The grant, from the USA-based , a non-profit organisation that seeks to improve the lives of individuals living with autonomic nervous system disorders, has gone to Dr Jessica Eccles, National Institute for Health Research Clinical Lecturer at (BSMS), run by the universities of 麻豆果冻传媒 and Sussex.

Postural orthostatic tachycardia syndrome (POTS) is an under-studied disorder also characterised by tremors, heart palpitations and fainting or near-fainting upon moving from a prone to upright position.

The grant is aimed at further developing Dr Eccles’s research into the syndrome. She said: “Research suggests that almost all patients with POTS experience this disabling symptom – however, the mechanisms underpinning brain fog and its impact on quality of life are currently very poorly understood.

“With this grant from Dysautonomia International, I will seek to address this problem by understanding the brain-body mechanisms involved in brain fog.”

POTS mainly affects women (about 85 per cent of cases). Patients often experience thinking difficulties when the autonomic nervous system is challenged by being placed on a tilt table or standing, and there are also accompanying changes in blood flow in the brain. Dr. Eccles believes that brain fog may arise in a similar way, and hopes this project can further explore this area by combing such techniques with non-invasive imaging of the brain – use of an electroencephalogram and magnetic resonance imaging.

Dr Eccles explained: “Recent data from brain scans shows that challenging the autonomic nervous system in a similar way to standing changes blood flow in the brain in otherwise healthy individuals. Prior research demonstrates that POTS patients have altered blood flow to the brain when they stand. We think this may well be why patients with POTS experience brain fog.”

Dr Eccles hopes her research will help increase knowledge among patients and doctors alike: “We believe that this project will be relevant to finding and personalising treatments to individuals with POTS, brain fog and also patients with other conditions related to the autonomic nervous system. Potentially, this will bring relief from a considerably disabling symptom that has a significant impact on quality of life for patients living with these conditions.”

Lauren Stiles, President of Dysautonomia International, said: “Dysautonomia International is pleased to support the innovative POTS research occurring at BSMS, led by Dr Eccles. Gaining a better understanding of brain functioning in POTS may help us identify better treatment options for millions of people around the world living with POTS.”
