Atrophy in Alzheimer’s Disease refers to the loss of brain cells (neurons) and the connections between them, leading to a reduction in brain volume. This neurodegenerative process primarily affects areas of the brain crucial for memory and cognitive function, such as the hippocampus. Common symptoms associated with this condition include progressive memory loss that disrupts daily life, challenges in planning or solving problems, difficulty completing familiar tasks, confusion with time or place, and changes in mood or personality. MRI scans are instrumental in detecting brain atrophy. While some brain shrinkage is a normal part of aging, MRI can reveal patterns of atrophy that are more severe than expected for age, particularly in regions like the medial temporal lobe, which are characteristic of Alzheimer’s Disease. MRI is more sensitive than CT scans in visualizing these subtle changes and can help differentiate Alzheimer’s-related atrophy from other conditions.
