Generalized anxiety disorder in adults
GAD, or generalized anxiety disorder, is a feeling of nervousness, like fear or worry, that can either be severe or mild. Everyone will develop anxiety at some stage; for example, it can be an exam, medical test, or job interview. During these times, being anxious is entirely normal, but few people may find it hard to control their fears or worries. Their feeling of anxiety can be more constant and have an impact on their daily lives, and it can also be a sign of several conditions like:
- Panic disorder
- Phobias
- PTSD (Post-traumatic stress disorder)
- Social anxiety disorder

Generalized anxiety disorder causes
The exact reasons for developing GAD are not fully understood, but it is more likely to be a combination of multiple factors that may include:
- Overactivity in brain emotion and behavior areas

- Inherited genes from parents. You are five times more likely to develop GAD in you have a close relative with the same condition
- Having a history of any traumatic or stressful events such as child abuse, domestic violence, or bullying
- Having severe, painful long-term conditions
- Having a past of alcohol abuse or drugs
But multiple people tend to develop GAD for no apparent reason.
