According to a study, Covid survivors who continue to have poor focus, memory problems, and other cognitive disorders are at a high risk of getting dementia years later.
According to the Strait Times, there is also growing fear that some of these “long-haulers” may develop dementia-related alterations sooner than predicted.
“Anything that reduces a person’s cognitive reserve and resilience will allow neurodegenerative processes to accelerate,” said Alireza Atri, a cognitive disorder neurologist and director of the Banner Sun Health Research Institute.
Symptoms of neurological illnesses, such as dementia, may therefore appear earlier as a result, he added.
Dementia is a broad term describing a person’s reduced capacity to recall, reason, or make decisions, which interferes with their daily activities. It is caused by diseases such as Alzheimer’s and brain traumas, and it primarily affects adults aged 65 and up.
According to Atri, Covid-19 could exacerbate this process, hastening cognitive impairment and eventually dementia, according to the paper.
“Assume I’m in my 50s, and I’m on track to develop dementia symptoms in my late 60s or early 70s, and I already have these toxic proteins and certain difficulties. Covid-19 might come in and stoke the fires even more “Atri said.
Atri stated that in addition to the neurological symptoms of Covid-19, such as loss of taste and smell, those who have been on it for a long time should look out for “brain fog, issues with attention and concentration, more effortful mental processes, possibly amnesia.” Anxiety and sleep problems are also possible.
He added that there is another reason why individuals should get immunised.
Researchers discovered more than 50 long-term impacts of Covid-19 in a recent study published in the journal Scientific Reports. They discovered a high prevalence of neurological symptoms such as dementia, depression, anxiety, and obsessive-compulsive disorders, in addition to hair loss, shortness of breath, headache, and cough.
According to another study published in the journal The Lancet Psychiatry, one in three persons who survived Covid-19 were diagnosed with anxiety and mood disorders within six months of infection.
Although neurological diagnoses such as stroke and dementia were uncommon, 7% of persons admitted to intensive care had a stroke, and nearly 2% had dementia.
