Investing and the Aging Brain: ‘What Do I Do When I Get Stupid?’

Financial decision-making ability peaks in middle age. Plan accordingly.

In a recent encounter with a former student, Lewis Mandell, a professor of finance and managerial economics at the University of Washington, was asked: “What do you know about annuities? I’m thinking about buying an annuity.”

“I was really embarrassed,” Mandell said. I told him “you attended an entire semester of my investments course and know annuities are often laden with fees and that buying one at the bottom of an interest rate cycle might be a risk. You’re a smart guy, are you sure you want to buy an annuity?”

“Yes,” the physician replied, “I took your course and realize those things. My concern is—what do I do when I get stupid?”

Scientists no longer view cognitive impairment in old age as simply a misfortune that strikes some who suffer from a random event such as Alzheimer’s or a stroke. There is increasing evidence that cognitive decline in old age is natural and inevitable. In fact, the rate of decline in old age does not appear to be slowed by education or intelligence, and is unaffected by solving crossword puzzles or reading Russian novels. Our brains, like the rest of our body, lose their ability to respond quickly and precisely over time.

In a series of academic studies on cognitive aging, Timothy Salthouse, director of the University of Virginia Cognitive Aging Laboratory, tests mental functioning by asking respondents to perform tasks such as naming a synonym to a random word, detecting patterns or recalling a list of words. Coming up with a synonym is an example of a task that requires crystallized intelligence, or the ability to process a stimulus (the word) and relate it to an item in memory (the synonym). Tasks requiring processing and some knowledge or experience tend to peak in the late 50s. The other tasks require speed, reasoning and memory. These skills test fluid intelligence, which tends to peak in the 20s. Einstein’s so-called magic year occurred when he was 26 years old.

Like the synonym task, financial decision-making requires both the ability to respond to a stimulus and to place it into context through knowledge. Recent academic studies find that respondents make their best financial decisions when they are in their mid 50s. Sumit Agarwal, a senior financial economist at the Federal Reserve, and his co-authors found that effective financial behavior, such as limiting credit fees and interest rates paid on home equity loans, peaked in the late 40s and early 50s. Studies of investments confirm this financial performance peak in late middle age. George Korniotis and Alok Kumar, professors at the University of Miami, find that risk-adjusted investment returns decline with advanced age. Investors over 70 underperform by about 2% annually compared to younger investors.

A recent study using data from the Texas Tech Financial Literacy Assessment project shows that the decline in our ability to make basic financial decisions mirrors the results on investment and credit performance. The study found that the ability to understand financial concepts and apply them appropriately peaks in the early 50s and declines by about 2% per year after age 60. The rate of decline is no different at older ages, and a score at age 90 is about half what it was at age 65. Like other research on cognitive aging, this study found no increase in the dispersion of scores later in life, indicating a gradual decline among all older respondents rather than a few seriously impaired subjects dragging down the average. 

While financial abilities decline with advanced age, confidence in one’s ability to make financial decisions does not. In fact, respondents in their 80s believe their financial knowledge is slightly higher than do respondents in their 60s. This inability to assess a decline in skills with age is not limited to financial decisions. Results from a new study conducted by researchers at the University of Alabama find that subjects over age 65 do not perceive their decline in driving ability despite clear evidence of reduced visual acuity and reaction times. In fact, older drivers who had multiple crashes were no more likely to rate their driving ability as worse than average.

This lack of awareness is a problem for a financial advisor managing the assets of a client who begins making questionable financial decisions. Eric Park, a financial advisor in Washington, Mo., describes the position of serving as a fiduciary to a client making questionable choices as a challenge. “Because of restrictive privacy laws, we find ourselves dancing around those issues. At the end of the day, every ethical planner has to ask himself how much legal exposure am I willing to withstand to protect [my]client. A planner who breaches privacy laws could very well find himself losing licenses, getting fined and even being subjected to monetary penalties or jail time.”

Planning for Decline

Notes Mitzi Lauderdale, an attorney and financial planning professor in Lubbock, Texas: “Planning for incapacity or partial capacity is crucial. Documents such as a durable power of attorney, medical power of attorney, will, trusts and advanced medical directives should be implemented well before any capacity concerns arise.”

Park believes that a power of attorney may not be necessary if a client has someone they can trust when an advisor begins to recognize cognitive decline. An HIPAA release can be combined with a medical power of attorney giving the advisor a right to disclose medical information. “Power of attorney gives people the power to do things. We don’t even need that,” he says. A waiver gives an advisor the ability to contact “a family member or attorney to make them aware that the client is about to give half their money to a charity you’ve never heard of. They may then be able to secure a legal remedy by getting the court to appoint them a guardian to protect the client.”

According to Lauderdale, “client engagement letters can be particularly useful to facilitate and document further communication on how and when an advisor will respond when the client experiences diminished capacity.” An attorney-in-fact, through a durable power of attorney, can give a guardian the ability to make decisions on the client’s behalf. The attorney-in-fact should be given only to “a trusted family member or friend and should not be the RIA or broker/dealer,” states Lauderdale. She recommends that the advisor encourage a client to sign documentation giving the advisor permission to discuss financial affairs with the attorney-in-fact. “The key is to have informed consent during times of capacity so that documentation is in place. There may be some pushback from clients as they fear losing independence and giving someone else permission to go against their wishes.”

In Park’s view, documentation that spells out a plan to deal with cognitive impairment is an essential part of the planning relationship. “We need to have somebody we can contact,” he contends. “These contacts may not have the same privacy requirements. They can go to court and get an order to freeze an account or get a mental competency hearing in order to eliminate a tremendous amount of potential liability. We almost don’t have an account where there isn’t somebody else we can contact.”

Advisors can perform a valuable role in recognizing reduced cognitive ability and preventing financial calamity if they have the tools to provide assistance. Without the appropriate legal authority, they are often powerless to help. Lauderdale notes that “when one’s capacity is diminished beyond their ability to fully understand the facts related to their person and to make rational decisions with the facts as they understand them, they no longer have legal capacity to make decisions for themselves. This is challenging for planners because they are still your client and you are still supposed to follow their lead. While planning decisions still may be in the best interest of the client, a client may no longer have capacity to direct the transactions.”

In order to avoid possible lawsuits from family members disappointed that a parent receiving professional financial management has squandered their inheritance or made them responsible for covering the expenses of an aging parent, a planner needs to be particularly cautious when recommendations are not being followed. Lauderdale notes that “if a client is making decisions that are not in their best interest and especially if they are not suitable, you must document decisions that are against your recommendations to protect yourself. When capacity is clearly lacking, an attorney-in-fact, via a durable power of attorney, will stand in the shoes of the client to make decisions on their behalf. The POA must have been executed prior to incapacity.”

Diminished mental capacity can also lead to family conflicts when a client becomes more vulnerable to financial requests from family members. Harold Evensky, a financial planner in Coral Gables, Fla., finds that older clients will often bring a trusted child with them and he asks for permission to speak with either or both of them in the future. Evensky says that it is “relatively rare that we would talk to the child.” Being given responsibility for addressing concerns about an aging parent’s cognitive decline is “quite a burden on them, but that’s part of the reality we deal with. There may be a responsible child and a spendthrift child that’s had drug or mental [problems], and then we rely on the responsible child to help manage the issue.”

Childless retirees, or those who have not identified a trusted younger guardian to help maintain their financial welfare in old age, can plan for diminished cognitive capacity early in retirement by making choices that reduce decision-making burdens later in life.

Professor Mandell believes that all of us need to acknowledge that cognitive decline is an important part of the retirement planning process. His encounter with the former student who asked about annuities underscored that point. By considering investment options that provide income without significant investment management input, and that lock up wealth to prevent losses from financial mistakes, the questioner was modeling a more informed approach that reduces the negative impact of cognitive aging.

“Here was a very smart guy who takes a course on investments and is smart enough to realize his cognitive ability is going to decline. He wanted to make sure that he was not going to screw up managing the assets that he and his wife will depend on for the rest of their lives.”
