Bridging Gaps in Research

Through a coordinated research effort involving patients, clinicians and researchers, the Brain Inflammation Collaborative strives to uncover connections between brain inflammation and mental and physical health and make advances in the diagnosis, treatment and prevention of neuroinflammatory illness.

Uncover hidden connections between inflammation and mental health with patient-reported outcomes that leverage wearables, and validated assessments on the Unhide™ Platform for groundbreaking research insights.

The Unhide Project is an ongoing online clinical study that assembles patient-donated data to help clinicians and researchers accelerate breakthroughs surrounding brain inflammation and mental health.

The relationship between brain inflammation and mental health is vastly understudied and misunderstood. The Brain Inflammation Collaborative is leading the charge to change that. Discover all the different ways you can support our mission to find long-overdue answers and solutions for patients.

Rethinking Brain Inflammation: A New Era of Research

The impact of brain inflammation on both the body and the mind has received serious recognition in only the last decade, when researchers started investigating the high rates of depression and anxiety in patients with chronic inflammatory conditions.

What is inflammation?

Inflammation is a condition where the immune system’s white blood cells and the chemicals that they produce accumulate in the body. It can be a reaction to an infection or injury, and it helps protect against invaders like bacteria or viruses. It can be acute (short lived) like when you catch a cold and have a sore, inflamed throat. In some cases, it can become chronic (lasting a long time), like with some types of arthritis. Sometimes, inflammation happens because the immune system becomes unregulated and flares up when it is not needed. And in some illnesses, the immune system can even get confused and attack healthy parts of the body, which is called auto-immunity. 

Classically, we expect inflammation to show with swelling, redness, pain, and warmth of a part of the body (as with an infected cut), or whole body effects like fever (as with the flu). However, some forms of chronic inflammation can be harder to detect, requiring blood testing or imaging. Some inflammatory conditions need more specialized detection methods, while others can’t even be measured on commonly available tests.

Here are some conditions we now know are related to chronic inflammation:

  • Heart disease 
  • Diabetes
  • Asthma
  • Alzheimer’s disease
  • Rheumatoid arthritis 
  • Many types of cancer

 

We are always discovering new ways that inflammation contributes to many diseases.

What happens when inflammation affects the brain?

Inflammatory processes in the brain can affect how we think, act, feel, and move, often seemingly out of the blue.

For the purposes of the Unhide™ Project, we will define brain inflammation as a condition where cells from the immune system and/or their chemical products become abnormally active in areas of the brain and alter brain function.

Whether triggered by an infection or occurring as part of an autoimmune response (or both), brain inflammation can cause an eclectic mix of neurological and psychological symptoms and complications, from depression and anxiety to obsessive compulsive and movement disorders.

Using MRI (shown here), researchers examined how rheumatoid arthritis inflammation changes the brain.

In order to best treat these patients, doctors would ideally identify clues left by infection or an autoimmune response (like auto-antibodies directed at brain tissue). Unfortunately, sometimes it can be difficult to identify these triggers.

Pioneering Research in this Area

Autoimmune Diseases and Severe Infection as Risk Factors for Mood Disorders, a study published in JAMA Psychiatry in 2013, laid the groundwork to establish the connection between immune dysfunction and mental health. Researchers looked at over 91,000 Danish citizens diagnosed with a mood disorder (depression, bipolar disorder) and found that being hospitalized for an infection increased the risk of a later mood disorder by 62%.  A prior hospital contact due to an autoimmune disease increased the risk of a mood disorder by 45%.  They estimated that 12.1% of mood disorders would be prevented if the hospitalizations related to infections never happened.

The same team found that two or more severe infections in childhood, particularly where  hospitalizations were required, had increased risk of developing mental health issues including anorexia. The correlation of repeat infections and subsequent mood issues created an even greater risk than being diagnosed with an autoimmune disease. For instance, if a child is hospitalized for pneumonia, is treated and heals, but continues to relapse with two or more bacterial or viral infections into adulthood, they are at a greater risk of mood disorder in adulthood.

An inflammatory link between many central nervous system disorders and their mental health components has been recognized. These include lupus, Alzheimer’s, Parkinson’s, psoriasis, autism spectrum disorder, and multiple sclerosis (MS).

Since 2020, COVID-19’s ability to kill through cytokine storm and disable through lingering brain fog has focused the scientific community’s attention on the importance of unchecked inflammation. What we are learning is throwing open doors to understanding post-infectious brain inflammation. Yet there is still much we don’t understand.

With better understanding of brain inflammation, doctors, parents, and patients alike can more appropriately manage conditions that manifest with seemingly disparate symptoms, and which frequently appear following infection or other immune triggers.

Need for research: the Unhide™ Project

Our vision is for brain inflammation disorders to be easily diagnosed by medical professionals and to find accessible therapies. 

To support research in this area we developed the Unhide™ Project, a longitudinal and historical research registry and bio repository platform to study the potential immunological mechanisms driving chronic brain inflammation in order to find new therapeutic targets.

Research is critical to evolve current therapies and develop new treatment targets

The Unhide™ Project was established to collect lab samples from patients with diseases characterized by brain inflammation in order to compare and understand common biomarkers.
