Alzheimer's predicted by MRI
Wednesday 6th April 2011
MRI scans could be used to detect mild cognitive impairment that is likely to progress into Alzheimer's disease, a new study has indicated.
The scanners are able to detect the cortical thinning associated with the neurodegenerative condition, according to the research, published in journal Radiology.
People with mild cognitive impairment develop Alzheimer's at a rate of 15 to 20 per cent per year, which is much more than the one to two per cent rate seen in the general population.
Researcher Linda K McEvoy from the University of California, San Diego, said: "Compared to estimating a patient's risk of conversion based on a clinical diagnosis only, MRI provides substantially more informative, patient-specific risk estimates."
This comes after comments from the Alzheimer's Society which called for the routine dementia screening of people over the age of 75.
According to the society's figures, around 750,000 people are living with dementia in the UK but more than half of these have not yet been diagnosed.
