Understanding Anger In Elderly Stroke Patients

Stroke survivors often experience a range of emotional and behavioural changes, including anger. In fact, studies have shown that between 11-35% of stroke survivors experience anger or aggressive behaviours during the acute stage of stroke, while 19-32% experience anger during the first 3-12 months following a stroke. This can be distressing for both the survivor and their loved ones. There are many reasons why stroke patients may become angry, including changes in emotional regulation due to altered brain chemistry or damage to specific areas of the brain, as well as unwanted lifestyle changes.

Emotional regulation changes due to altered brain chemistry or damage to specific brain areas

Emotional regulation changes after a stroke can be caused by altered brain chemistry or damage to specific areas of the brain. This can lead to anger and aggressive behaviour in patients.

The brain plays a crucial role in controlling our behaviour and emotions. When the brain is affected by a stroke, it can impact a person's ability to regulate their emotions, leading to anger and aggressive outbursts. These emotional changes can be a result of alterations in brain chemistry or damage to specific brain regions.

Altered brain chemistry after a stroke can disrupt the brain's serotonin system, increasing the prevalence of angry or aggressive behaviour. Serotonin is a neurotransmitter that carries signals between neurons in the brain. Disruption of this system can lead to an imbalance in serotonin levels, affecting mood and emotional regulation. This can result in anger and aggression.

Additionally, damage to specific areas of the brain can also contribute to emotional regulation changes. The frontal lobe, in particular, plays a significant role in reasoning, problem-solving, and controlling basic impulses like anger. When the frontal lobe is damaged, it can affect emotional regulation, leading to aggressive behaviour. Other brain areas, such as the lenticulocapsular and pontine base regions, are also implicated in emotional control. Damage to these areas can lead to emotional incontinence, or the inability to control emotions, including anger.

The combination of altered brain chemistry and damage to specific brain regions can have a significant impact on emotional regulation, leading to anger and aggression in stroke patients. These changes can be temporary or long-lasting, depending on the severity and location of the brain injury. Understanding the underlying causes of emotional regulation changes is crucial for developing effective treatment strategies and managing the behavioural and emotional challenges that stroke patients may face during their recovery.

Unwanted lifestyle changes, such as losing their job due to stroke-related impairments

Losing their job due to stroke-related impairments can be a significant source of anger for elderly stroke patients, leading to unwanted lifestyle changes and financial difficulties. This is especially true if the patient was the primary breadwinner or had a strong attachment to their career. The loss of income and change in financial status can cause stress, anxiety, and depression, which may manifest as anger or aggressive behaviour.

The impact of job loss on stroke patients is not just financial; it can also affect their sense of identity, self-worth, and social status. Work often provides a sense of purpose, structure, and routine to people's lives, and losing that can be devastating, leading to feelings of loss, isolation, and depression. These emotional and psychological effects can be exacerbated by the physical and cognitive challenges that often accompany stroke, such as motor impairments, pain, and difficulty speaking or understanding others.

Additionally, stroke survivors may struggle to find new employment due to their impairments, which can further contribute to their anger and frustration. They may face discrimination or be unable to perform the same tasks as before, leading to a sense of helplessness and frustration.

It is important to recognise that the anger and aggression exhibited by stroke patients is often a symptom of brain injury and the resulting emotional dysregulation, rather than a conscious choice. The frontal lobe, in particular, plays a crucial role in impulse control and emotional regulation. Damage to this area can lead to aggressive behaviour and anger, as the patient may be unable to control their emotions effectively.

To help stroke patients deal with these unwanted lifestyle changes and resulting anger, a multidisciplinary approach is necessary. This may include psychological counselling or therapy to help them process their emotions and adjust to their new reality. Additionally, vocational rehabilitation services can assist in finding suitable employment or retraining for new careers. Social support and understanding from family, friends, and caregivers are also crucial in helping stroke patients cope with these changes.

Furthermore, employers can play a pivotal role in helping stroke survivors return to work by providing accommodations and understanding the impairments related to stroke. This may include offering shorter hours, remote work, or a gradual return to duties. By providing these accommodations and creating an inclusive work environment, employers can help reduce the financial and emotional burden on stroke survivors, potentially reducing their anger and improving their quality of life.

Cognitive changes that alter their ability to process information and understand others

Anger after a stroke can be caused by a combination of factors, including cognitive changes that alter the patient's ability to process information and understand others. These changes can result in a lack of empathy and increased impulsivity, leading to frequent feelings of anger.

The brain controls our behaviour and emotions, and when it is impacted by a stroke, it can cause a range of emotional and behavioural changes. Cognitive changes are one of the sources of these emotional changes, and they can affect the way a person processes information and understands their surroundings.

Cognitive impairments can make it difficult for stroke survivors to perform daily tasks and adapt to new neurological deficits, leading to feelings of frustration and anger. They may struggle with activities that were once second nature to them, and this difficulty in performing familiar tasks can be a significant trigger for anger.

In addition, cognitive changes can also affect a person's ability to understand and process social cues, leading to misinterpretations of other people's actions. This can result in feelings of anger or aggression towards family members and caregivers, who may unintentionally trigger the patient by asking them to do something they find difficult.

Furthermore, cognitive impairments can also affect a person's ability to regulate their emotions effectively. This can lead to emotional outbursts, including anger, that may seem disproportionate to the situation. The patient may not be able to control their anger or understand why they are feeling angry, which can be distressing for both the patient and their loved ones.

It is important to recognise that these cognitive changes are a result of the brain injury caused by the stroke and are not a reflection of the patient's true personality. Understanding the underlying causes of anger after a stroke can help caregivers and family members provide the necessary support and compassion to the patient.

Physical challenges that make it difficult to perform daily tasks

Elderly stroke patients can experience a range of physical challenges that impact their ability to perform daily tasks. These challenges can include motor impairments and pain, which are common secondary effects of a stroke. This can make it difficult for them to engage in basic self-care activities, work, or leisure activities that were once easy for them. For example, they may have difficulty with tasks such as bathing or dressing, or participating in hobbies they once enjoyed. This struggle to perform familiar tasks can lead to feelings of frustration and anger.

In addition to motor impairments, stroke survivors may also experience challenges with their balance and coordination. They might find it hard to walk or maintain their posture, which can make everyday activities more difficult and increase their risk of falling. This reduced mobility can further contribute to feelings of anger and frustration.

Another physical challenge that can impact daily tasks is sensory impairment. Some stroke survivors may experience changes in their vision or hearing, making it difficult to navigate their environment and perform tasks that require visual or auditory input. This can include reading, watching television, or even having a conversation. The inability to engage in these activities as they once did can lead to anger and irritability.

Furthermore, stroke survivors may also face challenges with their speech and language abilities. They might have difficulty expressing their thoughts and needs, which can be frustrating and impact their ability to communicate effectively with others. This difficulty in communication can contribute to feelings of anger, especially if they feel misunderstood or unable to advocate for themselves.

It is important to recognize that these physical challenges can vary widely in their severity and impact on the individual. Some stroke survivors may experience only mild impairments, while others may have more significant disabilities that require long-term rehabilitation and assistance. Nonetheless, the struggle to adapt to these physical challenges can be a significant source of anger and frustration for elderly stroke patients.

Emotional disorders, such as pseudobulbar affect, which can cause involuntary and uncontrollable outbursts of emotion

Pseudobulbar Affect (PBA), or emotional incontinence, is a type of neurological disorder characterised by uncontrollable episodes of crying, laughing, or anger. PBA occurs secondary to a neurologic disorder or brain injury, such as a stroke.

The cardinal feature of PBA is a pathologically lowered threshold for exhibiting the behavioural response of laughter, crying, or anger. An affected individual may experience episodes of these emotions without an apparent motivating stimulus or in response to stimuli that would not typically elicit such a response. For example, a patient may laugh uncontrollably when angry or frustrated. The episodes may also switch between emotional states, resulting in the patient crying uncontrollably before dissolving into fits of laughter.

The onset of PBA can be sudden and unpredictable and has been described by some patients as coming on like a seizure. The outbursts typically last from a few seconds to several minutes and may happen several times a day.

PBA is thought to result from disruptions to the neurological pathways that regulate emotional expression. PBA is most commonly observed in people with neurological injuries such as traumatic brain injury (TBI) and stroke. PBA has also been observed in people with neurological diseases such as:

• Alzheimer's disease
• Attention deficit hyperactivity disorder (ADHD)
• Multiple sclerosis (MS)
• Amyotrophic lateral sclerosis (ALS)
• Parkinson's disease (PD)

PBA is often misdiagnosed as a mood disorder, particularly depression or bipolar disorder. However, there are clear distinctions between PBA and these disorders. In depressive and bipolar disorders, crying, anger, or laughter are typically indicative of mood, whereas the pathological displays of crying which occur in PBA are often in contrast to the underlying mood or greatly in excess of the mood or eliciting stimulus.

While PBA has no cure, certain medications can help manage it. Antidepressants, such as tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs) and norepinephrine/serotonin reuptake inhibitors may help manage the symptoms of PBA. The doses are typically lower than those required to treat depression.
