Intellectual causes for behaviours
Due to the impact dementia has on the brain, there are intellectual impairments that individuals with dementia deal with that can cause agitation or other behaviours. Healthcare professionals refer to them as the Seven A’s which help explain the frustration a patient faces:
1. Anosognosia is the lack of insight or awareness. The person with dementia does not know they have dementia and they believe they are fine. “There’s nothing wrong with me.”
2. Amnesia is the loss of memories such as facts, experiences or information. The patient may know who they are but has trouble learning new information or forming new memories.
3. Altered Perception is the inability to recognize themselves – their own reflection. Living in the past – living 25 years in the past becomes their reality.
4. Aphasia is a problem with language. There are four kinds:
Expressive: know what you want to say but can’t say what you mean
Receptive: hear the voice or see the print but can’t make sense of the words
Anomic: trouble using the correct word for places, object or events
Global: can’t speak, understand speech, read or write
5. Apathy is the absence or suppression of interest or motivation.

6. Agnosia is the loss of the ability to recognize objects, faces, voices or places, but still have an ability to think, speak and interact with the world normally.
7. Apraxia is a motor speech disorder where messages from the brain to the mouth are disrupted. The person is unable to move their mouth, lips or tongue to the right place to make sounds correctly even though their muscles are not weak.
