A screening operation for Alzheimer's disease was conducted at the CHU Habib-Bourguiba hospital in Sfax, Tunisia, on September 20, 2026. The operation involved 25 neurologists from both public and private sectors. A total of 400 people were sensitized, and 101 memory tests were performed. The results showed that 33 individuals, or 32.7%, presented signs that warrant further specialized follow-up.
The outcome of the screening operation is significant, but it does not provide an estimate of the prevalence of Alzheimer's disease in Sfax. It is essential to note that the individuals who underwent testing were a selected population that voluntarily participated in the screening operation. Therefore, they do not represent a random sample of the Sfax population. As a result, it would be inaccurate to assume that 32.7% of Sfax residents have Alzheimer's disease or cognitive disorders.
The 33 individuals who were referred for further evaluation do not necessarily have confirmed Alzheimer's disease diagnoses. The tests revealed suspicious signs that require additional investigations. A definitive diagnosis can only be made after a more in-depth medical evaluation. The distinction between screening and diagnosis is crucial in understanding the results of the operation.
The Sfax screening operation takes place in a national context where the number of people living with dementia is expected to increase significantly. According to the Global Burden of Disease 2019 study, there were approximately 95,059 people living with dementia in Tunisia in 2019. This number is projected to rise to 329,849 by 2050. These numbers are based on statistical estimates and projections, highlighting the need for accurate epidemiological data.
The screening operation in Sfax highlights the importance of early detection and the need for robust epidemiological data to measure the evolution of cognitive disorders in Tunisia. The results of the operation should not be extrapolated to the national or regional level. Instead, they emphasize the value of targeted screening initiatives in identifying potential cases of Alzheimer's disease.
The Sfax hospital screening operation involved a significant mobilization of resources, including 25 neurologists and a substantial number of tests. The fact that 400 people were sensitized and 101 tests were performed demonstrates the effort to raise awareness and detect potential cases of Alzheimer's disease. However, it is crucial to interpret the results within the context of the screening operation.
The issue of Alzheimer's disease in Tunisia is likely to become increasingly pressing due to demographic changes. The country's population is aging, and the number of people living with dementia is expected to rise. As a result, there will be a growing need for accurate diagnoses, effective treatments, and support services for individuals affected by Alzheimer's disease and their families.
Key points
- 33 potential cases of Alzheimer's disease were identified out of 101 tests conducted at a hospital in Sfax, Tunisia.
- The screening operation does not provide an estimate of the prevalence of Alzheimer's disease in Sfax, as the tested population was not representative of the general population.
- The number of people living with dementia in Tunisia is expected to increase significantly, from 95,059 in 2019 to 329,849 by 2050.
