Semnul timpuriu asociat cu bolile Parkinson și Alzheimer, care poate apărea cu până la 10 ani înaintea primelor simptome

Early signs of neurodegenerative diseases like Parkinson's and Alzheimer's may manifest as olfactory dysfunction, detectable up to ten years before other symptoms. This condition affects a significant percentage of patients and could serve as a potential early indicator for cognitive decline. Training the sense of smell may enhance brain regions associated with memory and cognition. Despite its importance, olfactory testing remains underutilized in clinical practice, although it could complement routine cognitive assessments. Researchers are exploring the relationship between smell loss and cognitive decline, aiming to understand their connection better.
