The executive control center of the brain, the prefrontal cortex and the parietal lobe are responsible for behaviors, problem solving and sense of smell.

Decreased sense of smell may indicate early dementia. Loss of sense of smell may indicate onset of some types of dementia, researchers say. Previous research has associated olfactory loss, or anosmia, with cognitive decline, mild cognitive impairment (MCI) or Alzheimer’s disease (AD).

Loss of sense of taste can indicate onset of Parkinson’s.
