into just how difficult life can be for people who have this ability. k. anders ericsson of florida state university does not believe that sufficient evidence exists to suggest that the skills of price and williams need additional explanation: "our work has pretty much concluded that differences in memory don't seem to be the result of innate differences, but more the kinds of skills that are developed." as the condition has become better known, more people claiming to have hyperthymestic abilities have emerged. in the aftermath of the 2006 neurocase publication alone, more than 200 people contacted mcgaugh; however, only a handful of cases were determined to be actual cases of hyperthymesia. the second verified case was brad williams, the third was rick baron, and in 2009, bob petrella became the fourth person diagnosed with hyperthymestic syndrome. on december 19, 2010, actress marilu henner was featured on the u.s. television program 60 minutes for her superior autobiographical memory ability. henner claimed she could remember almost every day of her life since she was 11 years old. the show was initially pitched as a story featuring hyperthymestic violinist louise owen, but the reporter lesley stahl volunteered her friend henner as having a similar ability. in june 2012, the case of h.k. derryberry was reported, a blind 20-year-old man who could clearly recall every day of his life since the age of about 11. derryberry had been born at 27 weeks, weighing just over 2 pounds (0.91 kg) and was in neonatal intensive care for 96 days. a severe brain hemorrhage was the likely cause of cerebral palsy, and his prematurity resulted in congenital blindness. he told researchers that his memories are rich in sensory and emotional details, regardless of whether they are from years ago or yesterday. about 90% of his memories are in the first person, compared with an average of 66% in the general population. brandon ally and his team, at vanderbilt university, nashville, tennessee, conducted a series of tests with the subject, including a brain scan that was compared with 30 age-matched controls. his brain was smaller than average (probably a result of his premature birth at 27 weeks). his right amygdala, however, was 20% larger, with enhanced functional connectivity between the right amygdala and hippocampus and in other regions. in 2016, hk's remarkable life story was published by harpercollins christian publishing in a book entitled the awakening of hk derryberry: my unlikely friendship with the boy who remembers everything, which details his medical condition. it was written by his mentor jim bradford with the help of andy hardin. 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. hayman is the first british person to be identified as possessing this ability, and he views it positively. when hayman's brain was scanned by a team led by professor giuliana mazzoni at the university of hull, whilst he was prompted to remember a series of dates, a series of "visual areas" of the brain were activated, with much greater speed than would be expected in normal brain function. potential problems with total recall were illustrated. the documentary also featured 62-year-old tv producer bob petrella, whose memory has allowed him to catalogue the events from his "favorite days" over many years into an extensive scrapbook. in march 2015, markie pasternak of green bay, wisconsin was diagnosed as the youngest person to be living with hsam. born in 1994, pasternak remembers every day of her life since february 2005. she was featured on 60 minutes australia in august 2016 with rebecca sharrock. in january 2016, painter and polymath nima veiseh was featured by the bbc for his use of hyperthymesia to create paintings that were said to only be producible with vast memories of art pieces, although a paper published in the journal memory in 2022 claimed that having hyperthymesia does not increase one's creative thinking. veiseh claimed he could remember almost every day of his life since he was 15 years old, and that his ability to synthesize time and an "encyclopedic knowledge of the history of art" enabled him to create wholly unique visions on canvas. in march 2016 npr examined further veiseh's exploration of time and the human experience through art. in april 2017, rebecca sharrock of brisbane, australia became known as a person who claims to recall even circumstantial details of every day of her life from her 12th day of life onward. discussing her hyperthymesia with bbc world service, sharrock revealed she was supporting two research projects – one with the university of queensland and another with the university of california – to understand how a greater knowledge of hyperthymesia can support alzheimer's disease research, particularly in repairing the degeneration of the hippocampus. scans conducted during the studies showed that sharrock's brain exhibited a heightened connection between the conscious and sub-conscious parts of her brain, which may aid easier memory recall – particular for events that took place earlier in life. in december 2017, a man named joey degrandis was verified as having hsam by james mcgaugh and subsequently featured in an article in the magazine time. degrandis also reports having poor short-term memory, indicating that hsam does not necessarily improve one's short-term memory abilities. a 63-year-old man, anonymized as "the amazing memory man" (mm) was featured in a paper by neuropsychology in march 2018, where is it reported that he "appreciates that his memory for personally experienced life events and general knowledge are both exceptional, whereas his imaging the future is only average" (after scoring 123 on episodic, 123 on semantic, 112 on spatial, and 91 on future remembering memory types, all with a mean of 100). in october 2018, it was reported that teenager tyler hickenbottom, who is an identical twin, had the condition, which allowed him to "remember every day of his life like it was yesterday". books in the 1942 short story "funes the memorious" by jorge luis borges, the protagonist suffers a head injury after which he gains the ability to remember every detail of what he experiences, but comes to view this as a curse. the condition may not technically be an example of hyperthymesia, but shares some features. in the 1980 series the book of the new sun by gene wolfe, the protagonist remembers everything he has ever seen starting from infancy. he describes his memories as being so vivid that he is capable of re-living anything he has experienced whenever he chooses to do so. in a 2011 manga by kohske called gangsta, the main character, worick arcangelo, is said to have hyperthymesia, which he uses to help police identify murder victims. in the 2015 novel memory man by david baldacci, the protagonist, amos decker, has hyperthymesia. in the book, a mystery-crime scene-thriller with graphic scenes, decker uses his perfect memory brought on by a traumatic hit in football to solve the murder of his wife and child, and the school shooting connected to it. decker recalls his memories as a "dvr", just playing when it wants to, or being rewound and played forward by conscious thought. in the novel "the portraits of gods" by john kingston, the protagonist, bryan wakefield, suffers a mid-life crisis brought upon, in part, by his struggles with hyperthymesia, which includes memories of a long-lost love. in the book "twisted love" by ana huang, the protagonist is said to have hyperthymesia. film in the 2014 film the dark place, the protagonist of the story, keegan dark, has hyperthymesia. keegan uses it to solve the mystery at the heart of the story. his hyperthymesia memories are visually depicted in the movie as "screens" appearing to keegan, often in an overwhelming and distressing manner. unforgettable (american tv series)
