HMN 2025: Who is The forgotten pioneer of Alzheimer’s illness analysis

Ever heard of Fischer’s illness? No? Maybe that’s not stunning, as a result of it does not exist. But it may have. In truth, the illness we now know as Alzheimer’s illness would possibly simply as simply have been referred to as Fischer’s illness or Alzheimer-Fischer illness.

Back in 1907, Dr. Oskar Fischer revealed detailed analysis on what we now acknowledge as Alzheimer’s illness. Fischer described instances of older individuals who had cognitive signs of their lifetime and famous tiny plaque-like buildings and fibrous tangles of their brains after their loss of life.

These adjustments have been the identical as these noticed by Alzheimer at across the identical time. But in contrast to Alzheimer’s temporary two-page publication highlighting this new illness in a single particular person, Fischer’s work, published in 1910, was a meticulous and wide-ranging study—spanning greater than 100 pages—together with a number of folks he investigated. So why have we by no means heard of him?

In my new ebook, “Tangled Up: The Science and History of Alzheimer’s Disease,” I try and reply this query.

A promising thoughts from Prague

But earlier than we get to why Fischer was forgotten, let us take a look at who he was.

Oskar Fischer was born in 1876 in a small city close to Prague, a part of the German-speaking minority in what’s now the Czech Republic. After learning drugs in Strasbourg and Prague, he started working on the German University of Prague’s Department of Psychiatry.

Fischer’s profession flourished beneath the management of Professor Arnold Pick—one other lesser-known scientific large. Pick was the primary to explain a distinct type of dementia, now referred to as frontotemporal dementia. It was on this forward-thinking educational setting that Fischer started his analysis into dementia.

Fischer wasn’t working in isolation. At the time, different medical doctors had additionally observed uncommon plaques within the brains of individuals with dementia. Researchers like Paul Blocq and Georges Marinesco in Paris, Emil Redlich in Vienna and Koichi Miyake in Tokyo had all seen comparable options.

But Fischer, like Alzheimer, went a step additional: he recognized not solely plaques but additionally twisted protein fibers—now referred to as tau tangles—that disrupt the mind’s operate. This mixture continues to be central to how we outline Alzheimer’s illness right this moment.

But if each males made this necessary discovery, why is just one title remembered?

There are two theories as to why Fischer has been forgotten. One is that Fischer believed these mind adjustments have been particular to a sort of dementia referred to as presbyophrenia, which was thought to have an effect on individuals who confirmed uncommon cheerfulness and confusion in outdated age.

He might have restricted his personal findings by tying them to this slender prognosis. Indeed, within the Nineteen Twenties it was realized that presbyophrenia was not a separate illness however merely how sure folks with dementia introduced—and the time period was not used anymore.

Another issue is perhaps politics and affect. Alzheimer had a strong supporter: Emil Kraepelin, some of the influential psychiatrists of the time, who Alzheimer labored for. Kraepelin included Alzheimer’s work in his bestselling textbook and named the {condition} after him, serving to to cement Alzheimer’s title in medical historical past.

There’s no document displaying whether or not Kraepelin knew of Fischer’s comparable discoveries. If he did, he by no means acknowledged them in his textbook.

Despite his scientific achievements, Fischer’s educational profession stalled. In 1919, he was denied a everlasting college place, regardless of his groundbreaking work. He opened a non-public practice in Prague and continued to show, however with out the popularity he deserved.

A tragic finish

Then got here the darkest chapter of his life. In 1941, in the course of the Nazi occupation, Fischer was arrested by the Gestapo. He was imprisoned at Theresienstadt (now Terezín), a ghetto and transit camp for Jews and political prisoners. It’s unclear why he was focused—maybe for his Jewish ancestry or his earlier communist activism. He died there in 1942.

Oskar Fischer’s story is a reminder that scientific discovery is never the work of 1 lone genius. It’s constructed on shared concepts, collaboration, and sometimes forgotten contributors.

It’s considerably just like Charles Darwin and Alfred Russell Wallace describing the idea of evolution on the same time however most solely keep in mind Darwin now. While Alois Alzheimer actually made necessary observations, Fischer’s position in defining this devastating illness was simply as vital.

Maybe it is time we remembered Oskar Fischer and gave him the credit score he so rightly deserves.
