A groundbreaking study by Australian researchers has found that women are genetically more susceptible to clinical depression than men, a discovery that could reshape future treatment strategies.
Published on Wednesday in Nature Communications, the study is one of the largest of its kind, analyzing the DNA of nearly 200,000 people diagnosed with depression to identify shared and unique genetic markers associated with the disorder.
Women Show Higher Number of Depression-Linked Genetic Markers
The research, led by the Berghofer Medical Research Institute, revealed that women have almost twice as many genetic markers linked to depression compared to men. Researchers found around 13,000 markers in women versus 7,000 in men.
“The genetic component to depression is larger in females compared to males,” said lead researcher Jodi Thomas. “Unpacking the shared and unique genetic factors in males and females gives us a clearer picture of what causes depression — and opens the door to more personalised treatments.”
Some of these genetic differences may influence biological pathways related to metabolism or hormone production, potentially explaining why women with depression often experience symptoms such as weight fluctuations or altered energy levels.
“We found some genetic differences that may help explain why females with depression more often experience metabolic symptoms,” Thomas added.
Implications for Personalized Treatment
Researcher Brittany Mitchell noted that these findings could lead to gender-specific approaches to depression treatment.
“Until now, there hasn’t been much consistent research to explain why depression affects females and males differently, including the possible role of genetics,” Mitchell said. “Many medications and studies have primarily focused on men, leaving a gap in understanding treatment for women.”
With over 300 million people worldwide affected by depression, according to the World Health Organization, these insights could play a crucial role in improving mental health care globally.
By identifying the unique genetic components that make women more susceptible, this study marks a significant step toward personalized medicine for mental health, promising more effective and tailored treatment options in the future.
