Research themes

Our research studies are linked to our research themes. They're the different areas where we carry out our research. Each theme is led by a theme leader, who has links with our local universities and Sussex Partnership. 

Click on the links below for further details about our research themes.

Theme lead

Dr Sam Robertson, Lead for Service User and Carer Involvement at Sussex Partnership and Chair of the Lived Experience Advisory Forum (LEAF).

The Approaches to Involvement and Recovery theme aims to deliver and develop research focused on the involvement of lived experience experts in mental health research. 

We believe that no research study in the NHS should be funded without a patient involvement component - please contact us for further details.
Areas of interest

Mental health recovery research

  • Research into mental health service provision that involves service users, carers, peers and staff
  • Using innovative ways to reach out to all parts of the community, particularly underrepresented groups: Our Patient Participation and Involvement café, runs in physical and virtual formats to connect and chat about research
  • The impact of involvement.

Research projects

  • Peer Emotional Labour (PEL) looking at the emotional labour of involvement and recovery. Read about the Applied Research Collaboration Kent, Surrey and Sussex Individual Development Award which supported this PEL research.
  • The OUTSIDE study looking at outdoor swimming as a nature-based intervention for depression. See more here
  • ENRICH is a project which evaluated whether peer support workers are helpful for people being discharged from hospital. Service users, carers, peers and staff were the researchers in this project
  • The LETS project asked participants to share their experiences of taking part in research. Reasons for taking part were for a sense of hope, identity, meaning, empowerment and connectedness
  • INDEED is a project within the Time for Dementia study where we use film as a memory aid for participants to recall their sessions.

Key publications

The Youth Patient and Public Involvement Café

  • Abigail Thomson MSc, Edward Peasgood, Sam Robertson PhD
  • Published September 2022

A youth-led model for meaningful involvement with children and young people.

This open access paper is written by a team of young people who developed and worked on the Youth PPI Café over a period of 18 months. They reflected on their experiences, providing examples of how youth involvement and co-production could be effectively delivered in practice.

By working 'with' young people, rather than 'for' them, we offer insights into the successes and challenges of an entirely youth‐led involvement space, for research, and for young people, e.g. skills development, tokenism, resourcing and diversity and inclusion.

Theme leads

Professor Hugo Critchley

Consultant Psychiatrist, Sussex Partnership NHS Foundation Trust.  Lead for the Neurobehavioural Clinic (His specialist clinical service evaluates neurodevelopmental conditions in adults). Co-Director of the Sackler Centre for Consciousness Science; Brighton and Sussex Medical School (BSMS). Head of the Department of Neuroscience, BSMS.

Dr Alessandro Colasanti

Lead for the Immunopsychiatry Clinic. Senior Lecturer in Psychiatry, Brighton and Sussex Medical School

Areas of interest

The Brain and Body research explores the links between physical and mental health such as:

  • The relationship between hypermobility and mental health, particularly anxiety
  • Applying insights from immunopsychiatry to better understand ME and chronic fatigue syndrome
  • Looking at why the insular system is hyperactive in people with Tourette's
  • Interoceptive awareness (consciousness of internal bodily state)
  • Role of brain mitochondrial function and oxygen metabolism in the pathophysiology of mood disorders
  • Imaging of neuroinflammation and Immunopsychiatry research
  • PET studies on brain endogenous opioids.

The theme is a working collaboration with the University of Sussex and Brighton and Sussex Medical School. 

Theme objectives

Researchers within the Brain and Body theme are working on a range of studies exploring the way mind and body are dynamically linked and hope that by understanding these relationships, better, targeted and personalised treatments can be developed

The theme seeks to explore new advances in neuropharmacology and the treatment of neurobehavioural problems such as Attention Deficit Hyperactivity Disorder and autism. By seeking to understand the causes of severe and disabling brain disorders they aim to improve clinical care by developing new and better ways to treat them. 


ADIE - Breaking the link between autism and anxiety. ADIE is a £1m-funded study by MQ. Researchers led by Prof Critchley are looking at if a new psychological therapy could reduce the number of people with high-functioning autism from going on to develop an anxiety disorder.

ADAPT- looking at a new therapeutic intervention for anxiety in hypermobility.

Cap-Mem - exploring the cause and prevalence of memory problems

Role of interoception in Multiple Sclerosis fatigue

LQD - comparing the clinical and cost-effectiveness of Lithium and Quetiapine for treatment-resistant depression.

OxyBipolar - combining pharmacology and novel neuroimaging techniques in patients with treatment-resistant bipolar disorder, this study aims to investigate the effects of Methylene Blue (an antioxidant drug with neuroprotective properties) on brain biogenetics and brain oxygen metabolism.

Immune cells in the brain (microglia) are known to be overactive in some people with depression. Using PET scans, we are measuring how microglial cells respond when they are triggered by an immune response in the body.

Theme lead

Prof Naji Tabet, Reader in Old Age Psychiatry (Neuroscience and Imaging) Brighton and Sussex Medical School, Director of the Centre for Dementia studies.

Lead for the Living Well with Dementia research theme, Applied Research Collaboration Kent, Surrey and Sussex (ARCKSS).

The Dementia and Older People’s Mental Health theme includes several studies exploring the issues of old age including clinical trials for Alzheimer’s disease. Research areas include immunological and biochemical markers in dementia; non-pharmacological and lifestyle interventions in dementia disorders. The theme is a working collaboration with University of Sussex, Brighton and Sussex Medical School and University of Brighton.

Theme objectives

Dementia research is important because it's only through research that underlying causes and living with the disease can be fully understood. We aim to find treatments that help people to live well with dementia.

Research projects

Time for Dementia is an educational programme which is built on a teaching approach for understanding long-term conditions, in this case, dementia. It aims to improve the knowledge, understanding, attitudes and behaviour towards dementia in trainee healthcare professionals. It does this by pairing students with people with dementia (and their carers) for visits over a period of three years so they can gain a genuine understanding of life with dementia, which they can take forward with them in their healthcare careers. This programme is being evaluated, with student and family outcomes being measured and can also be rolled out for other conditions.

PhysiQOL assesses the impact of lifestyle factors, such as physical activity, on the quality of life of people with dementia.

FREE-COG is a project which has produced a validated copyright-free (cost-effective) cognitive testing tool for healthcare settings.

Measuring Carer Quality of Life (C-DEMQOL) - Development of a questionnaire that can be used by researchers and clinicians to gain a greater understanding of the quality of life of carers of people with dementia.

We also host several commercial (drug) trials at our Dementia Research Unit.
