Does My Parent With Dementia Have Decision-Making Capacity? 5 Warning Signs Caregivers Should Not Ignore
How caregivers can recognize when a parent with dementia may no longer have decision-making capacity and what steps families can take to protect their loved one while maintaining dignity and independence.
One of the hardest moments in caregiving is realizing that a parent with dementia may no longer be able to make safe decisions. Many caregivers eventually ask an important question: does my parent with dementia still have decision-making capacity?
Dementia does not automatically mean someone has lost the ability to make decisions. Many people in the early stages of dementia can still participate in choices about their care, finances, and daily life.
However, dementia gradually affects judgment, reasoning, and memory. At some point, caregivers must ask whether their loved one can still understand the consequences of the decisions they are making.
Understanding dementia decision-making capacity can help families protect their loved one while preserving as much independence as possible.
Recognizing when decision-making ability is changing is also part of maintaining balance in caregiving, helping families prevent crises that overwhelm both the caregiver and the person receiving care.
What Is Decision-Making Capacity?
Decision-making capacity means a person can:
- Understand the information related to a decision
- Recognize how that decision affects them
- Reason through the available options
- Communicate a consistent choice
Doctors evaluate these four elements when determining whether someone has the ability to make medical or financial decisions.
Capacity is also decision-specific.
Someone may still be able to choose what they want for lunch but may no longer understand complex financial or medical decisions.
This is why physicians evaluate capacity for the specific decision being made, rather than assuming a diagnosis automatically removes a person's rights.
5 Warning Signs a Person With Dementia Can No Longer Make Safe Decisions
As dementia progresses, caregivers may begin to notice changes in judgment and reasoning.
1. They Cannot Explain Their Reasoning
Your parent may express a decision but cannot explain why.
For example, they may insist they want to go home but cannot explain where home is or why they want to go there.
A person with decision-making capacity should be able to describe the decision they are making and explain their reasoning.
2. They Do Not Understand Consequences
They cannot connect decisions with outcomes.
Examples include:
- Refusing important medications
- Insisting on driving despite getting lost
- Giving money to strangers or scammers
- Refusing necessary medical care
If someone cannot understand what could happen after their decision, their judgment may be impaired.
3. Their Decisions Change Frequently
A person may give completely different answers minutes apart.
Morning:
“Yes, I want the treatment.”
Afternoon:
“No, I never agreed to that.”
When choices change rapidly, it may indicate the person cannot retain information long enough to make a thoughtful decision.
4. They Become Easily Influenced
People with dementia are often vulnerable to manipulation.
Warning signs include:
- Agreeing with whoever last spoke to them
- Signing documents they do not understand
- Giving money away impulsively
- Being targeted by scams
Financial exploitation is unfortunately common among older adults with cognitive impairment.
5. They Cannot Remember Information Just Explained
If a doctor explains treatment options and the patient cannot repeat or recall that information minutes later, decision-making capacity may be compromised.
A person must be able to retain information long enough to consider their choices.
One of the most painful realizations in caregiving is understanding that protecting your parent may mean stepping in when they can no longer protect themselves.
How Doctors Determine Capacity
If caregivers are concerned about a loved one’s decision-making ability, a physician can perform a capacity evaluation.
This may include:
- Cognitive screening tests
- Questions assessing reasoning and understanding
- Evaluation of judgment and awareness
Doctors document whether the patient can:
- Understand the decision
- Appreciate the consequences
- Reason through options
- Communicate a consistent choice
If these abilities are impaired, the physician may document that the patient lacks decision-making capacity.
This documentation may be necessary to activate a Power of Attorney or protect the individual from unsafe decisions.
What Caregivers Should Say to the Doctor
Many caregivers struggle to explain their concerns to physicians.
Instead of saying:
“My mom has dementia. Can you take away her decision-making?”
A more effective approach is:
“I am concerned my mother may not understand the risks and consequences of her decisions. Could you evaluate whether she has decision-making capacity?”
Providing specific examples can also help doctors understand the situation.
Examples include:
- Missed medications
- Unpaid bills
- Getting lost
- Giving money to strangers
- Confusion about medical care
Real-life examples help physicians document concerns appropriately.
Protecting Your Parent Without Losing Yourself
Caregivers often feel guilt when they begin questioning a parent’s decision-making ability.
But stepping in when judgment becomes impaired is not about taking away independence.
It is about protecting your loved one from harm.
More importantly, addressing these issues early can prevent emergencies that create overwhelming stress for caregivers.
Caregivers who understand decision-making capacity early are better able to protect both their loved one and their own well-being.
This is an important step toward maintaining balance in caregiving, which is the foundation of the Caregiver Relief Balance Guide.
Caregiver Tip
If you are worried about your parent’s ability to make decisions, write down specific examples before speaking with the doctor.
Physicians need real-life observations to document impaired decision-making capacity. Helpful examples include:
- medication mistakes
- unpaid bills
- getting lost while driving
- repeated scams or financial mistakes
- confusion about medical instructions
Providing clear examples helps the doctor evaluate whether your parent can understand information, recognize consequences, reason through choices, and communicate a consistent decision.
Early evaluation can prevent medical, legal, and financial crises for both the caregiver and the person living with dementia.

Frequently Asked Questions About Dementia and Decision-Making
Does dementia automatically mean someone cannot make decisions?
No. A person with dementia may still have decision-making capacity, especially in early stages. Capacity is evaluated based on whether the person can understand information, appreciate consequences, reason through options, and communicate a consistent choice.
Who determines decision-making capacity?
A physician, neurologist, geriatric psychiatrist, or neuropsychologist can perform a capacity evaluation and document whether a person can make medical or financial decisions.
What happens if a parent no longer has decision-making capacity?
If capacity is impaired, a previously established Power of Attorney may become active. If no legal documents exist, families may need to pursue guardianship through the courts.
