Don’t sleep deprive yourself as it may be a precursor for major depression as you reach adulthood – occurring before other symptoms of major depression and additional mood disorders hit you hard.

A genetic study of adult twins and a community-based study of adolescents has reported novel links between sleep duration and depression.

Both short and excessively long sleep durations appear to activate genes related to depressive symptoms.

“We were surprised that the heritability of depressive symptoms in twins with very short sleep was nearly twice the heritability in twins sleeping normal amounts of time,” said Nathaniel Watson, associate professor of neurology and co-director of the University of Washington Medicine Sleep Centre in Seattle.

This new research emphasises that we can make an investment in our health by prioritising sleep, added M. Safwan Badr, president, American Academy of Sleep Medicine.

A study of 1,788 adult twins is the first to demonstrate a gene by environment interaction between self-reported habitual sleep duration and depressive symptoms.

Results suggest that sleep durations outside the normal range increase the genetic risk for depressive symptoms.

Among twins with a normal sleep duration of seven to 8.9 hours per night, the total heritability of depressive symptoms was 27 percent.

However, the genetic influence on depressive symptoms increased to 53 percent among twins with a short sleep duration of five hours per night and 49 percent among those who reported sleeping 10 hours per night.

Another study of 4,175 individuals between age 11 and 17 is the first to document reciprocal effects for major depression and short sleep duration among adolescents using prospective data.

Sleeping six hours or less per night increases the risk for major depression, which, in turn, increases the risk for decreased sleep among adolescents, said the study.

Optimising sleep may be one way to maximise the effectiveness of treatments for depression such as psychotherapy.

“Healthy sleep is a necessity for physical, mental and emotional well-being,” said Badr.

According to Robert E. Roberts, professor of behavioural sciences at University of Texas, “sleep disturbance and hours of sleep should be part of the medical history of adolescents to ascertain risk”.

The studies were published in the journal Sleep. (IANS)

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)
