Overview

Pick's disease has two meanings that are often confused:

1) Pathology: Neurologists currently use the term "Pick's disease" to mean specifically one of the pathological subtypes of frontotemporal lobar degeneration (FTLD). The pathological hallmark of Pick's disease are Pick bodies. These are spherical cytoplasmic inclusions found within neurons in affected portions of the brain.[2] They cause neurons to swell, taking on a "ballooned" appearance. Pick bodies contain the protein Tau, and hence the disease is also referred to as a tauopathy (along with progressive supranuclear palsy, corticobasal degeneration, and others).

2) Syndrome: Pick's disease is also the old name for the clinical syndrome frontotemporal dementia (FTD). Some neurologists now avoid this use of the term, however, because it is not possible to distinguish between FTD caused by Pick's disease pathology (definition 1) and other FTLD processes prior to autopsy. However, it is important to note that a number of support groups for families of patients with frontotemporal dementia continue to use the name "Pick's disease" in their titles.

Note: This confusion has led some neurologists to suggest other names for FTLD. The most prominent is perhaps Kertesz' suggestion of the term "Pick Complex" to encompass not only the clinical syndromes associated with FTLD, but also the overlapping pathologic processes of corticobasal degeneration and progressive supranuclear palsy.

For more information on Pick's Disease, see the article on the pathologic process of frontotemporal lobar degeneration (FTLD) and its related clinical syndromes of frontotemporal dementia, semantic dementia, and progressive nonfluent aphasia.
