A recent study has raised concerns about the long-term effects of growth hormone injections derived from cadavers, suggesting a potential link to Alzheimer’s disease. The practice, which was prevalent during 1959–1985 to treat short stature in children, has been associated with the development of Creutzfeldt-Jakob disease, a fatal brain condition caused by misfolded prion proteins.
Researchers, led by neurologist John Collinge from the University College London Institute of Prion Diseases, investigated the cognitive health of individuals who received these now-banned injections as children but did not die from Creutzfeldt-Jakob disease. Shockingly, five out of eight individuals developed symptoms consistent with Alzheimer’s disease in their 30s, 40s, and 50s.
The study’s findings suggest a potential transmission of Alzheimer’s disease through these growth hormone injections, shedding light on the risks associated with such medical procedures. Importantly, the presence of Alzheimer’s biomarkers and brain atrophy in the cohort further supports this hypothesis, indicating a possible link between the injections and the development of the disease.
The research underscores the need for stringent decontamination protocols in neurosurgery to prevent the transmission of Alzheimer’s proteins between patients. Standard sanitization techniques may not effectively remove prions, emphasizing the importance of implementing comprehensive sterilization measures to safeguard patient safety.
Moreover, the study’s implications extend to our understanding of Alzheimer’s disease pathogenesis, suggesting a prion-like mechanism wherein degenerate proteins trigger a chain reaction in the brain. This paradigm shift could have significant implications for therapeutic strategies aimed at combating Alzheimer’s disease and related neurodegenerative conditions.
As further research delves into the mechanisms underlying Alzheimer’s disease transmission and pathogenesis, it is crucial to prioritize patient safety and adopt preventive measures to mitigate the risk of disease transmission in medical settings.
