What is the history of Picks disease?

Pick’s disease, now clinically classified as a form of frontotemporal dementia (FTD), was first described by Arnold Pick in 1892 as a localized form of progressive brain atrophy. Over the last century, our understanding has shifted from viewing it as a rare psychiatric curiosity to recognizing it as a complex, genetically and biologically distinct neurodegenerative disorder characterized by specific protein accumulations.

Who first discovered Pick’s disease?

The medical history of Pick’s disease begins in 1892, when Arnold Pick, a professor of psychiatry in Prague, reported the case of a patient suffering from localized brain atrophy. Pick noted that the symptoms—specifically language impairment and personality changes—differed significantly from the global cognitive decline typically associated with Alzheimer’s disease. It was not until the 1920s that Alois Alzheimer and others identified the microscopic hallmarks of Pick’s disease, specifically the presence of spherical, silver-staining neuronal inclusions now known as "Pick bodies."

How has our understanding of Pick’s disease evolved?

For decades, clinicians struggled to distinguish Pick’s disease from other dementias. Historically, it was often misdiagnosed as late-onset schizophrenia or depression due to the prominent behavioral changes patients exhibited. However, the late 20th century brought a paradigm shift. Researchers discovered that Pick’s disease is not a monolithic condition but rather a specific pathology within the broader spectrum of frontotemporal lobar degeneration (FTLD). We now understand that the "Pick bodies" consist primarily of hyperphosphorylated tau protein, which distinguishes it from other forms of FTLD characterized by TDP-43 or FUS protein deposits.

What are the major milestones in the study of this condition?

The evolution of diagnostic technology has fundamentally changed how we manage Pick’s disease. Key historical milestones include:

• 1892: Arnold Pick publishes the first clinical description of lobar atrophy.


• 1926: The term "Pick’s disease" is formally coined by Hugo Spatz to honor Pick’s initial observations.


• 1990s: The development of advanced neuroimaging, such as MRI and PET scans, allows physicians to visualize the characteristic frontal and temporal lobe atrophy in living patients for the first time.


• 1998: The discovery of mutations in the MAPT (microtubule-associated protein tau) gene establishes a definitive genetic link for many familial cases.

How have genetics and technology refined our diagnosis?

Modern clinical genetics has been the most significant advancement in the history of Pick’s disease. We now know that approximately 30% to 50% of patients with frontotemporal dementia have a family history, and genetic testing can identify specific mutations in genes like MAPT, GRN, and C9orf72. At DiseaseMaps.org, we have seen 19 members join our community, reflecting the growing global effort to pool data and experiences. These modern insights have moved us away from historical misconceptions that suggested these symptoms were merely "senility," providing families with concrete biological explanations for the profound behavioral and linguistic changes their loved ones experience.

Next steps

• Consult a neurologist or a behavioral neurologist specializing in neurodegenerative disorders for an accurate diagnostic workup.


• Consider genetic counseling if there is a known family history of early-onset dementia.


• Join a dedicated support group, such as the Association for Frontotemporal Degeneration (AFTD), to connect with others navigating this journey.
