BackgroundPost-dural puncture headache (PDPH) is still mostly regarded a minor complication after lumbar puncture. In the International Classification of Headache Disorders (ICHD)-3 headaches lasting longer than 14 days or persisting after epidural blood patch (EBP) are not even considered. We illustrate that there may be many patients with persisting headaches and a large disease burden.MethodsIn a retrospective, single center analysis from 04/2018 to 03/2022 we assessed patients with a dural puncture and orthostatic headache of >14 days duration, resistant to one or more EBPs. Socioeconomic factors and individual patient history were assessed by a specifically designed questionnaire.ResultsWe included 30 patients with a mean age of 36.4 (±10.6) years. The median duration of acute inpatient care was 31 (Interquartile ratio (IQR) = 32) days and of sick leave 381 (IQR = 666.3) days. Patients consulted a median of 5 (IQR = 6.5) different physicians/ institutions due to chronic post-dural puncture headache (cPDPH). All patients reported major negative impact of cPDPH on their social and work life.ConclusionDespite long hospitalizations and a profound impairment of social and work lives cPDPH was neglected and underrated in all patients. We conclude that cPDPH needs to be considered and might be an underreported, severe condition which requires further prospective studies.

IntroductionPatients with spontaneous intracranial hypotension (SIH) frequently present with several symptoms and impaired mental health. This study systematically investigates the somatic and mental symptom burden of SIH and the effect of surgical treatment.MethodsIn this single-center retrospective study, patients with surgical closure of a spinal cerebrospinal fluid leak between September 2022 and July 2023 completed the Somatic Symptom Scale (SSS-8), the Somatic Symptom Disorder – B Criteria Scale (SSD-12), and the Patient Health Questionnaire (PHQ-8) preoperatively and three and 6 months postoperatively.ResultsFifty-seven patients were included. All three scores showed clearly pathological values before surgery (SSS-8: 12 [IQR 6.5–16], SSD-12: 26 [IQR 19.5–33.5], PHQ-8: 11 [IQR 6.5–15]) representing a high somatic symptom burden and relevant current depression. After surgery, there was a significant and sustainable improvement (SSS-8: 8 [IQR 3–11.75], SSD-12: 12.5 [IQR 5–21.75], PHQ-8: 4.5 [IQR 2–9], p

The identification of pathological atrophy in MRI scans requires specialized training, which is scarce outside dedicated centers. We sought to investigate the clinical usefulness of computer-generated representations of local grey matter (GM) loss or increased volume of cerebral fluids (CSF) as normalized deviations (z-scores) from healthy aging to either aid human visual readings or directly detect pathological atrophy.Two experienced neuroradiologists rated atrophy in 30 patients with Alzheimer's disease (AD), 30 patients with frontotemporal dementia (FTD), 30 with dementia due to Lewy-body disease (LBD) and 30 healthy controls (HC) on a three-point scale in 10 anatomical regions as reference gold standard. Seven raters, varying in their experience with MRI diagnostics rated all cases on the same scale once with and once without computer-generated volume deviation maps that were overlaid on anatomical slices. In addition, we investigated the predictive value of the computer generated deviation maps on their own for the detection of atrophy as identified by the gold standard raters.Inter and intra-rater agreements of the two gold standard raters were substantial (Cohen's kappa κ > 0.62). The intra-rater agreement of the other raters ranged from fair (κ = 0.37) to substantial (κ = 0.72) and improved on average by 0.13 (0.57
