infection-associated chronic illnesses would be of particular interest, although this is not a requirement (i.e., applications can focus on a single condition). Neurologically focused clinical research investigating scientifically compelling pathways that contribute to the development of infection-associated chronic illnesses - including basic experimental studies in humans (BESH) or mechanistic clinical trials that will accelerate the development of effective treatments - are within the scope of this initiative. Preclinical studies utilizing animal, cell culture, and/or human tissue models are also encouraged. All applications must propose such studies in the context of a post-infectious etiology.
