Explaining the Dejavu Phenomenon Logically

deja vu occurs when a person gets the feeling that he has experienced or done something similar to his experience in the past. The term comes from the French word meaning 'already seen'.

Although studies show that deja vu most experienced by otherwise healthy individuals, but these events can also be part of certain medical conditions, such as seizures and aura in migraines.

Various Theories in an Effort to Solve Dejavu

Many are curious about how the phenomenon deja vu could occur. Various studies have attempted to explain how a person can experience deja vu. Several explanations exist for this phenomenon, including:

• Associated with mental disorders

  Initially there was a suspicion that deja vu associated with mental disorders, such as anxiety, dissociative identity disorder (formerly known as multiple personality disorder), and schizophrenia. However, preliminary research conducted did not find strong evidence of a correlation between them.

• Relate with age and stress

  According to research, deja vu more common between the ages of 15-25 years, and generally will gradually disappear with age. Besides, the appearance of deja vu It can also be triggered by stress and fatigue. The same study also revealed that deja vu more common at night and on weekends.

• Impaired synchronization of information in the brain

  Some researchers suspect that the phenomenon of deja vu occurs because of a mismatch of information in the brain when trying to make a comprehensive perception of an event, where there is too little information, so that what appears is vague information between sensory input and output. memory-recall (recalling information from past events). However, this theory has not been able to fully explain why deja vu Another theory that is still related to the allegations above says that déj vu occurs 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 memory lane deviation, where short-term memory strays into a person's long-term memory, will cause the emergence of deja vu. This is the reason deja vu often makes us feel as if we have experienced the things we are currently experiencing in the past.

• Disorders of the medial temporal lobe

  Other studies suspect disorders of the medial temporal lobe of the brain as a trigger for deja vu. Studies conducted on epilepsy patients using electrical stimulation found that stimulation of the cortex rhinal in the brain can trigger deja vu.

Even though the cause deja vu not sure yet, but there is no need to worry if you experience it. Until now, there is no strong evidence found of serious disorders related to the health and mental health of a person who suffers from diabetes deja vu. However, if the déj vu that you are experiencing starts to bother you, you should consult a psychiatrist or neurologist for proper treatment.
