Smell disorder in Alzheimer’s disease

Alzheimer’s dementia, like Parkinson’s disease, belongs to the neurodegenerative diseases. Alzheimer’s disease is characterized by similarly severe olfactory disorders as Parkinson’s disease. As with Parkinson’s disease, they are an early symptom of the disease.

However, an olfactory test alone cannot distinguish between incipient Alzheimer’s or Parkinson’s disease. However, a clear connection between the severity of Alzheimer’s dementia and the severity of the olfactory disorder can be established. Thus, olfactory testing can contribute to the diagnosis as well as predict the prognosis.
