COVID-19: The virus causes brain changes & Alzheimer’s-like dementia

RT reported, citing recent US research, Covid-19 may lead to the type of brain changes common in Alzheimer’s disease. A team of scientists has identified the mechanisms by which it may be causing such impairments.
According to RT, researchers behind the recent study at the Cleveland Clinic in Ohio have revealed, cognitive disorders, including dementia, are increasingly being reported as a complication of the highly contagious SARS-CoV-2 virus that causes Covid-19
The authors of the study, which was published this week in the journal Alzheimer’s Research & Therapy said “reports of neurological complications in Covid-19 patients and ‘long-hauler’ patients whose symptoms persist after the infection clears are becoming more common, suggesting that
In order to uncover the mechanisms responsible for brain-associated complications such as delirium and the loss of taste or smell that are often found in novel coronavirus patients, the researchers compared on a molecular level the host genes of Covid-19 and those responsible for some neurological disorders, RT said.
Researchers used artificial intelligence to measure the proximity between the data of both Covid-19 patients and people suffering from Alzheimer’s disease. They also analyzed any genetic factors that might allow the new virus to infect brain tissues and cells, identifying “significant network-based relationships” between Covid and Alzheimer’s.
According to the researchers, Alzheimer’s patients may be more defenseless against the deadly virus, as they have a decreased number of certain protective antiviral genes.
RT added, citing the Cleveland Clinic’s statement, “While the researchers found little evidence that the virus targets the brain directly, they discovered close network relationships between the virus and genes/proteins associated with several neurological diseases, most notably Alzheimer’s, pointing to pathways by which Covid-19 could lead to Alzheimer’s disease-like dementia.”
As researchers proved the overlap between Covid-19 and brain changes common in Alzheimer’s, they will now study the processes by which the novel coronavirus may lead to cognitive disorders and how it might be prevented from doing so.
“Identifying how Covid-19 and neurological problems are linked will be critical for developing effective preventive and therapeutic strategies to address the surge in neurocognitive impairments that we expect to see in the near future,” RT quoted study’s lead author, Feixiong Cheng.
the Cleveland researchers point out, brain-affecting complications in Covid-19 patients and those ill with other coronaviruses have been confirmed by previous studies.
One in five patients who have recovered from the severe acute respiratory syndrome (SARS-CoV-1) or the Middle East respiratory syndrome (MERS) have reported memory impairments, while people suffering from the novel coronavirus have also experienced symptoms such as disorientation, inattention, and confusion.
RT reported that another study of more than 230,000 patients has shown Covid-19 survivors who required intensive care unit admissions might be at an even greater risk of neurological and psychiatric disorders.

BENEFIT Sponsors BuildHer...
- April 23, 2025
BENEFIT, the Kingdom’s innovator and leading company in Fintech and electronic financial transactions service, has sponsored the BuildHer CityHack 2025 Hackathon, a two-day event spearheaded by the College of Engineering and Technology at the Royal University for Women (RUW).
Aimed at secondary school students, the event brought together a distinguished group of academic professionals and technology experts to mentor and inspire young participants.
More than 100 high school students from across the Kingdom of Bahrain took part in the hackathon, which featured an intensive programme of training workshops and hands-on sessions. These activities were tailored to enhance participants’ critical thinking, collaborative problem-solving, and team-building capabilities, while also encouraging the development of practical and sustainable solutions to contemporary challenges using modern technological tools.
BENEFIT’s Chief Executive Mr. Abdulwahed AlJanahi, commented: “Our support for this educational hackathon reflects our long-term strategic vision to nurture the talents of emerging national youth and empower the next generation of accomplished female leaders in technology. By fostering creativity and innovation, we aim to contribute meaningfully to Bahrain’s comprehensive development goals and align with the aspirations outlined in the Kingdom’s Vision 2030—an ambition in which BENEFIT plays a central role.”
Professor Riyadh Yousif Hamzah, President of the Royal University for Women, commented: “This initiative reflects our commitment to advancing women in STEM fields. We're cultivating a generation of creative, solution-driven female leaders who will drive national development. Our partnership with BENEFIT exemplifies the powerful synergy between academia and private sector in supporting educational innovation.”
Hanan Abdulla Hasan, Senior Manager, PR & Communication at BENEFIT, said: “We are honoured to collaborate with RUW in supporting this remarkable technology-focused event. It highlights our commitment to social responsibility, and our ongoing efforts to enhance the digital and innovation capabilities of young Bahraini women and foster their ability to harness technological tools in the service of a smarter, more sustainable future.”
For his part, Dr. Humam ElAgha, Acting Dean of the College of Engineering and Technology at the University, said: “BuildHer CityHack 2025 embodies our hands-on approach to education. By tackling real-world problems through creative thinking and sustainable solutions, we're preparing women to thrive in the knowledge economy – a cornerstone of the University's vision.”
