Covid, “brain fog” among the long-term effects: research by the Alzheimer center

The fog In the brain, according to experts, it falls within the long-term effects of Covid: many patients, recovered from Covid, in fact show that they have suffered post-covid consequences also on a cognitive level. An impact on health that can occur even months after recovery. Several studies were in fact presented at the international conference ofAlzheimer‘s Association. Where we talked, therefore, of “brain fog” and other cognitive disorders that occur even several months after recovery: elderly patients, already affected by cognitive disorders, are most affected. Among these symptoms are therefore disturbances in concentration, confusion, forgetfulness and other worrying signs of memory loss. The studies will also be carried out to understand if, over time, these disorders pass and remain even over the years. The time limit, in the case of Covid, obviously casts doubt on the repercussions on the physical: temporary or permanent.

Fog in the brain after Covid, what happens

«A large portion of our patients in the Covid recovery program – said Dr. Thomas Gut, director of the Post-Covid Recovery Center at Staten Island University Hospital – shows cognitive signs and symptoms long after the inflammatory phase of Covid has passed. We generally see many patients with predominant nasopharyngeal disease returning to us with more neurocognitive deficits. Many of the cognitive changes that we see mirror Alzheimer’s disease or post-traumatic stress disorder in many ways. What is becoming clearer is that the severity of the acute infection does not necessarily indicate the neurocognitive changes that will ensue after the acute phase has passed. In fact, we have many patients who have had a mild infection or disease who have a lot of difficulty with memory or behavior changes».

Researchers at the University of Thessaly examined the cognitive function and general health of 32 patients affected by Covid two months after admission and found that more than 50% experienced cognitive decline, particularly with short memory. term. They also found that lower memory and thinking scores were associated with lower oxygen saturation.

Pfizer, after 6 months the vaccine “prevents 97% of serious forms of Covid”: the new monitoring

Also in the University of Texas Health Science Center, experts studied the cognition and olfactory senses of 300 Argentine Amerindian seniors who had been cured of Covid and found that 50% had persistent problems with forgetting and 25% had additional problems. with language and executive dysfunction. Blood samples from 310 patients, all admitted to NYU Langone Health for contracting Covid, were studied at New York University’s Grossman School of Medicine, which would indicate inflammation and brain damage: damage to the blood-brain barrier, caused by inflammation , can result in the brain being unable to send information to other parts of the body.
