To recap, amnesia is a loss of memory, but dementia is a loss of brain function, which affects more than just memory. You can say that amnesia is one of the symptoms of dementia. Dementia is progressive, disabling and will ultimately kill you. вЂњIf you look at something for long enough the mind gets tired and it loses itвЂ™s meaning,вЂќ Moulin says.ДЄ cousin to dГ©jГ vu and jamais vu is вЂњpresque vu,вЂќ meaning вЂњalmost seen.вЂќ Presque vu is вЂњthe sensation of being on the brink of an epiphany вЂ¦ Frequently, one experiencing presque vu will say that they have something вЂon the tip of their tongue.Dementia also involves memory loss, but has many other symptoms as well. Some thought they had been tricked into thinking it was the right word for a door. When they were later asked to describe their experiences, 68% showed signs of jamais vu.ДЇor example, after writing вЂњdoorвЂќ over and over again some participants reported that вЂњit looked like I was spelling something else,вЂќ it вЂњsounded like a made-up word,вЂќ and вЂњI began to doubt that I was writing the correct word for the meaningвЂќ. He asked 92 subjects to write common words such as вЂњdoorвЂќ 30 times in 60 seconds. Moulin says his study shows itвЂ™s possible to induce jamais vu by whatвЂ™s known as semantic satiation, which occurs when the brain becomes fatigued in a specific way. Moulin also observed that a form of jamais vu known as вЂњsemantic satiationвЂќ could be induced experimentally: вЂњ when you look at a face for too long and it begins to look strange, or when youвЂ™re in a familiar place but think вЂI donвЂ™t know where I amвЂ™, for a brief, fleeting moment.вЂќДr. ItвЂ™s the sensation where you wake up in the morning and turn to the person next to you and feel that theyвЂ™re a stranger,вЂќ says Moulin. вЂњMusicians can get in the middle of playing a familiar passage. вЂњIf you stare at a word, for instance, it loses its meaning,вЂќ says Moulin, who adds that an estimated 60% of people have experienced jamais vu. But as cognitive neuropsychologist Chris Moulin has noted, itвЂ™s something people can experience fleetingly even in the absence of any underlying medical cause: What could cause jamais vu, though? How could we forget something that is so thoroughly familiar to us?Д¬ertainly some medical conditions could produce that phenomenon, such as amnesia, epilepsy, and forms of dementia. Jamais vu is more commonly explained as when a person momentarily doesnвЂ™t recognize a word, person, or place that he/she already knows. Often described as the opposite of dГ©jГ vu, jamais vu involves a sense of eeriness and the observerвЂ™s impression of seeing the situation for the first time, despite rationally knowing that he or she has been in the situation before. In psychology, the term jamais vu is used to describe any familiar situation which is not recognized by the observer. A person experiencing jamais vu might, for example, walk through their home or neighborhood and fail to recognize where they are, or encounter family members and friends but view them as strangers:

вЂњDГ©jГ vuвЂќ is a French term that literally translates as вЂњalready seen,вЂќ and opposite of that phenomenon is known as вЂњjamais vu,вЂќ meaning вЂњnever seenвЂќ - a term that describes a sense of unfamiliarity with something that should be familiar. But how many of us have pondered the question of what the opposite of dГ©jГ vu is? Nearly all of us know what dГ©jГ vu is and have experienced it ourselves. It manifests as our seemingly recognizing a place weвЂ™ve never been to before or a person weвЂ™ve never met, or вЂњrecallingвЂќ a past memory of an occurrence that is taking place in the present. вЂњDГ©jГ vuвЂќ is the eerie sensation that something - a place, a person, an event - is oddly familiar to us, even when that cannot possibly be the case.
