Generalized anxiety disorder (GAD) is an anxiety disorder that
is characterized by excessive, uncontrollable and often
irrational worry about everyday things that is disproportionate
to the actual source of worry. This excessive worry often
interferes with daily functioning, as individuals suffering GAD
typically anticipate disaster, and are overly concerned about
everyday matters such as health issues, money, death, family
problems, friend problems, relationship problems or work
difficulties. Physical symptoms can include fatigue, fidgeting,
headaches, nausea, numbness in hands and feet, muscle tension,
muscle aches, difficulty swallowing, bouts of difficulty
breathing, difficulty concentrating, trembling, twitching,
irritability, agitation, sweating, restlessness, insomnia, hot
flashes, rashes, and an inability to fully control the anxiety.
These symptoms must be consistent and on-going, persisting at
least 6 months, for a formal diagnosis of GAD to be introduced.
