How Did Henry Molaison Cause Brain Injuries?

Decent Essays

Brain injuries, though more common than one might think, don’t always lead to serious damage for a lifetime. Even less likely was Henry Molaison, who became one of the world’s most famous brain patients after the removal of his hippocampi in order to stop his constant and severe seizures destroyed his ability to create memories. Twenty-seven-year-old Henry Molaison, more often referred to as H.M., and his parents had a tough decision to make the August of 1953 (Ogden). When Molaison was only seven years old, a bicyclist hit him and knocked him out for several minutes, leaving a large gash on the side of his forehead. It was that accident that caused him to develop seizures, mild at first, but growing in severity. When he was sixteen, he had his first tonic-clonic seizure, or one that affects the entire brain, and from that day on, he had ten or more of them per day. As one might expect, it made high school difficult, and he dropped out once due to teasing (Dittrich). H.M. eventually went to a different high school, and it took until he was twenty-one before he could get his diploma because of the severity of his seizures. Even his jobs at Ace Electric Motor Company and Royal Typewriter became too dangerous to continue, so he spent most …show more content…

He could also learn new skills over time, though he wouldn’t remember ever being able to do them (Holt/Corkin). Suzanne Corkin, a neuroscientist who worked with H.M. for five decades also recalls that H.M. could recognise her—he mistakenly thought from high school—but not know who she was. This showed that despite losing his ability to retain memories, he could still become familiar with names and faces, even if he couldn’t remember who they
