Purpose Of Review: We define dehydration and its relationship to pain physiology including both primary and secondary headache disorders.
Recent Findings: Intravenous fluids administered for acute migraine attacks in an emergency department setting have not been shown to improve pain outcomes. However, increased intravascular volume before diagnostic lumbar puncture may reduce the frequency of post-lumbar puncture headache from iatrogenic spinal fluid leak. Maintenance of euhydration can help treat orthostatic and "coat-hanger" headache due to autonomic disorders. Similarly, prevention of fluid losses can mitigate secondary headaches provoked by dehydration such as cerebral venous thrombosis or pituitary apoplexy. Dehydration alone may cause headache, but oftentimes exacerbates underlying medical conditions such as primary headache disorders or other conditions dependent on fluid balance.

Cerebral venous sinus thrombosis (CVST) is the causative factor in a small proportion of strokes. It primarily affects individuals aged less than 55 years, with up to two-thirds of cases affecting females. It can be precipitated by a myriad of transient or permanent risk factors that result in a prothrombotic state.

Background: In children and adults with sickle-cell disease (SCD), acute ischemic stroke (AIS) associated with a vaso-occlusive crisis is a leading cause of physical and cognitive disability and death. However, neurological guidelines for acute management of AIS fail to directly address this issue. We here report a case of a man with severe cerebrovascular complications and illustrate the current evidence on the management of SCD-related AIS.

Article Synopsis
- The study investigated the occurrence and risk factors of adverse events (AEs) related to intravenous immunoglobulin (IVIG) therapy in hospitalized children under 18 years old.
- A total of 228 patients were reviewed, resulting in 478 IVIG treatments, with mild reactions like fever and headache being the most common, although some reactions were severe.
- Key predictors of IVIG-AEs included older age, dehydration, allergies, being on the first treatment, and receiving higher doses, while concurrent steroid use seemed to reduce risk.

Hangovers from alcohol consumption cause symptoms like headaches, nausea, and fatigue, disrupting daily activities and overall well-being. Over time, they can also lead to inflammation and oxidative stress. Effective hangover relief alleviates symptoms, prevents dehydration, and replenishes energy needed for daily tasks.
