Alzheimer’s disease (AD) is a devastating neurodegenerative disorder with polygenic and multifactorial inheritance, determined by progressive loss of memory and other cognitive functions. AD is characterized by hallmark pathological changes such as extracellular aggregation of amyloid β (Aβ), intraneuronal neurofibrillary tangles that lead to brain atrophy and loss of neural tissue [1,2]. Alzheimer’s disease is categorized according to the age of onset as early-onset (EOAD) or lateonset AD (LOAD) [3]. And, based on family history, it is classified as sporadic (SAD) or familial Alzheimer’s disease (FAD) [4].
