1.
2.

severe and need to prevent further loss.

SSRIs seem to be the treatment of choice for most
pervasive and impairing anxiety disorders in youth.
TCAs are a second-line treatment due to side effects
and less overall efficacy.
Benzodiazepines are less commonly used due to risk of
dependency, better alternatives, disinhibition.
Atypical antipsychotics may have a role.
