Easing dementia's
hardest hours so families
can stay together.
Sundowning is the deeply challenging symptom affecting 66% of those living with dementia or Alzheimer's, when anxiety, confusion, and restlessness often increase as daylight fades. For countless families, it becomes the tipping point: an unbearable source of stress and exhaustion that too often forces an early move into residential care. At Glow Therapeutics, we focus on easing these hardest hours, restoring calm and reducing that pressure, so families can stay together at home for longer.
