Neuroprotective Effects Of Phytochemicals In Brain Ageing

Phytochemicals are naturally occurring bioactive compounds found in edible fruits, plants, vegetables, and herbs. Unlike vitamins and minerals, phytochemicals are not needed for the maintenance of cell viability, but they play a vital role in protecting neural cells from inflammation and oxidative stress associated with normal aging and acute and chronic age-related brain diseases. Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the advances in our understanding of the potential neuroprotective benefits that these naturally occurring chemicals contain. Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the role that a number of plant-based chemical compounds play in a wide variety of neurological disorders.

Phytochemicals Signal Transduction and Neurological Disorders Phytochemicals are heterogeneous group of bioactive compounds produced by plants, which are extensively researched by scientists for their health-promoting potentials in human diseases. Unlike vitamins and minerals, phytochemicals are not required for sustaining cell viability, but they play an important role in protecting tissues and cells from the harmful effects of oxidative stress and inflammation. Examples of phytochemicals include catechins, resveratrol, ginkgo biloba, curcumin, and sulfur compounds found in garlic. Although, the precise molecular mechanisms associated with beneficial effects of phytochemicals still remain the subject of intense investigations, but it is becoming increasingly evident that phytochemicals mediate their effects by counteracting, reducing, and repairing the damage caused by oxidative stress and neuroinflammation. In addition, phytochemicals also stimulate the synthesis of adaptive enzymes and proteins through the stimulation of a transcription factor called Nrf2 and induction of phase II detoxifying enzymes. Consumption of phytochemicals induces neurohormetic response that results in the expression of adaptive stress-resistance genes that are responsible for encoding antioxidant enzymes, protein chaperones, and neurotrophic factor (BDNF). Based on the stimulation of signal transduction network and adaptive stress-resistance genes, it is proposed that the use of phytochemicals from childhood to old age along with regular exercise is an important strategy for maintaining normal aging and delaying onset of age-related neurological disorders (stroke, Alzheimer disease, and Parkinson disease). Phytochemicals Signal Transduction and Neurological Disorders presents readers with cutting edge and comprehensive information not only on bioavailability, and mechanism of action of phytochemicals in the brain, but also provides the molecular mechanism associated with beneficial effects of phytochemicals in neurotraumatic (stroke, spinal cord trauma, and traumatic brain injury) and neurodegenerative (Alzheimers disease, Parkinson disease, Huntington disease, and amyotrophic lateral sclerosis) diseases.

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.

Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders. * Contains the latest information on the subject of neurodegenerative disorders* Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems
