Background and purpose: In 2021, the European Academy of Neurology's training requirements were updated to include functional neurological disorder (FND) as a core topic for the first time. To reinforce these changes, we aimed to understand the proportion of inpatients (in non-neurology settings) who are diagnosed with FND.
Methods: We prospectively collected data on diagnoses made after inpatient ward reviews from neurology trainees at three tertiary neurology centres in Scotland from April to September 2021. We assessed healthcare utilization data for patients with a diagnosis of FND, epilepsy and epileptic seizures, or a neuroinflammatory disorder over the preceding 12 months.
Results: There were 437 inpatient reviews for 424 patients by 13 trainees. The largest single diagnosis was FND (n = 80, 18%), followed by epilepsy (n = 64, 14%), primary headache disorder (n = 40, 9%) and neuroinflammatory disorders (n = 28, 6%). There was an uncertain diagnosis for 48 reviews (11%). Compared to patients with epilepsy or neuroinflammatory disorders, patients with FND had a similar number of admissions (2 vs. 2 vs. 1) and brain/spine imaging studies (2 vs. 1 vs. 2).
Conclusions: In Scotland, FND was the most common diagnosis made after a request for an inpatient review by a neurologist from another department in the hospital. Patients with FND have similar health resource needs to those with other common neurological disorders when they present to hospitals with tertiary neurology centres. This data supports the inclusion of FND as a core curriculum topic in neurology training.
