Depression in Parents Responsible for Brain Differences of Kids

Researchers have found structural differences in the brains of children at high risk for depression due to parental depressive history.

Depression is a common and debilitating mental health condition that typically arises during adolescence. While the causes of depression are complex, having a parent with depression is one of the biggest known risk factors.

Studies have consistently shown that adolescent children of parents with depression are two to three times more likely to develop depression than those with no parental history of depression.

“The findings highlight a potential risk factor that may lead to the development of depressive disorders during a peak period of onset, said study author Randy P. Auerbach, Associate Professor at Columbia University in the US.

“However, in our prior research, smaller putamen volumes also has been linked to anhedonia–a reduced ability to experience pleasure–which is implicated in depression, substance use, psychosis, and suicidal behaviours,” Auerbach said.

“Thus, it may be that smaller putamen volume is a transdiagnostic risk factor that may confer vulnerability to broad-based mental disorders,” Auerbach added.

For the study, published in the Journal of the American Academy of Child & Adolescent Psychiatry, the researchers analysed brain images from over 7,000 children in the United States participating in the Adolescent Brain Cognitive development (ABCD) study, led by the National Institutes of Health (NIH).

According to the study, about one-third of the children were in the high-risk group because they had a parent with depression.

The research found that in the high-risk children, the right putamen–a brain structure linked to reward, motivation, and the experience of pleasure–was smaller than in children with no parental history of depression.

“Understanding differences in the brains of children with familial risk factors for depression may help to improve early identification of those at greatest risk for developing depression themselves, and lead to improved diagnosis and treatment,” said study researcher David Pagliaccio. (IANS)

Children of Mothers With Diabetes Are Likely To Suffer From Heart Diseases, Says Study

The researchers also found higher rates for specific types of CVD children of mothers with diabetes

Children of mothers with diabetes have increased rates of early onset cardiovascular disease or CVD (conditions affecting the heart or blood vessels) from childhood up to the age of 40, the researchers have warned.

The increased rates were more pronounced among children of mothers with a history of CVD or diabetic complications, said the study published in the journal The BMJ.

“Our study provides evidence that children of mothers with diabetes, especially those with a history of CVD or with diabetic complications, had increased rates of early onset CVD throughout the early decades of life,” said study researchers from Aarhus University in Denmark.

If this association is shown to be causal, preventing, screening, and treating diabetes in women of childbearing age could be important not only for improving the health of the women but also for reducing long term risks of CVD in their offspring, the researchers added

The number of women diagnosed with diabetes before or during pregnancy has increased globally, and children of these women are more likely to have risk factors for future CVD, such as high blood pressure and high blood sugar levels. It is unclear, however, whether or to what extent exposure to diabetes in the womb increases the risk of developing CVD in offspring over a lifetime.

So an international team of researchers set out to evaluate associations between diabetes diagnosed before or during pregnancy and early onset CVD in children during their first four decades of life. They base their findings on national registry data for over 2.4 million children born without congenital heart disease in Denmark from 1977 to 2016.

Diabetes was categorised as pregestational (before pregnancy) or gestational (during pregnancy) and women with diabetic complications were identified.

Other potentially influential factors, such as mother’s age, education, lifestyle and medical history were also taken into account. During up to 40 years of follow-up, children of mothers with diabetes had a 29 per cent increased overall rate of early onset CVD compared with children of mothers who did not have diabetes (cumulative risks: 17.8 per cent vs 13.1 per cent ).

The researchers also found higher rates for specific types of CVD children of mothers with diabetes, particularly heart failure (45 per cent), hypertensive disease (78 per cent), deep vein thrombosis (82 per cent), and pulmonary embolism (91 per cent).

Increased rates were seen in each age group in childhood (before 20 years of age) and early adulthood (from 20 to 40 years of age), regardless of the type of diabetes they were exposed to (pregestational or gestational) and rates were similar for both type 1 and type 2 diabetes, the study said.
