In Memoriam: Prof. Regina Katzenschlager

We were deeply shocked and saddened to learn of the sudden passing of our dear friend and colleague, Prof. Regina Katzenschlager. She was a member of the MDS IEC until 2025 and contributed extensively across many areas of the MDS. Many members knew her as an expert in evidence-based medicine, having chaired the MDS Evidence-Based Medicine Committee from 2017 to 2021. She was also a member of the European Section’s Executive Committee from 2021 to 2025 and of the Movement Disorders Journal editorial board since 2022.

We knew her not only as an excellent neurologist and movement disorder expert with extensive exceptional expertise, but also as someone who was eager to learn every detail about Parkinson’s disease, especially its treatment. She was a pioneer in invasive treatments, including apomorphine pump treatment, and was first author of the landmark TOLEDO Study. She never rested until challenges in clinical trials or publications were resolved.

Originally from Vienna, Austria, Regina trained in London under Andrew Lees, whom she greatly admired and was always delighted to meet. Regina became an internationally recognized expert in Parkinson’s disease, holding numerous official roles in scientific societies. She was active in both the MDS and the EAN, regularly presenting at international congresses. She served as the current president of the Austrian Parkinson’s Society, where she was a leading figure in PD research and clinical care. She was also active in education, contributing significantly to neurologists’ training strategies and serving on the Austrian neurology examination committee.

As a researcher, she published more than 120 papers on Parkinson's disease treatment, including advanced treatments and pharmacological issues. She always valued patients’ perspectives while maintaining the highest scientific standards.

Regina had a warm, friendly, and gracious personality. She was always willing to support others, especially her female colleagues, and was a role model and mentor to many women within the MDS. In addition to her diligent advice, we will remember her warm and lively laughter. She was such a good friend, always there for us in difficult situations, as well as for celebrating success and enjoying life!

Those who knew her personally experienced her sincere care for her family, especially her beloved son, who travelled with her to many countries. We still can’t believe that this wonderful person’s life has ended.

Now, let's hear from some more female colleagues, who knew her:

Regina was a brilliant mind, whose wisdom extended far beyond professional matters. I remember her saying that whatever happens at work, what matters most is having someone with whom you can share it when you come home. I have carried that thought with me ever since.”

Regina was a wonderful colleague and friend, with spirit and grace. You are missed!”
