What to do After a Dementia Diagnosis

A dementia diagnosis can feel like the ground has shifted beneath your family—but it does not always mean it is too late to plan.

When a loved one receives a dementia diagnosis, families often focus first on medical care. That is understandable. Doctors, medications, safety, driving, and daily routines may suddenly become urgent concerns.

But dementia is not only a medical issue. It can also affect legal and financial decision-making.

The good news is that a diagnosis does not automatically mean your loved one has lost the ability to sign legal documents. Many people in the early stages of dementia can still make decisions, understand their wishes, and legally complete or update important planning.

The key is not to wait.

The Medical Clock and the Legal Clock Are Different

Families often assume that once someone is diagnosed with dementia, they can no longer sign anything. That is not always true.

A doctor may diagnose cognitive decline, but legal capacity is usually evaluated at the time documents are signed. The question is whether the person understands what they are doing, what they own, who their family members are, and what the document is intended to accomplish.

Someone may have dementia and still have the legal capacity to sign certain documents.

That is why a diagnosis should be treated as a signal to act, not a sign that all planning options are gone.
