There are three main histological subtypes found at post-mortem: FTLD-tau, FTLD-TDP, and FTLD-FUS. In rare cases, patients with clinical FTD were found to have changes consistent with Alzheimer's disease on autopsy. [41] The most severe brain atrophy appears to be associated with behavioral variant FTD, and corticobasal degeneration. [42]
Frontotemporal lobar degeneration; Neuropathologic analysis of brain tissue from FTLD-TDP patients. Ubiquitin immunohistochemistry in cases of familial FTLD-TDP demonstrates staining of (a) neurites and neuronal cytoplasmic inclusions in the superficial cerebral neocortex, (b) neuronal cytoplasmic inclusions in hippocampal dentate granule cells, and (c) neuronal intranuclear inclusions in the ...
Alternatively, diseases exhibiting tau pathologies attributed to different and varied underlying causes are termed 'secondary tauopathies'. Some neuropathologic phenotypes involving tau protein are Alzheimer's disease , frontotemporal dementia , progressive supranuclear palsy , and corticobasal degeneration .
[12] [17] [18] Detachment of tau from microtubules causes the neuron to lose its ability to sustain itself and thus ultimately it loses function. Hyper-phosphorylation of tau protein was initially thought to be caused by Aβ 42 but since PART cases generally lack senile plaques, other causes were investigated.
However, relatives of a person with any form of frontotemporal lobar degeneration (FTLD), including PPA, are at slightly greater risk of developing PPA or another form of the condition. [6] In a quarter of patients diagnosed with PPA, there is a family history of PPA or one of the other disorders in the FTLD spectrum of disorders.
Other degenerative pathologies that can cause corticobasal syndrome include: Alzheimer's disease; Pick's disease with Pick bodies; Lewy body dementias; Neurofilament inclusion body disease; Creutzfeldt–Jakob disease; Frontotemporal degeneration due to progranulin gene mutation; Motor neuron disease‐inclusion dementia.

In other words, the symptoms of LATE are similar to those of Alzheimer's disease. The acronym LATE stands for L imbic-predominant A ge-related T DP-43 E ncephalopathy. “ Limbic ” is related to the brain areas first involved, “age-related” and the name “LATE” itself refer to the onset of disease usually in persons aged 80 or older.
C9orf72 (chromosome 9 open reading frame 72) is a protein which in humans is encoded by the gene C9orf72.. The human C9orf72 gene is located on the short (p) arm of chromosome 9 open reading frame 72, from base pair 27,546,546 to base pair 27,573,866 (GRCh38).
