Background and aimFunctional neurological disorder (FND) is a common and disabling condition for which effective treatments remain limited. Clinical outcomes are often variable, particularly in chronic and comorbid presentations. Ketamine and esketamine are increasingly used across a range of neuropsychiatric conditions. This review aimed to synthesise the existing evidence regarding their use...

Placebo effects are among the greatest paradoxes in medical research. Although more data on placebos are available from placebo-controlled trials than on any treatment in medicine, there has been comparatively little deep interrogation of issues related to their measurement, appraisal, and interpretation. Most of the work that has been done, including that in psychiatry, is narrowly focused on...

Hallucinogen persisting perception disorder (HPPD) is characterised by episodes of altered perception linked to past psychoactive drug use, accompanied by distress and functional impairment. To date, clinical characterisation has been limited in scale. Using TriNetX, a global federated health research network of electronic health records, we conducted a retrospective cohort study comparing...

Background Functional neurological disorder (FND) is a common cause of neurological symptoms including seizures and movement disorders. It can be debilitating, is associated with high health and social care costs, and can have a poor prognosis. Functional magnetic resonance imaging (fMRI) has suggested FND is a multi-network disorder. Converging evidence suggests that other mechanisms including...

Objective: Functional neurological disorder (FND) causes a high burden of disability and distress. Although it is a common disorder, there is a pressing need for improved access to evidence-based treatments. With difficulties in finding effective treatment, some people with FND may seek alternative means of symptom relief, such as legal and illicit psychoactive substances, although the...

Aims Functional neurological disorder (FND), formerly known as conversion disorder, causes a high burden of disability and distress, and is amongst the most commonly encountered conditions in neurology clinics and neuropsychiatry services, yet the therapeutic evidence base is limited. Research into psychedelics such as psilocybin and lysergic acid diethylamide (LSD) is currently being...

Functional neurological disorder (FND), formerly known as conversion disorder, causes a high burden of disability and distress, and is amongst the most commonly encountered conditions in neurology clinics and neuropsychiatric services, yet the therapeutic evidence base is somewhat limited. There has been recent interest in the therapeutic potential of psychedelics such as psilocybin and...
