Neuroimaging is a powerful tool that helps us see how Alzheimer’s Disease (AD) affects the brain. It allows doctors and researchers to spot changes related to the disease.
Here are some important things we’ve learned from neuroimaging:
Brain Shrinkage: Many people with Alzheimer’s Disease, more than 90%, experience brain shrinkage. This is especially true for a part of the brain called the hippocampus, which is important for memory.
Amyloid and Tau Detection: Using a special type of imaging called Positron Emission Tomography (PET), we can see sticky proteins called amyloid beta. These proteins are found in about 70-80% of people who have mild cognitive impairment. This condition can be a sign that Alzheimer’s may develop later.
Brain Network Changes: Another imaging method called functional MRI shows that the connections between different parts of the brain change. This is seen in 60-70% of patients during the early stages of Alzheimer’s Disease. One important network affected is called the default mode network, which is involved in thinking and remembering.
Predicting Memory Loss: Neuroimaging can also help predict when a person might experience memory loss. It can do this with about 80% accuracy based on early brain scans.
In summary, neuroimaging gives us valuable information on how Alzheimer’s Disease develops, helping us understand the changes in the brain and predict future issues with memory and thinking.
