Problems during childbirth and complications affecting a pregnancy can lead to damage, connected to the brain, once these babies become children. [Pregnancy Complications]
A study, carried out in the nineties by the Southmead Hospital in Bristol showed, over a fifty percent likelihood of a lower IQ in children resuscitated after birth, although at the time no further treatment was required.
At the age of eight the effects seemed to manifest themselves.
The research known as the Children of the 90s study, also showed that infections contracted by pregnant women were also a contributory factor in regard to IQ levels. The definition of a low IQ was deemed as being below eighty for this research.
Commenting on the findings Andy Cole, the spokesperson for the charity Bliss noted that in the last decade certain practices had been greatly improved upon including the methods of actual resuscitation. So in some respects technology has made some of the finding redundant.
Hypoxia at birth, where the baby is starved of oxygen for a significant length of time, was also seen to be another reason for lower IQs found in children. Overall the data proves that there needs to be a more succinct way of determining how much actual damage has been done at this time.
All the result were published recently in the Lancet, and also seem to suggest that cognition could be affected in later life as well as in childhood. Damage to the subtle neuronal or synaptic nerves is the known reason for this.
