Who was Jimmie G. from The Man Who Mistook His Wife for a Hat? What made Jimmie G.’s case study on Korsakov’s syndrome so unique?

Jimmie G. was one of psychologist Oliver Sacks’ patients who suffered from Korsakov’s syndrome. Jimmie G.’s was very similar to ten-second-Tom from the movie 50 First Dates in that his memory of the last 30 years was wiped and he was stuck in an eternal present.

The Memoryless Jimmie G.

Jimmie G. was a patient whom Oliver Sacks first met in 1975. This man likely suffered from the neurological impairment known as Korsakov’s syndrome, a condition caused by alcohol-related damage to the mammillary bodies in the brain. Korsakov’s syndrome impairs short-term memory and causes retrograde amnesia—the inability to recall memories. 

The most recent memories tend to be those most severely impacted, with patients forgetting people they met and events they witnessed mere minutes before. Sometimes, the memory loss extends backward in time, eating up memories further and further back until only the most distant remain. The worst sufferers of Korsakov’s syndrome paradoxically become trapped in the past, while at the same time living in an inescapable present. This was the tortured psychic state in which Sacks first encountered Jimmie G.

Living in the Past

One of the first things that struck Sacks was Jimmie’s excellent long-term memory. He could recall his childhood in Connecticut; the homes he’d lived in (even their phone numbers); his interest in math and engineering as a high school student; and his time in the US Navy, where he’d worked as a radio operator during World War Two. 

But something curious happened when Jimmie talked about his Navy days. He switched to the present tense and began talking about his plans for what he was going to do when he was discharged from service in the war. He spoke of the death of President Franklin Roosevelt and the Allied victory in the war as though they were current events. Sacks realized that Jimmie still thought it was 1945 and that he was still a 19-year-old sailor. In reality, it was 1975 and he was nearly fifty years old.

When Sacks presented Jimmie with a mirror and asked him if the face he saw looked like that of a 19-year-old, Jimmie recoiled in horror, unable to understand what he was looking at. It temporarily shook his sense of identity to the core. 

An Eternal Present

Luckily for Jimmie, he forgot the entire matter of the mirror a few minutes later. For, in addition to being stuck in the past, Jimmie was also stuck in an eternal present, having almost no short-term memory. He was good at solving puzzles, but only those that could be done within seconds or minutes. He was unable to do anything that took longer because he would forget the task he was engaged in. 

Further, anything said to him would be forgotten in a matter of seconds, although sometimes he could show faint echoes of short-term memory. After Sacks stopped doing memory exercises with Jimmie and resumed them a few minutes later, Jimmie reported vaguely remembering performing similar exercises with a doctor “a while back,” but did not remember that it had been Sacks and that “a while back” was mere minutes before. His condition had rendered every moment of his existence devoid of temporal meaning and context.

After looking into Jimmie’s case history further, Sacks discovered that he had actually been in the Navy until 1965 and had been mentally competent throughout the entire period of his service. Sacks made contact with Jimmie’s brother, who told him that around 1970, Jimmie had suffered some sort of break, began drinking heavily, and almost entirely blotted out his post-1945 memories. When the brother went to visit Jimmie, Jimmie was unable to recognize him.

The Indestructible Spirit

An essential piece of Jimmie (or whoever he may once have been) was missing and probably gone forever. He told Sacks that he didn’t feel miserable but that he didn’t enjoy life either, and said, hauntingly, “I haven’t felt alive for a very long time.”

But after consulting with the great Russian neuropsychologist Alexander Luria, Sacks resolved to help Jimmie regain some semblance of his humanity. Luria reminded Sacks that the self consists of more than just the memories of past events. Even someone as severely impaired as Jimmie still possessed feeling, emotion, and a sense of the sublime.

Sacks moved Jimmie to a facility where he was cared for by a team of doctors and nurses. Jimmie never truly came to recognize anyone at this facility, though he did come to familiarize himself with the setting, managing to navigate the halls and find his way to and from his room. He was capable of having emotionally significant visits with his brother, whom he still loved, though Jimmie, thinking his brother was in his 20s, could not explain why he looked so old for his age. These meetings were deeply poignant—Jimmie’s brother was his only link between his disconnected present and the past in which he still imagined himself to be living. 

But some indestructible element of Jimmie’s being managed to overcome his impairment and even thrive. When Jimmie went to church and participated in the Mass, he was clearly moved spiritually. His disorder was an advantage here because he was able to connect to God and remain completely in the moment. He could also follow and enjoy the rhythms of music and drama. Apparently, there were parts of Jimmie—perhaps the soul or the spirit—that even Korsakov’s could not destroy. The mind may have been irreparably damaged, but the soul could still be uplifted by music, art, and communion.
