Dementia generally refers to the deterioration of the brain that impairs the ability to remember, think, or make everyday decisions. Alzheimer’s disease is the most common type of dementia, and there is currently no cure for dementia. Though dementia is most common in older adults, it is not part of normal ageing.
In the short term, “dementia rates may drop temporarily as a result of the high number of deaths of people with dementia due to COVID-19, with between 25 to 45 percent of all COVID-19 deaths estimated to be of those with dementia,” the London-based research group said this week.
However, it added that in the long term, the amount of people experiencing symptoms of dementia could rapidly increase ‘due to the neurological impact of COVID-19.’ Since the coronavirus first originated in China in late 2019, over 218 million cases of COVID-19 have been reported, with just over 18 million in the past month, according to Johns Hopkins University.
The true number of global cases is thought to be much higher than reported however, due to factors such as lack of initial testing when the pandemic first emerged and inadequate capacity to report cases.
