Anger And Strokes: Understanding The Potential Risk

Anger and emotional upset are being investigated as potential triggers for strokes. A global study of 13,462 stroke patients from 32 countries found that about 1 in 11 stroke patients experience anger or emotional upset in the hour before their stroke symptoms begin. The risk of a stroke was about 30% higher in the hour after an episode of anger or emotional upset compared to the same time the day before. Another study found that the risk of a stroke was more than tripled in the two hours after an angry outburst. However, the link between anger and stroke is still being studied, and more research is needed to understand the connection and potential interventions.

Anger and other negative emotions may be triggers for stroke

The study examined 200 people who were hospitalized with an ischemic stroke or a transient ischemic attack (mini-stroke). The participants, who had an average age of 68, were interviewed one to four days after the stroke occurred. Approximately 30% of patients reported exposure to anger or negative emotions such as fear, irritability, or nervousness in the two hours before the stroke. According to the study, exposure to a potential trigger could increase the risk of stroke by as much as 14 times during the two-hour period immediately following exposure.

Another study by Harvard School of Public Health (HSPH), Beth Israel Deaconess Medical Center, and New York-Presbyterian Hospital researchers found that people who have angry outbursts appear to be at increased risk of stroke, especially within the first two hours of an outburst. The researchers reviewed data from nine studies involving thousands of people and found that the risk of stroke more than tripled in the two hours after an outburst.

A large international study published in the European Heart Journal in 2021 also found that about 1 in 11 stroke patients experience anger or emotional upset in the hour before their stroke symptoms begin. The study looked at data from 13,462 patients in 32 countries who had strokes and found that anger or emotional upset was linked to an approximately 30% higher risk of having a stroke within one hour of experiencing those emotions.

While the exact mechanisms are not fully understood, it is believed that brief episodes of mental stress can cause transient changes in blood clotting and blood vessel function, leading to increased risk of stroke. Additionally, sudden reactions to startling events could trigger a stroke through effects on blood circulation or an excessive response by the sympathetic nervous system, which regulates heart rate and blood pressure.

It is important to note that anger and negative emotions are not the only factors that contribute to stroke risk. Other well-known risk factors include high blood pressure, smoking, diabetes, high cholesterol, and obesity. However, understanding the role of emotional triggers can help identify potential interventions and preventive measures to reduce the risk of stroke.

People with cardiovascular disease are at particular risk of stroke after an angry outburst

Anger can indeed trigger a stroke, and people with cardiovascular disease are at particular risk of stroke after an angry outburst. A study by Harvard School of Public Health (HSPH), Beth Israel Deaconess Medical Center, and New York-Presbyterian Hospital researchers found that heart attack risk increased about five times in the two hours after an outburst, and the risk of stroke more than tripled.

The study, which reviewed data from nine studies involving thousands of people, also found that a single angry outburst once a month in someone at low risk for cardiovascular disease was associated with one extra heart attack per 10,000 people annually. The risk increased to four extra heart attacks per 10,0000 people among those at high risk. Furthermore, five angry episodes each day would result in about 158 extra heart attacks per 10,000 people at low risk annually or about 657 extra heart attacks per 10,000 in those at high risk.

The findings suggest that the risk of experiencing an acute cardiovascular event with any single outburst of anger is relatively low, but the risk can accumulate for people with frequent episodes of anger. This is especially true for those with cardiovascular disease, who are at particular risk of stroke after an angry outburst.

While the exact mechanism is not yet fully understood, researchers have proposed several hypotheses to explain the relationship between anger and stroke. One theory suggests that individuals with angry temperaments may have constant physiological activation, particularly sympathetic activation, which can lead to endothelial damage, increased vascular rigidity, and elevated blood pressure. Another hypothesis is that anger results in increased cortisol release along with activation of the hypothalamo-hypophyseal axis, which may result in the disruption of vulnerable plaques, especially in those with other risk factors. Finally, anger may also increase inflammatory and pro-thrombotic responses, leading to increased platelet aggregation, plasma viscosity, and decreased fibrinolytic potential.

It is important to note that the findings do not necessarily indicate that anger is the sole cause of heart and circulatory problems. However, it is a contributing factor, and managing anger may help reduce the risk of stroke, especially in those with cardiovascular disease.

Anger after a stroke can be caused by changes in emotional regulation due to altered brain chemistry or damage to specific brain areas

Anger after a stroke can be caused by changes in emotional regulation due to altered brain chemistry or damage to specific areas of the brain. This can manifest as aggressive behaviours, difficulty getting along with family members, or even domestic violence.

The emotional changes that occur after a stroke can be attributed to various factors, including changes in brain chemistry and damage to specific areas of the brain, such as the fronto-lenticulocapsular-pontine base area. These changes can lead to cognitive and physical effects, such as motor impairments and pain, that make it difficult for individuals to perform daily tasks, resulting in frustration and anger.

Additionally, emotional disorders may develop when a stroke affects the emotion centre of the brain, causing a condition called pseudobulbar affect. This can lead to involuntary and uncontrollable outbursts of anger, even in situations that do not warrant such a response.

Furthermore, genetic predisposition may also play a role in the development of anger after a stroke. Studies have found that certain genetic variations are associated with post-stroke anger, indicating a potential biological basis for this emotional response.

It is important to address anger after a stroke as it can cause distress for both survivors and their loved ones. Recognising and understanding the triggers of anger can help manage and reduce angry feelings. In some cases, pharmacological interventions, such as selective serotonin reuptake inhibitors (SSRIs), may be beneficial in reducing anger and improving quality of life.

Post-stroke anger can cause distress for survivors and their loved ones

Anger after a stroke can be a result of altered brain chemistry or damage to specific areas of the brain. It can also be caused by unwanted lifestyle changes, such as losing a job due to stroke-related impairments. Post-stroke anger can manifest as aggressive behaviours, such as hitting, or as difficulty getting along with family members.

Post-stroke anger can be distressing for both survivors and their loved ones. It can negatively impact a survivor's quality of life and increase the burden on caregivers. It is often episodic and not associated with persistent, inherent psychological problems. However, it can occasionally trouble caregivers and increase their burden, especially when combined with other emotional disturbances like depression.

Post-stroke anger is relatively common, affecting 11-35% of survivors during the acute stage and 19-32% during the first 3-12 months. It tends to gradually decrease over time, but survivors and their loved ones can take proactive steps to manage and reduce angry feelings. This includes recognising and avoiding triggers, taking breaks when frustrated, and practicing self-compassion and anger coping mechanisms like listening to relaxing music or meditation.

Pharmacological interventions, such as selective serotonin reuptake inhibitors (SSRIs), can also be considered if anger is reducing quality of life or damaging relationships. These medications are generally well-tolerated and effective in reducing anger severity. However, they may have side effects like anxiety, confusion, and sleep disturbances, which can trigger anger. Therefore, survivors should work closely with their doctors to monitor their health and adjust their treatment plan as needed.

Loved ones of stroke survivors can also play a vital role in reducing anger by practicing empathy and compassion and not taking angry words and actions personally. Responding gently and compassionately can help survivors feel heard and understood, diffusing angry situations. Additionally, validating survivors' feelings of hurt, frustration, and anger directed at challenging circumstances can be helpful. It is also important for caregivers to practice self-care and maintain healthy boundaries to manage the additional stress that angry outbursts can bring.

Survivors and their families should consider whether anger is a new development or if it has lessened or intensified after a stroke

Anger after a stroke is a common experience, with studies showing that between 11-35% of stroke survivors experience anger or aggression during the acute stage, and 19-32% in the first 3-12 months following a stroke. For survivors and their families, it is important to consider whether this anger is a new symptom, or if it has lessened or intensified after the stroke.

Anger can be a symptom of the stroke itself, as changes in brain chemistry or damage to specific areas of the brain can alter emotional regulation. This can result in a range of emotions, including anger, and can be further influenced by unwanted lifestyle changes, such as job loss due to stroke-related impairments. Additionally, anger can be a risk factor for having a stroke, with studies indicating that acute anger and negative emotions can trigger stroke onset.

For survivors and their families, understanding the triggers and causes of anger after a stroke is crucial. It may be related to cognitive changes, physical effects, or emotional disorders. Cognitive changes, such as lack of empathy or increased impulsivity, can lead to frequent feelings of anger. Physical challenges, such as motor impairments and pain, can make daily tasks difficult and frustrating, triggering anger. Emotional disorders, such as pseudobulbar affect, can cause involuntary and uncontrollable outbursts of anger.

Identifying and managing anger triggers are essential for both survivors and their loved ones. Common triggers include a perceived lack of control, difficulty performing tasks, fatigue, confusion, and overstimulation. Recognizing these triggers can help develop strategies to reduce or avoid them, such as taking breaks, practising self-compassion, and engaging in leisure activities.

In some cases, anger after a stroke may be a pre-existing condition that has been exacerbated by the stroke. Addressing anger issues before a stroke occurs can help reduce the risk of stroke and improve overall well-being. Seeking help from mental health professionals and support groups can be beneficial for managing anger and its underlying causes.

By understanding the causes and triggers of anger, survivors and their families can work together to reduce anger intensity and frequency. This may involve making lifestyle changes, such as avoiding crowded areas, encouraging rest, and celebrating progress. Additionally, medications, such as selective serotonin reuptake inhibitors (SSRIs), can be considered if anger is significantly impacting quality of life and relationships.
