Imaging in Autoimmune Neurology

Abstract

Autoimmune disorders are becoming increasingly recognized within the broader field of neurology. The discovery of multiple, novel, neutrally targeted autoantibodies over the past decade and their translation into commercially available testing, in particular, has aided in the more rapid diagnosis of these disorders. When considering imaging in autoimmune neurologic disorders, it is important, when possible, to visualize the autoimmune process itself, as well as to make sure that the patient does not have an associated malignancy driving the overall process. Positron emission tomographic scans can aid in the detection of small tumors with limited spread, as well as in the visualization of autoimmune processes affecting the brain and/or spinal cord. In autoimmune disorders of the central nervous system, imaging abnormalities can appear within the limbic system, extralimbic areas, and spinal cord. Such imaging abnormalities can serve as objective markers to follow over time to assess patients' responses to treatment. It is important to recognize that overlapping syndromes (for instance, both demyelinating and autoimmune or both infectious and autoimmune) exist and that inflammatory disorders can leave behind sequelae that can be r...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.
