Is Intracranial Hypotension Responsible for Headache After LP?

Lumbar puncture is an important part of any neurologist’s toolkit. But patients who need an evaluation of their CSF are already struggling with symptoms of some kind that necessitated the procedure. No one wants to add to their discomfort. This is why understanding the etiology of post-dural puncture headache (PDPH) is so important to the field of neurology. PDPH, which occurs in 32 percent of cases, can last for days and may be incapacitating. This makes understanding the cause important for obtaining the best diagnostic information while avoiding morbidity. Young adults and females are at greatest risk for PDPH as are those with lower body mass or undergoing procedures with larger needles or multiple punctures. According to the International Classification of Headache Diagnoses, 3 rd Edition (ICHD-3), PDPH is a subcategory of ICHD 7.2: “Headache attributed to low cerebrospinal fluid pressure.” It can only be diagnosed if it occurs within five days of the procedure with document...

Are you confident that your staff would give you the best quality study for your family member? And if you can’t say absolutely , then your staff is not trained well enough.” Kubiak is the current president of ASET the Neurodiagnostic Society and her group is lobbying hard to make sure the most qualified professionals are the one’s performing EEG studies. “There should not be people monitoring your epilepsy patients who are not credentialed and who do not have at least three to five years of experience,” she said in a recent phone interview. Physicians may or may not realize just how unregulated the field of neurodiagnostic technology is. Currently there is no state that requires EEG techs to have any formal education, or to be li...
