"With more of us living into old age than at any other time, dementia is
increasing steadily worldwide, with major individual, family, societal and
economic consequences.
Treatment remains largely ineffective and aspects of the underlying
pathophysiology are still unclear. But there is good evidence that
neurodegenerative diseases – and their manifestation as dementia – are not an
inevitable consequence of ageing.
Many causes of dementia, including viral infections, are preventable.
COVID and other viral infections are centrally involved in insults to the brain
and subsequent neurodegeneration. COVID-positive outpatients have a more than
three-fold higher risk of Alzheimer’s and more than two-fold higher risk of
Parkinson’s disease.
A study of almost three million found risks of psychiatric disorders following
COVID infection returned to baseline after one to two months. But other
disorders, including “brain fog” and dementia, were still higher than among
controls two years later.
Among more than six million adults older than 65, individuals with COVID were
at a 70% higher risk than the uninfected for a new diagnosis of Alzheimer’s
disease within a year of testing positive for COVID.
More than 150,000 people with COVID and 11 million controls have been involved
in a study of long-term consequences of acute COVID infection. A year after
infection, there was an overall 40% higher risk (an additional 71 cases per
1000 people) of neurologic disorders, including memory problems (80% higher
risk) and Alzheimer’s disease (two-fold higher risk). These risks were elevated
even among those not hospitalised for acute COVID."
