Homecoming 2026 Will Have Answers for Long Covid
A
new study underscores just how devastating Covid-19 can be on a
person’s long-term health. Researchers from the Imperial College London
and the University of Cambridge have linked severe Covid with cognitive
decline on par with 20 years of brain aging. For example, someone in
their 50s would have the mental capabilities of someone in their 70s, as
a result of severe Covid.
The small trial, published in The Lancet’s eClinicalMedicine
journal, involved 46 people who had previously been hospitalized with
severe Covid-19; 16 of which were put on a ventilator during
hospitalization. Six months after their recovery, participants were
given a range of complex cognitive tests. They were also matched up with
healthy control subjects.
The Study Results
Patients with Covid exhibited slower response times to tasks, and their
responses were not as accurate compared to the control group. Covid
patients also tested lower than the control group in verbal analogical
reasoning tests, which measure cognitive and linguistic skills.
The degree of cognitive difficulties corresponded with the severity of
patients’ infections. Those who required ventilation while in the
hospital had the most profound reductions in cognitive function.
“COVID-19 survivors were less accurate and slower in their responses
than expected compared to their matched controls. Acute illness, but not
chronic mental health, significantly predicted cognitive deviation from
expected scores. The most prominent task associations with COVID-19
were for higher cognition and processing speed, which was qualitatively
distinct from the profiles of normal aging and dementia and similar in
magnitude to the effects of aging between 50 and 70 years of age. A
trend towards reduced deficits with time from illness did not reach
statistical significance.”
While more research is definitely needed, scientists theorize that
severe Covid may damage the brain by affecting oxygen supplies and
clotting and/or causing bleeds during the acute phase of illness.
Conclusion
“In summary, severe COVID-19 illness is associated with significant
objectively measurable cognitive deficits that persist into the chronic
phase. The scale of the deficits correlates with clinical severity
during the acute phase as opposed to mental health status at the time of
assessment, shows at best a slow recovery trajectory and the
multivariate profile of deficits is consistent with higher cognitive
dysfunction as opposed to accelerated aging or dementia.”
This article addresses the effects of Covid only, which can be
devastating. We will discuss the more severe cases of Long Haul Covid
at January 22-25 Brimhall Homecoming in Tempe Arizona. We will share
the research of the Chiropractic Neurologists at that time. Many of the
complicated cases you are treating know have Long Haul Covid. Unless
you address the underlying issue, your results will be less that
adequate.
Yours in Health and Wellness,
