What is the prevalence of Picks disease?

Pick’s disease, a rare form of frontotemporal dementia (FTD), is estimated to have a prevalence ranging from 15 to 22 per 100,000 individuals, though these figures are likely underestimates due to historical diagnostic challenges. It is considered a rare neurodegenerative condition that typically manifests in mid-to-late adulthood, with no significant difference in prevalence between males and females.

What is the prevalence and incidence of Pick’s disease?

Determining the exact prevalence of Pick’s disease is complex because, clinically, the term is often used interchangeably with the broader category of Pick complex or behavioral variant frontotemporal dementia (bvFTD). According to Orphanet and other rare disease registries, the prevalence of frontotemporal lobar degeneration (the family to which Pick’s disease belongs) is estimated at 15–22 per 100,000 people. Because Pick’s disease is a specific pathological subtype characterized by Pick bodies (tau-protein inclusions), its exact incidence is difficult to isolate from general FTD data. Most epidemiological studies suggest that Pick’s disease accounts for roughly 5% to 10% of all dementia cases, though it is significantly rarer in the population under age 65 compared to Alzheimer’s disease.

Who is most affected by Pick’s disease?

Pick’s disease typically presents in adults, most commonly between the ages of 45 and 65. While it can occur outside this range, it is rarely diagnosed in pediatric populations. Clinical research indicates that there is no clear gender bias; both men and women are affected at similar rates. Regarding geographic or ethnic distribution, there is currently no evidence to suggest that Pick’s disease is more prevalent in any specific population or region, though research into genetic modifiers continues to evolve.

Why is accurate data on Pick’s disease difficult to obtain?

The primary challenge in gathering precise statistics for Pick’s disease is the history of misdiagnosis. Before modern imaging (such as PET or MRI) and advanced biomarkers, many patients were misdiagnosed with psychiatric disorders or Alzheimer’s disease. Even today, confirming a diagnosis of Pick’s disease often requires post-mortem neuropathological examination to identify the characteristic Pick bodies. Consequently, many cases go unreported in national health databases. At DiseaseMaps.org, we have seen 19 individuals living with Pick’s disease join our community, providing a real-world look at the patient experience that often complements the limited clinical literature.

Factors influencing diagnosis and prevalence reporting

• Diagnostic Complexity: The need for specialized neuroimaging to distinguish Pick’s disease from other dementias.


• Clinical Overlap: Symptoms often mimic psychiatric conditions, leading to initial misclassification.


• Pathological Confirmation: True incidence is often only confirmed during autopsy, limiting "living" prevalence accuracy.


• Community Reporting: Patient-led platforms like DiseaseMaps help bridge the gap by connecting families who have received a clinical diagnosis.

Next steps

• Consult a neurologist or behavioral neurologist specializing in neurodegenerative diseases for specialized cognitive testing.


• Inquire about the latest biomarker research or clinical trials that may be relevant to frontotemporal lobar degeneration.


• Connect with the DiseaseMaps.org community to share experiences and learn from the 19 other members currently navigating a Pick’s disease diagnosis.


• Speak with a genetic counselor if there is a family history of early-onset dementia to understand potential hereditary links.
