David Cox

David Cox brings a researcher’s mindset to health reporting, using his background in neuroscience to explain how medical science, lifestyle and health systems intersect in people’s lives. He covers health and medicine for major outlets in the UK and the US, including The Telegraph, where he reports on issues from access to treatment to the consequences of long-term lifestyle choices. His work sits at the junction of evidence-based medicine and lived experience, often using individual stories and his own data to make complex research practical for readers.

Drug shortages, medicines access and system strain

At The Telegraph, Cox writes on pressures within the health system and the way they filter down to patients, such as the current crisis in UK drug shortages and its impact on people who rely on daily medication. In that reporting he combines interviews with patients and frontline professionals with an explanation of what is happening in the wider medicines supply chain and regulatory environment. He uses individual cases to show how abstract problems like supply disruption or pricing translate into pain, anxiety and disrupted care in everyday life. His focus on access to medicines complements his broader interest in how health services cope with rising demand from chronic disease and an ageing population.

Ageing, diet and preventive health

Cox specialises in ageing, nutrition and brain health, and he returns to these themes across his work for newspapers, broadcasters and magazines. He reports on how diet, sleep, physical activity and other modifiable factors influence longevity, cognitive function and the risk of common conditions in later life. His writing links large epidemiological and clinical studies to concrete behavioural changes, often translating detailed findings on nutrients, meal patterns or exercise into clear guidance on what people can realistically do. In a widely shared piece on reversing fatty liver disease, he documents his own scan results and subsequent lifestyle changes, using his case as a way into the broader evidence on metabolic health and liver fat. He extends this preventive-health focus beyond print, appearing in television documentaries on the relationship between diet and ageing and discussing how food choices shape long-term health trajectories.

Neuroscience, mental health and the brain

Cox is a trained neuroscientist and that expertise runs through his coverage of mental health, cognition and brain-related disease. He writes frequently on topics such as mental health research, the biology of stress and anxiety, and how different therapies or interventions affect the brain. His pieces in specialist science outlets emphasise how experimental findings in neuroscience and psychiatry might change clinical practice or self-management, translating technical concepts into plain language without losing nuance. He is particularly interested in how ageing and lifestyle interact with brain structure and function, covering issues from neurodegenerative disease risk to the effects of sleep, diet and exercise on memory and mood. Across these stories he tends to foreground the mechanisms behind symptoms, showing readers what is happening in the brain as well as what treatments or habits can help.

Cross-outlet health reporting and voice

Cox works as a freelance health journalist, writing regularly for The Telegraph alongside other major outlets including the Guardian, the BBC, NBC News, WIRED, BBC Science Focus and New Scientist. This cross-outlet role means he covers a wide spectrum of health topics, from infectious diseases and emerging medical technologies to fitness, nutrition and public health policy. His portfolio includes reported features, personal essays, Q&A-style explainers and evidence-led service pieces that give readers clear takeaways grounded in current research. He often interviews clinicians, researchers and other subject-matter experts, integrating their perspectives with data from clinical trials, observational studies and health statistics. Across formats, his writing is direct and analytical, with a strong emphasis on what robust evidence shows, where uncertainty remains, and how new findings fit within the broader medical literature. In recent years he has also developed a public-facing profile as an author and speaker on ageing and health, using books, talks and social channels to extend the same evidence-based approach beyond traditional print journalism.
