Guest/Lumpyhand, I have a song about Alzheimers- or some kind of dementia:

Mists of Time

I remember
I once had a family
And I know that I was happy then
For I can see their bright little faces
But I don't know where or when

            Memories lost in the mists of time
            I don't know much anymore
            The years, the days, the hours
            All run together
            Memories lost in the mists of time

Yesterday
Or was it just this morning?
They gathered 'round my rocking chair
I recall the scent of many candles
But I knew nobody there.


I like Jesse Winchester's 'We'll Never be this Young Again'.
And the new? song: Bed by the Window
