Disintegration synonym4/30/2023 Arnold Pick, who first described it in 1892) is now reserved for a specific subtype of frontotemporal degeneration associated with a kind of abnormal tau protein known as 3R tau. The accumulation of tau protein or TDP-43 protein can also be observed in other neurological disorders.Īlthough once used more broadly, the term Pick’s disease (after Dr. In about 10% of cases, a third protein, FUS, accumulates instead of tau or TDP43. The FTD clinical subtypes can also be classified as ‘tauopathies’ or TDP43-opathies, depending on which misfolded protein accumulates in the brain. In FTD these proteins are misfolded (misshapen) which leads to their inappropriate buildup within brain cells and so interfering with or disrupting the normal function of these cells. In most people, this is accompanied by a buildup of one or the other of two proteins, tau or TDP-43. Frontotemporal degeneration is caused by progressive damage and loss of nerve cells in the frontal and temporal lobes of the brain. Generally, the clinical symptoms of these disorders can be broadly grouped into three categories which display changes in behavior, language and/or motor function. The progression and the specific symptoms that develop can vary from one person to another. Affected individuals can experience gradual changes in their behavior and personality, and may have difficulties in thinking and communicating effectively. The clinical presentation of frontotemporal degeneration is diverse.
