Picture this: you’re exploring a complex maze, searching for hidden treasures. Suddenly, you stumble upon a map that reveals the secret pathways and interconnected routes within the maze. In a similar way, scientists are using functional magnetic resonance imaging (fMRI) to unravel the intricate network of brain activity in Alzheimer’s disease (AD). AD is like a mysterious maze with no cure, but early detection and intervention are key to slowing its progression. With ADAD, a form of AD that runs in families, researchers have a unique opportunity to study the earliest signs and biomarkers of the disease. By studying fMRI scans, scientists have discovered abnormal patterns of brain activity in regions like the hippocampus, medial temporal lobe, posterior cortex, cingulate cortices, and frontal regions – all important players in memory and cognition. Interestingly, these fMRI changes in ADAD closely resemble those seen in sporadic AD (SAD), but not in normal aging. This suggests that understanding the neural networks at play in ADAD can provide valuable insights into both familial and sporadic forms of the disease.

Alzheimer’s disease (AD) is the most common form of dementia, with no cure to stop its progression. Early detection, diagnosis, and intervention have become the hot spots in AD research. The long asymptomatic and slightly symptomatic phases of autosomal dominant AD (ADAD) allow studies to explore early biomarkers and the underlying pathophysiological changes. Functional magnetic resonance imaging (fMRI) provides a method to detect abnormal patterns of brain activity and functional connectivity in vivo, which correlates with cognitive decline earlier than structural changes and more strongly than amyloid deposition. Here, we will provide a brief overview of the network-level findings in ADAD in fMRI studies. In general, abnormalities in brain activity were mainly found in the hippocampus, the medial temporal lobe (MTL), the posterior cortex, the cingulate cortices, and the frontal regions in ADAD. Moreover, ADAD and sporadic AD (SAD) have similar fMRI changes, but not with aging.
