![]() ![]() If severe and frequent migraines are a problem, your doctor may prescribe a “rescue” medication to treat pain and help stop the migraine after it has started. Try to limit use to less than 3 times per week in order to avoid rebound headaches. But taking pain relievers too often can actually cause more headaches, called medication overuse headaches or “rebound” headaches. If your migraine symptoms are not frequent, you may be able to treat them with over-the-counter (OTC) pain-relievers. Some people have visual auras but no headache, which is known as ocular migraine. Migraine with aura occurs in 25% to 30% of people with migraines. You may notice visual symptoms just before or during a migraine headache and are known as visual auras. Migraine causes severe headaches that usually last from 4 to 72 hours, and people often have other symptoms like nausea and light or sound sensitivity. Visual symptoms: bright or colorful spots, sparkles or shimmering lights, zigzagging lines, or stars.There are different types of surgeries, but the goal is to stabilize the retina if you have a retinal tear or detachment. However, if you have ongoing problems with vision and it is affecting your quality of life, you may want to consider surgery. Symptoms of floaters can get better with time as the gel-like pieces settle to the bottom of the eye. This can also increase risk of retinal detachment. When it tugs at the retina, it can cause flashes of bright light. The parts of the gel that move around the eye when this occurs can cause floaters. When this occurs, it can pull on and separate from the retina at the back of the eye. ![]() It is caused by the gel-like substance in the eyes (known as vitreous) partially liquifying and shrinking with age. It starts happening between the ages of 50 and 70. Posterior vitreous detachment (PVD) is the most common cause of floaters and flashing lights. Floaters are more noticeable when looking at a plain light-colored background in bright light.Flashes of light (can look like lightning or camera flashes).Floating dark spots (can look like strings or cobwebs).The research goes so far as to say that the activity could support the idea of a last “recall of life” that takes place in a near-death state.Causes 1. Scientists found that the type of brain activity occurring in the man’s brain was similar to that experienced when someone recalls something from memory. While it might seem surprising, the scientists believe that this is the first time brain activity in a human being was recorded during death.

The fascinating findings were discovered thanks to an 87-year-old man who wound up in the emergency room after experiencing a fall. The study was published in the journal Frontiers in Aging Neuroscience and was conducted by a team of scientists from around the world, including members of the neurosurgery department at UBC and the neurosurgery division of the department of surgery at U of T. A new study has revealed the inner workings of the brain upon death, and it reveals that significant brain activity takes place during that period of time. ![]()
