This review covers nanotherapeutic strategies for solving the global problems associated with Alzheimer's disease (AD). The most dramatic factor contributing humanistic, social and economic urgency of the situation is the incurability of the disease, with the drug intervention addressing only AD symptoms and retarding their progress. Key sources behind these challenges are the inability of the early diagnosis of AD, the lack of comprehensive information on the molecular mechanism of the pathogenesis, the bloodbrain barrier obstacles, and the insufficient effectiveness of currently available drugs and therapeutic strategies. The application of nanocarriers allows part of these problems to be solved, together with the improvement of drug bioavailability, prolonged circulation, and overcoming/bypassing the biological barriers. To this date, numerous types and subtypes of nanocarriers are developed and reviewed, the majority of which can be adapted for the treatment of various diseases. Therefore, herein, nanotherapy strategies are specifically categorized in term of the administration routes of AD medicines, with the noninvasive, i.e., transdermal, oral, and intranasal routes emphasized. Further, benefits/ limitations of various nanocarriers are discussed, and perspectives of their application are highlighted.
