All rights reserved. There is a distinction between those with hyperthymesia and those with other forms of exceptional memory, who generally use mnemonic or similar rehearsal strategies to memorize long strings of information. Their memorization of events tends to exceed their ability to memorize given facts; for example, if you told a hyperthymesiac a fact about the world, they may not remember what you said, but they will more likely remember what you wore and other details of the situation when you told them. Further research is necessary to assess the long-term effects of this. The type of memory used for this is mnemonic memory. This circuit plays a crucial role in neurodevelopmental disorders. [3] While memories are reported as vivid, they are not exact recordings of all experiences, as seen in the case of AJ:[1]. However, a hyperthymesia test is considered pointless by many experts because this is a condition you are born with. © 2005-2020 Healthline Media a Red Ventures Company. Hyperthymesia is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail. People with exceptional autobiographical memory don’t use mnemonics to memorize details of their lives. By finding out more about how memories work, scientists…, The hippocampus is a part of the brain that plays a key role in memory and how knowledge is obtained. The caudate nucleus is primarily associated with procedural memory, in particular habit formation, and is, therefore, intrinsically linked to obsessive-compulsive disorder. Flashbulb memory is like a very vivid snapshot of a moment in time or an event. In some cases, the visualizations may change or become stored as a long-term memory. However, it’s not known if these differences caused the HSAM or if they occurred because of the person’s greater use of areas of the brain associated with memory. [1] This was demonstrated by AJ's poor performance on standardised memory tests. Participants receive minimal instructions. [1] The word "hyperthymesia" derives from Ancient Greek: hyper- ("excessive") and thymesis ("remembering"). HSAM can be both a gift and a challenge. If you are diagnosed with HSAM, your doctor will work with you to develop a management plan. When a memory comes to mind, specific emotional and contextual details are written down, counted, and scored. These details can include exact dates and intricate information about previous experiences. Parker and colleagues speculated that a defective frontostriatal circuit could be responsible for the observed executive function deficits in hyperthymesia. For example, people with HSAM do not use mnemonic devices to remember long strings of information. Many people with HSAM have large collections that they’ve organized and cataloged with great care. In extensive testing, she demonstrated the ability to recall details of events that happened on specific days, spanning decades of her life.

However, a 2016 study suggests that these individuals have better long-term memory. Here are a few tips: Want to remember a specific event better? [28], In September 2012, UK's Channel 4 screened the documentary The Boy Who Can't Forget, which examined the memory of 20-year-old Aurelien Hayman from Cardiff, a student at Durham University, who remembers practically every day of his life from the age of 10.

Several traits, though, appear to be common across those affected. Like autistic savants, some individuals with hyperthymesia may also have an unusual and obsessive interest in dates. These mostly consisted of questions pertaining to specific dates and events in history. These cognitive deficiencies are characteristic of frontostriatal disorders.[1]. Hyperthymesia is the rare ability to recall nearly all past experiences in great detail. Possible ways to assess this may be through MRI scans and complex memory tests. You probably remember what you wore yesterday, but that memory will fade quickly. As there are relatively few people with hyperthymesia, there is a lack of research examining the causes. They have the ability to concentrate deeply, blocking out distractions in the environment around them.

In fact, she was not very good at memorizing anything at all, according to the study published in Neurocase.
