Family members could be a better judge of whether a person has Alzheimer's or dementia than traditional testing, it has been suggested.
Researchers believe that giving friends or family members a questionnaire, rather than testing suspected Alzheimer's sufferers themselves, could be a more effective evaluation.
A study carried out to test the viability of using this questionnaire as an alternative testing method was carried out by scientists at Washington University, who found that the so-called AD8 two-minute evaluation corresponded with biological indicators and biomarkers for Alzheimer's disease.
Commenting on the findings, which are published in the journal Brain, Washington University School of Medicine's John C Morris and Joanne Knight said: "The AD8 gives us a brief and very low-cost alternative that takes a few minutes of the informant's time to screen for dementia and thus identify those individuals who need follow-up evaluations to determine if there truly are signs of Alzheimer's."
Earlier this week, charity Dementia UK urged more help for carers and people close to those who develop dementia.
