As editors of this book our aim was to collect new data from experienced authors in order to further advance the knowledge on the protective effects of polyphenols' intake, e.g., when included in the human diet, to modulate cellular functions and pathways associated with neurodegenerative diseases.Fruits and vegetables are the richest source of polyphenols in the regular human diet. Most of these molecules possess high antioxidant capacity, as well as several other important activities that can affect human health, among which anti-inflammatory properties and the potential ability to modulate different cell-signalling pathways seem to be the most important. Neurodegenerative diseases are among the main causes of death worldwide and, in most of them like Alzheimer's or Parkinson's, neurodegeneration occurs long before the onset of first symptoms, where a large population of brain neurons are already lost. Besides neurons, glial cells like astrocytes and microglia, are involved in oxidative and neuroinflammatory pathological pathways, making them interesting targets for neuroprotective strategies. Polyphenols are promising candidates for those strategies, either as prophylactic substances or as therapeutic molecules.In this book, several research papers and two reviews explore the chemical properties of naturally occurring polyphenols and some new possibilities for the therapeutical and/or prophylactic roles of these molecules on neurodegeneration and neurodegenerative diseases.

Natural and chemical compounds, often used as both dietary supplements and alternative medicines, are characterized by specific chemical properties, allowing their passage across the blood brain barrier with consequent specific effects on neurotransmission. In particular, several natural compounds have shown beneficial properties in the treatment of neuropsychiatric disorders, especially cognitive impairment and mood disorders, contributing to the maintenance of the physiological brain functioning by interacting with different receptors, transcription factors and signal transduction pathways. Neuroinflammation and oxidative stress have also been proposed as crucial contributors to brain dysfunction development, thus recent investigations have focused on novel therapeutic approaches based on the use of phytoderivates with neuroprotective properties. Thus, this Special Issue includes a collection of 11 papers, describing key findings for the identification of molecular mechanisms required for the development of potential and promising natural therapeutics for the treatment of psychiatric and neurodegenerative disorders.

In vivo brain neuroimaging with cutting-edge technologies has achieved great success with high spatial and temporal resolutions. Several distinct medical imaging perspectives such as disease neurobiology, multimodal imaging techniques and applications, large-size clinical trials of neuro-oncology, and bioinformatics with illustrative examples and comprehensive summaries could expand our knowledge ...
