Generalized anxiety disorder (or GAD) is characterized by excessive, exaggerated anxiety and worry about everyday life events with no obvious reasons for worry. People with symptoms of generalized anxiety disorder tend to always expect disaster and can't stop worrying about health, money, family, work, or school.It may involve naturally occurring brain chemicals (neurotransmitters), such as serotonin, dopamine and norepinephrine. It's likely that the condition has several causes that may include genetics, your life experiences and stress.The exact cause of GAD is not fully known, but a number of factors including genetics, brain chemistry, and environmental stresses appear to contribute to its development.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
