Or the sign, which we do not link with stroke because it can be resolved very quickly.
A stroke occurs when a blood clot obstructs an artery or blood vessel tears apart and interrupts blood flow to the brain. Brain cells need constant supply of oxygen, carried to them by blood, so they can function normally. If the blood flow to the brain is disrupted due to clogging, this will result in the death of cells in a part of the brain, where a clogged artery can no longer supply the oxygen. This leads to the development of characteristic signs and symptoms that can last for several weeks, months or even forever. Each year, more than 5 million people in the world, die due to stroke.
Strokes can cause many different symptoms (most of them develop in a few seconds), including slurred speech, difficulty in walking, weakness and difficulty in understanding. However, what may also occur is one of the less known symptoms – unilateral visual disturbances (hemianopsia). In this case, you suffer from loss of vision in half of the vision field on one eye or both eyes. For example, if you watch the “STOP” sign, you may only see the letters O and P, while the letters S and T remain invisible.
This phenomenon can only take a few minutes before the restoration of the normal vision, but it is a sign that the visual cortex in the back of the brain was affected due to loss of blood flow. CT and MRI imaging can reveal the part of the brain responsible for vision that experienced stoppage of the blood flow. In such form you can experience small strokes, which can often lead to a stronger stroke.
According to the research, the risk of stroke is reduced with a diet full of fruits, vegetables and white meat. In addition, taking two aspirins in a lower dose (81 mg) once daily at bedtime decreases the possibility of blood clots. Of course, before doing so, it is important you consult your doctor.
