The Claim
Subcortical shape alterations in the thalamus and striatum can discriminate individuals with mild cognitive impairment who will progress to Alzheimer's disease from healthy controls with high accuracy (AUC >0.95), comparable to or exceeding the accuracy of left hippocampal volume measurements.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Changes in the shape of the thalamus and striatum distinguish people with mild cognitive impairment who will develop Alzheimer's disease from healthy individuals with high accuracy, matching or surpassing the accuracy of left hippocampal volume measurements.

Subcortical shape alterations in the thalamus and striatum can discriminate individuals with mild cognitive impairment who will progress to Alzheimer's disease from healthy controls with high accuracy (AUC >0.95), comparable to or exceeding the accuracy of left hippocampal volume measurements.
In people who will develop Alzheimer's disease, brain cells in the thalamus and striatum begin to shrink and lose their normal shape before memory problems become severe. These changes happen earlier and more precisely than shrinkage in the hippocampus, allowing doctors to spot who will get worse based on the shape of these deep brain areas.
What the research says
1 studyScientists found that by looking at tiny shape changes in deep brain areas like the thalamus and striatum, they could predict which people with mild memory problems would later get Alzheimer’s—with over 95% accuracy, even better than checking the size of the hippocampus.
