10 medical conditions show connection to Alzheimer’s years before diagnosis

New blood test may predict Alzheimer’s disease risk Dr. Jeremy Koppel explains the breakthrough blood test for Alzheimer’s disease, detailing how it identifies abnormal protein accumulation. He clarifies the test’s current role in diagnosing symptomatic individuals. NEWYou can now listen to Fox News articles!
Certain medical conditions may signal early-onset Alzheimer’s disease several years before diagnosis, a new Finnish study suggests.Researchers found that depression, vertigo, headaches and other conditions were more common during the five years preceding diagnosis, potentially offering clues for earlier detection.The researchers analyzed medical records from 407 people with early-onset Alzheimer’s disease and 4,035 people of similar age and sex without the diagnosis, focusing on the 15 years prior to diagnosis.SUBTLE CHANGE IN HOW YOU SPEAK COULD BE EARLY SIGN OF DEMENTIA RISK, NEW RESEARCH SUGGESTSThe average age at diagnosis was 60. Early-onset disease is diagnosed in people under 65.The findings were published in the journal Alzheimer’s & Dementia. Certain medical conditions may signal early-onset Alzheimer’s disease several years before diagnosis, a new Finnish study suggests.

(iStock)Differences in medical conditions were most pronounced in the five years before an early-onset Alzheimer’s diagnosis, the study showed.3 THINGS TO AVOID IN MIDDLE AGE COULD MEAN 13 MORE YEARS WITHOUT DEMENTIA, STUDY FINDSThe researchers also found that healthcare visits increased substantially among early-onset Alzheimer’s patients immediately before and during the time of diagnosis, which may indicate emerging symptoms.CLICK HERE FOR MORE HEALTH STORIES”It is well-known that the neuropathological changes associated with Alzheimer’s disease begin at least 15 to 20 years before clinical cognitive symptoms appear,” Suvi-Johanna Krüger, M.D., Ph.D., study co-author and clinical lecturer at University of Oulu, said in a press release.”Most previous studies have focused on late-onset Alzheimer’s disease, and considerably less is known about early-onset Alzheimer’s disease.” The researchers analyzed medical records from 407 people with early-onset Alzheimer’s disease and 4,035 people of similar age and sex without the diagnosis, focusing on the 15 years prior to diagnosis. (AP Photo/Evan Vucci, File)Study limitationsBecause the study was observational, it only establishes associations and cannot demonstrate that these conditions can reliably predict Alzheimer’s disease.”Our study cannot determine whether these conditions cause early-onset Alzheimer’s disease or whether they are consequences of the underlying disease process,” Krüger noted.CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER”Some conditions may represent risk factors, while others may reflect early symptoms or changes occurring during the prodromal phase of the disease.”It is also possible that genetics, lifestyle and socioeconomic factors played a role in the patients’ outcomes.”Early diagnosis is important because more treatment and support options are available in the early stages of the disease.” Also, the researchers could not independently verify all medical diagnoses or assess the severity of the patients’ disease. Additionally, the findings may not apply to populations outside Finland.Larger studies looking at disease biomarkers, genetics and clinical assessments could help determine whether there is a casual relationship between the medical conditions and Alzheimer’s incidence and whether these medical patterns could be used to improve early detection.TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZFor people experiencing any persistent medical symptoms, including issues with memory or cognition, experts say it’s important to see a healthcare provider.CLICK HERE TO DOWNLOAD THE FOX NEWS APP”Early diagnosis is important because more treatment and support options are available in the early stages of the disease,” Krüger advised.”Early diagnosis also gives individuals and their families more time to plan for the future and access appropriate support services.” Melissa Rudy is senior health editor and a member of the lifestyle team at Fox News Digital.
