This simple test can detect future problems.
Researchers estimate that over 55 million people worldwide are living with dementia, a broad term for diseases that impair memory, thinking, and communication abilities. Alzheimer’s disease is currently the most prevalent form of dementia. Early diagnosis is crucial, as there is no cure for dementia, but early detection can enable access to medications and interventions that may slow its progression.
A team from Murdoch University in Western Australia has developed a new screening tool aimed at detecting dementia at its earliest stages. This test, known as the McCusker Subjective Cognitive Impairment Inventory (McSCI), allows individuals to self-report concerns across six cognitive areas, including memory, concentration, and language. The findings of this research were published in the journal Age and Ageing.
According to Hamid R. Sohrabi, the lead researcher and a professor at Murdoch University, the McSCI provides a significant advancement in early dementia detection. Traditional methods are often costly and not widely accessible, making this new tool a valuable resource for identifying individuals who may need more in-depth medical assessments, such as brain imaging. The McSCI has shown a remarkable 99.9% accuracy in identifying individuals with significant subjective cognitive decline.
The McSCI consists of a 46-item questionnaire that assesses cognitive concerns in memory, language, orientation, attention, visuoconstruction abilities, and executive function. It is intended to be used under clinical supervision to avoid misinterpretation of scores. The tool is designed to be freely accessible to doctors and researchers, and future developments include an informant version and online applications to enhance its usability.
Karen D. Sullivan, a neuropsychologist, emphasizes the importance of integrating tools like the McSCI with observations from individuals who know the patient well and cognitive assessments that measure brain function. She suggests that the McSCI might be particularly effective in identifying certain dementia subtypes and highlights the need for innovative solutions to address the global challenge of diagnosing and treating dementia early.
