At the age of sixty-nine Nigel Murray, a retired university lecturer and former Army officer, was diagnosed with dementia.
Doctors suspected he was suffering from a rare and degenerative neurological disorder known as Multiple System Atrophy (MSA).
However, Nigel also had many of the symptoms of both Parkinson's disease and Lewy Body dementia and an official diagnosis was never made.
For four years Nigel's wife, Eileen, kept a diary.
This was her safety valve - an outlet for the daily.
