## Education

He was born in one of the most rural cities (Bandarawela), Uva Province (the poorest province in Sri Lanka, largely secondary to the ethnic genocide in 1815-1816. He attended a primary school that did not have high academic ambitions for the pupils.

## Research career

He was most inspired by the original work by his mentor Prof Nimal Senanayake as he continue to learn from his mentor from 1996 to 1999 as a lecturer in Medicine at the University of Peradeniya with ample exposure and clinical contribution towards the ongoing work of neurotoxicology under the leadership of Prof Nimal Senanayake at that time. As a result of his marriage to a medical graduate from Flinders University, Australia, he had to migrate to Australia at an early stage of his career. Wijeratne had to re-train in internal medicine and successfully completed his neurology advanced training in number of world class centres across New Zealand and Australia. He met Professor Robert Helme for the first time in late 2004 with an agreement to set up the stroke services as a rising star in neurology in 2004 at the Footscray Hospital, Western Health. This was the beginning of a remarkable research carrier of Wijeratne. On subsequent years he went on to work acute stroke care improvement with landmark contributions towards acute stroke therapies in collaboration with his research network across Australia and New Zealand.

## WFN Elected Trustee

Professor Tissa Wijeratne has been appointed as an elected Trustee of the World Federation of Neurology (WFN), making him the first Sri Lankan-born neurologist to hold this position. His involvement with the WFN began in 2005, contributing to neurology education, advocacy, and policy development. He has played a significant role in the World Brain Day (WBD) campaigns, an initiative launched in 2014 to raise awareness about neurological disorders. Under his leadership, WBD has expanded its reach, engaging stakeholders in over 100 countries. His election as a WFN Trustee acknowledges his contributions to global neurology and public health initiatives. Professor Wijeratne has also been nominated for the position of First Vice President of WFN. If elected, he aims to enhance neurology training, research, and preventive brain health programmes globally. His nomination marks a milestone for Sri Lanka and South Asia, reflecting the region's growing role in global neurology

## Research on Post-COVID-19 Neurological Syndrome

In 2025, Professor Tissa Wijeratne was recognized as the Field Leader in Neurology by The Australian Newspaper Annual Science Magazine. This recognition was based on his research contributions, including over 138 publications in the past five years on topics such as preventive brain health, stroke, migraine, and neurorehabilitation. His research has been widely cited, with a citation index of 135,000 and an H-index of 84, according to Google Scholar. His work has contributed to advancements in neurological research, policy, clinical practice, and education.

## Discovery of Post COVID-19 Neurological Syndrome

Professor Wijeratne and his research team were among the first to describe Post-COVID-19 Neurological Syndrome (PCNS), also known as Long COVID, and its underlying mechanisms. Their research identified the role of Serial Systemic Immune Inflammatory indices (SSIIi) in the progression of the condition during the early stages of the COVID-19 pandemic. Their work has influenced clinical management and ongoing research in post-viral neurological syndromes. His research group is among the most highly cited in Australia in the field of Long COVID and post-COVID-19 neurology.
Currently, Professor Wijeratne is editing a book on Post-COVID-19 Neurological Syndrome, invited by Springer Nature, which is expected to serve as a reference for researchers and clinicians working in the field.

## Contributions to Migraine and Headache Research in Australia

Professor Wijeratne has played a role in migraine and headache research and advocacy in Australia. He was mentored by Professors Peter Goadsby and Jim Lance and was involved in the establishment of the Australia New Zealand Headache Society in 2024. He contributed to drafting its constitution, designing its logo, and creating its website. He also produced a film on migraine and disability in Australia and was involved in establishing a dedicated charity for migraine in 2018. His research has highlighted the burden of migraine, including a 2018 Lancet publication that identified it as a leading cause of disability in Australia. In 2019, he led a World Brain Day campaign on migraine, contributing to a nationwide awareness effort. He was also involved in launching the HEAD research group, which studied headache-related admissions in emergency departments across Australia and New Zealand. This work led to the publication of 14 research papers.
Additionally, Professor Wijeratne and his colleagues proposed updates to the SNOOP-10 classification of secondary headaches, introducing two new headache syndromes and suggesting a revision to SNOOP-12 in 2023. He was appointed Section Editor for Stroke and Migraine in the Encyclopaedia 2023 Edition and has contributed to academic publications on migraine, headache disorders, and COVID-19-related brain involvement.

## Championing migraine/headache research in Australia

Wijeratne became a key catalyst for resurrecting headache research and advocacy in Australia. During this journey, Prof. Peter Goadsby and Prof Jim Lance mentored him. He became the key mastermind behind Australia's re-birth of headache society in 2024. Wijeratne wrote the original constitution, designed the logo and set up the first website template for the Australia New Zealand Headache Society. He produced the first-ever film on migraine and disability in Australia. His leadership was the key to establishing the first dedicated charity for migraine in 2018. Wijeratne and colleagues showed the world that migraine is the leading cause of disability in Australia in a landmark paper published in the Lancet in 2018. He then led the historic first-ever World Brain Day campaign on migraine with outstanding success. Wijeratne rallied the entire world towards a massive awareness campaign. On 22 July 2019, all ABC stations talked about migraines across Australia. Wijeratne and colleagues launched the HEAD research group at the same time. Over five thousand headache admissions across 67 Emergency Departments across Australia and New Zealand were studied in real-time with zero research funding support. 14 landmark research papers were published out of this work. Wijeratne et al went on introduce two new headache syndromes to the SNOOP-10 classification of secondary headaches with a proposal for SNOOP-12 during 2023 Wijeratne was appointed as the Section Editor for Stroke, Section Editor for Migraine and headache medicine, Encyclopaedia 2023 Edition in 2021. Advising to Science Direct, Wijeratne is Australia's leading academic publisher on migraine and headache disorders, COVID-19 and Brain Involvement, and Long COVID.

## World Migraine Day

Migraine Foundation launched the first ever World Migraine Day on 18 June 2023 with a resounding success with Five Million Steps campaign. Green colour theme was chosen by the hundreds of people with migraine as the green colour is most pleasing to the migraine impacted brain.
