As a result, more people are being correctly diagnosed with prion diseases, contributing to the perception of increased prevalence. Prion diseases, such as sporadic Creutzfeldt-Jakob disease (sCJD), are more common in older individuals. As life expectancy has increased in many parts of the world, there is a larger aging population. 

According to National Library of Medicine, Another form of acquired prion disease is iCJD. There have been at least 485 iCJD cases reported worldwide; 96.7% of them were identified before 2012. In addition to a small number of iCJD cases being caused by neurosurgical instrument contamination (four cases), contaminated electroencephalogram (EEG) needles (two cases), corneal grafts (two cases), and gonadotrophic hormone (four cases), the majority of the iCJD cases were caused by administrations of growth hormone (226 cases) and dura mater grafts (228 cases) derived from human cadavers with undiagnosed CJD contaminations. 

The risk of prion diseases generally increases with age, and as the elderly population grows, so does the pool of individuals at risk. This demographic shift can lead to a higher prevalence of prion diseases. Health authorities and organizations have improved their reporting mechanisms and data collection processes for prion diseases. This includes mandatory reporting of suspected cases and the establishment of national and international surveillance networks. Enhanced data collection and reporting lead to more comprehensive epidemiological data, making it easier to track and quantify the prevalence of prion diseases. Certain environmental factors, such as contaminated medical equipment or dietary sources, have been associated with prion disease transmission. Instances of such contamination may lead to localized outbreaks and an increase in reported cases. Awareness of these environmental factors has led to stricter regulations and guidelines in healthcare settings and the food industry to reduce the risk of prion disease transmission, but sporadic cases can still occur.
