With the increase in life expectancy registered in the past few decades, the prevalence of various medical conditions related to aging has been observed, such as dementia and related neurodegenerative conditions. The number of patients afflicted with these conditions is expected to significantly increase in the coming years. The growing social impact of dementia underlines the need for research aimed at identifying and better understanding this type of condition. Among neurodegenerative diseases, amyloidogenic diseases, in particular Alzheimer's disease (AD), are currently the most common form of dementia. Over the years, several hypotheses have been raised regarding the etiology of AD, such as the cholinergic, glutamatergic, amyloid cascade, oligomeric, metallic and diabetes type 3 hypotheses. Unfortunately, no cure is yet available for this disease, only drugs that aid in controlling the symptoms. This review article conducts a comprehensive approach of the main etiological hypotheses of AD, as well as the treatment prospects associated with each hypothesis.
