Alzheimer’s disease (AD) is a senile decay of neurons. Extracellular beta-amyloid accumulation and intracellular tau hyperphosphorylation are two key characteristics of the pathogenesis of AD. Because of the multifactorial character of many disorders, new medicine-based psychoactive treatments have had limited success. As a result, there is a growing demand for innovative products that can target different receptors and improve behavioral abilities on their own or in combination with established treatments. In recent years, both industrialized and developing countries have seen a surge in herbal products based on traditional knowledge. According to recent research, bacoside and its congeners can dramatically lower the build-up of amyloid-β plaques, which are a defining feature of AD. This decrease is explained by bacoside's capacity to regulate β-secretase activity, which lowers the production of amyloid-β. Ayurveda is a medical science that focuses on the use of naturally occurring plant products to treat ailments. Many neuroprotective plants are said to be found in Ayurveda. The key physiological dysfunctions linked to tau aggregates, which contribute to dementia and behavioral inconsistencies, include the formation of reactive oxygen species, augmented neuronal swelling, and neurotoxicity. Here, we have focused on bacopa as an anti-Alzheimer medication. Bacoside A, Baccoside B, Apigenin, Betullinic acid, etc. are the pharmacologically active congeners of Brahmi belonging to several chemical families.

Whether an antipsychotic is termed typical or atypical is related to the xenobiotic’s propensity to cause extrapyramidal side effects. However, with a few exceptions, drugs of both classes of antipsychotics are known to cause hyperprolactinemia. As many breast cancers are responsive to prolactin concentrations, the persistent increase in prolactin of the antipsychotics has implications for public health and carcinogenesis. The objective of this study was to review the extant literature on hyperprolactinemia due to antipsychotics, and to determine the risk imposed by those drugs on human breast cancer. A summary risk of breast cancer with use of any antipsychotic was found to be 1.19 (95 % confidence interval 1.10–1.30). When limiting usage of antipsychotics to 5 or more years, the summary risk increased to 1.26 (95 % confidence interval 1.12–1.43). And when limited to those studies who evaluated only those medications with the greatest increase in prolactin, the risk increased to 1.59 (95 % confidence interval 1.37–1.85).
