When cognitive decline begins, it becomes visible quickly.
Mental health deaths jumped from 328 in 2008 to 6,593 in 2024, with Alzheimer's and dementia accounting for 94.5% of cases. Colombia shows unique gender disparity: 2 women diagnosed with Alzheimer's for every 1 man, double the international ratio, linked to lower education and active caregiving roles.

Deaths from mental disorders in Colombia surged 1,910% since 2008, driven by population aging and increased diagnoses of Alzheimer's and dementia. Women face disproportionate risk due to gender-based educational and social disparities.
Colombia is aging faster than its health system can manage, and the numbers tell a story of a country unprepared for what comes next. Deaths from mental disorders have exploded from 328 in 2008 to 6,593 in 2024—a staggering 1,910% increase in just sixteen years. The surge is driven almost entirely by Alzheimer's disease and other dementias, which together account for more than 94 percent of these deaths. But the raw statistics mask a more troubling reality: the crisis is not distributed evenly. Women are dying at rates that far exceed men, and the reasons reveal deep fractures in how Colombian society has treated its aging population.
The demographic shift is undeniable. In 1964, people over 60 made up just 4.9 percent of Colombia's population. By 2024, they represented 15 percent. The aging index—a measure comparing older adults to children—jumped from 38 elderly per 100 young people in 2019 to 47 in 2024, and is projected to reach 60 by 2029. This transformation has strained every part of the system. The dependency ratio, which measures how many working-age people must support the elderly, climbed from 13.4 to 15.25 in the same period and is expected to hit 17.9 within four years. The pressure is mounting, and the infrastructure to handle it is not.
What makes Colombia's situation distinctive is the gender dimension. Women account for 56 percent of the population over 60, but they carry a disproportionate burden of disease. The prevalence of Alzheimer's among women reaches 246.7 cases per 100,000 inhabitants, compared to 134 in men. More striking still: for every man diagnosed with Alzheimer's in Colombia, two women receive the same diagnosis—a ratio that doubles the international average of 1.3 to 1. Diego Rosselli, a neurologist and epidemiologist at Javeriana University, argues this gap cannot be explained by biology alone. The answer lies in history and inequality. Today's elderly women had less access to education than their male peers, and low education is a documented risk factor for cognitive decline. Many continue to perform active social roles—caring for grandchildren, cooking, shopping—so when cognitive deterioration begins, it becomes visible quickly. Older men, by contrast, tend toward isolation, which can delay diagnosis and mask the progression of disease.
The prevalence of Alzheimer's and other dementias has climbed steadily. In 2019, there were 139.6 cases per 100,000 inhabitants. By 2023, that number had risen to 191.7. The risk accelerates with age: it is 265 times higher for people over 80 than for younger adults. The Ministry of Health reports that 91.3 percent of diagnoses occur in people over 60. Yet diagnosis itself is not evenly distributed. In wealthier urban areas with better infrastructure, more cases are identified and recorded. In peripheral regions, a vast undercount persists because there are simply not enough doctors and mental health services to detect disease. This creates a false picture—the data suggest mental illness is more common in richer areas, when in fact it may be more common everywhere, but only visible where professionals exist to see it.
Experts are careful to note that the surge cannot be attributed to a single cause. Piedad Urdinola, director of Colombia's National Administrative Department of Statistics, emphasizes this complexity. Rosselli points to several factors: increased longevity, a population that is genuinely aging, and improved access to diagnosis itself, which means more cases are now being counted and reported. But beneath these demographic and technical explanations lies a social reality that demands attention. Carlos López Jaramillo, head of psychiatry at the University of Antioquia, is blunt: Colombia faces an epidemic of mental health problems. The barriers are not just medical. Even as doctors grow more willing to diagnose, people remain reluctant to seek help. Professional care is scarce and unevenly distributed. Violence—both within families and in communities—compounds the crisis. These are not problems that better statistics will solve.
The transformation ahead will test Colombia's capacity to respond. The aging population will continue to grow. The number of people with dementia will rise. Without systemic change—more trained professionals, better access to care in underserved regions, attention to the social determinants of mental health—the curve will keep climbing. The question is not whether the crisis is real. The data have already answered that. The question is whether the country can act fast enough to meet it.

A Conversa do Hearth Outra perspectiva sobre a história
Why did deaths from mental disorders increase so dramatically between 2008 and 2024? Is it just that more people are getting sick?
It's partly that, yes—the population is genuinely aging. But it's also that we're diagnosing more cases now. Better access to doctors, more awareness, improved reporting. The real story is that we're finally seeing what was always there.
And the gender disparity—two women for every man with Alzheimer's—that's biological, right?
That's what you'd think, but no. The international ratio is closer to 1.3 to 1. Colombia's 2-to-1 ratio points to something else: education gaps, the fact that older women here were denied schooling their brothers received, and that they're still doing unpaid care work. When you're cognitively declining but you're also the one cooking and watching grandchildren, people notice faster.
So the diagnosis rate is actually higher because women's decline is more visible?
Exactly. And for men, isolation can hide the same disease. They withdraw, they're alone, so no one sees the problem developing. The numbers we have are shaped by who we can see, not just who is sick.
What about the regions that don't have good mental health services? Are they being left out of these statistics?
Completely. In peripheral areas, there's massive underreporting because there aren't enough doctors. So the data show mental illness is more common in wealthy urban areas, but that's likely an illusion. The disease is probably everywhere—we just can't see it where there's no one to diagnose it.
If this is an epidemic, what would actually stop it?
You'd need more psychiatrists and neurologists in underserved regions. You'd need to address poverty, violence, social exclusion—the things that actually drive mental illness. And you'd need people to feel safe seeking help. Right now, even when doctors are willing to diagnose, many people won't ask for it.
