Treatment of functional neurological disorder: an umbrella review of systematic reviews and meta-analyses.

Functional neurological disorder causes real motor, sensory, speech, and dissociative symptoms that are among the most common reasons people are referred to neurology clinics, yet treatment approaches vary widely and evidence has been scattered across many separate reviews. This umbrella review pulled together 17 systematic reviews and meta-analyses covering psychological therapies, physiotherapy, neuromodulation, multidisciplinary rehabilitation, and medication use, comparing how consistently each approach helped and how strong the underlying evidence was. Cognitive behavioral therapy showed the most consistent benefit, particularly for functional seizures and mixed presentations, especially when delivered as part of multidisciplinary care. Physiotherapy showed moderate improvement in motor symptoms, neuromodulation showed mixed and less consistent results, and medications were mainly used to manage co-occurring psychiatric symptoms rather than the disorder itself.

The main limitation is that the underlying studies varied in quality and outcome measures, so the review's authors describe overall evidence certainty as moderate at best, with no single approach clearly established as superior.

If you or someone you know has been diagnosed with functional neurological disorder, meaning symptoms like weakness, seizures, or speech problems that arise from how the nervous system is working rather than visible damage, you may wonder which treatments actually help. Researchers combined findings from 17 earlier reviews that looked at psychological therapy, physiotherapy, brain stimulation techniques, combined rehabilitation programs, and medications. Across this large collection of research, cognitive behavioral therapy (a talk-based therapy that addresses thoughts and behaviors) consistently showed benefit, especially for functional seizures, particularly when given alongside other types of care.

Physiotherapy was linked to moderate improvement in movement-related symptoms. Brain stimulation approaches showed some promising results but these were inconsistent across studies.

Medications were mainly used to treat related mental health symptoms rather than the disorder itself. The important caveat is that the studies behind these reviews differed a lot in how they measured success and in their overall quality, so the researchers describe the evidence as only moderately certain at best, meaning no treatment can yet be called clearly superior.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

For physiotherapists navigating referrals for functional neurological disorder, a recurring clinical question is which intervention category has the firmest evidence base and how that should shape expectations around multidisciplinary planning. This umbrella review synthesizes 17 systematic reviews and meta-analyses spanning psychological therapy, physiotherapy, neuromodulation, multidisciplinary rehabilitation, and pharmacological approaches, assessing effect direction, GRADE certainty, and risk of bias across ten methodological domains. Cognitive behavioral therapy emerged with the most consistent support, particularly for functional seizures and mixed presentations, notably when embedded within multidisciplinary frameworks rather than delivered in isolation.

Physiotherapy showed moderate improvement specifically in functional motor symptoms, reinforcing its role but without establishing superiority over other modalities, since the abstract does not report direct head-to-head comparisons between intervention types. Neuromodulation results were described as promising yet inconsistent, and pharmacological treatment was characterized as adjunctive for psychiatric comorbidity rather than a primary FND treatment. As an umbrella review, this work inherits the limitations of its underlying reviews and trials, including heterogeneous outcome measures and variable risk of bias, which the authors say limited direct comparisons.

It does not establish that any single modality, or combining modalities, produces superior outcomes, and it underscores a need for standardized outcomes and more rigorous trials before firmer practice guidance can be drawn.
