I Think Im Having Deja Vu Again
A foreign case of deja vu, once more and once more and again.

Trapped in a time loop: That's how one human being felt because of his recurring episodes of deja vu. Dissimilar the vague, fleeting sensation nigh people experience in deja vu, his episodes were persistent and long.
The 23-year-old British man started to have "frightening" episodes of deja vu soon afterward starting college, said researchers who detail his unusual instance in a new written report. For minutes, and sometimes even longer, he would feel that he was reliving experiences. The episodes grew in intensity and became debilitating.
"Rather than merely the unsettling feelings of familiarity which are normally associated with deja vu, he complained that it felt like he was actually retrieving previous experiences from memory, not just finding them familiar," the researchers said.
Three years after the experiences began, the fellow could no longer fifty-fifty lookout man TV or read the paper considering he would accept a disturbing feeling that he had encountered the content before, the researchers said.
The haunting awareness was stronger than just a feeling of familiarity. The man said he felt that at every present moment, he was reliving the past.
What made the case even more peculiar was that the man didn't endure from any of the neurological atmospheric condition previously reported in people who frequently experience deja vu. Instead, he suffered from anxiety, suggesting that anxiety disorders could be more related to deja vu than previously thought, according to the written report, published December. 8 in the Periodical of Medical Instance Reports.
A faulty memory system?
Scientists have yet to detect a consummate explanation for deja vu, which is French for "already seen," merely a popular idea is that the simulated sensation of familiarity is the result of a failure in the encephalon'southward memory system, which resides in the temporal lobe of the brain.
"Most explanations of deja vu suggest that it's a phenomenon that arises from activeness within the temporal lobe. Some kind of mistimed firing of neurons, perhaps — a temporary glitch in our processing of incoming data," said Christine Wells, a psychologist at Sheffield Hallam University in the United kingdom of great britain and northern ireland who co-authored the study of the homo's example.
"A central structure within the temporal lobe is the hippocampus, which is heavily involved in retention," Wells said. "We have every reason to believe that's the area that's involved in deja vu."
In fact, although almost anyone can have an episode of deja vu every once in a while, more-frequent and more than-intense forms of the phenomenon are unremarkably seen in people who have seizures in the temporal lobe, a condition called temporal lobe epilepsy.
In this human being'south example, doctors looked for signs of seizures, but neurological examinations, including EEGs (electroencephalograms) and brain scans, didn't turn up annihilation. His encephalon action, as far equally doctors could measure out, looked normal. And a set of psychological tests of his memory didn't reveal any major problem, either.
Might it be feet?
Although the researchers didn't discover neurological clues that could explain this homo's deja vu, it is possible that they missed some signs, Wells said. The available technologies may not be sophisticated enough to pick upwards on what could be very subtle differences in the encephalon, she said.
The other explanation for the man's chronic deja vu is his anxiety disorder.
"A lot of the previous inquiry has focused — quite rightly — on temporal lobe epilepsy," Wells said. "But information technology is possible that at that place are other disorders, such as feet disorders, in which people experience deja vu slightly more ofttimes than normal."
The young man'southward anxiety was so severe that he had to take a short break from college, and that's when his deja vu began. These episodes acquired him fifty-fifty more than anxiety and distress, perhaps creating a barbarous cycle, the researchers said.
At one signal, the deja vu became fairly continuous — this happened right after the man took the hallucinogenic drug lysergic acid diethylamide (LSD), he told the researchers.
Nonetheless, the example of a single man cannot show that there's a link between anxiety and deja vu, the researchers said. But the case raises the question, and it should be studied further, they said.
