In addition to dementia, AD is associated with the loss of synapses [3,4], synaptic dysfunction [5], mitochondrial structural and functional abnormalities [6,7,8], microRNA deregulation [9,10], inflammatory responses [11], neuronal loss, accumulation of amyloid-beta (Aβ) [12,13] and phosphorylated tau (p-tau) [14,15,16]. Here, MAPT is linked to dementia.
