Participant has received chemotherapy treatment in the past 2 months. Participant has received electroconvulsive therapy (ECT). Participant has received radiation to the central nervous system. Participant experiences a physical condition or illness that interferes with normal cognitive functioning at work, school, Instrumental Activities of Daily Living (IADLs) etc. [if diabetes or hypothyroidism or hypertension and if controlled, participant can be accepted].
