'Brain fog' is commonly reported in more than a dozen chronic diseases, but what it? We review research across conditions which has characterised brain fog and evaluate its definitions objective correlates. Brain been used to refer variable set of overlapping symptoms implicating cognition, fatigue, affect. It defined as distinct symptom, syndrome, or nonspecific term. consider the evidence that transdiagnostic entity with common phenomenology profile cognitive deficits. discuss where these commonalities arise argue linguistic ambiguity, shared impairments, noncognitive factors are likely neurobiology. suggest how future might apply existing tools disambiguate phenomena conflates.

The underlying mechanisms of functional cognitive disorder (FCD) are still poorly understood. This hinders diagnostic identification and establishment personalised effective treatments. We aimed to describe the precipitating factors for new-onset FCD explore differences between acute gradual onset groups.

Only with at least one-year symptom duration were included. extracted mode factors, demographics, comorbidities, family history symptoms, personal exposure dementia, trajectory, as well testing when available. Ninety-three included, which 45 had an symptoms (48% total). Of group, 51% female; mean age was 44 years (± 12). In COVID-19 (n = 18, 40%), head injury 16, 36%) migraine most common onset, followed by cardiovascular/vasovagal events, dissociative episodes, panic, medication change, medical procedure under sedation vertigo. group younger, commonly fluctuating course more headache fatigue than group. Functional often begins acutely. circumstances around may have treatment prognostic implications. Similar other disorders, experience abnormal cognition from pathophysiological event can act powerful disorder.
