Neuropathology is the study of diseases affecting the nervous system, particularly the brain and spinal cord. It involves examining tissues and cells to understand how various conditions, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis, impact neurological function. Neuropathologists use techniques like biopsies and autopsies to identify abnormalities and diagnose diseases. This field plays a crucial role in medical research and diagnosis, helping to uncover the underlying mechanisms of neurological disorders. By analyzing brain tissue, neuropathologists can provide insights into disease progression and potential treatment options, contributing to advancements in neurology and neuroscience.
