The recent study suggests that kids who see flashing light during migraine have more than double the normal probability of having hole in the heart. In a study carried out a team of US doctors, examined more than one hundred kids aged over six and who were suffering migraine.
It was found that at least half of those having a type of migraine along with a visual disturbance known as an aura had heart flaw. Several medicinal studies have discovered a connection between a hole-in-the-heart that is technically called as a patent foramen ovale (PFO) and migraine with aura in adults.
A flap or valve-like opening in the wall situated between the two upper chambers of the heart. It is often found before birth, but seals shut in about eight percent of people. When occurred pressure inside the chest, for example by coughing, the flap can open, allowing blood to flow in either direction.
This can allow blood to bypass the filtering system of the lungs. If wreckage is present in the blood like tiny blood clots, it can traverse the left atrium and lodge in the brain that causes a stroke. This had escorted to endeavors to cure migraine by surgery to close the hole, when other migraine therapies have unsuccessful.
About one in ten people have aura with their migraines. Common aura symptoms include visual disturbances like seeing flashing or flickering lights, lack of sensation, tingling sensations and slurred speech. According to Amy Thompson, senior cardiac nurse from the British Heart Foundation, there could be a number of explanations for this connection so further research is required before drawing any firm conclusions.
Once the connection is understood in more detail, it could signal an upgrading in care of the patients, added Thompson. A scanning technique known as an echocardiogram to look for the heart defect is used by Dr Rachel McCandless and team from the University of Utah, of kids who had migraine with aura, fifty percent also had heart defect.
This is almost twice the rate seen in the common people. She hoped that their study will help in guiding future study about this difficult problem, added McCandless.
