• Inclusion - Bipolar Disorder Subjects:
• DSM-IV-TR12 criteria for bipolar disorder, type I, manic or mixed episode, diagnosed by the Washington University in St. Louis Kiddie Schedule for Affective Disorders and Schizophrenia (WASH-U-KSADS)166,101,102-103,104-105,108
• Baseline YMRS112-114 score \> 20;
• Ages 12-17 years 11 months old;
• Fluent in English;
• Provision of written informed consent by a legal guardian and written assent by the subject;
• Tanner scale stages III-V167, in order to include only post-pubescent subjects and minimize brain changes associated with the onset of puberty;168-169
• Less than 2 years from onset of bipolar disorder, defined by age at onset of first DSM-IV-TR affective episode (mania, hypomania, depression or mixed), to establish that our sample is early in their illness course;
• No prior psychiatric hospitalizations, \<3 months of lifetime psychotropic medication exposure (with the exception of psychostimulants, since excluding patients with psychostimulant exposure would significantly limit the generalizability of our findings), and no active psychotropic medication during the week (72 hours for psychostimulants and benzodiazepines) prior to the index assessment (no treatment with fluoxetine during the prior month). Please note that patients will NOT be taken off medications for the purpose of this study; instead, this criterion is to exclude subjects receiving treatment at the time of index assessment;
• Does not have a history of intolerance or non-response to lithium or quetiapine;
• Manic or depressive symptoms do not result entirely from acute medical illness or acute intoxication or withdrawal from drugs or alcohol as determined by medical evaluation and rapid symptom resolution;
• No lifetime DSM-IV-TR diagnosis of post-traumatic stress disorder (PTSD), since PTSD has been associated with abnormalities in prefrontal NAA and function170-171,172. Furthermore, bipolar patients with co-occurring PTSD are less likely to respond to lithium monotherapy, and often need a serotonin specific reuptake inhibitor (SSRI) as adjunctive treatment to a mood stabilizer.173,174 ;
• If female and of child bearing potential, agrees to use one of the following method of birth control: complete abstinence from sexual intercourse, barrier (diaphragm or condom), or oral/injectable contraceptive.
• Inclusion - Healthy Controls:
• Ages of 12-17 years and 11 month;
• No history of any DSM-IV-TR Axis I disorder (nicotine dependence is permitted);
• No first- or second-degree relatives with an affective or psychotic disorder;
• No medications with central nervous system effects within 5 half-lives;
• Fluent in English;
• Tanner stage III-V;
• Provision of informed consent and assent.
• Exclusion - Bipolar Subjects \& Healthy Controls:
• Contraindication to an MRI scan (e.g., braces or claustrophobia);
• An unstable medical or neurological illness that could influence fMRI or MRS results;
• IQ \< 70, as determined by The Wechsler Abbreviated Scale of Intelligence (WASI) ;
• A positive pregnancy test;
• A history of major medical or neurological illness or a significant episode (\> 10 minutes) of loss of consciousness;
• Any lifetime DSM-IV-TR substance use disorder (nicotine dependence is permitted);
• A lifetime DSM-IV-TR diagnosis of any pervasive developmental disorder;
• The patient lives \>100 miles from the University of Cincinnati or is not able to attend follow-up visits.
