Symptoms of Generalized Anxiety Disorder
Research shows GAD symptoms build gradually and more commonly affect younger and middle-aged adults. Per the ADAA, symptoms may include:
- Intense and persistent fears or worries
- Inability to deal with uncertainty about future events
- A constant sense of impending doom
- Intrusive thoughts
- Excessive and meticulous planning
- Fear of making the wrong decision
- Hyperventilation and excessive sweating
- Exhaustion and fatigue
- Difficulty concentrating
- Inability to sleep or relax
GAD is classified in the DSM-5 alongside OCD, panic disorder, PTSD, and social anxiety disorder. A licensed professional is needed to accurately distinguish between them.
Causes of Generalized Anxiety Disorder
The exact cause of GAD is unknown; a combination of factors contributes.
- Genetics: Evidence suggests a family history of GAD raises individual risk, indicating a partial genetic component.
- Neuroticism: Research links anxiety disorders to neuroticism — a tendency toward self-doubt and negativity.
- Trauma and chronic illness: Traumatic experiences and chronic illness are contributing risk factors.
- Substance misuse: Misusing addictive substances increases risk.
- Brain chemistry: A study in Psychiatric Clinics of North America suggests anxiety symptoms may stem from imbalance in emotional centers of the brain. MRI scans show serotonin and other chemical imbalances in people with anxiety disorders.
Risk factors can be moderated by early intervention and a strong support system.
