Dementia
                                 Changes and Challenges
          times it was after long flights. It is interesting that some aspects/abnormalities
          of sleep have been linked with Dementia. The nature of that link is highly
          debatable as yet, but it is something to consider.

          Another interesting observation is that the busier I am doing something
          meaningful, the better the quality of sleep. My most exhausting days are
          those days where I have nothing to do. Not only are they draining, but sleep
          quality is minimal. Contrast this to a day where I am busy, either carrying out a
          meaningful task at home, or traveling and speaking publicly about my
          experiences. I would be active for far more hours in the day, not feel
          exhausted and have better quality sleep.
          The hard thing is that Dementia robs me of much of the choice of the type of
          day I can have.


          To Make Sense, It’s Not Just One Sense!
          Most people when given the granular list of 20 or so senses are initially
          sceptical that we could have more than the ‘traditional’ 5 senses. Some
          research groups suggest that the number of individual senses could be near
          30! What I was trying to do with this list, is reflect the increased knowledge
          about brain function and how brain anatomy relates to sensory interpretation.

          We have evolved the ‘most complex’ organ in the known universe to enable
          us to better understand our environment and to interact with others of our
          species.  To this end, our brain does not interpret sensory input in isolation.
          We work with all our senses together to better make sense of our
          environment. Imagine a ‘caveman’ peering into a dark forest. Are those
          stripes he can just make out a potential dinner in the form of a Zebra, or are
          they a Tiger that has him on the menu? Does it sound like a Zebra? Does it
          smell like a Zebra? (If the Zebra was smart it might evolve an odour like a Tiger
          to confuse our caveman). We rely on interpreting our senses together to help
          with our survival.

          Now, let’s take an example out of my experience, food. Take a humble
          chocolate biscuit and separate out our sensory interpretation of it.
