Facts about Generalised Anxiety Disorder
About 5% of people will have generalised anxiety
disorder at some point during their lifetime. About
3-4% of the Australian population has generalised
anxiety disorder at any point in time - that
is, more than 500,000 Australians.
Although generalised anxiety disorder most often
starts in childhood or adolescence, it can also
begin in adulthood.
Generalised anxiety disorder affects slightly more
women than men. There seems to be a genetic component,
as some research suggests it runs in families.
Like depression, generalised anxiety disorder is
probably related to changes in brain chemicals called
neurotransmitters. Two neurotransmitters in particular,
noradrenaline and serotonin, are believed to play
a role in concentration, attention, anxiety, depression
and aggression. Depressive symptoms often occur
at the same time as anxiety, and many people with
generalised anxiety disorder will also suffer from
depression at some point.
