ICJI 908 UNSOUNDNESS OF MIND—DEFINED
INSTRUCTION NO. A person is of unsound mind if that person is incapable of normally managing affairs in a reasonable manner. Unsoundness of mind exists when the intellectual powers are fundamentally lacking, or where incapable of understanding and acting with discretion in the ordinary affairs of life. The term 'unsoundness of mind' thus includes a range of mental impairment.
