A study published in the journal Scientific Reports reveals an increase in simplicity, negativity, and stress-related words in pop song lyrics in the United States over the last few decades. The authors also conclude that this phenomenon was attenuated in times of social crisis, such as the COVID-19 pandemic, which ‘highlights the role of music in both shaping and reflecting moods.’ The data included more than 20,000 songs from the US charts between 1973 and 2023. 

A meta-analysis published in The Lancet Psychiatry journal concludes that the most effective way to discontinue antidepressant treatment in people with remitting depression is to gradually reduce the dose in combination with psychological therapy. Furthermore, this strategy proved to be just as effective in preventing relapses into depression as continuing medication. The study was based on data from more than 17,000 adults with depression and anxiety in remission, although the evidence for the latter disorder was not as robust. 

A study published in Scientific Reports concludes that adults who use Instagram very frequently overestimate their ‘addictive’ use, which complicates self-control and increases feelings of guilt. According to the research, excessive use, in most cases, is not an addiction but a habit. The study was conducted on more than 1,000 Americans and suggests that the fact that many think they have an ‘addiction’ may be related to the media's frequent use of this term when talking about social media. 

Consuming up to four cups of coffee a day is associated with an increase in telomere length in people with severe mental disorders, such as schizophrenia or bipolar disorder. Telomere length is an indicator of cellular ageing and is shorter in people with these disorders, although the causes are not clearly understood. According to the study, published in BMJ Mental Health, the effect shown is comparable to ‘a biological age five years younger’ in coffee drinkers. 

A new article published in eClinicalMedicine measures mental health problems in the Gaza Strip among the population over 40 years of age before and after the genocide committed by Israel. The study indicates that the proportion of these adults experiencing high levels of distress has tripled in the last five years, with a peak following the escalation of the massacre since October 2023. It was already known that chronic stress factors affecting victims pose a serious threat to mental health, but no longitudinal study had yet been conducted comparing distress in the same individuals before and after the genocide.  

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.
