Etiology
However, much more dissections into the causative pathways are needed to get a full picture of the etiology. [annalsofian.org]
Thus, the evidence presented here suggests that variation at rs5848 does not contribute to the etiology of FTLD in the Dutch population. [journals.plos.org]
Etiology Worldwide, frontotemporal lobe dementia with motor neuron disease (FTD/MND) is a sporadic condition with an unknown etiology. [emedicine.medscape.com]
Especially, the relatively weak correlation between clinical diagnosis and underlying genetic etiologies is complicating strategies to define inclusion criteria to maximize the power of GWASs by enriching for a limited number of susceptibility genes. [neupsykey.com]

Pathophysiology [ 1, 3 ] There is atrophy of the frontal and temporal lobes. Distribution is lobar, rather than the diffuse atrophy of Alzheimer's disease. There may be loss of neurons or gliosis but no increase in plaque formation. [patient.info]

Most mutations in the GRN gene prevent any granulin from being produced from one copy of the gene in each cell. As a result, cells make only half the usual amount of granulin. [ghr.nlm.nih.gov]
