Compulsive hoarding
Obsessive-compulsive disorders are treated with various serotonergic antidepressants including the tricyclic antidepressant clomipramine and various SSRI medications. With existing drug therapy, OCD symptoms can be controlled, but not cured. Several of these compounds (including paroxetine, which has an FDA indication) have been tested successfully in conjunction with OCD hoarding.
Citalopram
It has been shown to be effective in 85% of patients with generalized anxiety disorder, including some who had failed with other SSRIs. It also appears to be as effective as fluvoxamine and paroxetine in obsessive–compulsive disorder. Some data suggest the effectiveness of intravenous infusion of citalopram in resistant OCD.
Citalopram is well tolerated and as effective as moclobemide in social anxiety disorder. There are studies suggesting that citalopram can be useful in reducing aggressive and impulsive behavior. It appears to be superior to placebo for behavioural disturbances associated with dementia. It has also been used successfully for hypersexuality in early Alzheimer’s disease.
