Norepinephrine is a chemical neurotransmitter. Drugs that directly manipulate central nervous system (CNS) norepinephrine are being developed targeting noradrenergic neurons to deliver therapeutic effects. Noradrenergic drugs have been proven effective for depression and ADHD, and new disease indications are being identified. Recent discoveries about norepinephrine's contribution to health, disease, and therapy make this synthesis of evidence, practice and research very timely. A team of experts provides the reader with a thorough understanding of the anatomy, physiology, molecular biology, pharmacology, and therapeutics of norepinephrine in the brain, including an extensive review of the role of norepinephrine in brain diseases. The book is divided into four sections: the basic biology of norepinephrine; the role that norepinephrine plays in behavior; evidence of norepinephrine's role in CNS diseases, and the pharmacology and therapeutics of noradrenergic drugs in the treatment of psychiatric and neurological disorders.
