Dynamic mental illness indicators caught by advanced AI in brain imaging

New research by Georgia State University’s TReNDS Center may lead to early diagnosis of devastating conditions such as Alzheimer’s disease, schizophrenia and autism—in time to help prevent and more easily treat these disorders. In a new study published in Scientific Reports a team of seven scientists from Georgia State built a sophisticated computer program that was able to comb through massive amounts of brain imaging data and discover novel patterns linked to mental health conditions. The brain imaging data came from scans using functional magnetic resonance imaging (fMRI), which measures dynamic brain activity by detecting tiny changes in blood flow.

“We built artificial intelligence models to interpret the large amounts of information from fMRI,” said Sergey Plis, associate professor of computer science and neuroscience at Georgia State, and lead author on the study.

He compared this kind of dynamic imaging to a movie—as opposed to a snapshot such as an x-ray or, the more common structural MRI—and noted “the available data is so much larger, so much richer than a blood test or a regular MRI. But that’s the challenge—that huge amount of data is hard to interpret.”

Frequent aerobic exercise cuts schizophrenia negative symptoms – Study

More good news on exercise this morning. Writing in the British Psychological Society Research Digest, Emma Young reports positive news on the move more section of our eat less; move more; live longer mantra.

Aerobic exercise – any activity that gets your heart pumping harder – improves mood, anxiety and memory. It can help people with major depressive disorder, bipolar disorder and anxiety disorder. Now there’s evidence, from a randomized controlled trial published in Frontiers in Psychiatry, that a program of regular aerobic exercise also reduces psychopathology in people diagnosed with schizophrenia. And it seems to have a particular impact on so-called “negative” symptoms, such as apathy and loss of emotional feeling, which are not improved by standard drug treatments.

“[W]hile antipsychotics [drug treatments] are essential in treating schizophrenia, interventions other than antipsychotic treatment…may be needed to achieve better outcomes,” write the authors of the new study, led by Peng-Wei Wang at Kaohsiung Medical University Hospital in Taiwan.
