Can dementia patients make their own decisions? Understanding legal capacity

3 min read

According to the Alzheimer's Association, legal capacity is the ability to make informed decisions and is evaluated based on the specific task at hand, not merely a dementia diagnosis. This means the answer to the question, “Can dementia patients make their own decisions?” is not a simple yes or no, as it depends on the stage of the disease, the complexity of the decision, and the patient's individual cognitive abilities at that moment.

Quick Summary

It is a misconception that a dementia diagnosis automatically removes a person's legal capacity to make decisions. Capacity is assessed on a case-by-case basis for specific decisions, considering a person's cognitive function and understanding. Supported decision-making can maximize autonomy, while legal documents such as a durable power of attorney should be prepared early to ensure wishes are respected as the disease progresses.

Key Points

  • Dementia is not an automatic loss of rights: A dementia diagnosis does not automatically mean a person loses the right to make decisions; legal capacity is evaluated for specific tasks.

  • Capacity is task-specific: An individual with dementia may be able to make daily living decisions but lack capacity for complex tasks like managing finances, depending on the stage of the disease.

  • Formal assessment is key: Professional assessment evaluates a person’s ability to understand, appreciate, reason, and express their choice for a specific decision.

  • Supported decision-making maximizes autonomy: Providing information in simplified ways and using visual aids can help an individual with dementia participate in decision-making for longer.

  • Advance legal planning is critical: Completing legal documents like a Durable Power of Attorney for finances and healthcare while capacity still exists is essential for respecting future wishes.

  • Guardianship is a last resort: If a person with dementia has not completed advance directives and loses capacity, family may need to pursue court-appointed guardianship, a more complex process.

  • Fluctuations in capacity are normal: A person’s ability to make decisions can change day-to-day. Assessments should account for this variability.

Legal Capacity vs. Diagnosis

It's a common misconception that a person automatically loses the right to make decisions upon receiving a dementia diagnosis. This is incorrect. An adult is assumed to have legal capacity unless proven otherwise. Capacity is not a global concept; it is task-specific. A person might have the capacity to make small daily decisions, like what to wear or eat, but lack the capacity for more complex tasks, such as managing large financial accounts. A clinical assessment is crucial for determining a person’s capacity for a particular decision.

The Role of Assessment in Decision-Making

Professional assessment determines a person's capacity to make a specific decision at a given time. Healthcare professionals evaluate several components of decision-making ability. These components include understanding the information, appreciating the situation, reasoning through options, and communicating a choice. This is not a one-time evaluation; capacity can fluctuate, so reassessments may be necessary.

Key components of a capacity assessment:

  • Understanding: The ability to comprehend and retain relevant information related to a decision. A person should be able to explain the situation in their own words. Forgetting the information soon after can indicate a lack of capacity.
  • Appreciation: The ability to appreciate the consequences of a decision in one's own situation. This involves recognizing that the information applies to them personally and their health or finances.
  • Reasoning: The ability to use the information and weigh the options to arrive at a rational choice. It is about the process of reasoning, not whether the outcome is a choice others would make.
  • Expressing a Choice: The ability to clearly and consistently communicate a decision.

Supporting Autonomy in Dementia Care

Even when capacity is diminished, supporting a person's independence is a key ethical priority. Supported decision-making models are designed to help individuals exercise self-determination for as long as possible. This involves providing information in a clear, simplified way, using visual aids, and creating a supportive environment. It’s about adapting the process to fit the person's remaining abilities.

Strategies for maximizing independence:

  • Simplifying Choices: Present fewer options at a time. For instance, ask, “Do you want to wear the blue sweater or the green one?” instead of asking them to choose from a whole closet.
  • Involving Trusted Supporters: A supporter helps gather information and communicate the person's wishes, but does not make the decision for them.
  • Timing Discussions: Choose a time of day when the person is most alert and rested for important conversations.

The Importance of Advance Directives

Since dementia is a progressive disease, it is crucial to plan for a future where a person may lack the capacity to make decisions. Legal documents, called advance directives, ensure that the person’s wishes for their future care and finances are respected. These documents must be completed while the person still has legal capacity.

Types of legal documents to consider:

  • Durable Power of Attorney for Finances: Appoints a trusted agent to manage financial affairs, such as paying bills and handling investments, when the person can no longer do so.
  • Healthcare Power of Attorney (or Proxy): Designates an agent to make medical decisions on the person's behalf if they lose capacity.
  • Living Will: Specifies a person’s end-of-life medical treatment preferences.

Comparison: Standard vs. Supported Decision-Making

Feature Standard (No Dementia) Supported (Early-Stage Dementia) Substitute (Late-Stage Dementia)
Initiator Individual Individual (with assistance) Appointed Agent or Court
Involvement Total independence Collaboration with a supporter Minimal to no involvement
Focus Independent action Respecting autonomy, providing help Best interests of the individual
Legal Authority Individual Individual (legal authority is preserved) Transferred to agent or guardian
Documents Optional Advance directives, POA Court-ordered guardianship/conservatorship
Risks Poor personal decisions Overreliance on supporter, delayed planning Substituted judgment may conflict with past wishes

Conclusion

While a dementia diagnosis signals progressive cognitive decline, it does not immediately strip a person of their ability to make decisions. The assessment of legal capacity is individualized and task-specific, allowing for continued autonomy in the early and middle stages of the disease. The process prioritizes supported decision-making to honor the person's self-determination for as long as possible. Crucially, early legal planning through durable power of attorney and advance directives is the best way to ensure a person's values and preferences continue to guide their care and finances when they eventually lose the capacity to do so themselves. This proactive approach helps protect their interests and reduces the burden on loved ones. For more detailed guidance, consulting an elder law attorney is highly recommended.

Frequently Asked Questions

No, a diagnosis of dementia does not automatically mean a person loses their legal capacity. Capacity is evaluated based on a person’s ability to make a specific decision at a specific time, not a blanket medical diagnosis.

Legal capacity is the ability to understand and appreciate the consequences of one's actions, and to make rational decisions. It is determined by assessing the person's ability to understand, reason, appreciate, and communicate a specific decision.

If a person loses legal capacity without a Durable Power of Attorney or other advance directives in place, family members may need to petition the court for guardianship or conservatorship, a more complex and costly legal process.

Families can use supported decision-making, which involves simplifying information, presenting fewer options at a time, and identifying the person's most alert times of day for important discussions. They can also use visual aids and involve a trusted supporter.

A Durable Power of Attorney for finances and a Healthcare Power of Attorney (or proxy) are critical documents to complete as early as possible after a diagnosis. A Living Will, which details end-of-life wishes, is also important.

Yes, as long as the person with dementia still has the legal capacity to understand the implications of their actions, they can formally revoke the existing Power of Attorney and create a new one.

Capacity is a functional assessment made by a clinician for a specific decision. Competency is a legal determination made by a judge in court and is a global assessment.
