Alzheimer’s disease and cognitive impairment problems are going to cause a wide range of different consequences for a lot of people, since the brain is the seat of all functions. Apparently, these kinds of impairments can also potentially weaken a person’s sensory perception. This video demonstrates that certain study participants were less likely to perceive the scent of peanut butter through at least one nostril if they had early-onset Alzheimer’s disease.
This experiment certainly needs to be replicated, but it does manage to raise some interesting questions about the nature of cognitive impairment disorders in the first place. Many of these conditions can have interesting consequences, which can be useful for diagnostics.
People should please SHARE this video on Facebook, since it is certainly interesting to watch, and it might raise some questions about the nature of scientific research and the fact that cognitive impairments can manifest themselves in different ways.
