The Global Deterioration Scale (GDS) is a 7-point scale used to assess the cognitive decline in individuals with dementia. Understanding this scale can help caregivers adjust their expectations, communication strategies, and care approaches based on the person’s cognitive status. This fact sheet summarizes the stages of dementia, their impact on communication, and practical tips for caregivers.
