Book Description
This book reviews the scientific literature and the authors’ own research linking aluminum neurotoxicity with cognitive impairment and Alzheimer’s disease (AD). It focuses on aluminum levels in the brain, region-specific and subcellular distribution, its relation to neurofibrillary tangles and amyloid beta—the pathological features of AD, and the possible mechanism of aluminum inducing these pathological features. Further, the book stresses the importance of aluminum’s complex speciation chemistry in relation to biology, and details aluminum’s mechanism in oxidative stress and cell death, especially in connection with apoptosis and necroptosis. The electrophysiological variation and synaptic plasticity induced by aluminum are covered, while the metal’s debatable role in AD and the cross-talk between aluminum and genetic susceptibility are also discussed, and more recently the relationship between aluminum-induced epigenetic modification on DNA and non-coding RNAs and neuron death and synaptic impairment. The second edition updates eight chapters according to the most recent researches. Content about aluminum-induced AD-like pathological features, neurotoxic effects of aluminum and aluminum alloy nanoparticles(TBD) and alumina nanoparticles induced neurotoxic and neurodevelopmental toxic effects is also added. In closing, this book provides readers with a systematic summary of aluminum neurotoxicity.

Book Description
Aluminum is the third most abundant element in the Earth's crust. In many of the previous experimental, epidemiological, pathohistological, biochemical and other research studies, aluminum, accumulated from the environment has been recognized as a very harmful substance to the human body. Aluminum intake usually happens unintentionally due to the fact that people know little about its prevalence in water, factory-processed foods, medicines, cosmetics, etc. When accumulated in human organs, it can cause severe damage, and even lead to chronic neurodegenerative diseases. Both oxidative and nitrosative stress can be the leading cause or contribute to its toxic effects in humans and animals. All of this is supported by the fact that mitochondrial dysfunction is the earliest stage of aluminum neurotoxicity. When oxidative damage occurs under the effects of free radicals, together with the decreased antioxidant protection due to the decreased production of the chemical energy molecule (adenosine triphosphate) as well as reducing equivalents (both in and out of mitochondria) then the conditions for the occurrence of a vicious circle in aluminum neurotoxicity are created. Aluminum also significantly interferes with the main steps of the synaptic neurotransmission, which may lead to the progression of neuropathies. The glutamate-glutamine pathway and numerous neurotransmitter transporters are affected as well. Oxidative stress and the disruption of neurotransmission do not only exist when adult individuals are exposed to this neurotoxin, but also in individuals prenatally exposed to it as well, and these are expressed after birth. Numerous research studies, both in animals and humans, ex vivo and in vitro, quite clearly showed that aluminum can be associated with chronic neurodegenerative diseases. Additionally, there is a positive correlation between the exposure to aluminum and the pathophysiology of Alzheimer's, Parkinson's, Huntington's disease, amyotrophic lateral sclerosis, and so on. One of the possible mechanisms for the generation/development of these diseases could be the disturbed homeostasis of essential metals and the appearance of unfolded or misfolded proteins that are mostly specific for a particular disease. In those research studies, the influence of aluminum on the generation of beta-amyloid, alpha synuclein, etc. was satisfactorily examined. It is very difficult, however, to suppress aluminum neurotoxicity, as well as development and progression of the diseases caused by or associated with aluminum. This is the result of some complex mechanisms through which aluminum causes its deleterious effects, and which are also responsible for the existence of multiple targets for aluminum. It is, therefore, necessary to know how these mechanisms induce the damage, in order to be able to prevent or treat the damage once it occurs. A large number of substances, including active components in traditional medicine, medical drugs and substances which are used only experimentally, have been examined so far. The results of studies conducted so far are inconclusive and they require further research. According to all the aforementioned findings, it may be concluded that well-planned, prospective and randomized clinical trials are necessary in order to use any of these substances in humans.

Book Description
Aluminium is a chemical element present in earth’s crust and it is a known environmental toxin which has been found to be associated with various neurological disorders. Aluminium has been found to be a very strong risk factor for the development of Alzheimer’s disease. Biochemical Mechanisms of Aluminium Induced Neurological Disorders explains the association of aluminium with neurological disorders. The book introduces the reader to sources of aluminium exposure, followed by an explanation of pharmacokinetics of aluminium and the different biochemical pathways that cause neurological effects. Chapters cover the typical mechanisms associated with aluminium neurotoxicity such as synaptic impairment as well as recent topics of interest such as the role of aluminum in impairing blood-brain barrier functions. Separate chapters which cover clinical evidence of aluminium toxicity and its management are also included in the book. Biochemical Mechanisms of Aluminium Induced Neurological Disorders is a concise, yet informative reference on the subject of aluminium neurotoxicity for all readers, whether they are students of biochemistry, pharmacology and toxicology, clinical neurologists, environmentalists interested in metal pollution or general readers who want to learn about the toxic effects of aluminium in humans.

Book Description
Trace minerals and metals such as zinc, copper, and magnesium are accepted as a "natural" part of the human system. Interactions of some elements and/or disturbances in trace-metal or mineral homeostasis can, however, be toxic to the central nervous system (CNS). Mineral and Metal Neurotoxicology describes a wide range of basic and clinical issues
