Is Picks disease contagious?

Pick’s disease is not contagious and cannot be spread through physical contact, air, or any other method of transmission. It is a progressive neurodegenerative disorder caused by the accumulation of abnormal proteins in the brain, and there is absolutely no risk of transmission to family members, caregivers, or the public.

Is Pick’s disease contagious in any way?

It is important to state clearly that Pick’s disease is not an infectious condition. Because it is a form of frontotemporal dementia (FTD), it is often misunderstood by those unfamiliar with the pathology of neurodegeneration. There is no pathogen, virus, bacteria, or fungus involved in the development of Pick’s disease. Living with, caring for, or holding the hand of a loved one with Pick’s disease poses zero risk of infection to you or anyone else.

What actually causes Pick’s disease?

Pick’s disease is a rare, progressive degenerative brain disorder. It occurs when abnormal proteins, specifically tau proteins, build up inside nerve cells in the frontal and temporal lobes of the brain. These protein deposits, known as "Pick bodies," cause the brain cells to die, leading to the characteristic cognitive and behavioral changes associated with the condition. The exact trigger for why these proteins begin to misfold remains a primary focus of medical research, but it is fundamentally a biological process occurring within the patient's own brain, not an external or environmental infection.

Why is there confusion regarding the contagiousness of Pick’s disease?

Social stigma often arises from a lack of awareness regarding neurodegenerative conditions. Because Pick’s disease can lead to significant changes in personality, speech, and behavior, observers may incorrectly assume the condition is a result of an external "illness" or something that can be "caught." This misconception is harmful and can lead to the isolation of patients and their families. It is essential to recognize that Pick’s disease is a clinical diagnosis of internal cellular dysfunction, not a communicable disease.

Are there environmental triggers for Pick’s disease?

While research into the etiology of Pick’s disease is ongoing, it is not considered to be caused by environmental pathogens or infectious agents. Current clinical understanding identifies the following factors related to its development:

• Genetic Mutations: Approximately 30% to 50% of frontotemporal dementia cases have a family history, with specific mutations in genes like MAPT, GRN, and C9orf72 being identified in some instances.


• Protein Misfolding: The hallmark of the disease is the abnormal aggregation of tau protein, which is an intrinsic biological process.


• Sporadic Occurrence: In the majority of cases, Pick’s disease occurs spontaneously without a clear family history or known environmental cause.

Next steps

• Consult a neurologist or a specialist in memory disorders to confirm a diagnosis and discuss the specific pathology of Pick’s disease.


• Connect with the 19 community members on DiseaseMaps.org who have shared their experiences to find support and reduce the isolation often felt by caregivers.


• Educate friends and family members by sharing reliable, science-based information to dispel myths regarding the "contagious" nature of the condition.


• Reach out to organizations like the Association for Frontotemporal Degeneration (AFTD) for resources on managing the behavioral aspects of Pick’s disease.
