Children who have experienced cognitive challenges show a loss of emotional dominance during the early phases of childhood a finding that may suggest miscarriages or other such problems in later childhood.

Research published in Biological Psychiatry found that children who had experienced cognitive challenges or difficulties in particular at birth defined as more severe than usual had fewer behavior and emotional control tasks during the next five years.

Memory and cognition are complex and multifunctional processes which can be impaired and impaired across childhood and adolescence. These deficits are not only evident in such cognitive difficulties but may also serve as early markers of other serious disorders of childhood such as anxiety disorders autism ADHD and schizophrenia noted principal investigator David Eagleman Ph. D. Memory and Affective Neuroscience a unit of Aarhus University.

It was indifferent where memory was impaired. One in five children had a lack of information followed by a lack of stimulation and then by cognitive deficits. The experiment proved to be successful the researchers say.

We observed some cognitive deficits in some of our own biological siblings. The reported results are without concern. It was interesting that the deficits were observed in two independent traits each each independent of even the same genes and environment. Besides these genes there was also a possible environmental factor for example genetic damage to brain holes in the brain nine-year-old Jane told a news conference at the Aarhus University.

She said that for each of the cognitive deficits the twins had shared behavioral and emotional problems at birth and then at nine years the extent of deficits began to diminish.

Patients suffering from emotion disorders or other disorders with similar deficits at nine years had significantly less activity in the brain areas that are important to memory and the ones that are implicated in thinking and memory.

We believe that these new ideas for diagnostic and diagnostic value may help to protect older siblings from neuropsychiatric disorders and cognitive challenges. Our strongly suggest that the diagnostic priorities should focus on memory problems in childhood adolescence and young adulthood the researchers say.

A limitation of the study was that the twins responses to behavioral and emotional control tasks differed from each other. Some tended to show normal response and for some it was impaired while for others it was normal.
