Cognitive Effects of Radiation
There have been many terrible consequences of the Chernobyl accident, the worst of which has been the suffering and death of millions of Ukrainian people due to radiation exposure. The Physical deterioration of the residents exposed to high amounts of radiation has been extensive and severe, with the rates of cancer and other diseasesshooting up by the hundreds of percents. Out of the 100,000 citizens relocated from the Chernobyl plant and the city of Pypiat, Heart and Blood disease has gone up 938% from .74/1000 to 6.94/1000, Endocrine, Digestive and Immunity disease has risen 1350% from 12.67/1000 to 171.11/1000, Respiratory disease has risen 577% from 23.67/1000 to 138.68/1000, and Nervous System disease has risen 500% from 21.25/1000 to 106.28/1000. Other diseases, such as thyroid cancer and birth defects in children, have also risen in sharp increments. One of the most unexplored regions of radiation exposure has been the threat and consequence of cognitive decrements. There has been proven to be many negative factors associated with exposure to radiation, such as fatigue, memory loss and memory retention problems, concentration loss, lack of mental flexibility, stimulus response
Loss of concentration and high confusability are also symptoms associated with radiation exposure, yet it is still uncertain whether or not this is caused directly from the exposure to radioactive substances, or if it is a symptom of the high rate of fatigueability that is shown to be common in victims of radiation. On the Stanford Sleep Scale, a test created to determine the exhaustion level of patients undergoing mental testing, radiation victims have, on the average, shown a drop of at least1 level after being tested for a period of 45 minutes, a fatigue rate that is much higher than normal. Their loss of concentration and mental confusion has also been demonstrated by the Running Memory test, which repeats a series of sixty letters, and asks the respondent to identify whether or not the previous letter is the same as the one being presently shown. People who have been exposed to radiation, depending upon the dosage received, often have trouble performing this task, and quickly become confused. Mental flexibility is also a problem with people who have been exposed to large doses of radiation. They have a difficult time with spatial rotation, which is the ability to imagine an object in your mind and turn it around to different angles and degrees. If shown two objects, one being a symbol and the other being the symbol at a 90-degree angle, a person with radiation exposure would have a more troublesome time than a normal person in recognizing it as a matching symbol. It has also been found through testing that rotating an object and reversing an object as a mirror does can produce different results, showing that both tests activate different structural areas of the brain.
