What’s the Difference Between Aphasia and Dementia
Aphasia and Dementia?

Degenerative brain illnesses that impair cognition are referred to as dementia. Aphasia describes verbal expression or comprehension problems brought on by brain injury.

Alzheimer's disease is one of many degenerative disorders affecting the brain that fall under the general term "dementia." Memory loss, confusion, and personality changes are all common signs of dementia.

Reading, writing, and speaking skills are all impacted by aphasia. This is frequently caused by harm to one or more language regions in the brain. Traumatic injury or a stroke may have caused this harm.

Here's a closer look at how dementia and aphasia relate to one another.

The differences between them

Memory, personality, and conduct can all be negatively impacted by dementia symptoms, which can be very broad. In most cases, symptoms develop gradually over time.

Specific language problems are associated with aphasia. People who have this illness have trouble speaking, writing, reading, and comprehending other people's words.

Aphasia can come in a variety of forms. For instance, conduction aphasia causes people to repeat words blind to their meaning. Broca's aphasia causes choppy speech that frequently has a small vocabulary.

A stroke or head injury is the usual trigger for the onset of aphasia symptoms.

Progressive primary aphasia

While aphasia and dementia are separate medical disorders, aphasia can result from dementia in a condition known as primary progressive aphasia (PPA). In contrast to aphasia brought on by a stroke or brain injury, PPA symptoms typically appear more gradually and worsen with time.

Early communication issues may be minimal and restricted to the occasional forgetfulness of the appropriate words. PPA might result in a total lack of communication skills as the condition worsens.


To properly grasp what is going on, it is crucial to inform a healthcare expert of any changes in cognitive function or communication skills.

Your medical history will be gathered, and questions regarding your symptoms will be asked first. Your symptoms may lead them to recommend cognitive testing. Your doctor can learn more about your current memory or communication skills with the aid of these tests.

Seek immediate medical attention, if you haven't already, if you or someone you know is having trouble communicating after a brain injury or suspected stroke. Some varieties of aphasia resolve with regular speech therapy, but prompt treatment is crucial.


Although dementia cannot be cured, some symptoms may be lessened by some drugs. Additionally beneficial is occupational treatment, particularly in the early stages of dementia.

Treatment for aphasia entails addressing the underlying cause, be it a stroke or a head injury. Speech therapy can aid in language recovery during the rehabilitation process. Aphasia patients occasionally recover completely on their own without help, but the majority will continue to have symptoms.

The bottom line

Aphasia entails damage to the parts of the brain directly connected to language, whereas dementia refers to a variety of degenerative disorders affecting the brain.

Although aphasia and dementia are two distinct illnesses, aphasia, namely PPA, can be a sign of dementia.
