    Beschreibung / Inhaltsverzeichnis: Frontiers in Clinical Drug Research - CNS and Neurological Disorders is a book series that brings updated reviews to readers interested in advances in the development of pharmaceutical agents for the treatment of central nervous system (CNS) and other nerve disorders. The scope of the book series covers a range of topics including the medicinal chemistry, pharmacology, molecular biology and biochemistry of contemporary molecular targets involved in neurological and CNS disorders. Reviews presented in the series are mainly focused on clinical and therapeutic aspects of novel drugs intended for these targets. Frontiers in Clinical Drug Research - CNS and Neurological Disorders is a valuable resource for pharmaceutical scientists and postgraduate students seeking updated and critical information for developing clinical trials and devising research plans in the field of neurology. Volume 10 of the series continues to present novel information about new and interesting approaches to treat common neurological disorders, with a focus on neurodegeneration and pain medicine. The volume presents 7 detailed reviews in total. - Neurodegenerative disease: prevention and treatment through plant extracts therapy- Emerging novel approaches and recent advances in Parkinson's disease treatment and diagnosis- Neurotrophic factors to combat neurodegeneration- Neural bases of executive function in ADHD children as assessed using FNIRS- Modulation of mesenchymal stem cells, glial cells and the immune system by oligodeoxynucleotides as a novel multi-target therapeutic approach against chronic pain- Chronic pain: focus on anticonvulsants- A review of the impact of testosterone on brain and aging-related decline in brain behavioural function.
