Obsessive Compulsive Disorder (OCD)
Transcript of Obsessive Compulsive Disorder (OCD)
Treatment: 1/3 of patients do not respond to therapy or SSRIs
Goals: develop treatments for OCD that work more effectively
Ways of Showing Symptoms
"Just right" OCD
Ways to Categorize OCD Symptoms
The scientific community is not completely aware of the causes of OCD
Association on chromosome 9 near PTRPD gene
Vulnerability to OCD can be inherited
OCD can run in families
Obsessive Compulsive Disorder (OCD)
Animals with OCD-like behaviors
Horses - stall vices
Dogs - tail chasing or ADL
Cats - pica or wool-sucking
Pigs - chain-chewing or bar-biting
most animals responded well to SSRIs: Prozac and Zoloft
Research into genetics
Patients must succumb to compulsions to alleviate stress
Sliding scale - not an on/off switch
Many side effects
usually coupled with psychotherapy for best resuls
Cognitive Behavior Therapy
Exposure and Response Prevention is most effective
Selective Serotonin Reuptake Inhibitors
Side effects include anticholinergenic effects
Fluoxetine (Prozac) - similar to clomipramine
Sample 1: patients with OCD
High levels of glutamate in CSF for sample 1 patients
Sample 2: control patients
often linked with other disorders
45 - 60% of TS suffer from OCD
about 2/3 of OCD patients have at least one other disorder
Many circuits in the brain
cortico-striatal-thalamus-cortical loop (CSTC)
starting to research into genetics using twins
Thanks for listening!!
