Minor infections, such as a mild case of sniffles, can cause negative effects on a person’s intellect. A new study reveals that infections and associated immune responses are capable of causing a damaging effect on the IQ on the patient. However, early signs of minor infections, such as a bout of sinusitis, are not capable of lowering a person’s IQ, for it takes much more severe infections.
Researchers attempted to study these claims with a series of cognitive ability tests conducted amongst a sample group of people who had suffered infections and were hospitalized. The results revealed that the patients who were hospitalized scored 1.76 units less on a cognitive ability test as opposed to those who weren’t hospitalized to cure the infection.
Moreover, the patient’s IQ dropped as the number of instances he/she was hospitalized increased. For instance, those who had been hospitalized 10 times or more scored 5.54 unites less as compared to the healthier participants. The researchers concluded that our body’s immune response to the infection, particularly inflammation, can cause a reduction in our brainpower, which alters the pattern of cell communication within the brain.
3. Lyme Disease
Lyme disease is gravely dangerous disease that requires you to make effective use of a bug spray and nicely tuck in your socks to protect your body and your IQ before you go hiking, trekking or running in the wild. The most common symptoms of Lyme disease include aching joints, muscle pain, weariness, fatigue and impaired brain functioning.
Researchers believe that Lyme disease can cause severe brain impairments, a sharp decline in the functioning of brain processes, memory problems, lack of concentration, a shortened attention span and an inability to perform multitasking.
Experts point out that these impairments occur because of the increased pressure suffered by the head, which also causes the severe headaches that most patients suffering with Lyme disease complain of. Moreover, this disease also reduces and limits the blood flow received by the brain, hence depriving the brain of sufficient oxygen levels required for optimal functioning.
