Abstract
Background: Dementias and all related neurodegenerative diseases of the Central Nervous System (CNS) are a current issue arousing a great deal of interest in the international scientific community. This is due to the increasing number of patients suffering from these diseases. These pathologies represent a serious problem, not only concerning the quality of life of the patient, but in addition, the enormous economic efforts that society has to do for their treatment. There are currently a few strategies that are available in order to prevent the progression or to mitigate symptoms of the aforementioned diseases. This consideration is particularly true if we consider the specific pathology of Alzheimer's Disease (AD).
Methods: We performed a literature search for peer-reviewed articles using different databases, such as PubMed or Scopus, and exploiting different keywords and different logical operators.
Results: Ninety-eight papers were included in the review. Four papers give an overview of the background of the dementias all over the world. The remaining papers are focused on new possibilities of treatment with natural and semi-synthetic compounds for AD.
Conclusion: The aim of this review is to give an overview of new and promising natural products and semi-synthetic compounds which could represent a source of “lead compounds” for the development of new potential drugs that could be a valid therapeutic strategy for the treatment of this pathology
Keywords: Dementia, Alzheimer's disease, beta amyloid, CNS, natural products, semi-synthetic compounds.
