Panic attacks, marked by intense anxiety and physical symptoms, are linked to the activation of the sympathetic nervous system. The vagus nerve plays a key role in these responses, with techniques like the Valsalva maneuver helping regulate heart rate and blood pressure. Vergence therapy, which involves voluntary eye convergence, is being explored as a potential treatment. The oculo-cardiac reflex, known to influence heart rate, is also significant in this context.

Many children start school with undiagnosed vision issues, often mistaken for learning or behavioral disorders. Despite sporting new gear and having physical check-ups, a critical need often overlooked is a thorough eye exam. States like Kentucky, Missouri, and Illinois have enacted laws requiring compulsory eye exams before school entry. Vision involves more than 20/20 sight; it includes coordinated eye muscles and maintaining close-range focus. Over 57% of school-age kids have undiagnosed vision problems due to lack of thorough assessment. Screenings often miss many issues, raising concerns about their efficacy.

Research shows a link between weaker senses, such as bad eyesight and hearing, and a drop in thinking skills. More Americans are having trouble with their sight and hearing, especially older people. At the same time, more people are getting dementia. Studies suggest that not fixing these problems might speed up the loss of thinking skills. Making eyesight and hearing better could help improve these skills. Tech companies plan to make low-cost hearing aids. These could help keep the brain working well in older people. Experts advise regular eye and hearing tests. This could find problems early and may lower the chance of getting dementia.
