Research identifies potential early indicators of Alzheimer disease

Recent medical studies are identifying potential early indicators of Alzheimer disease in specific populations. A Finnish study published in Alzheimer’s & Dementia examined health records of patients diagnosed with early-onset Alzheimer (before age 65) over a 15-year period. Researchers found that certain health issues were more prevalent in the years leading up to diagnosis, including depression, dizziness, headaches, epilepsy, and thyroid disorders. While no single symptom serves as a definitive predictor, these patterns may assist in earlier recognition.

In a separate study, researchers investigated Alzheimer’s-related changes in adults with Down syndrome. Findings suggest that levels of the blood protein β-synuclein may change approximately two decades before the onset of Alzheimer’s symptoms. Higher levels of this protein were linked to cortical atrophy and poorer memory performance, suggesting that β-synuclein testing could serve as a valuable biomarker for detecting early synaptic dysfunction in individuals with Down syndrome.
