How Does Dementia Influence Emotional Decision Making
Dementia is not just about forgetting things or losing memories. It is a complex condition that affects how the brain works in many different ways. One of the most important but often overlooked effects of dementia is how it changes the way people make decisions, especially decisions that involve emotions. When someone has dementia, their ability to think clearly, manage their feelings, and make good choices becomes increasingly difficult. Understanding how dementia impacts emotional decision making is crucial for families, caregivers, and healthcare providers who work with people living with this condition.
What Exactly Is Dementia
Before we can understand how dementia affects emotional decision making, we need to understand what dementia actually is. Many people think dementia is a single disease, but it is actually a group of symptoms related to cognitive decline. These symptoms include memory loss, language problems, behavior changes, and difficulty with thinking or decision making. [3] More than half of the people who die from a dementia condition have at least three different conditions related to their cognitive impairment. This means that dementia is not one single problem but rather multiple conditions working together to cause these symptoms. [3]
The brain regions that are damaged in dementia vary depending on the type of dementia a person has. However, certain areas of the brain are particularly important for emotional regulation and decision making. The prefrontal cortex, which is responsible for logic, judgment, and impulse control, is often damaged in dementia. [1] The frontal lobes and limbic system, which help regulate emotions, can also be affected. [1] When these areas of the brain are damaged, the way a person processes information, manages stress, and makes decisions changes dramatically.
How Dementia Damages the Brain’s Decision Making System
The brain has several systems that work together to help us make good decisions. One system helps us think logically and consider the consequences of our actions. Another system helps us manage our emotions so that feelings do not overwhelm our thinking. A third system helps us understand what other people are feeling and thinking. When dementia damages these systems, decision making becomes much harder.
Cognitive decline affects mood and emotional responses by altering brain function and impeding information processing, emotion regulation, and stress management. [1] This means that when someone has dementia, their brain cannot process information the way it used to. They may not be able to understand all the information they need to make a good decision. They may not be able to think through the consequences of different choices. They may not be able to manage the emotions that come up when making a difficult decision.
In the early stages of dementia, a person can still feel various emotions, but they struggle with complex ones, which makes them worried and angry. [1] This is because the brain is starting to have trouble processing complicated information and managing difficult feelings at the same time. As dementia progresses to later stages, people become emotionally unstable and their thinking slows down. People make decisions based on their feelings or impulses when they can no longer forecast the future. [1] This means that instead of thinking about what might happen if they make a certain choice, they simply react based on how they feel in the moment.
The Role of Emotional Regulation in Decision Making
Emotional regulation is the ability to manage your feelings so that they do not control your behavior. It is a crucial skill for making good decisions, especially when those decisions involve something important or stressful. When you need to make a medical decision, a financial decision, or a decision about your care, you need to be able to think clearly even if you are feeling scared, sad, or angry.
Dementia progressively impairs emotional regulation and cognitive decision making. [1] This means that as dementia gets worse, people have a harder and harder time managing their emotions and thinking clearly at the same time. Emotional lability in dementia can result from dysfunction in brain regions responsible for regulating emotions, including frontal-subcortical circuits and other neural pathways. [1] However, it is important to understand that emotional problems in dementia are not solely caused by damage to the frontal lobes or limbic system. Other factors, such as confusion, pain, and unmet needs, also contribute. [1]
When someone with dementia is confused, they may feel scared or frustrated. When they are in pain, they may feel angry or irritable. When their needs are not being met, they may feel upset or distressed. All of these feelings can make it even harder for them to make good decisions. A person with dementia might make a decision based on fear or pain rather than on what is actually best for them.
How Personality Affects Emotional Decision Making in Dementia
An interesting finding from research is that preexisting personality traits strongly influence emotional fluctuations in dementia. [1] This means that the way a person was before they developed dementia affects how their emotions change as the disease progresses.
For example, neurotic individuals may experience anxiety and anger as a result of unfavorable emotions. [1] A person who was naturally anxious or worried before developing dementia might become even more anxious and worried as their condition gets worse. On the other hand, a really conscientious or outgoing person might suppress their confusion and dread, but it could manifest as excessive agitation or a catastrophic reaction. [1] This means that someone who was always very responsible or social might try to hide their confusion and fear, but instead of showing sadness or worry, they might become very agitated or have a sudden emotional breakdown.
Behavioral changes in dementia often reflect unmet needs or distress. [1] While personality traits may influence how emotions are expressed, the relationship between traits and specific behaviors is complex. Understanding a person’s personality before they developed dementia can help caregivers and healthcare providers understand why they are behaving in certain ways and what they might need.
Personality Changes and Emotional Decision Making
Beyond how personality traits influence emotional expression, dementia actually changes who the person is and how they feel hugely. [1] This is particularly true in certain types of dementia. Because the frontal lobe is damaged, conditions such as frontotemporal dementia make people emotionally indifferent, behave in ways that are not socially acceptable, and lose any ability to feel empathy. [1] This means that a person with frontotemporal dementia might not care about decisions that would normally matter to them. They might not understand how their decisions affect other people. They might not feel sad or guilty about things that would normally make someone feel that way.
These personality changes have a huge impact on how people make decisions. If someone loses the ability to feel empathy, they might make decisions that hurt other people without understanding or caring that they are doing so. If someone becomes emotionally indifferent, they might not care about their own health or safety. If someone’s judgment becomes impaired, they might make decisions that are not in their best interest.
