Avoiding social media for a week can reduce symptoms of anxiety, depression, and insomnia, according to a study published in JAMA Network Open. The study measured the mental health of a group of 373 people aged 18 to 24 in the US before and after a week without using Facebook, Instagram, Snapchat, TikTok, or X. The authors caution that the durability of these results and their associations with behaviour require further research.

According to a study published in the journal JAMA Health Forum, the use of the benzodiazepine lorazepam by the character Victoria Ratliff in the series The White Lotus was associated in the United States with an increase in Google searches for this medication, including queries about how to obtain it online. The series generated 1.6 million more searches than usual over a 12-week period. Although the study reflects searches for information and not actual consumption, the abuse of anti-anxiety drugs is a fact: illegal sales of benzodiazepines have increased in the United States, and Spain leads the rankings in terms of consumption.

Different antidepressant drugs cause different side effects in the body, in parameters such as heart rate, blood pressure or body weight, according to a meta-analysis published by The Lancet. For example, agomelatine administration is associated with weight loss, while other molecules such as maprotiline are associated with weight gain. The research brings together 151 studies and 17 reports from the US Food and Drug Administration (FDA), including more than 58,000 people and comparing 30 antidepressant drugs with a placebo.

In women suffering from post-traumatic stress disorder (PTSD) after experiencing sexual assault, the connectivity between two areas of the brain within the fronto-limbic system is altered, according to a study presented at the European College of Neuropsychopharmacology conference held in Amsterdam (Netherlands). The study, led by a researcher at Hospital Clínic in Barcelona, compared brain images of 40 women with PTSD following a recent sexual assault and 45 control cases. In 22 of these 40 women, communication between the amygdala—which helps process emotions such as fear—and the prefrontal cortex—which helps regulate those emotions—had almost completely disappeared.

Until now, perceived well-being followed a U-shaped curve depending on age, declining – due to worry, stress or depression – until people reached middle age, around 50, and then rebounding into old age. With malaise, the U is inverted and we talk about the ‘unhappiness curve’, shaped like a hump. Now, research published in PLOS One with data from the US and the UK claims that this age-related malaise is declining and that there is no longer such a hump. The reason for the change is said to be the deterioration of mental health among young people, especially those under 25. The study also includes data from 44 countries between 2020 and 2025, including Spain, and confirms that the malaise no longer takes the form of a hump, but decreases with age.

From 2014 to 2023, one in six people in the world suffered from loneliness, according to a World Health Organisation report, which outlines the causes of this phenomenon and its multiple impacts: on physical and mental health and mortality, as well as on work and the economy. The report estimates that loneliness is linked to more than 871,000 deaths per year and highlights a higher incidence among young people and in low- and middle-income countries.

The number of adolescents with anxiety problems seems to be increasing, especially in developed countries. An opinion article published in the journal Science proposes that maternal stress, quality of care and environmental conditions in the early years, together with current social and technological changes, may contribute to explaining this trend. 

By 2030, there will be more than 1 billion adolescents (aged 10 to 24) living in countries facing preventable and treatable health issues. This figure represents half of the world’s adolescent population, according to a new analysis by the Lancet Commission on adolescent health and well-being. Among these health issues, the study highlights HIV/AIDS, early pregnancies, risky sexual behavior, depression, poor nutrition, and injuries.

Research involving more than 200 patients with depression, whose symptoms had not improved after NHS talk therapy shows that those who took part in eight group sessions of mindfulness-based cognitive therapy saw their depressive symptoms reduced, compared with those who received treatment as usual. The study is published in The Lancet Psychiatry.

A team has analysed data from a survey of more than 3,000 teenagers aged 11-19 in the UK. Their findings show that those with mental health problems spend an average of 50 minutes more per day on social media than those who do not suffer from them. According to the authors, who publish the results in the journal Nature Human Behaviour, further research is needed to know if this is a causal relationship.
