The disorder is characterized by intractable early\u2010onset seizures, severe neurodevelopmental delay, hypotonia, motor disabilities, cerebral (cortical) visual impairment and microcephaly. With no disease\u2010modifying therapies available for CDD, treatment is symptomatic with an initial focus on seizure control. Another unmet need in the management of people with CDD is the lack of evidence to aid standardized care and guideline development. To address this gap, experts in CDD and representatives from patient advocacy groups from Denmark, Finland, France, Germany, Italy, Poland, Spain, and the United Kingdom convened to form an Expert Working Group. The aim was to provide an expert opinion consensus on how to ensure quality care in routine clinical practice within the European setting, including in settings with limited experience or resources for multidisciplinary care of CDD and other developmental and epileptic encephalopathies. By means of one\u2010to\u2010one interviews around the current treatment landscape in CDD, insights from the Expert Working Group were collated and developed into a Europe\u2010specific patient journey for individuals with CDD, which was later validated by the group. Further discussions followed to gain consensus of opinions on challenges and potential solutions for achieving quality care in this setting. The panel recognized the benefit of early genetic testing, a holistic personalized approach to seizure control (taking into consideration various factors such as concomitant medications and comorbidities), and age\u2010 and comorbidity\u2010dependent multidisciplinary care for optimizing patient outcomes and quality of life. However, their insights and experiences also highlighted much disparity in management approaches and resources across different European countries. Development of standardized European recommendations is required to align realistic diagnostic criteria, treatment goals, and management approaches that can be adapted for different settings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Plain language summary<\/jats:title><jats:p>Cyclin\u2010dependent kinase\u2010like 5 (CDKL5) deficiency disorder (CDD) is a rare condition caused by a genetic mutation with a broad range of symptoms apparent from early childhood, including epileptic seizures that do not respond to medication and severe delays in development. Due to the lack of guidance on managing CDD, international experts and patient advocates discussed best practices in the care of people with CDD in Europe. The panel agreed that early testing, a personalized approach to managing seizures,\u00a0and access to care from different disciplines are beneficial. Development of guidelines to ensure that care is standardized would also be valuable.<\/jats:p><\/jats:sec>","DOI":"10.1002\/epi4.12914","type":"journal-article","created":{"date-parts":[[2024,3,7]],"date-time":"2024-03-07T12:52:15Z","timestamp":1709815935000},"page":"832-849","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Providing quality care for people with <scp>CDKL5<\/scp> deficiency disorder: A European expert panel opinion on the patient journey"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2688-2529","authenticated-orcid":false,"given":"Sam","family":"Amin","sequence":"first","affiliation":[{"name":"University Hospitals Bristol  Bristol UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9664-1448","authenticated-orcid":false,"given":"Rikke S.","family":"M\u00f8ller","sequence":"additional","affiliation":[{"name":"The Danish Epilepsy Centre, Filadelfia  Dianalund Denmark"},{"name":"Department of Regional Health Research, Faculty of Health Sciences University of Southern Denmark  Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4889-3365","authenticated-orcid":false,"given":"Angel","family":"Aledo\u2010Serrano","sequence":"additional","affiliation":[{"name":"Vithas Madrid La Milagrosa University Hospital Vithas Hospital Group  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7233-2771","authenticated-orcid":false,"given":"Alexis","family":"Arzimanoglou","sequence":"additional","affiliation":[{"name":"San Juan de Dios Children's Hospital  Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Bager","sequence":"additional","affiliation":[{"name":"CDKL5 Deutschland e.V.
