Description : Frontotemporal dementia (FTD) refers to a clinical manifestation of the pathologic
finding of frontotemporal lobar degeneration (FTLD). FTD, the most common subtype
of FTLD, is a behavioral variant characterized by changes in social and personal conduct
with loss of volition, executive dysfunction, loss of abstract thought, and decreased
speech output. A second clinical subtype of FTLD is 'semantic dementia,' characterized
by specific loss of comprehension of language and impaired facial and object recognition.
A third clinical subtype of FTLD is 'primary progressive aphasia' (PPA), characterized
by a reduction in speech production, speech errors, and word retrieval difficulties
resulting in mutism and an inability to communicate. All subtypes have relative preservation
of memory, at least in the early stages. FTLD is often associated with parkinsonism
or motor neuron disease (MND) resembling amyotrophic lateral sclerosis (ALS; 105400)
(reviews by Tolnay and Probst, 2002 and Mackenzie and Rademakers, 2007). Mackenzie
et al. (2009, 2010) provided a classification of FTLD subtypes according to the neuropathologic
findings (see PATHOGENESIS below). - Clinical Variability of Tauopathies Tauopathies
comprise a clinically variable group of neurodegenerative diseases characterized neuropathologically
by accumulation of abnormal;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the microtubule-associated tau protein gene (MAPT, 157140.0001); Caused by mutation in the presenilin-1 gene (PSEN1, 104311.0023);
