Is willing to donate their brain for postmortem examination in case of death
The subject, or the subject and/or legally acceptable representative will be compliant and have a high probability of completing the study in the opinion of the investigator
Has been fully informed about the study, including provisions of the Health Insurance Portability and Accountability Act (HIPAA), as applicable, and informed consent or assent has been signed and dated (with time) by the subject and/or the subject's legally acceptable representative
