where
to go for help with generalised anxiety disorder?
There are
several different medications that can be used for the treatment
of generalized anxiety disorder. These include benzodiazepines,
buspirone, hydroxyzine, and antidepressants.
Benzodiazepines
are also known as "tranquilizers". Their major advantage
is that they work very quickly to reduce anxious feelings as
well as physical symptoms of anxiety. Their major disadvantage
is that when people discontinue them, there is often a "rebound"
anxiety, with return of GAD symptoms. Also, they are not effective
for the depressive symptoms that commonly co-occur in GAD. Furthermore,
there is an association between the use of benzodiazepines and
motor vehicle collisions due to subtle cognitive impairment.
Buspirone
(or Buspar) is the only medication in its particular class.
A major advantage of this agent is that it has relatively few
side effects; most people with GAD tolerate it very well. Disadvantages
of buspirone are that it takes 3-4 weeks before the agent begins
to work, and that it is not effective for the depressive symptoms
and other anxiety disorders that are often seen in people with
GAD.
Hydroxyzine
is a medication that has long been available. Like buspirone,
it too can be readily stopped at any point. Hydroxyzine is,
however, initially associated with some feelings of sedation.
This can be an advantage for some people (e.g. those with insomnia),
but it may be a disadvantage for others (e.g. those who need
to operate machinery). As in the case of benzodiazepines and
buspirone, it is not effective for the depressive symptoms that
often co-occur with GAD.
The term
"antidepressants" is a very poor one, as these medications
are in fact the first choice of medication for many different
anxiety disorders. Many of the antidepressants are effective
in GAD, and they are also often effective for the depressive
symptoms and other anxiety disorders seen together with GAD.
Their major disadvantage is that like buspirone, it may take
several weeks of daily medication before their positive effect
becomes apparent. Venlafaxine is one of the few antidepressants
that is in fact licensed for the treatment of GAD, although
other agents are likely to be registered in the future.
People with
GAD can be seen as viewing the world through a lens which colors
everything with negative predictions. Psychotherapy focuses
on attempting to change this lens (technically, this is the
"cognitive" part of "cognitive-behavioural therapy".
Steps in
the cognitive-behavioural therapy of GAD can include self-monitoring
and cognitive restructuring. Self-monitoring involves paying
closer attention to one's thoughts and feelings. In some ways
this is an exposure ("face the fear") technique, but
the technique is also useful in demonstrating to oneself the
connection between fearful thoughts about the future and feelings
of anxiety. Cognitive restructuring involves providing good
counter-arguments which dispell the logic of worry and fear
found in GAD. Common cognitive distortions in GAD include probability
overestimation, catastrophizing, and all or nothing thinking.
Overcoming such distortions may well require the help of a professional.
