I am realising the debt I owe to K from Dementia Engagement this morning.  She taught me that the Emotional Memory remains intact even when dementia is at full throttle.  I will be eternally grateful for her exposition on the Dementia Friends Course where she likened it all to two filing cabinets.  One with the day to day short term memories is often firmly shut.  The other containing emotional memories is still accessible even when the condition is in its later stages.  How else would I make sense of the vivid recollection my wife has of  last night?
