Is “brain short circuit” a normal phenomenon or a symptom of disease

  Have you ever experienced the following awkward “brain short circuit” scene?
  When talking with others, an idea suddenly came to mind, and when you just finished the last sentence, or listened to the last sentence of the other person, and wanted to use voice to present the thought in your mind, this idea– Suddenly-disappeared? Scientists call these “tip-of-tongue phenomena”, which vividly describe the embarrassment of not being able to speak up to the tip of the tongue. Ordinary people jokingly call it “brain short circuit”.
  The current popular explanation is that you suddenly forget your thoughts at the last moment, or suddenly fail to remember familiar things, which is mainly caused by a decline in working memory. The reason is that the amount of information currently processed by our brain is huge, and it has been overloaded!
  Occasionally the “tip of the tongue” phenomenon is completely normal, and it is unlikely to affect our communication with others. Generally speaking, the essence of this phenomenon is temporary forgetting in the process of recalling. It is only a special phenomenon of memory and has nothing to do with memory decline. But when the “tip of tongue phenomenon” gradually increases, reaching several times a day, we need to pay attention to it. Physiological transient forgetting increases, which can be seen in situations such as taking drugs and drinking alcohol.
  Too many similar phenomena may also be signs of some diseases, such as mild cognitive impairment in the elderly, Alzheimer’s disease, and organic brain diseases.
  Therefore, when the “tip of the tongue” appears frequently, suddenly and progressively increases, you need to go to the psychiatric department or neurology department in time.
