2. The progression of dementia
Dementia is a progressive condition. This means it will get worse over time because of damage to the person’s brain, and this will have a big impact on the person’s mental abilities (including memory and communication).
The speed at which dementia worsens varies widely. There are some differences between the different types of dementia – Alzheimer’s disease, for example, seems to have the slowest progression on average. There is also variation from person to person.
