NIH Rare Diseases:43 Primary progressive aphasia (ppa) is a type of dementia characterized by language disturbance, including difficulty making or understanding speech (aphasia). ppa can be part of frontotemporal dementia or alzheimer disease. spatial skills and memory usually remain intact. in early stages, ppa often manifests as deficits in naming, word finding, or word comprehension. in late stages, affected individuals often become mute and lose their ability to communicate. in some cases, ppa is inherited in an autosomal dominant fashion and caused by mutations in the grn gene.ppa can be classified into three distinct variants based on language profiles, which include progressive non-fluent aphasia (pnfa), semantic dementia (sd), and the recently characterized logopenic variant (lpa). last updated: 8/22/2011

MalaCards: Primary Progressive Aphasia, also known as aphasia, primary progressive, is related to aphasia and semantic dementia. An important gene associated with Primary Progressive Aphasia is GRN (granulin), and among its related pathways are Statin Pathway and Glypican 1 network. The compounds dimyristoylphosphatidylcholine and metrifonate have been mentioned in the context of this disorder. Affiliated tissues include brain, temporal lobe and cortex, and related mouse phenotypes are pigmentation and other.

NINDS:44 Frontotemporal dementia (FTD) describes a clinical syndrome associated with shrinking of the frontal and temporal anterior lobes of the brain. Originally known as Pick?s disease, the name and classification of FTD has been a topic of discussion for over a century.
