Is hyperthymesia dangerous

Hyperthymesia is an ability that allows people to remember nearly every event of their life with great precision. People may also refer to it as highly superior autobiographical memory HSAM. Hyperthymesia is rare, with research identifying only a small number of people with the ability. Studies on hyperthymesia are ongoing, as scientists attempt to understand how the brain processes memories.

According to a study , people with hyperthymesia can accurately and readily recall numerous details about events that have occurred in their life. These details can include exact dates and intricate information about previous experiences. Current research suggests that the ability is limited to autobiographical memory.

This limitation means that people can only recall information about themselves and their past personal experiences. People can retain information as either short-term or long-term memories. People with HSAM likely process short-term memories in a similar way to most other people. However, a study suggests that these individuals have better long-term memory.

HSAM is different than having a good memory. For example, people with HSAM do not use mnemonic devices to remember long strings of information. Some researchers have noted that these individuals share some characteristics with people who have obsessive-compulsive disorder OCD. For example, they may demonstrate obsessive tendencies. People with both conditions also tend to have certain structural differences in particular regions of the brain.
