: Alzheimer’s disease (AD) is a chronic neurodegenerative disease affecting the elderly. AD is associated with a progressive decline in memory and cognitive abilities, drastic changes in behavioural patterns and other psychiatric manifestations. It leads to a significant decline in the quality of life at personal, household as well as national level. Although AD was described about hundred years back and multiple theories have been proposed, its exact pathophysiology is unknown. There is no cure for AD and the life expectancy of AD patients remains low at 3 - 9 years. An accurate understanding of the molecular mechanism(s) involved in the pathogenesis of AD is imperative to devise a successful treatment strategy. This review explains and summarises the current understanding of different therapeutic strategies based on various molecular pathways known to date. Different strategies based on anti-amyloid pathology, glutamatergic pathway, anti-tau, neuroprotection through neurotrophic factors and cholinergic neurotransmission have been discussed. Further, the use of anti-inflammatory drugs, nutraceuticals, and dietary interventions has also been explained in the management of AD. It further describes different pharmacological and dietary interventions being used in treating and/or managing AD. Additionally, this article provides a thorough review of the literature for improving the therapeutic paradigm of AD.

Coronavirus disease (COVID-19) is the greatest pandemic of this era and has affected more than 10 million people across 213 nations. However, the etiology, management, and treatment of COVID-19 remain unknown. A better understanding of the novel virus would help in developing accurate diagnostic methods and efficacious drugs for the treatment of patients of all age groups. To control the pandemic urgently, many drugs are being repurposed and several clinical trials are in progress for the same. As cytokine storm has been observed to be one of the common mechanisms of immune response in COVID-19 patients, several drugs are under trials to control the cytokine storm. In this review, we discuss the different categories of drugs in clinical trials for the management of cytokine storms in COVID-19 patients. Hitherto, several promising candidates such as IL-1 and IL-6 inhibitors have failed to display efficacy in the trials. Only corticosteroid therapy has shown benefit so far, albeit limited to patients on ventilator support. Thus, it is crucial to seek novel strategies to combat hyperinflammation and increase survival in COVID-19 afflicted patients.
