Study Finds Highest Mental Disorder Burden Among Adolescents Aged 15–19

India’s mental health burden is rising at an alarming pace, with anxiety, depression, and other psychiatric disorders increasing sharply over the past three decades, according to a new analysis from the Global Burden of Disease Study published in The Lancet.

The findings paint a concerning picture for a country with one of the world's largest youth populations and limited mental health infrastructure. Between 1990 and 2023, anxiety disorders in India surged by 123%, while major depressive disorder prevalence rose from 2,147 to nearly 2,800 cases per lakh population. Chronic low-grade depression, known as dysthymia, also increased, while schizophrenia rates climbed from 316 to 321 cases per lakh.

Globally, an estimated 1.2 billion people now live with mental health conditions—almost double the number recorded in 1990. While population growth and ageing explain part of the rise, researchers say the increase reflects a broader shift in mental wellbeing.

Dr. Damian Santomauro, lead author of the study and Associate Professor at the Queensland Centre for Mental Health Research, noted that global mental disorder cases increased by 95.5% between 1990 and 2023. Even after adjusting for population growth and ageing, age-standardised prevalence rates rose by 24.2%, indicating a genuine increase in mental health problems.

The study identified South Asia as one of the regions experiencing the largest growth in mental health burden. Among women and girls, the impact was particularly severe, with age-standardised disability-adjusted life year (DALY) rates increasing by 44.2% between 1990 and 2023.

Researchers believe multiple factors may be contributing, including the lingering effects of the COVID-19 pandemic, poverty, social inequality, domestic violence, conflict, climate-related stress, and declining real-world social connections in an increasingly digital society.

One of the most striking findings was that mental health burden now peaks among adolescents aged 15 to 19 years, driven largely by rising rates of anxiety and major depression. Historically, mental disorders were more common in middle age.

The findings underscore an urgent reality: mental health is no longer a silent issue but a public health priority demanding immediate attention.

Menstrual Blood Test May Detect Endometriosis Without Surgery: Study

For millions of women living with unexplained pelvic pain, a diagnosis may finally be getting closer—without the need for surgery.

A new study published in Nature suggests that endometriosis, a painful and often overlooked gynecological condition, could one day be detected through a simple analysis of menstrual blood. The breakthrough offers hope for faster, safer, and more accessible diagnosis of a disease that affects nearly 10% of women of reproductive age worldwide.

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the womb, commonly affecting the ovaries, fallopian tubes, and pelvic tissues. The condition can cause severe menstrual pain, chronic pelvic discomfort, heavy bleeding, fertility problems, and fatigue. Yet diagnosis is often delayed by seven to ten years, leaving many women to suffer without answers.

Currently, the gold standard for diagnosing endometriosis is laparoscopy, an invasive surgical procedure that carries risks and is not easily accessible to everyone. Researchers are now exploring whether menstrual blood can provide the same clues without surgery.

The study found that menstrual blood contains biological markers that differ between women with and without endometriosis. Scientists are investigating changes in immune cells, inflammatory signals, and genetic markers linked to the condition. These differences could eventually form the basis of a non-invasive diagnostic test.

If validated, such a test could transform women's healthcare. It may allow earlier diagnosis, reduce years of misdiagnosis, and improve access to screening, particularly in low-resource settings where surgical testing is difficult to obtain. Young women, whose symptoms are often dismissed or overlooked, could especially benefit from earlier detection.

However, researchers caution that the test is still in development. Larger studies are needed to confirm its accuracy and reliability before it can replace current diagnostic methods.

Experts emphasize that women experiencing chronic pelvic pain, severe menstrual cramps, painful intercourse, heavy bleeding, or unexplained fertility issues should seek medical evaluation.

Researchers Find Association Between Junk Food and Childhood Behavioral Issues

What children eat may shape more than their physical growth—it could also influence their emotional and behavioral well-being from a very young age.

A new study from researchers at the University of Agder (UiA) in Norway has found a strong link between diet and mental health in four-year-old children. The findings suggest that children who regularly eat fruits and vegetables tend to show fewer signs of anxiety, sadness, restlessness, and behavioral difficulties, while those consuming more sugary and salty snacks are more likely to exhibit disruptive behaviors.

The study analyzed dietary habits and behavior patterns of 363 Norwegian preschoolers. Parents reported how often their children consumed different foods, while researchers assessed the children's emotional and behavioral health using standardized questionnaires.

The results revealed a clear pattern. Children who ate fruits and vegetables more frequently scored lower on both internalizing problems, such as anxiety, withdrawal, and sadness, and externalizing problems, including anger, hyperactivity, and concentration difficulties.

In contrast, frequent consumption of sweets and savory snack foods was associated with more behavioral problems. Researchers noted that the negative impact of unhealthy foods appeared even stronger than the protective effect linked to fruits and vegetables.

Scientists believe several factors may explain the connection. Fruits and vegetables are rich in nutrients such as antioxidants, folate, vitamins, and minerals that support brain health and help reduce inflammation and oxidative stress. Meanwhile, diets high in sugar and unhealthy fats may negatively affect brain function and development.

The benefits may also extend beyond nutrition. Healthy meals are often shared during family mealtimes, which can promote emotional well-being, social interaction, and a supportive home environment.

With mental health challenges increasingly affecting children and adolescents worldwide, the findings highlight the importance of healthy eating habits early in life. The message is simple: a healthy plate may help nurture a healthier mind.
