Scientists use computer diagnosis of dementia accuracy up to 96%

Keywords: Alzheimer scientists computer

London University scientists recently used computer scan from dementia brain specific injury, accuracy up to 96%. This discovery can ensure that the increase in patients with early diagnosis and treatment of the opportune time.

It is learnt that Alzheimer's is because constitute brain plaques and neurofibrillary fiber disorders, brain atrophy. Usually use diagnostic methods are not only time consuming, and difficult, and other types of dementia.

A few days ago, the London University Wei kang trust Centre for neuroimaging research team has demonstrated on dementia brain scan results. The computer can identify dementia brain specific injury, "uses computer scan and now common troubleshooting methods, it tests faster, higher accuracy, but also cheaper. "The Centre of RichardFrackowiak Professor explained that the" new method avoids human interference in making diagnosis more objective. The new method is to use the computer for dementia patients and healthy human brain scan found when comparing. Two scenarios for a single clinical magnetic resonance scan achieves highly accurate distinction. ”

The computer can be scanned by a group of normal subjects accurately locate and dementia differences, and then use the correct diagnosis is based on the results of the scan other cases. Its accuracy is better than the current best clinical practice diagnostic accuracy rate of 86 per cent. Researchers also found that they can better than clinicians better distinguish one similar to Alzheimer's Frontotemporal Dementia. Frontotemporal Dementia in many cases been mistaken for dementia.

Professor stressed that the human brain Frackowiak, after considerable damage to the brain may result in a symptom of a disease, so early to make a precise diagnosis for improving effective blocking brain degeneration is very important. "The next step is to take a look at how we can use a technique to determine the extent of the illness. "Professor Frackowiak said," so that you can use non-invasive-tool quick test reflect the new drugs treatment effect. ”
