COLDS AND RISK OF CEREBRAL ISCHEMIA IN CHILDREN
Here is the question that tried to answer a recent study, the results of which are published in Neurology’s journal of the American Academy of Neurology.  This new study found that the risk of stroke in children could be increased by colds and other minor infections, although temporarily.
Often associated with the elderly, everyone can have a stroke regardless of age. In France, ” the average age of a stroke is 73 years (70 years for men and 76 years for women). ”  . Stroke is one of the leading causes of childhood death in the United States, and according to the National Stroke Association, stroke affects about 6 people per 100,000 children. 
Minor infections and inflammatory conditions such as colds have already been associated with an increased risk of ischemic stroke in adults . Although the origins of pediatric stroke are slightly different, the effects of the common cold are the same for both (children and adults).
To the date, the association between inflammation and stroke in children has not been studied in depth. The research team, therefore, investigated in particular whether the timing and number of minor infections increased the arterial risk of the child – in the case of ischemic stroke ( TIA, transient ischemic attack).
According to the authors of the study, only a small number of children who are born with known risk factors for stroke – congenital heart disease, for example – may have an AIT, which leads them to speculate that the pediatric AIT has multiple etiological factors, including environmental factors such as exposure to minor infections.
Cold and risk of stroke in children
The researchers looked at data from the Kaiser Pediatric Stroke Study, a database that represents about 2.5 million children in a California healthcare organization (USA). 
From this review, the researchers identified 102 children who had an AIT without a severe associated infection and 306 children who had not had an AIT to serve as a control group. The medical records of these children were then studied for minor infections that occur up to 2 years before TIA. In the infections that were found, about 80% affected the airways.
The researchers found that the risk of stroke was increased, but only within 3 days between a visit to the doctor for signs of infection and TIA. Of the 102 children who had an AIT, 10 had a doctor’s visit for an infection within 3 days before TIA (9.8%). During the same period, only 2 children in the control group had an infection (0.7%). Thus, the authors calculate that children with TIA were 12 times more likely to have had an infection in the previous 3 days.
There is a need for further research. Many children may not have a quick visit to the doctor for a minor infection. The retrospective nature of the study also meant that the precise timing of infection initiation and drug use cannot be measured.
Dr. Heather Fullerton (pediatric neurologist), one of the authors of the study, said that their results suggest “that the infection has a large but short-lived effect on the risk of stroke.”. “We have seen this increase in the risk of stroke in adult infections, but so far no association has been studied in children. It is possible that inflammatory conditions contribute more to the risk of stroke in children, however, further research is needed to explore this possible association.”
Finally, the study states that ” minor infections are very common in children while strokes are fortunately very rare, and parents should not be alarmed if their child catches a simple cold.
