Brain’s memory area might be associated with anxiety and depression

Addiction, for example, could be linked to deficits of approach motivation. Anxiety and depression on the other hand could be linked to avoidance behaviours

An area of the brain, commonly linked with memory and dementia, could also yield important clues about a range of mental health illnesses including addiction, anxiety and depression, a study has found.

The area, known as hippocampus, is a seahorse-shaped structure located deep inside the brain. As part of the limbic system, it plays an important role in memory processing and spatial cognition, including how mammals learn to understand and navigate their environment. Hippocampus have been long known for its role in memory and dementia, especially in relation to Alzheimer’s disease. In Alzheimer’s patients for instance, this region is one of the first areas of the brain to suffer damage.

The study, published in the journal Current Biology, revealed that because hippocampus plays a role in basic motivational behaviour, it may also offer important insights into a range of mental health illnesses. Addiction, for example, could be linked to deficits of approach motivation. Anxiety and depression on the other hand could be linked to avoidance behaviours, all of which could manifest itself in this part of the brain, Ito said.

“Some patients have lesions to certain areas of this part of the brain, so hopefully we can assess them to see what particular aspects of approach avoidance behaviour may or may not be impacted,” the researchers said. IANS

Depression in Children Stay Undetected by Parents and Teachers- Study

The gold standard for identifying children who might be at risk for developing depression later in life is to ask the children themselves

Parents and teachers may find it difficult to detect depression in young children, that can affect their social skills and academics, a new study shows.

According to Anxiety and Depression Association of America, as many as 2-3 per cent of children aged between 6-12 might have a major depressive disorder.

But parents and teachers face difficulties in recognising depression in children.

The findings, appearing in the Journal of School Psychology, showed that children who show mild to severe symptoms of depression in second and third grades are six times more likely to have skill deficits, such as difficulties with social skills or academics, than children without symptoms.

However, when teachers and parents were asked to rate a child’s level of depression, there was only about 5-10 per cent overlap in their ratings.

“Some people would view that overlap as the truth about a child’s well-being and areas of disagreement as errors, but we need to explore the possibility that each of them are seeing different aspects of children’s behaviour and mental health,” said Keith Herman, professor in the University of Missouri (MU), College of Education.

For the study, the team completed profile analyses of 643 children in early elementary school to explore how patterns between student, teacher and parent reporting can be used to gain a holistic picture of a child’s mental health.

Herman suggested that mental health professionals could work with teachers and parents to identify depressive symptoms early by including self reports from children in mental health evaluations.

“The gold standard for identifying children who might be at risk for developing depression later in life is to ask the children themselves,” noted Herman.

“However, even if a child doesn’t say they feel depressed, certain outward behaviours might provide clues to the state of the child’s mental health. It’s important for teachers and parents to catch these behaviours early to prevent long-term problems that occur with depression,” he said. (IANS)
