Loss of Smell: A Neurological Red Flag
A reduced or lost sense of smell, medically referred to as anosmia, can indicate early onset of neurodegenerative diseases. In both Parkinson’s and Alzheimer’s diseases, olfactory impairment manifests years before motor or cognitive symptoms do.
Additionally, anosmia can also be a sign of nasal polyps, chronic sinusitis, or even brain tumors affecting the olfactory nerves. With the rise of COVID-19, sudden smell loss has become widely recognized as an early warning sign of viral infection.
Chronic Congestion: Indicator of Allergies or Structural Problems
Constant nasal congestion not linked to a cold may be an indication of chronic rhinitis, deviated septum, or nasal polyps. It is possible for allergic rhinitis to cause nasal passage irritation, which, raises the risk of sinus infections, ear infections, and asthma if left untreated.
In some cases, persistent congestion is linked to nasopharyngeal cancer, especially when associated with ear pain, neck lumps, or hearing issues. Early diagnosis is crucial for effective treatment.
