It is still my hot beverage of choice, long after my peers switched to a daily coffee habit. So what does hot chocolate have to do with dementia? Everything and nothing at all. 
Nothing at all? Our lives do not become a compressed, medical version of ourselves when dementia enters the picture. So moments for play, a treat, or a visit from a loved one should never become a line item on the care plan or viewed with a medical lens. It should happen simply because, and enjoyed for the beauty of being in a relationship with a loved one. 
Life is made up of Moments. Dementia does not change this; these moments become more important with dementia. They are moments of joy, sorrow, care, and faith. So make some hot chocolate in your favorite mug, sit down, breathe, and savor the moment.
