Laser test ‘could detect different types of dementia in seconds’

A caller trial that uses lasers to observe antithetic types of dementia in conscionable seconds could revolutionise however the illness is diagnosed, scientists person said.

Researchers astatine the University Hospital Southampton (UHS) and the University of Southampton are starring a survey that analyses blood, spinal fluid oregon mucus utilizing lasers to place radical with dementia aboriginal successful the disease.

Dementia tin instrumentality up to 2 years to diagnose but this laser-based method is cheaper than existent tests and tin supply results successful conscionable seconds, the researchers said.

Initial tests person shown it tin observe Alzheimer’s illness with an mean accuracy of much than 93%, they added.

Professor Chris Kipps, advisor neurologist astatine University Hospital Southampton, said the caller method represents ‘a breakthrough successful aesculapian technology’ and could ‘change the mode we attack dementia diagnosis’.

He said: ‘This innovation is not conscionable a leap successful healthcare quality; it’s a paradigm shift, redefining our attack to neurodegenerative illness successful the clinic.’

More than 850,000 radical are surviving with dementia successful the UK, with numbers expected to emergence to 1.4 cardinal by 2040.

There are galore antithetic types of the condition, specified arsenic Alzheimer’s and vascular dementia, which is progressive and gets worse implicit time.

Diagnosing dementia tin instrumentality much than 2 years with existent diagnostic tools, which tin see encephalon scans and representation tests.

Many radical bash not person a diagnosis until a overmuch aboriginal signifier successful the illness erstwhile attraction options are little effective, the researchers said.

They said 1 of the main challenges is distinguishing betwixt closely-related dementia types.

The anticipation is that the caller technology, known arsenic multi-excitation Raman spectroscopy (MX-Raman), volition make what the researchers telephone a ‘biochemical fingerprint’ of a idiosyncratic to assistance pinpoint the benignant of dementia.

Professor Sumeet Mahajan, prof of molecular biophotonics and imaging astatine the University of Southampton, said: ‘Our integrated attack has the imaginable to revolutionise dementia diagnostics.

‘There is an urgent unmet objective request for much discriminatory, businesslike and cost-effective solutions.

‘Our holistic MX-Raman method is uniquely equipped to code these challenges and we privation to spot this exertion pb to vastly improved diligent outcomes.’
