By Neha MathurAug 24 2023Reviewed by Lily Ramsey, LLM In a recent systematic review published in BMC Neurology, researchers examined recent studies exploring neuroimaging modalities aided by advanced machine learning algorithms that predicted Alzheimer’s disease progression from mild cognitive impairment to AD dementia.
Background AD is a progressive neurodegenerative disorder that begins decades before clinical diagnosis. AD-related damage to neurons and their connections hampers the daily life activities of the affected individuals, such as swallowing, walking, and talking. However, combining these modalities to obtain a more comprehensive understanding of structural and functional brain data is challenging, given the complexities of integrating multiple measures associated with the transition from MCI to AD dementia.
Related StoriesAll included studies used at least one type of neuroimaging modality, preferably using biomedical image processing with ML techniques, described the methodology in detail for enabling replication, and results in a way that facilitated the extraction of the accuracy, sensitivity, and specificity of the method used for comparison purposes.
Results The majority of studies screening MCI patients at risk of AD dementia used structural MRI and PET scans. While these neuroimaging modalities returned data with high spatial resolution, these systems are expensive, tedious to maintain, and immobile, which limits the utility of prediction tools using these modalities.
Further, most studies monitored the MCI to AD transition over a short time window of 6-36 months, implying some individuals classified as stable MCI had progressed to AD dementia already.

Researchers identify mathematical rule behind the distribution of neurons in our brainsHuman Brain Project (HBP) researchers from Forschungszentrum Jülich and the University of Cologne (Germany) have uncovered how neuron densities are distributed across and within cortical areas in the mammalian brain. They have unveiled a fundamental organizational principle of cortical cytoarchitecture: the ubiquitous lognormal distribution of neuron densities.
