Neurologists Detail Early Alzheimer's Signs Often Overlooked

Major memory loss is commonly associated with Alzheimer's disease, but neurologists emphasize that earlier, more subtle signs often go unrecognized or are attributed to other causes like stress or aging. These overlooked indicators can manifest in various aspects of an individual's life, according to experts.

Dr. Majid Fotuhi, a neurologist and adjunct professor at Johns Hopkins University, noted that people often expect Alzheimer's to present as forgetting names or misplacing items. However, he stated, "Often the earliest changes are more subtle." Similarly, Dr. Shaheen Lakhan, a neurologist, explained that these early changes can be gradual and easily dismissed as fatigue, stress, or the natural process of aging. Individuals may also unconsciously compensate for these changes, or family members might begin assisting with tasks without realizing the underlying cause. In some cases, a condition known as anosognosia can affect a person's awareness of their own difficulties, leading them to believe nothing has changed.

Changes in Judgment and Financial Management

One frequently missed sign involves alterations in judgment and money management. Neurologists point to a shift from careful financial habits to patterns of missed payments, duplicate billing, or uncharacteristic financial decisions. Individuals might also become more vulnerable to scams, make unusual purchases, or give away money in ways that are out of character.

Difficulties with Planning and Complex Tasks

Individuals who were once highly organized may begin to struggle with planning and keeping track of responsibilities. Dr. Fotuhi highlighted that tasks requiring coordination or numerical accuracy, such as managing investments or cooking elaborate meals, might become challenging. These difficulties can be mistaken for a loss of interest or simply the effects of aging.

Social Withdrawal and Mood Alterations

A shrinking social life can be an early indicator. People may stop organizing events, withdraw from conversations, or lose interest in activities they once enjoyed. Dr. Lakhan suggested this withdrawal can stem from difficulties finding words or keeping up with conversations. Furthermore, changes in mood and behavior, including apathy, new irritability, or anxiety, can appear before significant memory problems. Dr. Michael Stanley, a neurologist at Tufts Medical Center, noted that these mood changes are increasingly recognized as early precursors to cognitive decline, sometimes mistaken for depression or stress.

Challenges with Familiar Technology and Navigation

Overlooked clues can also appear in how individuals interact with everyday technology. Difficulty with familiar digital tasks, such as managing online banking or using a redesigned app, can signal cognitive changes. Persistent loss of previously comfortable skills, even with simple devices like a phone, may be concerning. Additionally, getting lost in familiar places, such as taking a wrong turn on a well-known route or feeling disoriented in a familiar store, can be indicative of cognitive decline, though sometimes attributed to vision problems.

Repetitive Questions and Smell Impairment

Repeating the same questions or stories without remembering having done so is another sign. While occasional forgetfulness is normal, a complete loss of the recent conversation is more telling. Some individuals may recall distant past events vividly while struggling to remember recent conversations or events. Research also suggests that a declining sense of smell can be an early clue, possibly due to immune cells in the brain attacking nerve fibers related to smell.

Concealing Lapses

Sometimes, the most telling sign is the effort made to hide or compensate for cognitive lapses. People may rely on notes, have a spouse answer questions, or dismiss forgetfulness as a long-standing trait. The brain's ability to compensate can mask changes for years, especially in individuals with higher education or demanding careers. Loved ones may also gradually take over tasks, a growing reliance that can serve as an important indicator for medical professionals.

When to Seek Evaluation

Experts advise against panic but urge individuals not to ignore potential signs. Consulting a primary care provider with specific examples and an approximate timeline is a recommended first step. Bringing a family member who knows the person well can be beneficial. A thorough evaluation should include cognitive assessments, blood tests, a review of medications, and screening for sleep problems and depression. Early evaluation can lead to timely diagnosis and intervention, potentially slowing disease progression and improving outcomes.
