Eligibility Criteria

Age18 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Patients with Major Depressive Disorder (MDD):
  • Age 18-55
  • Current diagnosis of MDD, as defined by DSM-IV criteria for recurrent MDD
  • Current depressive episode
  • Current IDS score in the moderately-to-severely depressed range
  • Right handed
  • Able to provide informed consent
  • Patients with Bipolar Disorder (BD):
  • Age 18-55
  • Current diagnosis of bipolar disorder, as defined by DSM-IV
  • Current depressive episode
  • Current IDS score in the moderately-to-severely depressed range
  • Right handed
  • Able to provide informed consent
  • Healthy Controls:
  • +3 more criteria

You may not qualify if:

  • Patients MDD \& BD:
  • Serious suicidal ideation or behavior (with a current plan or intent), or current delusions or hallucinations
  • Medical or neurological illnesses likely to affect physiology or anatomy
  • History of drug or alcohol abuse within 1 year or a lifetime history of alcohol or drug dependence (DSM IV criteria)
  • Current or past history of other axis I disorders that preceded the onset of MDD or BD
  • Current pregnancy (documented by pregnancy testing within 24 hours prior to pilot studies and 24 hours prior to scanning)
  • Current breast feeding
  • Vision and/or hearing problems severe enough to interfere with testing
  • Electrocardiographic evidence of ischemia, arrhythmia, conduction defect, or myocardial infarction
  • Current blood pressure of \>140 mm Hg or \< 90 mm Hg systolic, or \> 90 mm Hg diastolic (due to the potential cardiovascular effects of scopolamine and physostigmine)
  • Clinically significant cerebrovascular or cardiovascular disease, hypertension, congestive heart disease, angina pectoris, advanced arteriosclerosis, gross neurological impairment, hyperthyroidism, known hypersensitivity or idiosyncrasy to anticholinergic agents, glaucoma, renal or hepatic impairment
  • Clinical history of glaucoma or narrow angle glaucoma (due to the possibility of exacerbation of this condition by scopolamine)
  • Age of onset greater than 45 years (to reduce the biological heterogeneity encompassed by the MDD and BD criteria, since subjects with a late age-at onset for depression have a far greater likelihood of having MRI correlates of cerebrovascular disease than age-matched, healthy controls or age-matched, early-onset depressives)
  • Exposure within two weeks to medications likely to effect cerebral blood flow and metabolism or likely to interact with anti-cholinergic medications (e.g. narcotics or anti-cholinergic agents)- as verified by history and urine drug screen
  • HIV positive status
  • +12 more criteria
