Beskrivelse
Inclusion Criteria:
- Must provide consent to participate after being fully informed about the study procedures and the information to be collected
- Males and females
- Ages 18-60 years old
- All races and ethnicities
- Probands: Must meet DSM-IV criteria for bipolar I disorder with or without lifetime history of psychosis; Healthy Controls: Must have no personal history of any psychotic or mood disorder, or a family history of psychotic or recurrent mood disorder among their first-degree relatives
- Must be judged to be capable of completing the study procedures by study investigators
- Must be able to read, speak, and understand English
Exclusion Criteria:
- An estimated IQ<70
- Major neurological or cognitive disorder (e.g., seizure disorder, traumatic brain injury, cerebrovascular disease, pervasive developmental disorder)
- Serious medical, neuro-ophthalmological, or neurological illness that could affect CNS functioning (e.g., decompensated cardiovascular disease, decompensated chronic obstructive pulmonary disease, late stages of diabetes, AIDS)
- DSM-IV diagnosis of alcohol or illicit substance abuse within 1 month, or alcohol or substance dependence within 3 months, or extensive history of past substance use
- Women who are pregnant (due to unknown risks related to MRI exposure)
- Presence of medical (e.g., artificial joints, brain aneurism clips, surgical pins, rods, wires, implants) or non-medical (e.g., metal piercing) irremovable metallic objects on/inside body (due to MRI-relevant risks)

Differences in those with Bipolar disorder with psychosis, without psychosis, and healthy controls in DNA and dermal biopsy sampling
Tidsramme: One day
|
The investigators will collect DNA from all proband and relative subjects and collaboratively sequence the genetic material to associate genes with specific biomarkers and composite Biotype definitions.
We will also collect plasma and cellular specimens to bank for analysis of additional molecular biomarkers unique to each Biotype.
