Insets show TDP-43 positive neuronal cytoplasmic inclusions (Inset A--in dentate granule cells) and wispy non-tapering cellular processes stained for TDP-43 protein (Inset B--in CA1). LATE is a term that describes a prevalent medical condition with impaired memory and thinking in advanced age, often culminating in the dementia clinical syndrome ...
Abnormal TAR DNA-binding protein 43 (TDP-43) deposits were found on autopsy in the nerves of some with FOSMN. Abnormal TDP-43 deposits are seen in 98% of cases of ALS and are also commonly found in frontotemporal dementia. The pathological TDP-43 deposits suggest a neurodegenerative cause of FOSMN with pathophysiology closely linked to that of ...
Frontotemporal dementia (FTD) is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]

The symptoms of frontotemporal dementia are primarily related to language or behavior, per UCSF. These include: Apathy or unwillingness to talk. Change in personality, such as being more depressed.
TDP-43 is 414 amino acid residues long. It consists of four domains: an N-terminal domain spanning residues 1–76 (NTD) with a well-defined fold that has been shown to form a dimer or oligomer; [6] [7] two highly conserved folded RNA recognition motifs spanning residues 106–176 (RRM1) and 191–259 (RRM2), respectively, required to bind target RNA and DNA; [8] an unstructured C-terminal ...
Signs and symptoms depend on the specific disease, but motor neuron diseases typically manifest as a group of movement-related symptoms. [6] They come on slowly, and worsen over the course of more than three months. Various patterns of muscle weakness are seen, and muscle cramps and spasms may occur.
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 ...
