Despite more than fifty years of intensive research on Alzheimer’s disease (AD) drug discovery, up till now only four medicines are approved by FDA for its treatment; among which three are acetylcholinesterase (AChE) inhibitors (donepezil, galantamine, and rivastigmine) and one is N-Methyl-D-aspartate (NMDA) antagonist memantine. These medications were launched during the initial research for AD but were not able to provide satisfactory results because of their limited efficacy and numerous side effects. The high-profile failure of late-stage clinical trials by prominent pharma firms for biomolecules that showed promising results in experimental models has added to the dissatisfaction of drug development research for AD in recent years. The global dementia patient population was expected to be 50 million in 2017, with projections of 82 million and 152 million in 2030 and 2045, respectively. There is a significant flaw in our understanding of AD pathology, as well as in the experimental models we use to depict human pathology and our therapeutic methods. In light of this, this Research Topic is created to highlight the critical significance of natural products in therapeutic development for human diseases. The therapeutic potential of several natural products, including crude extracts and purified compounds, has been demonstrated in numerous experimental models, with pharmacological efficacy comparable to that of known medicines. This includes effects via specific biological targets (enzymes, receptors, ion channels, and so on) or a variety of mechanisms extending from basic antioxidants and anti-inflammatory mechanisms to neuroprotection and neuroregeneration pathways. Insights into AD therapy using natural products in the form of original research articles or reviews in all areas of AD pathology, experimental designs, and therapeutic approaches are encouraged. The main goal of this collection is to put light on the current status of natural products in AD. As natural products including many polyphenols or other agents are given in combination with marketed available AD drugs to increase their efficacy. So, all those research areas that cover the current status of natural products in single or in combination with other agents to improve the efficacy of AD/dementia will be focused on. • Natural products targeting AD (In-vitro, in-vivo, and in-silico); • Drug discovery for AD by targeting pathways; • Combination therapy to improve the efficacy of Anti-AD agents; • Polytherapy vs single chemical entity; • Experimental models of dementia; • Novel bioassays for cognitive disorders.

Alzheimer’s disease is an increasingly common form of dementia and despite rising interest in discovery of novel treatments and investigation into aetiology, there are no currently approved treatments that directly tackle the causes of the condition. Due to its multifactorial pathogenesis, current treatments are directed against symptoms and even precise diagnosis remains difficult as the majority of cases are diagnosed symptomatically and usually confirmed only by autopsy. Alzheimer’s Disease: Recent Findings in Pathophysiology, Diagnostic and Therapeutic Modalities provides a comprehensive overview from aetiology and neurochemistry to diagnosis, evaluation and management of Alzheimer's disease, and latest therapeutic approaches. Intended to provide an introduction to all aspects of the disease and latest developments, this book is ideal for students, postgraduates and researchers in neurochemistry, neurological drug discovery and Alzheimer’s disease.

Focuses on the effects of natural products and their active components on brain function and neurodegenerative disease prevention. Phytochemicals such as alkaloids, terpenes, flavanoids, isoflavones, saponins etc are known to possess protective activity against many neurological diseases. The molecular mechanisms behind the curative effects rely mainly on the action of phytonutrients on distinct signaling pathways associated with protein folding and neuro-inflammation. The diverse array of bioactive nutrients present in these natural products plays a pivotal role in prevention and cure of various neurodegenerative diseases, disorders, or insults, such as Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, traumatic brain injury, and other neuronal dysfunctions. However, the use of these antioxidants in the management of neurodegenerative conditions has so far been not well understood. This is a comprehensive collection addressing the effects on the brain of natural products and edible items such as reservatrol, curcumin, gingerol, fruits, vegetables, nuts, and marine products.

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Neurodegenerative diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and amyotrophic lateral sclerosis, are the most common pathologies of the central nervous system currently without a cure. They share common molecular and cellular characteristics, including protein misfolding, mitochondrial dysfunction, glutamate toxicity, dysregulation of calcium homeostasis, oxidative stress, inflammation, and ageing, which contribute to neuronal death. Efforts to treat these diseases are often limited by their multifactorial etiology. Natural products, thanks to their multitarget activities, are considered promising alternatives for the treatment of neurodegeneration. This book deals with two different forms of natural products: extracts and isolated compounds. The study of the bioactivity of the extracts is extremely important as many studies have demonstrated the synergistic effect of the combination of different natural products. On the other hand, the investigation of the activity of specifically isolated natural products can be also important to understand their cellular and molecular mechanisms and to define the specific bioactive components in extracts or foods. This book can be considered an important contribution to knowledge of the neuroprotective effect of natural products and presents a great deal of information, related to both the benefits but also the limitations of their use in counteracting neurodegeneration.
