Uncinate fasciculus degeneration refers to the deterioration or damage of the uncinate fasciculus, a bundle of nerve fibers in the brain that plays a crucial role in connecting different regions involved in language and emotion processing. In this comprehensive guide, we’ll delve into the various aspects of uncinate fasciculus degeneration, including its types, causes, symptoms, diagnostic tests, treatment options, drugs, surgeries, preventions, and when to seek medical attention.
