Memories of the Real Helen Carswell
Our Lingering Farewell
Our Lingering Farewell is penned by Dr. Allan Carswell in honour of his wife, Helen Carswell; her charming spirit, extraordinary achievements and contributions, and most of all her courageous journey with Alzheimer’s disease since the late 1990s. Dr Carswell imparts the many poignant experiences he and Helen have shared, their deep love for each other and their family, their positive approach to each day and challenge, and the lessons learned he hopes will help others on a similar path. He also speaks openly about the heavy waves of sadness that weave their way through the quiet moments of today.
