Causes of GAD - Generalized Anxiety
Disorder
Some research suggests that
Generalized Anxiety Disorder runs in families, or that it may be
caused by stressful situations. Other studies have focused on biological
explanations. Unfortunately, there is no clear-cut answer as to what
causes GAD.
Most modern research indicates that
generalized anxiety disorder may be caused by a chemical imbalance in
the brain. When we experience feelings such as happiness, stress, fear,
depression or anxiety, the brain releases chemicals known as
neurotransmitters. It is the release and re-absorption of these
neurotransmitters that affects how we feel. People who experience
anxiety and depression related disorders may have an imbalance of the
neurotransmitters serotonin, norepenephrine, GABA and dopamine. There
are medicines available that are designed to help 're-balance' the
release, reuptake and absorption of these key neurotransmitters.
It is important to note that in most
cases, one does not just experience a chemical imbalance disorder
overnight. A chemical imbalance is not the initial catalyst that leads
to generalized anxiety disorder. Conversely, there are triggers such as
excessive worry, stress and fearful situations that may lead you to
experience an improper release of these key neurotransmitters. If left
untreated more severe and debilitating effects may develop.
Although it is difficult to identify the
exact causes of generalized anxiety disorder, there are a number of
factors that seem to increase the risk of being diagnosed with GAD:
- Women are more at risk than men
- Incidence increases with age
- A previous marriage (ending in
separation, divorce or the death of the spouse)
- A personal history of depression or
drug or alcohol abuse
- A family history of depression, other
anxiety disorder, or drug or alcohol abuse
