The most frequent symptoms reported were imbalance and vertigo, and the duration of attacks varied. Treatment regimens included aspirin, clopidogrel, aspirin plus clopidogrel, and rivaroxaban, and the attacks were reduced by 93.2% during the median follow-up of 12 months. The study concluded that secondary stroke prevention is effective in VVD due to VBTIA, although no prognostic factors for symptom recurrence could be identified. [Extracted from the article]

A recent preprint study explores the role of the Ten-Eleven Translocation (TET) family of dioxygenases in the development of photoreceptor cells in the retina. The researchers found that genetic ablation of the TET family prevents the demethylation of genes essential for rod and cone maturation, leading to underdeveloped photoreceptors and impaired vision. The study suggests that the loss of function in these photoreceptors eventually leads to blindness. However, it is important to note that this research has not yet undergone peer review.

A recent study conducted at the Japanese Red Cross Shizuoka Hospital explored the relationship between migraine-associated features and their impact on headache intensity, pain levels, and psychiatric conditions in patients with migraine. The study found that symptoms such as nausea, vomiting, photophobia, phonophobia, and allodynia were independent predictors of higher headache impact and pain intensity scores. Additionally, nausea, phonophobia, and allodynia were associated with higher scores on the Generalized Anxiety Disorder 7-item scale, while vomiting was a negative predictor of scores on the Patient Health Questionnaire-9. These findings highlight the importance of understanding the distinct effects of these features in order to personalize the management of patients with migraine. [Extracted from the article]

A report from the Chinese Academy of Sciences explores the neural mechanisms underlying placebo and nocebo effects in tonic muscle pain. The study used a 15-minute tonic muscle pain induction procedure on healthy participants and collected real-time pain ratings and functional magnetic resonance imaging (fMRI) data.
