Brief Summary
We hope to demonstrate that magnetic resonance spectroscopy can detect brain concentration levels of paroxetine (Paxil) or citalopram (Celexa) or escitalopram (Lexapro) in depressed patients.

Eligibility Criteria
Psychiatry clinic; local community.
You may qualify if:
- DSM diagnosis of Major Depressive Disorder
- Taking paroxetine \[(Paxil) or citalopram (Celexa) or escitalopram (Lexapro)\]for at least 6 weeks
- Between 21 - 75 years of age.
- Taking a stable dose of paroxetine \[(Paxil) or citalopram (Celexa) or escitalopram (Lexapro)\] for at least the 2 weeks prior to the imaging session
- Healthy controls:
- Between 21 - 75 years of age.
- Have a 21-item HAM-D score of less than or equal to 5.
- No current, or history of any Axis I disorder.
You may not qualify if:
- Contraindications for an MRI exam. These includes biomedical devices such as pacemakers, aneurysm clips, prostheses, and other metallic objects embedded in the body such as bullets, buckshot, shrapnel, and any metal fragments from working around metal.
- Current pregnancy or lactation.
- Patients with claustrophobia.
- History, or current Axis I or Axis II disorders
- Active unstable medical problems, as confirmed by screening procedures
- Diagnosed with any autoimmune disease, (e.g., rheumatoid arthritis, Lupus, MLS).
- Chronic use of steroids or opiates.
- Positive urine toxicology screen for illicit substances of abuse.
