Struggling at work and experiencing a sudden drop in productivity could be an early warning sign of early-onset dementia, surfacing more than a decade before a clinical diagnosis is made.
Early-onset dementia occurs when the condition develops in individuals under the age of 65, significantly impacting their professional and personal lives, often without any clear initial cause.
Because medical professionals do not typically screen younger demographics for cognitive decline, these patients often face prolonged wait times before receiving an official diagnosis.
However, a study conducted by researchers in Finland suggests that monitoring professional performance and changes in earnings could help identify the condition up to 15 years earlier than current diagnostic methods permit.
The research, which tracked nearly 800 early-onset dementia patients and 7,000 healthy individuals over a 12-year period, revealed a measurable decline in income among those who later developed the disease.
On average, individuals with early-onset dementia earned $13,800 less per year than their healthy peers starting a decade and a half before their formal diagnosis. Over the course of the study, this productivity drop resulted in an estimated loss of roughly $86,000 in total wages per patient.
Dr. Eino Solje, a neurologist who led the research, explained the connection between early symptoms and professional capability. He stated: "Early-onset dementia affects people during their most productive years and is associated with a decreased ability to work, increased unemployment and leaving jobs sooner than planned.
"These changes can reduce household income and contribute to broader economic impact. Our study found an association between reduced work productivity and early-onset dementia up to 15 years before diagnosis."
The study, published in the journal Neurology, broke down the data by specific types of dementia to see how quickly symptoms impacted earnings. For individuals dealing with early-onset Alzheimer's disease, lower earnings became noticeable six years before their official diagnosis.
Meanwhile, those affected by frontotemporal dementia showed a decrease in earnings starting 11 years prior to diagnosis. Though the data shows a clear pattern, researchers note that lower wages do not conclusively prove a person has dementia, as other external factors could also cause a drop in career performance.
Many people facing early-onset dementia report that their symptoms first manifest in the workplace. Common signs include difficulty remembering scheduled appointments, struggling to perform routine tasks that they have handled successfully for years, and finding it hard to concentrate or follow ordinary conversations.
As the condition progresses into later stages, individuals may experience severe mood swings, confusion regarding time and location, and uncharacteristic suspicion toward friends and family members.
An estimated 200,000 Americans currently live with early-onset dementia, and public health data indicates that this number is climbing. Health insurance claims for the condition surged by 200 percent between 2013 and 2017.
While the exact causes of early-onset dementia remain unclear, scientists note that genetics play a role, with about one in ten individuals carrying genes that elevate their risk.
Additional risk factors include a history of a brain injury from a stroke or heavy alcohol use. While there is no cure for the condition, medications are available that can help slow its progression.
