But do the brain wave states you train your brain to have any affect
on anxiety for more than a few minutes?  I don't believe you could
maintain a particular wave pattern for very long in normal day to
day activity no matter how long you practised.

I've yet to hear of case where hypnosis affected a long term
reduction in anxiety. Do a search of past ASAP posts at Google, and
I doubt you will find one person having had a positive result from
it.

There have been a number of international consensus panels reviewing
the effectiveness of various treatments for anxiety disorders. All
have found that only medication and CBT are effective. Some are
available on the web, do a search using 'consensus'  'panel'
'anxiety'  'ocd'  'panic' 'phobias'

Which rather proves what I said. If you look at the few long term
studies into the effectiveness of CBT, the results after 12 months
are about the same as in control groups that had no treatment. CBT
works well initially, but humans, being human tend to stop working
at it after a while and anxiety (and depression) returns.

My point on this is, that neuro scientists don't necessarily know
much about psych disorders. These disorders are rarely due to a
neurological disorders as such, though small differences in
physiology have been found in patients with some anx disorders.

The only likely adverse effect of flashing lights is the triggering
of seizure in those that are susceptible - usually those with a
seizure history.

It is unlikely that it can produce  psychosis. Psychosis, and
psychological states generally, are not the result of faulty brain
wave patterns.
