AI spots Alzheimer's brain changes years before symptoms emerge

New Scientist

Artificial intelligence can identify changes in the brains of people likely to get Alzheimer's disease almost a decade before doctors can diagnose the disease from symptoms alone. The technique uses non-invasive MRI scans to identify alterations in how regions of the brain are connected. Alzheimer's is a neurodegenerative disease that is the leading cause of dementia for the elderly, eventually leading to loss of memory and cognitive functions. The race is on to diagnose the disease as early as possible. Although there is no cure, drugs in development are likely to work better the earlier they are given.

Early diagnosis can help patients make lifestyle changes which may help slow the progression of Alzheimer's. A devastating chronic neurodegenerative disease, Alzheimer's disease (AD) currently affects around 5.5 million people in the United States alone. Causing progressive mental deterioration, it ultimately advances to impact basic bodily functions such as walking and swallowing. Looking for a way to help, researchers at the University of Bari and Istituto Nazionale di Fisica Nucleare in Italy have developed new machine learning AI technology that may help identify Alzheimer's a decade before doctors usually can, by way of non-invasive MRI brain scans. An early diagnosis -- before any of the symptoms a doctor might recognize become apparent -- could give patients a chance to make changes to their lifestyle which may slow Alzheimer's progression.

"We used this cohort to feed [our] artificial intelligence, then an independent test of about 148 subjects -- including controls, Alzheimer's disease and mild cognitive impairment (MCI) subjects -- was performed.


Artificial intelligence can detect Alzheimer's decade before symptoms emerge

Artificial intelligence (AI) can identify Alzheimer's disease 10 years before doctors can discover the symptoms, according to new research. A team of researchers in Italy developed an algorithm that can spot structural changes in the brain that are caused by the disease a decade before the signs become apparent. The team from the University of Bari trained the AI by feeding in 67 MRI scans - 38 from Alzheimer's patients and 29 healthy patients - then asked it to analyse the neuronal connectivity to form an algorithm. Following the training, the AI was then asked to process brains from 148 subjects - 52 were healthy, 48 had Alzheimer's disease and 48 had mild cognitive impairment (MCI) but were known to have developed Alzheimer's disease two and a half to nine years later. According to the researchers, the AI diagnosed Alzheimer's disease 86 per cent of the time.


AI Can Detect Signs Of Alzheimer's Years Before Symptoms Develop

Depending on the stories you read, artificial intelligence (AI) can be absolutely terrifying or downright hilarious (or both). Sometimes it can be lifesaving. Scientists are constantly discovering new ways this exciting technology can be used to improve our health and extend lifespans, whether that's software to detect skin cancer or a program that can pick the most viable embryo option for IVF treatment. Now, researchers are using AI scans to detect Alzheimer's almost a decade earlier than doctors making a diagnosis based on symptoms alone. Alzheimer's is the most common form of dementia, affecting over 5 million Americans.
