What is Picks disease

Pick’s disease, now more commonly referred to as a form of frontotemporal dementia (FTD), is a rare, progressive neurodegenerative disorder characterized by the accumulation of abnormal proteins in the frontal and temporal lobes of the brain. It primarily affects personality, behavior, and language skills, leading to a gradual decline in cognitive function that distinguishes it from more common conditions like Alzheimer’s disease.

What exactly is Pick’s disease?

Pick’s disease is a localized form of dementia that specifically impacts the areas of the brain responsible for impulse control, social behavior, and language processing. Unlike Alzheimer’s disease, which often begins with memory loss, Pick’s disease typically manifests first as significant changes in character, social appropriateness, or the ability to speak and understand words. As the disease progresses, the brain tissue in these specific regions shrinks (atrophy), leading to a decline in overall executive function.

How does Pick’s disease affect the body?

The primary impact of Pick’s disease is neurological. The buildup of abnormal proteins, known as "Pick bodies," interferes with the healthy function of neurons in the frontal and temporal lobes. Because these regions govern our "filter," empathy, and complex reasoning, patients may experience profound shifts in their personality. Physically, as the condition advances, patients may develop motor difficulties, muscle rigidity, or challenges with coordination, though these symptoms are often secondary to the primary cognitive and behavioral changes.

Who is typically affected by Pick’s disease?

Pick’s disease is considered a rare condition, though precise prevalence numbers are difficult to determine because it is frequently underdiagnosed or misdiagnosed as other forms of dementia. Current clinical data suggests the following:

• Age of Onset: It most commonly presents in individuals between the ages of 45 and 65, making it a "younger-onset" dementia.


• Gender Distribution: While some studies suggest a slight prevalence in men, it is generally considered to affect both genders equally.


• Geographic Factors: There is no evidence suggesting that Pick’s disease is tied to any specific geographic location or ethnic group.

How does it differ from other forms of dementia?

Differentiating Pick’s disease from other neurodegenerative conditions is critical for proper care. The key differences include:

1. Early Symptom Profile: Memory is often preserved in the early stages, whereas behavioral changes or language deficits (aphasia) are the hallmark signs.


2. Pathological Markers: The presence of Pick bodies (tau-protein aggregations) is the definitive diagnostic feature, which is distinct from the amyloid plaques and tau tangles found in Alzheimer’s disease.


3. Progression: The disease often follows a more rapid trajectory than typical age-related cognitive decline.

Next steps

• Consult a neurologist or a behavioral neurologist specializing in neurodegenerative disorders for a comprehensive clinical assessment.


• Consider genetic counseling if there is a known family history of dementia, as some forms of frontotemporal degeneration are hereditary.


• Join the Pick’s disease community at DiseaseMaps.org to connect with the 19 current members who are sharing their lived experiences and coping strategies.


• Discuss participation in clinical trials or research registries to contribute to the growing body of knowledge regarding this rare condition.
