Medicine in 25 Years: Healthcare for a Society of the Very Old (2051)

In 25 years, today’s 40-year-olds will be of retirement age. Medical breakthroughs over this period can hardly be predicted – population trends, on the other hand, can be predicted quite well. They will shape the medicine of 2051 more than any single technology.

About this series: “The Future of Medicine” looks ahead 5, 10, 15, 25, 50 and 100 years. From this part onwards, we mainly describe scenarios, not forecasts. This version: October 2026.

What is fairly certain: demographics

According to the population projection of the Federal Statistical Office, the number of people aged 80 and over in Germany will rise from 6.1 million in 2024 to 8.5–9.8 million in 2050. The number of people of working age, by contrast, will fall – significantly, depending on immigration. This means more people with several chronic diseases at the same time, more need for care, more dementia – and fewer people who can provide care and treatment.

Scenario 1: ageing itself becomes a target for medicine

Ageing research (geroscience) assumes that many age-related diseases have common biological causes: damage to the genome, inflammatory processes, senescent cells, declining repair mechanisms. Instead of treating heart failure, osteoarthritis and dementia individually, the medicine of the future could try to slow down these underlying processes.

Today this is mostly research. Approaches such as senolytics, which are intended to remove senescent cells, have so far shown mixed results in humans. So-called biological clocks, which estimate “biological age” from blood or tissue samples, are not yet suitable for medical decisions. By 2051, however, it is conceivable that the first medicines will have been approved whose target is not a single disease but healthy ageing.

Assessment: possible, but uncertain. Proof would require large, long-term trials.

Scenario 2: healthy years rather than just more years

What matters for quality of life is not only how old people become but how many years they spend in good health. If risk factors such as high blood pressure, excess weight, smoking and lack of exercise can be significantly reduced, people in 2051 could live not only longer but also independently for longer. Experts speak of the “compression of morbidity”: illness and the need for care are condensed into a shorter phase at the end of life.

Assessment: partly achievable – with means known today.

Scenario 3: technology in nursing care

Sensors that detect falls, medication dispensers that remind people to take their medicines, exoskeletons that help carers with lifting and robots that take over errands – much of this is being trialled today. By 2051, technology could relieve carers of physically demanding and organisational tasks. Human care and attention, however, cannot be automated. The central question will be whether technology creates more time for people or replaces staff.

Assessment: support likely; replacement of carers unlikely and not desirable.

Scenario 4: the doctor with an AI team

In 2051, a GP could care for considerably more patients than today – supported by AI systems that pre-sort findings, monitor progress and answer routine questions, as well as by specialised nurses with extended powers. The doctor’s role would shift more towards complex decisions, conversations and accompanying patients.

The big questions

• Funding: how can expensive therapies and a growing number of people in need of care be financed with fewer contributors?
• Equity: even today, life expectancy differs significantly depending on income and region. New technologies could widen or narrow this gap.
• Dignity at the end of life: the more that is medically possible, the more important conversations become about what people want for the last phase of their lives.

How we will know whether this scenario is coming true

• Development of healthy life years compared with life expectancy
• First pivotal trials with the goal of “healthy ageing”
• Number of people in need of care and of carers
• Use of assistive technology in care homes and at home
