A major study reveals that common health conditions like diabetes, thyroid problems, digestive issues, and vitamin deficiencies may raise the risk of Alzheimer’s or Parkinson’s years before symptoms begin.
Researchers examined 155 conditions and found that certain problems, especially Type 2 diabetes, gastritis, and deficiencies in vitamin D and B vitamins, were more common in people who developed these brain diseases later. The risks were strongest when these conditions showed up 10 to 15 years before diagnosis.
The findings highlight how long-term brain health may be influenced by early issues related to hormones, the gut-brain connection, and metabolic function. Experts say these results reinforce the idea that cognitive decline often starts well before memory loss or tremors appear.
Doctors believe this research could change how we approach prevention. Instead of waiting for symptoms, future care might focus on tracking common health markers like blood sugar, thyroid levels, and nutrient status. Since Alzheimer’s and Parkinson’s affect millions of people, catching risks early could offer new ways to delay or avoid these serious conditions.
