Psychosis

Who is involved in our studies?

The term ‘psychosis’ encompasses a number of symptoms associated with significant alterations to a person’s perception, thoughts, mood and behaviour. Individuals experiencing psychosis will have a different combination of symptoms, which may include:

  • Hallucinations, Delusions, Disorganised speech and/or thoughts;
  • Social withdrawal, reduced speech, self-neglect,
  • Difficulties remembering things, staying focused on things such as tasks, conversations or trying to figure out how to do something.

At Oxford Health, researchers are investigating the different types of causes underpinning experiences in psychotic disorder the aim of developing better treatments.

Previous research suggests that there are a range of different factors that lead an individual to develop psychosis. These include:

  • Psychological: how we see ourselves, very high stress and worry levels
  • Social: difficult life experiences, taking illicit drugs
  • Biological: how our brain functions
  • Genetic: some people are more vulnerable than others due to their genetics

Schizophrenia is the most common psychotic disorder, however we now know that there are a range of other psychotic disorders.

Current research

We have a variety of different studies. Some involve a questionnaires, some involve a therapy and some involve taking a medication.  Some take place in our research clinics, in a clinical team base or sometimes they can take place in your home.

We are sometimes able to contact people directly about research, or get referrals from clinical teams. We are always appreciate hearing from people who are interested in getting involved.

Current Studies

CLEAR

Principal Investigator: Dr Antony James- Consultant Psychiatrist

Objective: The trial will assess whether Clozapine is more effective than treatment as usual in people 12-25, at the level of clinical symptoms, patient related outcomes, quality of life and cost effectiveness.

 

DPIM

Principal Investigator: Dr Digby Quested- Consultant Psychiatrist

Objective: To find genetic or other cause of mental illness by studying DNA in the blood or saliva .

 

Early Intervention Mission

Principal Investigator: Professor Belinda Lennox – Professor of Psychiatry

Objective: To understand more about psychosis by comparing information collected from individuals with psychosis to the general population. Information will be collected from medical records, a blood sample and other questionnaires.

 

Feeling Safer

Principal Investigator : Dr Daniel Freeman- Consultant Clinical Psychologist

Objective: Aiming to understand if a new online programme can reduce persecutory delusions in people with psychosis. The programme involves personalised modules to tackle the psychological processes that maintain persecutory delusions.

 

GlobalMinds

Principal Investigator: Dr Philip McGuire

Objective: To develop an internationally diverse bioresource linking genetic and healthcare information in individuals with schizophrenia, psychosis, depression or bipolar.

 

Investigating Neural Basis for Psychosis

Local Collaborator: Professor Belinda Lennox – Professor of Psychiatry 

Objective: Investigating how memory formation and consolidation processes are altered in individuals with First Episode Psychosis using functional neuroimaging.

 

MAPS- MENSTRUAL CYCLE AND PSYCHOTIC SYMPTOMS

Principal Investigator: Dr Thomas Reilly

Objective: This study aims to measure how mental health symptoms changes across the menstrual cycle.

 

moreRESPECT

Principal Investigator: Abiola Jokomba – Ward Manager

Objective: To understand if a tailored sexual health intervention able to reduce unprotected sexual acts and increase knowledge about sexually transmitted diseases and healthy relationships.

 

Neurocrine

Principal Investigator: Professor Rachel Upthegrove

Objective: To evaluate the efficacy of NBI-1117570 compared with placebo on improving behavioural and psychological symptoms of
schizophrenia in adults who warrant inpatient hospitalization. To evaluate the safety and tolerability of NBI-1117570 in
participants with schizophrenia

 

PEACE

Principal Investigator: Dr Daniel Maughan – Consultant Psychiatrist

Objective: To explore the cause of cognitive symptoms of schizophrenia by measuring brain activity using brain scans.

 

PPIP2

Principal Investigator: Professor Belinda Lennox – Professor of Psychiatry

Objective: To test enough patients with psychosis to be able to define the prevalence of schizophrenia that is caused by an antibody mediated disorder. Patients can opt into SINAPPS2 if blood test is positive.

 

Sleeping Better

Principal Investigator: Dr Daniel Freeman – Consultant Clinical Psychologist

Objective: We are offering a 12 week cognitive-behavioural sleep intervention for individuals with a diagnosis of psychosis or at ultra-high risk for psychosis. We aim to improve sleep, mood, psychiatric symptom and overall functioning.

 

SMILE

Principal Investigator: Professor Rachel Upthegrove – Professor of Psychiatry

Objective: To investigate the genetic and environmental interactions of people with psychosis spectrum disorders. All participants will be re-contactable and join the NIHR BioResource, offering participants relevant research opportunities in the future.

 

Tri-Prep

Principal Investigator: Dr Andrew Molodynski

Objective: investigate the views, understandings and perspectives of people with severe mental illness (SMI) and mental health professionals (MHPs) on smoking, smoking reduction and cessation, and vaping. This study will inform the design of future research on helping people with severe mental illness to reduce smoking, finding out how we can make our research acceptable and suitable for participants

 

Vision Quest

Principal Investigator: Cristina Sanchez Pascual – Senior Clinical Research Assistant

Objective: One in three people with psychosis experience visions, also know as visual hallucinations. Surprisingly little is known about these experiences. The study aims to develop our understanding of visions in two ways. 1- Develop a new measure exploring people’s belief’s about visions. 2-Explore the relationships between visions and other issues such as poor sleep and high worry.
