Today, let’s delve into the intricate relationship between Alzheimer’s disease and viral and fungal infections. Recent articles have sparked interest, suggesting that common viruses, including the notorious COVID-19, might play a significant role in the development of Alzheimer’s.
The Viral Link
Beyond aging, viral infections emerge as contributing factors to Alzheimer’s disease. Emerging evidence indicates a collaboration between Alzheimer’s and COVID-19, intensifying concerns among experts about potential surges in Alzheimer’s diagnoses.
Researchers highlight a substantial increase in the risk of dementia in older individuals with viral infections. Dr. Thomas E. Lane, a microbiology and immunology expert, anticipates that ongoing research will further solidify the link between microbial infections and neurodegenerative diseases like Alzheimer’s.
Post-COVID, there’s a growing worry about the strain on long-term care resources due to an uptick in Alzheimer’s diagnoses. Dr. Pamela Davis, a distinguished professor, emphasizes the importance of monitoring the long-term consequences of COVID-19, underlining its impact on future disability.
In a retrospective study of over 6.2 million people aged 65 and older, a 69% increased risk of Alzheimer’s diagnosis was observed within a year of COVID-19 infection. This risk was particularly pronounced in women and those over 85. However, COVID-19 isn’t the sole virus linked to Alzheimer’s.
Dr. Nikhil Palekar, director of the Stony Brook Center of Excellence for Alzheimer’s Disease, suggests that viruses like influenza, herpes, and COVID-19 can lead to the accumulation of amyloid proteins in the brain, a core feature of Alzheimer’s pathology.
The Fungal Connection
Shifting focus, a study at Baylor College of Medicine uncovered a connection between fungal infections and Alzheimer’s. The research team investigated Candida albicans, a common fungus found in various human body parts.
Candida Albicans: A Culprit
Animal models revealed that Candida albicans could enter the brain, generate amyloid proteins, and damage the brain, akin to viral infections. Dr. David Corry, a study author, explains that this fungus produces enzymes breaking down the blood-brain barrier, causing brain damage resembling Alzheimer’s.
Studies, including one in Frontiers in Immunology, suggest the role of fungi in central nervous system disorders. Therapeutic strategies targeting fungal infections might offer future breakthroughs.
A 2015 study even found fungal cells in the central nervous systems of Alzheimer’s patients, absent in healthy individuals. These findings hint at intriguing evidence of fungal infections in Alzheimer’s.
The emerging links between viral infections, fungal infections, and Alzheimer’s demand continuous exploration. Understanding these connections is crucial for developing effective treatments and preventive measures.
