The progression of dementia (in Alzheimers disease) has been divided into seven stages. Frontotemporal dementias are mostly early-onset syndromes that are linked to frontotemporal lobar degeneration (FTLD),[5] which is characterized by progressive neuronal loss predominantly involving the frontal or temporal lobes, and a typical loss of more than 70% of spindle neurons, while other neuron types remain intact. In later stages, it gradually expands its area to the dorsolateral cortex and the temporal lobe. This rare brain disorder usually occurs in people without known risk factors.
