Eligible participants were healthy controls, premanifest and manifest gene expansion carriers. We investigate the odds of any adverse events, headaches, and back pain independently. Intergroup comparisons and adjusted event odds were derived using hierarchical logistic regressions.Results A total of 684 LP involving 500 study participants were included in this analysis (139 healthy controls, 179 premanifest HD, 182 manifest HD). The detailed results of our analysis will be presented at the European HD Network meeting.Conclusions The LP is safe in patients with HD.}, issn = {0022-3050}, URL = {https://jnnp.bmj.com/content/92/Suppl_1/A24.2}, eprint = {https://jnnp.bmj.com/content/92/Suppl_1/A24.2.full.pdf}, journal = {Journal of Neurology, Neurosurgery \& Psychiatry} }
