Problem
Automatically detecting Alzheimer's dementia from brain MRI scans to support early diagnosis.
Why it matters
Early detection of dementia affects treatment decisions and patient outcomes for a widespread disease.
What the AI did
Compared deep CNN models (ResNet, DenseNet, EfficientNet) and transformer architectures (MAE, DeiT) for classifying MRI slices into clinical diagnoses on two public datasets.
Results
Very deep ResNet and DenseNet outperformed shallow ResNet and VGG on ADNI and OASIS; no numeric metrics in abstract
Impact
Provides comparative benchmarks that may guide future computer-aided dementia detection systems.

Abstract calls AD the most common form of dementia and targets early detection via CAD; benchmark improvement up to 7% accuracy, but no scale numbers or deployment given.
Basis: inferred.
Judged from the source text, which gives no explicit scale.
Stated scale: not stated in source. Method and limits.
