Study finds 5 early signs that can appear as early as 9 years ahead of diagnosis

“When we looked back at patients’ histories, it became clear that they were showing some cognitive impairment several years before their symptoms became obvious enough to prompt a diagnosis. The impairments were often subtle, but across a number of aspects of cognition,” Nol Swaddiwudhipong, the first author of the research study, told a health journal.

“”This is a step towards us being able to screen people who are at greatest risk — for example, people over 50 or those who have high blood pressure or do not do enough exercise — and intervene at an earlier stage to help them reduce their risk,” Swaddiwudhipong said.
