Currently, about 50 million people suffer from Alzheimer's disease, and this number will only increase over time. There are only four clinically approved drugs to treat this pathology, which include acetylcholinesterase inhibitors (Rivastigmine, Donepezil, and Galantamine) and one N-methyl-D-aspartic acid receptor antagonist (memantine). Although these drugs have a therapeutic effect by improving the cognitive, functional, and behavioral characteristics of patients, they still relieve symptoms of the disease rather than manifest the links of pathogenesis, including β-amyloid precursor protein and hyperphosphorylated tau protein formed during the cleavage of amyloid precursor protein. This group of drugs also has a number of undesirable effects on the gastrointestinal tract, cardiovascular system and nervous activity. In this regard, new drugs are being developed now, directed against β-amyloid and affecting to reduce its production, aggregation, not allowing it to form plaques, the use of immunization method. There is also hyperphosphorylated tau protein, which is either not allowed to form or is immunized against. In addition to these methods, there are no less interesting ways to fight, such as the use of heat shock inducers, to activate the necessary chaperone family, or to reduce neuroinflammation by inhibiting tumor necrosis factors and using nutraceuticals. But, unfortunately, a large number of drugs cannot yet pass all 3 stages of clinical trials while maintaining their original therapeutic properties and without acquiring undesirable effects. That said, many drugs are either the basis for future drugs or are still participating in clinical trials themselves, showing encouraging results.
