Late-life depression: Learn to spot the signs early – DW – 07/25/2025
It is perhaps the last place you would expect to find a generational divide, but even in mental health, we (those of us of a certain age) are told, "We (those of us of a younger age) are more aware of mental health than you" — as if awareness alone could remedy depression.
There is actually some truth to this.
"There are shifts in younger generations and also in older generations. But unfortunately mental health is still very stigmatized for older adults," said Pascal Schlechter at the Institute of Psychology, University of Münster, Germany. "It's quite a big step [for some people] to admit, 'I have a mental health problem and I want to talk about it.'"
But it's not only older patients who lack awareness or a willingness to talk about depression. It can also be their doctors, who may misdiagnose a mental health problem as a physical one, common when you grow old.
"If a 30-year-old tells you they've stopped going out and are withdrawing [from social interaction], you would ask them, 'Is anything wrong with your mental health? Are you depressed?'," said Schlechter. "But with an older person, you might say, 'You're fatigued. It's just part of the normal aging process. Just rest.'"

The generational divide closes when we talk about symptoms of depression — there is little to no difference in depression between younger and older adults.
While at Cambridge University in the UK, Schlechter co-published a paper on the development of depressive symptoms in older adults, based on the results from a longitudinal study that tracked the progress of more than 11,000 people over a period of 16 years.
Schlechter and colleagues found the same symptoms in older adults as in younger adults: Patients expressed they , or that , they , had , or felt .
However, they noted: "In older adults, depression often presents with more somatic symptoms than in younger populations."
When we spoke in July 2025, Schlechter added: "Medical or somatic symptoms may be part of a depression, but [older adults] often misattribute these symptoms to their aging process. This can lead to delayed recognition, [and as a result] their depression may manifest more chronically."
So, there is that difference: Whether it's due to a lack of awareness among patients and physicians, or stigma, depression can be worse for older people.
That may be because the depression is combined with — or, in part, "triggered" by — a somatic (physical) illness, or symptoms of depression were left unaddressed earlier in life — perhaps also due to a lack of awareness or stigma.
As with most illnesses the earlier depression or anxiety are diagnosed, the better the chances of treating them.
Some social factors also contribute to depression. As we enter late life, we are often forced to adjust to changes in our social status, our identity through work or elsewhere in a community, and people start dying around us. We may even experience abuse from our carers, as highlighted information from the World Health Organization on depression — another, potential contributing factor.
All these things can bring what may have been a mild, latent depression to the fore in a chronic and severe way.
There is a sense when talking to experts in the field that physicians may prefer to tackle physical ailments in older adults than mental ones.
No matter what age a person is, depression is difficult to treat. But when older adults present with both physical and mental health problems, it is even harder.
"In both poorer and richer health systems in Europe, one of the main instruments we have to deal with depression is medication," said Albino Oliveira-Maia, who heads the Neuropsychiatry Unit at the Champalimaud Foundation in Lisbon, Portugal.
"When treating older adults [with] medication, [there is a] higher likelihood for interaction with other medication and for toxicities [to occur]," Oliveira-Maia told DW. "That might mean physicians pay more attention to physical health problems than mental health."
But medication is not the only treatment for depression — there are also a range of psychotherapy options, or so-called talk therapies, including cognitive behavioral therapy, and many others, specific to a patient's situation.

One aspect of depression we have not touch on yet is suicide. Suicide affects all groups of people, young and old, male and female.
But regulation often prevents people from participating in research if they are known to have suicidal thoughts or show suicidal behavior. And that means there is a lack of understanding and knowledge among researchers.
"This is obviously an ethical concern," said Oliveira-Maia. "It's an act of generosity to participate in a research program, so we need to protect the people. But in doing that, there are sometimes consequences that lead to slower progress for some of the patients that are most in need."
People over 65 years can also be excluded from trials if they have existing medical conditions, such as vascular lesions in the brain, said Oliveira-Maia.
Scientifically, this makes sense, even if only from a cold, unemotional perspective: If people die or their illnesses worsen during a trial, it can make it impossible for other teams to verify the results — which is a standard process and safety net in research, especially in the development of new medication.
Both Schlechter and Oliveira-Maia have reservations about awareness campaigns, and specifically about self-diagnosis, which can go either way — a younger person may be more inclined to say, "Yes, I have a mental health problem" even if they don't, and an older person may deny all the signs.
"For younger generations, there is more public awareness due to social media. And there are good campaigns that provide valid information," said Schlechter. "But there's also a lot of misinformation out there."
Oliveira-Maia, meanwhile, is concerned about people misdiagnosing themselves, whether they are young or old.
"While [they are] valuable, there is also some data to suggest that the awareness campaigns can in themselves lead to misclassification in that some people that are healthy can value their normal symptoms of sadness and anxiety as a mental health problem."
The solution, as always with any illness or symptom that concerns you, is to speak to a health professional you can trust.

Hazardous 'forever chemicals' found in period products – DW – 07/26/2025
Period underwear and menstrual cups are touted as an environmentally-friendly alternative to pads and tampons. Now a team of researchers has discovered that they can contain risky "forever chemicals," or PFAS. The name sounds almost poetic: forever chemicals. But these are perfluoroalkyl or polyfluoroalkyl substances (PFAS), which get their name from the fact that they practically never decompose — and stay in our environment forever. They also have serious consequences for humans. Some PFAS are carcinogenic, while others have an effect on the immune system or reduce the effectiveness of vaccinations. "PFAS can affect fertility, sperm quality or even the development of the child in the womb," toxicologist Marike Kolossa-Gehring told the German TV show . Forever chemicals have also been linked to thyroid disorders and high blood pressure. Now, a research team in the US has found that these chemicals can be found in reusable period products. Almost a third of the period underwear, menstrual cups and reusable pads tested by the scientists were made using these toxic chemicals. The team, led by Alyssa Wicks and Graham Peaslee at the US University of Notre Dame, tested 59 reusable period products from North America, South America and Europe. The researchers found low levels in some products, which were most likely packaging residues. But in some products, the levels were so high that PFAS must have been used in the manufacturing process — even though they would work just as well without the toxic chemicals. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video "We found PFAS in some, but not all of the products," Peaslee, a physicist and professor emeritus at Notre Dame University, told DW. "So it's not necessary. Some don't have PFAS, and they sell fine." The chemicals can cause harm to humans in two ways. The direct route is absorption through the skin of the wearer. "The skin absorbs between 1% and 50% of PFAS in the product," said Peaslee. "Even if only 1% or 2% are absorbed, that's still bad." The indirect route endangers not only the individual using the item, but everyone else, too. When the products are disposed of, the chemicals end up in our water cycle, where, as their name suggests, they do not decompose. People the wind up absorbing PFAS via their drinking water or food that has been irrigated with contaminated groundwater. "These products are sold as eco-friendly, because they produce less waste than single-use products," says Peaslee. "But this chemical class is particularly terrifying, because they're everywhere and don't go away." PFAS are widespread. They are water and dirt repellent, as well as resistant to pressure and heat. This makes them attractive for companies like clothing and packaging manufacturers. Forever chemicals can be found in water-repellent jackets or shoes, in tents and in food packaging. PFAS are even used in cosmetics to alter the consistency of the product, or as a colorant, for example. With the study, Wicks, Peaslee and their team want to raise awareness of the dangers of PFAS in menstrual products, both among companies and consumers. They do not mention brand names in their published report. "We didn't want to be sued," said Peaslee, adding that could easily happen in the US. The researcher said that it would be more cost-effective for producers to omit PFAS from their products, as these materials are expensive. However, at the end of the day, he expects any industry move away from PFAS will primarily be driven by consumers. "Consumers have a lot of market power," says Peaslee. "Consumers should ask [whether products are manufactured without PFAS] and be vocal about their choices. If there's demand, companies will start to test for [the chemicals] and say when their products don't contain PFAS. And companies won't lie, because they don't want to get sued, either."

Germany sees loneliness epidemic among young people – DW – 07/26/2025
"How do I find friends?" is the most common question German influencers get asked on social media. Loneliness has become a pressing issue in Germany, with far-reaching consequences. Three years ago, Felix Wunnike realized he had struck a chord with young people. Whenever the business psychology graduate posts videos on his TikTok account about "finding friends," his followers respond immediately. "Even when I just said in the video, 'Send this video to your best friend,' the top comment with the most likes was always something like, 'I don't have any friends,'" Wunnike told DW. "I noticed that many of my younger followers feel really lonely and say that they really don't have any friends at all. That shocked me a lot." While loneliness can make it more difficult for adults to find a job and keep it, for young people it can affect their grades in school. Wunnike has now written a self-help book entitled "Everything You Need to Know About Finding a Friend." Wunnike has identified two reasons for this trend: the COVID-19 pandemic and social media. "Despite all the positive aspects, I think it's important to warn people about the downsides and dangers of social media usage, namely that we forget about real life. When we look at our friends' Instagram stories, we overlook the importance of building friendships in real life." According to a recent study by the World Health Organization, one in six people worldwide feels lonely. Among teenagers, it's even one in five. Loneliness is becoming an increasingly serious problem in Germany, according to a survey carried out by one of the country's leading public health insurers late last year. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Young people who suffer from loneliness are more susceptible to authoritarian thinking, according to Claudia Neu. The sociologist has studied what happens when loneliness causes young people to stray down a path of political extremism. She led a study which examined the connection between loneliness and anti-democratic attitudes among young people in Germany, and came to a pretty discouraging conclusion. "Young people between the ages of 16 and 23 are particularly susceptible to conspiracy theories and tend to condone the use of political violence," said Neu. "It's important to note that while a statistical correlation has been found, it does not necessarily imply causality. Not every lonely person votes for the far-right Alternative for Germany, nor does every AfD voter have elevated levels of loneliness." Neu has now written a book on this topic, entitled "Loneliness and Resentment." Her thesis is that when people no longer feel connected to society and, worse still, react to this with resentment, there is a real potential threat to democracy. She argues that lonely people are in fact victims, having experienced discrimination much more frequently than people who are not lonely. "They repeatedly feel rejected. They are frustrated when at a social get-together they once again fail to connect with anyone and return home feeling alone," she said. "This type of rejection can generate resentment. And this they see as unfair and are unable to let it go, blaming others, and ultimately becoming bitter and angry." Neu has headed the Sociology of Rural Areas department at the universities of Göttingen and Kassel since September 2016. She said living in remote areas increases the likelihood that people feel lonely, because humans depend on interaction and communication. "If there is a lack of opportunities to meet people, then there is a significantly higher risk of loneliness," Neu told DW. This then changes perceptions, she said, adding that she has found that chronically lonely people perceive spaces differently. "They see their surroundings as darker and more unsafe, they feel less comfortable both in public and in private spaces. And they are less likely to believe that their community can work well together," she said. A survey conducted by health insurer Techniker Krankenkasse showed that around 60% of people in Germany say they experience loneliness in their private lives. According to the Federal Statistical Office, 17 million people in Germany live alone — that's one in five. This represents an increase of 22% over the past two decades. According to Neu, the increasing individualization of society has both positive and negative aspects. "On the one hand, people have more freedom to choose. It has become much easier to end an unhappy partnership. On the other hand, being alone also carries the risk of becoming isolated. Nevertheless, I would be cautious about drawing a direct connection between living alone and loneliness," she warned.

Their partners and friends pass away, and their family may not be living close by. However, a recent study by the German Center for Gerontology paints a more nuanced picture. According to the study, people between the ages of 43 and 65 feel lonelier than those in old age. Stefan Stuth, who co-authored a survey entitled "Loneliness in the Second Half of Life," told DW that unemployment is a major problem. Those who lose their job in middle age feel ashamed and stigmatized. The loss of what they see as a meaningful occupation can drive them into self-imposed isolation, he said. The elderly, on the other hand, do not experience this problem. "Reaching retirement age means you no longer have to be employed. There is no longer a stigma of unemployment that leads to mental suffering," Stuth explained. However, he added, the factor that has the greatest influence on loneliness is wealth or poverty. "The lower the household income, the higher the level of loneliness," he said. "Those with low incomes and limited financial resources have fewer opportunities to participate in society. This, in turn, leads to isolation and has a negative impact on psychological well-being."While you're here: Every Tuesday, DW editors round up what is happening in German politics and society.
