Deep learning model built on neuroimaging data identifies “Brain Age Gaps” as markers of Alzheimer’s disease (AD)

by

Brain Age Gap is a Com­pos­ite Bio­mark­er for Demen­tia Pathol­o­gy or Sever­i­ty (GEN):

Mayo Clin­ic sci­en­tists have devel­oped a com­pu­ta­tion­al mod­el that pre­dicts brain age using a large col­lec­tion of neu­roimag­ing data obtained using FDG-PET (flu­o­rodeoxyglu­cose positron emis­sion tomog­ra­phy) and struc­tur­al MRI (mag­net­ic res­o­nance imag­ing). The deep learn­ing-based mod­el tests the rela­tion­ship between brain age gaps in var­i­ous forms of demen­tia, includ­ing mild cog­ni­tive impair­ment (MCI), Alzheimer’s dis­ease (AD), fron­totem­po­ral demen­tia (FTD), and Lewy body demen­tia (LBD), as well as in nor­mal brains.

Study: Wearable sensors and machine learning may well (one day) help detect a broad range of epileptic seizures

Wear­able Device Clears a First ‘Mile­stone’ in Seizure Detec­tion (Med­scape; requires subscription):

A wrist-worn device that uses machine learn­ing accu­rate­ly detects dif­fer­ent seizure types in find­ings that have the poten­tial to rev­o­lu­tion­ize the man­age­ment of patients with epilepsy.

“We have set a first bench­mark for auto­mat­ic detec­tion of a vari­ety of epilep­tic seizures using wear­able sen­sors and deep-learn­ing algo­rithms. In oth­er words, we have shown for the first time that it’s pos­si­ble to do this,” study inves­ti­ga­tor Jian­bin Tang, MA, Data Sci­ence Project Lead, IBM Research Aus­tralia, Vic­to­ria, told Med­scape Med­ical News.

“In 2012, when Angry Birds was in its prime, Seung had an inspiration.

“What if,” he won­dered, “we could cap­ture even a small frac­tion of the men­tal effort that goes into Angry Birds (for brain map­ping)? Think of what we could do.” [Read more…] about From Angry Birds to brain map­ping: The Gam­i­fi­ca­tion of Neuroscience
