Patients with a history of migraine have a heightened risk of perioperative ischaemic stroke, according to new research published in The BMJ. In a prospective hospital-based registry study, migraine was associated with a 1.75-fold increase in the incidence of stroke within 30 days of surgery, and the risk was particularly high in patients who had...
Pain development and discomfort are universal features of spider envenomation, yet severe pain arising from bites by Old World spiders is poorly understood. Molecular analyses of the venom of the King Baboon spider revealed abundant expression of the inhibitory cystine knot peptide Pm1a. Synthetic Pm1a induces pain in mice while simultaneously...
New research shows that men in their 20s and 30s have worse survival from many different types of brain tumors than women of the same age. And, researchers say, it's not exactly clear why.
Several studies have reported alterations in gut microbiota composition of Alzheimer's disease (AD) patients. However, the observed differences are not consistent across studies. In a new study the investigators aimed to investigate associations between gut microbiota composition and AD biomarkers using machine learning models in patients with AD...
In a new study (BMJ 2022;376:e068005) multimorbidity, particularly when onset is in midlife rather than late life, has a robust association with subsequent dementia.
Dairy intake may increase risk of Parkinson's disease in men, according a group of investigators. Men of European ancestry with a genetic marker predicting dairy consumption had significantly greater risk of Parkinson's disease than individuals without the marker, suggesting a causal relationship between dairy intake and Parkinson's disease, author...
Young adults performed worse on memory and attention tests several months after an acute case of mild COVID-19, according to a small study that may support the "brain fog" reported by many.
Brains of COVID-19 patients had some of the same pathological changes seen in Alzheimer's disease, which may explain the memory problems people with long COVID experience, a small study suggested.
Dementia incidence tripled in lonely older adults who otherwise would be expected to have relatively low risk based on age and genes, researchers found in a recent study.
In a new study published in Neurology the objective was to examine the association between occupational exposure to formaldehyde and cognitive impairment in middle-aged and young-old adults (≥45 years).
