How Would It Be to Remember Everything?

SHARE:

Adjust text size:


Psychologists have encountered a strange case - someone who can remember in exquisite detail almost everything that happened to her. Dubbed "AJ", the patient first called for help a few years ago: "since I was eleven I have had this unbelievable ability to recall my past," she wrote. She's now 36.

This is no gift, but more of a curse, as she describes the burden all these unsolicited memories - "non-stop, uncontrollable and totally exhausting". Neuroscientist James McGaugh of the University of California called this case of memory dominating one's life "hyperthymestic syndrome", from the Greek, meaning excessive remembering.

McGaugh
and his colleagues conducted several tests to determine how well she can really remember things. On one meeting for example they have asked her, without prior warning, to remember the dates of the previous 24 Easters. She managed to remember them, as well as all that she did in each day, and she only got one date wrong, being two days off. The scientists poped the same quiz two years later: she said the exact same things, except that this time she got all the dates correctly.

"She sort of has a vacuum cleaner sucking up all of the personal experiences and storing them away so that they're available", said McGaugh.

They have also conducted various formal standard tests such as an autobiographical memory test, an IQ test and autism tests. She scored perfect on the autobiographical test, average on the IQ test and showed some signs of autism. There are already known some cases of autistic individuals whose obsessive-compulsive disorder is directed toward their own person and who are capable of recall abilities similar to AJ's.

However, AJ's condition doesn't seem to be that of a typical autistic. For one thing, no autistic has ever searched for help. Moreover, unlike autistics, AJ doesn't seem to remember things using mnemonic strategies. She explained her ability by saying "I just know it".

Other scientists are still skeptical that AJ is really that different from a standard autistic. For example, cognitive neuropsychologist Stephen Christman of the University of Toledo in Ohio has said that AJ's condition might be simply the result of an obsessive focusing over her memories for hours every day, over and over again.

In order to shed more light on the matter researchers plan to use brain scans to see whether her brain really functions in some unusual way.

Interesting. I have a similar situation, but thankfully less advanced. I can remember images from when I was a baby, detail by detail, like pictures. Sometimes I walk the memory out word for word, image for image . As I got older, not knowing, I exercised it and the ability grew.

Yes, part of the ability the individual is born with, but the rest is by development. People with this "gift" should be very careful because it can be very nerve racking. I don't think it is a curse but it can be very worrisome if the individual dwell on the wrong memories. Evaluators should look into the individual's past to see if there was a trauma that caused the individual to become introverted. In some cases, an individual experiencing trauma may become introverted and observe the outer world in detail, not knowing they are developing this ability to remember everything. The individual becomes an observer of everything, sometimes participating but always collecting information. Because so much observation was done participation level was little to none. The individual over analyzes their behavior and the behavior of others to make sure it was perfect, if it wasn't, they began to relive in their memory the day. Eventually they feel weird and make others feel weird around them. What you should take away....

Don't worry about it. It's okay to let go! Watch something relaxing, listen to something relaxing. Have a hurt or offense - forgive! Don't keep reliving the past. The other people have moved on and life has moved on.

Don't agree -think about it. If you exercise anything it will get stronger and advanced over time.

Name is Demola from Nigeria. To almighty God who made me I remember everything. I told my uncle who trow me up when I was a baby what happened the night he did that. How the atmosphere was on that day. I am 24yrs old now and I still remember everything, including pictures. I still hear the music that has been played back some years ago anytime I remember. That was why I have been searching online just to make sure this is not something totally different. I remember everything, everything. During my primary School and secondary school days I don't read. All I do is attend classes and I pass my exams well because I remember all what my teacher thought us in the classroom.

I thought I was the only one with this disorder. I not only remember everything, but I can tell you what its like to be born. You can't hear at first. You associate objects, suck as a shaded hand on an individual portrait as a seperate object, not related to the individual in the portrait. A baby is highly influenced by objects on the wall. I remember getting my prints on my birth certificate. Getting stuck for a blood sample. Remembering the billboards on the way home. Even as I grew older and went to parties, if I drank too much, I would'nt remember alot, but eventually It would come back to me and be as clear as yesturday. It is a curse. I'm 41 now and I have a son with Autism. I never knew thats what caused my disorder, but this has opened my eyes up. I tell my relatives things that I remember and they never believe me. They think I got my info from my mom, my grandmother, or someone else. Fear, or nervousness will cause me to forget the order, in which certain tasks are performed, but after I calm down, or lose the fear, I can perform the task. I also still have a baby molar. There wasnt a permanent one behind it,(Known as a phantom tooth) so they just kept that one in. It's going to put me in the Guiness Book of World Records.

I believe this hyperthymnesia syndrome is real. I don't believe that it is necessary to see it only as an adjunct of autism. There are all kinds of memory conditions involving long- and short-term memory, explicit and implicit memory, etc. and for the most part none of these types involve autism as a necessary component. Although this condition appears to be extremely rare there are other people, also known to science, who display this type of total, comprehensive memory retention. I think that it is a medical condition. I think that we forget things for a reason, we are designed to forget. I can see how it would be experienced as a curse and not a blessing.

I can also remember everything in detail but not anything before the age of 2-3 I think. what I can remember is everything after this in detail, if I listen to three people talking at a lunch, I can repeat all of there words said and repatet them with the same tone.

This has helped me alot but It has also made me tell when others lie and dont belive they did and therefor I have to confront the truth with someone who knows of another.

I remember too much and spend much time trying to drown out constant reminders and memories. I wish I did not have such a memory as it is exhausting.
