ABSTRACT
BACKGROUND: Medication-overuse headache (MOH) is caused by the regular use of medications to treat headache. There has been a lack of research into awareness of MOH. We distributed an electronic survey to undergraduate students and their contacts via social networking sites. Analgesic use, awareness of MOH, perceived change in behaviour following educational intervention about the risks of MOH and preferred terminology for MOH was evaluated. FINDINGS: 485 respondents completed the questionnaire (41% having received healthcare training). 77% were unaware of the possibility of MOH resulting from regular analgesic use for headache. Following education about MOH, 80% stated they would reduce analgesic consumption or seek medical advice. 83% indicated that over the counter analgesia should carry a warning of MOH. The preferred terminology for MOH was painkiller-induced headache. CONCLUSIONS: This study highlights the lack of awareness of MOH. Improved education about MOH and informative packaging of analgesics, highlighting the risks in preferred lay terminology (i.e., painkiller-induced headache), may reduce this iatrogenic morbidity and warrants further evaluation.

Cerebrospinal fluid is vital for normal brain function. Changes to the composition, flow, or pressure can cause a variety of neurological symptoms and signs. Equally, disorders of nervous tissue may alter cerebrospinal fluid characteristics. Analysis of cerebrospinal fluid can provide information on diagnosis, may be therapeutic in certain conditions, and allows a research opportunity into neurological disease. However, inappropriate sampling, inaccurate technique, and incomplete analysis can contribute to significant patient morbidity, and reduce the amount of accurate information obtained. In this article, we will review how cerebrospinal fluid is produced, circulated, and resorbed. We will also review lumbar puncture technique, equipment, and cerebrospinal fluid analysis. We also discuss how to minimize the risks and address the complications associated with lumbar puncture.
