Yes. Someone with dementia may still make decisions about guardianship, and the diagnosis alone does not establish legal incapacity. Guardianship is a court arrangement that gives another person authority to make specified decisions for an adult.
The court examines the person's actual decision-making ability, including whether support could help. The U.S. Department of Justice emphasizes that people with significant cognitive challenges may still make decisions with trusted help or technology in its guardianship overview.

Who decides whether guardianship is necessary?
A court decides whether a person is legally incapacitated. A dementia diagnosis, medical opinion, or concerned relative cannot make that determination alone.
The judge considers medical, psychological, and other evidence about the person's decision-making ability. A clinical assessment may inform the case, but the court decides whether guardianship is justified and what authority it should include. The practical question is not simply, "Does this person have dementia?" It is, "Which decisions can this person understand and communicate, with or without appropriate support?".
Can the person participate in the court case?
The person named in a guardianship petition can take part in the proceeding. According to the U.S. Department of Justice, participation can include receiving notice, attending the hearing, having counsel, presenting evidence, and challenging witnesses during the guardianship process.
States typically require clear and convincing evidence before imposing guardianship. Testimony about the person's abilities, preferences, support network, and daily decision-making may therefore matter. Someone who can express preferences should raise them as early as possible. That includes views about whether a guardian is needed, whom the court should appoint, and which decisions the person wants to retain.
What outcomes can the court choose?
A guardianship petition does not guarantee a full guardianship or the petitioner's preferred guardian. The court may deny the request, select someone else, or grant fewer powers after reviewing testimony and written capacity assessments. A limited guardianship transfers only the powers named in the court order.
It preserves authority over decisions the adult remains able to make instead of removing all decision-making rights. For example, evidence may show that an adult needs help in one area but can still understand and express choices in others. The requested order should match the demonstrated need rather than assume that dementia eliminates every ability.
Does the person still have a voice after appointment?
Guardianship should not end the person's involvement in personal decisions. A guardian should ask the individual to make and express choices whenever possible. The guardian should also follow the person's known goals, values, and wishes when those preferences can be determined.
A best-interest decision should be used only when the person's goals and preferences cannot be identified. This approach matters even when the guardian holds final legal authority. Decision-making should remain centered on the person, not merely on what seems easiest for caregivers or institutions.
What should families consider before seeking guardianship?
Guardianship is intended as a last resort because it removes legal rights. The Department of Justice identifies supported decision-making, advance directives, powers of attorney, trusts, benefit payees, and narrowly tailored court orders as potentially less restrictive options.
Before or during a case, consider these practical steps: Rules, terminology, and procedural protections vary by state. A person with dementia who can communicate preferences should express them early in the local court process.
- Record the person's preferences about decision-making help and possible guardians.
- Identify decisions the person can make independently or with trusted support.
- Ask whether a less restrictive arrangement could address the specific concern.
- Review proposed guardianship powers individually instead of treating full authority as the default.
- Seek state-specific legal advice promptly.
