There are seven different stages of dementia, according to the widely used Global Deterioration Scale for Assessment of Primary Degenerative Dementia (GDS). Also known more simply as the Reisberg Scale, the seven stages are based on the amount of cognitive decline.  Stages 1 through 3 would be categorized as no dementia with very mild to no cognitive decline. Stage 4 is considered early dementia, and is usually when a diagnosis has been made. Stages 5 and 6 are middle stage or moderate dementia. And lastly, stage 7 is considered late stage dementia with very severe cognitive decline.  At The Piper, we can be with you through the entire journey of your loved one’s dementia. Some of our residents in stages 1 through 4 may still be suitable for assisted living. Other residents in the middle and late stages may require a higher level of support found in memory care.
