; This event is caused by a small deviation in the nerve axons.
According to the findings obtained from the researches done, deja vu can be experienced just before the temporal lobe crisis arrives. The closeness strengthens the fact that electrical currents that cause anomalies at the neurological level lead to deja vu. It is also suggested that deja vu may be useful in early diagnosis of Alzheimer’s disease. However, this theory is not right now.
