A guardian may be appointed for an individual whose ability to respond to people, events, and environments is impaired to such an extent that the individual lacks the capacity to meet the essential requirements for his health, care, safety, habilitation, or therapeutic needs without the assistance or protection of a guardian. A guardian for a minor may be appointed under this part if the minor meets the requirements of this section without regard to age and the minor's need for guardianship will likely continue into his adult years.
