Abstract: 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.
