Is aphasia the same as dementia?

No. Aphasia and dementia are different. People with aphasia may have difficulty finding the right words or understanding language, but their memory and thinking skills can still be strong. In dementia, memory and judgment usually decline over time. That said, there are some types of dementia, like Primary Progressive Aphasia (PPA), that start with language problems but will progress to other areas of the brain, impacting other functions.
