Fact Check: "Dementia can affect cognitive functions such as memory and reasoning."
What We Know
Dementia is defined by the World Health Organization (WHO) as a syndrome that leads to a decline in cognitive functions, which includes memory, thinking, behavior, communication, judgment, and the ability to perform daily activities. This decline is beyond what is typically expected from the aging process. The WHO emphasizes that dementia can affect individuals of all ages, although it is most prevalent among those aged 65 and older.
The Department of Health and Aged Care further elaborates that dementia encompasses various types, including Alzheimer’s disease and vascular dementia, all of which can impair cognitive functions such as memory and reasoning. The Australian Institute of Health and Welfare indicates that dementia is a significant health concern, with projections suggesting that the number of Australians living with dementia will rise dramatically in the coming years.
Analysis
The claim that "dementia can affect cognitive functions such as memory and reasoning" is well-supported by multiple credible sources. The WHO's definition of dementia explicitly states that it leads to a decline in cognitive function, which includes memory and reasoning abilities. This aligns with findings from the Department of Health and Aged Care, which lists memory and thinking as key areas affected by dementia.
The reliability of these sources is high. The WHO is a reputable international public health agency, and the Department of Health and Aged Care is a governmental body in Australia dedicated to health issues. Both organizations provide evidence-based information and are recognized authorities in the field of public health.
Furthermore, the National Dementia Support Program (NDSP) emphasizes the importance of understanding dementia and its effects on cognitive functions, reinforcing the claim's validity (source-2). The consistent messaging across these reputable sources strengthens the assertion that dementia significantly impacts cognitive functions.
Conclusion
Verdict: True
The claim that "dementia can affect cognitive functions such as memory and reasoning" is substantiated by authoritative sources, including the WHO and the Department of Health and Aged Care. Both organizations confirm that dementia leads to cognitive decline, affecting memory and reasoning abilities, which is a critical aspect of the syndrome.
