Imagine waking up every morning and feeling like you’re living the same day every day, just like the day before, like deja vu. It sounds like a plot from a movie, but it is a symptom of an extremely rare disease called déjà vico.
What is déjà vu?
A complication of Alzheimer’s disease is déjà vécu, which is the persistent impression that each new encounter is merely a repetition of previous experiences.
First described in 1896, it is a “pathological form of déjà vu”. However, unlike the latter, which gives the impression that you have actually seen something happen, déjà vécu is the constant feeling of constantly reliving every event in life.

A persistent feeling of déjà vu may be a symptom of a rare disease
Scientists aren’t sure what causes déjà vico, but some think it has to do with a malfunction of the hippocampus, a part of the brain that helps convert short-term memories into long-term memories. People with this condition often do not understand what is happening to them and may develop delusion-like false beliefs to justify their perceptions.
This disease is sometimes found in neurodegenerative diseases such as Alzheimer’s disease, and in fact, tests on patients with this condition showed signs of Alzheimer’s disease in the brain, such as a low level of the protein amyloid beta 42, but high levels of tau protein, both of which are indicators. Of the disease.
