Alzheimer’S Neuroimaging

Neuroimaging plays a pivotal role in diagnosing and understanding Alzheimer's disease and dementia. Techniques such as MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and CT (Computed Tomography) scans provide insights into brain structure, function, and pathology. MRI reveals structural changes like hippocampal atrophy, a hallmark of Alzheimer's. PET scans detect amyloid-beta plaques and tau tangles, proteins implicated in Alzheimer's progression. Functional MRI (fMRI) highlights brain activity patterns, aiding in understanding cognitive decline. These imaging tools not only assist in early diagnosis but also monitor disease progression and evaluate treatment efficacy. Ongoing research focuses on refining these techniques to enhance early detection accuracy and to track neurodegeneration more effectively, crucial steps towards developing therapies to manage and potentially halt Alzheimer's and dementia progression.
