BIOMARKAPD seeks to diminish the barriers associated with the clinical use of cerebrospinal fluid (CSF) biomarker analysis by reducing variation in CSF laboratory methodologies and generating consensus recommendations on their clinical interpretation and application for dementia diagnosis. To examine the disparity in practitioner attitudes and clinical practice relating to the use of CSF biomarkers for dementia diagnosis across Europe. Clinical dementia experts were surveyed on the prevalence of national consensus guidelines and analytical reimbursement across Europe; their biomarker platform preferences, lumbar puncture methodologies, and application of reference values and cut-offs for CSF analysis. 74% of respondents (total n = 51) use CSF biomarkers in clinical practice and 69% performed lumbar punctures on an outpatient basis. Most use CSF biomarkers to diagnose atypical (84%) and early onset cases of cognitive impairment (71%) and for the differential diagnosis of other dementias (69%). 82% state they are sufficiently informed about CSF biomarkers yet 61% report a lack of national consensus guidelines on their use for dementia diagnosis. 48% of countries represented do not reimburse clinical CSF analysis. 43% report using normal reference ranges derived from publications. Variations in attitude and practice relating to CSF biomarkers, widely recognized as barriers to their clinical acceptance, remain evident within and between countries across Europe, even in expert centers. These shortcomings must be addressed by developing consensus guidelines on CSF-related methodologies and their clinical application to further their use for the diagnostic evaluation of dementia.
