Changes in financial behavior—like missed bills, impulsive spending, or difficulty managing money—can be early signs of cognitive decline. Learn what to look for, why early action matters, and how to protect financial wellbeing before problems escalate.

While Alzheimer’s disease is not a normal part of aging, someone’s risk of developing Alzheimer’s increases with age. As memory loss sets in, the risk of financial missteps increases. This not only puts personal assets at risk but also affects decision-making capacity. Additionally, Alzheimer’s care can be especially costly, as individuals may require extensive support for many years. Taking proactive steps to protect assets and secure financial stability can make a significant difference for both individuals and their caregivers as cognitive health changes. From missed bills to unusual purchases, subtle money mistakes may be one of the earliest warning signs of Alzheimer’s or dementia.
Financial decision-making abilities can begin to decline years before a formal diagnosis of Alzheimer’s or other dementias. A 2023 study found that in the eight years before a dementia diagnosis, U.S. household net worth drops to less than half that of households without dementia—$104,000 compared to $217,000—highlighting the broader financial toll on entire households (JAMA Neurology). A landmark study found that credit scores often drop and missed payments become more common, particularly for mortgages and credit cards (Federal Reserve Bank of New York). Small declines in attention, planning, and judgment can lead to major financial consequences. Individuals who eventually develop Alzheimer’s often begin missing bill payments or making uncharacteristic financial choices well before they or their loved ones recognize a memory issue (National Institute on Aging).
How can you tell if it’s time to take a closer look? Here are some warning signs to watch for:
- Trouble calculating a tip
- Confusion with bank statements
- Unopened or unpaid bills
- Missed payments
- Lots of new purchases on a bill
- Unusual or impulsive purchases
- Money missing from the person’s bank account (AARP)
Please be mindful that not everyone in the early stages of cognitive decline mismanages their finances, and not all financial missteps indicate a coming diagnosis. Some financial challenges can be due to the normal progression of age. While these issues can happen to anyone, repeated patterns and lack of awareness of financial consequences can signal early decline.
Brain changes associated with Alzheimer’s, such as shrinking of certain parts of the brain like the hippocampus, can lead to memory loss and forgetting to pay bills (NPR). Even before memory problems show up, it can get harder to plan, make choices, and judge risks — which can lead to money mistakes. Recognizing these early signs can prompt timely interventions, potentially safeguarding assets and minimizing financial fallout.

- Unfamiliar purchases

Preventive tools like fraud alerts and account monitoring are critical for early protection (AARP).
Start Early: Develop a financial plan before cognitive decline becomes a concern. If assisting a loved one, familiarize yourself with where accounts are held, what bills they pay, and their income sources.
Be Patient but Persistent: Those with Alzheimer’s may be reluctant to discuss finances or unaware of their challenges. Identify specific financial tasks where they struggle and offer targeted support while allowing them to maintain control over simpler tasks.
Simplify and Organize: Consolidate accounts to reduce the number of bills and statements. Anticipate potential costs, including healthcare expenses, and plan accordingly.
Automate Payments: Set up automatic bill payments and monitor accounts for unusual activity to prevent missed payments or unauthorized transactions.
Guard Against Fraud: Register on the Do Not Call list (donotcall.gov) and sign up for fraud alerts with financial institutions to monitor for suspicious activity.
Seek Professional Support: Consult an eldercare or estate planning attorney to establish legal protections, such as a durable financial power of attorney, to ensure a trusted individual can step in when needed (AARP).
