Chronic neuroinflammation is implicated in the propagation of 'brain fog', a colloquial term used to describe a heterogeneous set of cognitive issues, including brain-based fatigue, effortful cognition, poor focus, and forgetfulness. Complaints of brain fog and other cognitive inefficiencies have increased in frequency in a wide range of seemingly unrelated neurological and psychiatric conditions, including multiple sclerosis, lupus, long COVID, and depression, among others.

Although the impact of brain fog on cognition is typically of low severity, the impact on daily functioning, work capacity, and quality of life can be devastating, considering it can affect individuals of workforce age. Additionally, patients with brain fog symptoms can burden on the medical system through increased healthcare utilization.

Brain fog can be triggered or exacerbated by a myriad of physical, lifestyle, and behavioral issues, including poor diet. Recent evidence suggests that nutrition interventions aimed at addressing the underlying drivers of neuroinflammation can reduce brain fog and improve cognitive outcomes. In this session, experts will discuss a possible consensus operational definition, the objective measurement, and use of evidence-based nutritional interventions for the treatment of 'brain fog'. Participants will come away with specific tools and recommendations for patients and clients.
