Learning objectives This paper aims to familiarise radiologists with basic anatomical, pathophysiological, and clinical notions of Alzheimer’s disease, the neuroimaging modalities, and specific findings of this condition. Furthermore, we highlight deep-learning-based algorithms with applications in earlier diagnosis, development of prediction models, and treatment research.
Read more Background According to WHO, dementia affects more than 55 million people worldwide, being the seventh global cause of death, with approximately 60-70% of cases attributed to Alzheimer’s disease (AD). It represents a significant burden on patients, informal caretakers, and global economies. [1] AD is a neurological disorder characterized by a progressive decline of cognitive abilities leading to severe impairment. It is triggered by the accumulation of amyloid-β (Aβ) and tau neurofibrillary tangles (NFTs) with a specific distribution pattern, causing disruption and...
Read more Findings and procedure details Neuroimaging Modalities in ADStructural MRI can assess the degree of brain tissue loss or damage in key regions like the medial temporal lobe (MTL) in the early stages, and the neocortex as the disease progresses. It also helps differentiate AD from other forms of dementia and has great utility in monitoring disease progression, allowing for therapy-response evaluation and adjustments.[3,4,5] [fig 2] Brain atrophy is an inevitable consequence of neurodegeneration and an accurate marker of structural brain changes. The earliest MRI changes appear...
Read more Conclusion Neuroimaging plays a key role in diagnosing and monitoring AD, as it depicts neuropathological, structural, and functional changes even from the early stages. The recent development of AI and deep-learning-based software provide amazing automated, time-saving solutions that significantly aid neuroradiologists in catching the disease early, staging it accurately and monitoring the evolution and treatment response. AI-based solutions should rapidly find their way into AD routine clinical practice, as they will improve patient’s quality of life.
