Scientists have give you an inventory of 11 threat elements, from life-style decisions to sickness historical past, for an individual getting dementia.
They are age, training, historical past of diabetes, historical past of despair, historical past of stroke, parental historical past of dementia, deprivation, hypertension, excessive ldl cholesterol, residing alone and gender.
The checklist was whittled down from 28 identified elements linked to dementia threat, and was then used to develop a instrument lecturers say can "strongly predict" whether or not somebody will develop the situation within the subsequent 14 years.
To make the checklist, an knowledgeable group from the University of Oxford examined knowledge from greater than 223,000 folks aged between 50 and 73, which was recorded throughout two long-term UK research.
The threat elements recognized have been additionally examined alongside whether or not folks carried the APOE gene, which is thought to extend the prospect of growing dementia.
Taking this under consideration elevated the predictive functionality of the danger instrument much more, however one primarily based purely on the 11 threat issue checklist additionally carried out effectively.
The researchers consider the instrument may very well be used as an preliminary screening instrument, prioritising potential dementia sufferers for additional assessments like mind scans.
They may additionally spotlight efficient preventative measures folks can take whereas it is nonetheless doable, akin to decreasing alcohol consumption, stopping smoking, and losing a few pounds.
Previous research recommend as much as 40% of dementia circumstances may very well be prevented by way of such motion.
But lead creator Dr Raihaan Patel mentioned the instrument would want extra testing earlier than being put into common use.
"It's well known dementia risk, onset, and prevalence vary by race, ethnicity and socioeconomic status," he mentioned.
"Therefore, we need to evaluate it across more diverse groups of people both within and beyond the UK."

The threat rating additionally does not signify a "definitive outcome", the researchers confused.
Associate professor Sana Suri mentioned the significance of every threat issue varies and a few might be handled.
"While over age and APOE confer the greatest risk, modifiable factors such as diabetes, depression, and high blood pressure also have a key role," she added.
Prof Suri mentioned somebody with all three circumstances will likely be roughly thrice extra prone to develop dementia than somebody of the identical age who does not have any.
The findings have been revealed within the BMJ Mental Health journal.
