Cortical Atrophy

Cortical atrophy refers to the gradual loss or shrinkage of the brain’s outer layer, called the cortex, which is vital for functions like thinking, memory, and decision-making. This tissue loss can occur due to aging, neurological diseases such as Alzheimer’s, or other brain conditions. As the cortex thins, it can lead to difficulties with memory, reasoning, and coordination. The extent and location of atrophy influence how symptoms present. While some degree of cortical shrinkage can be a normal part of aging, significant atrophy often indicates underlying pathology requiring medical attention.
