Non-responders

In a medical or scientific context, 'non-responders' are individuals or groups who do not exhibit a significant positive reaction or benefit from a particular treatment, intervention, medication, or stimulus. This lack of response can manifest in various ways, depending on the context. It could mean a failure to achieve the desired physiological effect, a lack of improvement in symptoms, or an absence of behavioral change. Identifying non-responders is crucial for personalizing treatments, understanding the mechanisms of action of interventions, and improving the efficiency of research and clinical practice. Their study helps researchers determine why some people may react differently than others, which can lead to improved treatment strategies or the development of alternative therapies. The term can also apply in non-medical situations like the context of marketing where there are groups of people that do not respond to advertisement.
