Explain Dejavu Phenomena Logically

Various Theories in Dejavu Solving Efforts

Many are curious about how the phenomenon of dejavu can happen. Various studies have tried to explain how one can experience dejavu . Some explanations are available about this phenomenon, including:

  • Related to mental disorders
    Initially there was a suspicion that dejavu was related to interference mental, such as anxiety, dissociative identity disorder (previously known as compound personality disorder), and schizophrenia. However, the initial studies conducted did not find strong evidence regarding the correlation between them.
  • Relate to age and stress - According to research, dejavu is more common in ages between 15-25 years, and generally will gradually disappear with age. In addition, the appearance of dejavu can also be triggered by stress and fatigue. The same research also revealed that dejavu is more common during evenings and weekends.
  • Disruption of information synchronization in the brain
    Some researchers suspect that the phenomenon of dejavu occurs because of an incompatibility of information in the brain when it wants to make a thorough perception of an event, where there is too little information, so that what appears is vague information between sensory input and memory-recall output (recall information from past events). Even so, this theory has not been able to fully explain why dejavu can happen.

    Another theory that is still related to the above assumption says that dejavu arises due to brain failure in a very short period of time, resulting in a collision between long-term and short-term memory. In this theory it is said, the existence of a memory pathway, where short-term memory gets lost into a person's long-term memory, will cause dejavu . This is the reason dejavu often makes us feel as if they have felt things that have been experienced in the past.

  • Disorders in medial temporal lobe
    Other studies suspect interference with the medial temporal lobe of the brain as a trigger for the occurrence of dejavu. Studies conducted in epileptic patients using electrical stimulation find stimulation in the cortical area rhinal in the brain can trigger dejavu.

Although the cause of dejavu cannot be ascertained yet, but there is no need to worry if you experience it. Until now there is no strong evidence of a serious disorder related to the health and mental health of a person who has experienced dejavu. However, if the dejavu you experience starts to feel annoying, you should consult a psychiatrist or neurologist for proper treatment .
