A Pivotal Time.

Abstract

Neurodegenerative Diseases, founded two decades ago by Roger M. Nitsch and Christoph Hock [1], holds a crucial position in filling the gap between fundamental research and clinical applications. It is a great honor to succeed the esteemed founding editors and the accomplished former editor, Paul G. Unschuld, who have elevated the journal to its current level. The field of neurodegenerative diseases is currently experiencing a pivotal time. After the devastating COVID-19 killing countless older adults with neurodegenerative diseases and social isolation being imposed on older survivors, a new disabling condition known as long COVID has emerged, affecting the cognition of young and older adults. Besides the sad consequences of COVID-19, there is a recent hope with the revolutionizing disease-modifying therapies that are becoming available for patients with Alzheimer’s disease (AD). Interestingly, the founder editors of Neurodegenerative Diseasesmade a significant contribution to the development of diseasemodifying therapies for AD [2]. The SARS-CoV-2 pandemic had a worldwide impact (Fig. 1), destabilizing the healthcare systems and leaving a bitter taste as it neglected millions of older adults, particularly those with neurodegenerative diseases, even in the most developed countries, due to the lack of resources and knowledge. In April 2020, I remember evaluating at the Geneva University Hospitals’ ICU during a busy Friday evening a 75-year-old nuclear engineer with Parkinson’s disease, who was struggling with a severe SARS-CoV-2 infection. Remarkably, after 15 days of intubation, he was finally feeling better and able to breathe without respiratory assistance, allowing him the privilege to enjoy the Kiddush of Shabbat, the blessings performed at the beginning of the Friday evening Shabbat dinner; an unusual celebration for an ICU. Prepared with love by his wife, who was unfortunately prohibited from entering to the ICU for “safety” reasons, the patient was slowly eating and gave hope to his son, who stood by his father’s side, reciting together prayers welcoming the Shabbat. It was his last Shabbat. The religious man died 24 h later from a COVID-19 encephalopathy, one of the most devastating neurological complications of COVID19 [3]. On the next Monday, when I shared this sad news with my team, the young neuropsychologist, who had been diligently caring for the patient for 15 days, was totally devastated, falling into a deep burnout. Few months later, the same neuropsychologist experienced a mild SARS-CoV-2 infection but then suffered from a severe long COVID rendering her unable to care for her patients for several months. This story underscores how the pandemic has not only impacted patients and families but has also affected healthcare providers. Numerous reports have highlighted the alarming death rate among healthcare workers, either directly from SARS-CoV-2 infection [4] or from the indirect consequences of overwhelming pressure leading some to suicide [5]. Today, many questions remain unanswered regarding the consequences of COVID-19 on neurodegenerative diseases [6]: • Does the excess mortality among patients with neurodegenerative diseases stem from vulnerability of specific neurodegenerative conditions?
