Changing Emotions
Dear Caregivers,
To understand how Alzheimer's disease impacts your loved one’s emotions, it is important to keep in mind that Alzheimer’s disease can affect different parts of the brain in different ways. This imbalance contributes to the common emotional symptoms associated with Alzheimer’s, which include depression, apathy, anxiety, fear, and agitation.
A person’s emotions are "housed" in two areas in the brain called the frontal lobe and the amygdala.
The frontal lobe is the main control center for the brain’s emotional control. Even in its earliest stages, Alzheimer’s disease can damage this specific part of the brain, resulting in your loved one having difficulty controlling their emotional responses.
At the same time as this emotional control center is faltering, however, the other key area of the brain for emotions, the amygdala, is often spared from the effects of Alzheimer's disease. The result is that in the early to middle stages people suffering from Alzheimer’s are still able to feel a wide range of positive emotions (happiness, joy, love, humor) and negative emotions (fear, anxiety, loneliness), which are part of what is known as a person’s "fight-or-flight" response.
This combination of your loved one retaining their ability to feel fear and anxiety -- but losing their ability to control their emotional response to these feelings -- creates the potential for exaggerated emotions and unexpected upset. What may seem to you to be a calm and low-stress situation may upset your loved one greatly, resulting in some loved ones being irritable or angry (fight), while others may show depression, lethargy, and social isolation (flight.) It is also possible to have a certain emotional response one day and a different reaction to the same situation the next day.
