Overview
Brief Summary
The goal of this study is to learn about the brain network response in people who have functional neurological disorder who are administered with a single dose of the psychedelic psilocybin with therapeutic support.
The main question it aims to answer is:
Can the default mode network, a brain network thought to be relevent in FND, be modified by the administration of psilocybin based on functional magnetic resonance imaging before and after the dose?

Eligibility Criteria
Inclusion Criteria
- •Age 25 - 60 years.
- •Fluent in the English language
- •A diagnosis of FND from a neurologist and/or neuropsychiatrist as per DSM-5 criteria
- •Moderate or severe symptoms (≥4 on Clinical Global Impression Severity (CGI-S) scale) which have been present for \>12 months and have failed to respond to best available treatment.
- •Able to tolerate fMRI scanning procedures.
- •Failed to respond is defined as an inadequate response to a full course of FND-specific therapy, including psychological therapy (cognitive behavioural therapy) or physiotherapy. Either therapy must have been undertaken by a suitably trained expert in FND and must have been specifically targeted at FND symptoms.
Exclusion Criteria
- •Diagnosis of severe depression (defined as meeting DSM-5 criteria) on the MINI 7.
- •Positive diagnoses on the MINI will be subject to confirmation at clinical interview by a psychiatrist.
- •Diagnosis of bipolar affective disorder (defined as meeting DSM-5 criteria for bipolar I or bipolar II) on the MINI 7.
- •Positive diagnoses on the MINI will be subject to confirmation at clinical interview by a psychiatrist.
- •Diagnosis of a psychotic disorder (defined as meeting DSM-5 criteria) on the MINI 7.0, EXCEPT substance/medication induced psychotic disorder where the duration was limited to the acute period of direct intoxication with the substance/medication. Positive diagnoses on the MINI will be subject to confirmation at clinical interview by a psychiatrist.
- •Diagnosis of drug or alcohol dependence disorder (defined as meeting DSM-5 criteria) on the MINI 7.
- •Positive diagnoses on the MINI will be subject to confirmation at clinical interview by a psychiatrist.
- •Diagnosis of a personality disorder (defined as meeting DSM-5 criteria) on the MINI 7.
- •Positive diagnoses on the MINI will be subject to confirmation at clinical interview by a psychiatrist.
- •Diagnosis of any dementia (defined as meeting DSM-5 criteria for any dementia disorder) based on clinical interview by a psychiatrist.
