Immune response in nervous system diseases

The immune response in nervous system diseases involves the body's defense mechanisms reacting to infections, injury, or abnormal cells in the brain and spinal cord. When the nervous system is affected, immune cells can either help repair damage or, in some cases, mistakenly attack healthy nerves, leading to further problems. Conditions like multiple sclerosis or Alzheimer's showcase this dual role of the immune system: while it aims to protect and heal, it can also contribute to disease progression if it becomes dysregulated. Understanding this balance is crucial for developing effective treatments for neurological disorders.
