Emotional Instability And Dementia: Unstable Or Normal?

Emotional instability is a common symptom of dementia, and it can manifest in various ways, such as aggression, catastrophic reactions, and changes in intimacy and sexuality. These changes can be very distressing for both the person with dementia and their loved ones. It is important to remember that these behaviours are caused by the illness and are not a reflection of the person's true character.

People with dementia often experience a range of emotions, including grief, loss, anger, shock, fear, and even relief upon receiving a dementia diagnosis. This can be a difficult time for them and their families, and it is crucial to provide support and understanding.

Emotional instability in dementia can be managed through various strategies, including caregiver training, non-pharmacological interventions such as music therapy, and pharmacological interventions such as antipsychotics and antidepressants. However, it is important to carefully weigh the benefits and risks of these interventions and provide person-centred care.

Overall, emotional instability is a normal and expected symptom of dementia, and it requires careful management to ensure the well-being of both the person with dementia and their caregivers.

Emotional instability in dementia can be caused by a loss of emotional control or motivation

People with dementia may have less control over their feelings and how to express them. For example, they may overreact to things, have rapid mood changes, or feel irritable. They may also appear unusually distant or uninterested in things. These changes are often difficult for carers to deal with. It can help to remember that these changes are partly caused by damage to the person's brain. Someone may react more emotionally to a situation than might be expected because of a decline in their ability to think clearly or loss of factual memories.

Behavioural and psychological symptoms of dementia (BPSD) are an integral part of the dementia syndrome. A decline in emotional control or motivation, or a change in social behaviour, manifesting as emotional lability, irritability, apathy, and coarsening of social behaviour have been a part of the diagnostic criteria for dementia. BPSD can manifest in multiple ways, including behavioural, affective, psychotic, and somatic.

BPSD are often the reasons for the first contact with health professionals and hospitalisation. They impact patient functioning and lead to premature transition to structured living environments and institutionalisation. BPSD are a major cause of diminished quality of life for both patients and caregivers.

Dementia may cause people to feel insecure and lose confidence in themselves and their abilities. They may feel they are no longer in control and may not trust their own judgement. They may also experience the effects of stigma and social 'demotion' – not being treated the same way by people – as a result of their diagnosis. Effects on health, financial circumstances, employment status, and relationships with those around them may also have a negative impact on self-esteem.

Emotional instability in dementia can manifest as irritability, apathy, and coarsening of social behaviour

Emotional instability is a common symptom of dementia. People with dementia experience a wide range of emotions, including grief, loss, anger, shock, fear, disbelief, and relief. They may also feel afraid about the future, scared about moments of confusion and forgetfulness, and upset about the impact of their condition on those around them.

In addition to irritability, apathy, and coarsening of social behaviour, emotional instability in dementia can also lead to aggression, both physical and verbal. Aggressive behaviour is usually an expression of anger, fear, or frustration and may be a way for the person to try to get what they want.

Management strategies for emotional instability in dementia include activity and exercise, approaching the person slowly and in full view, and explaining what is going to happen in short, clear statements. It is also important to check if the person's aggressive behaviour is about getting what they want and try to anticipate their needs.

Emotional instability in dementia can be challenging for both the person with dementia and their caregivers. It is important to seek support and advice from a doctor or other healthcare professionals.

Emotional instability in dementia can be caused by damage to the person's brain

Emotional instability is a common symptom of dementia. It can manifest as aggression, catastrophic reactions, and changes in intimacy and sexuality. These changes can be very difficult for caregivers to deal with. However, it is important to remember that these emotional changes are caused by damage to the person's brain.

A person with dementia may experience a decline in their ability to control their feelings and express them in socially acceptable ways. For example, they may overreact to things, have rapid mood changes, or feel irritable. They may also seem unusually distant or uninterested in things. These emotional changes can be caused by a loss of factual memories or a decline in their ability to think clearly.

In addition, strong emotions in people with dementia may be caused by unmet needs. Caregivers should try to identify and meet these needs where possible. It is also important to remember that the person with dementia may be frightened by their own emotional reactions and may need reassurance.

Dementia can also cause changes in a person's confidence and self-esteem. They may feel insecure, lose confidence in their abilities, and feel like they are no longer in control. They may also experience stigma and social 'demotion', being treated differently by those around them due to their diagnosis.

Finally, it is important to note that emotional instability in dementia can have a significant impact on caregivers. It can be very upsetting for caregivers when a loved one behaves in strange or aggressive ways. Caregivers may need support and understanding as they navigate these challenges.

Emotional instability in dementia can be caused by a decline in the ability to think clearly

Emotional instability in dementia

People with dementia experience a range of emotions, including grief, loss, anger, shock, fear, disbelief, relief, and even positive reactions to their diagnosis. They may also experience a decline in their ability to think clearly, which can lead to emotional instability. This can manifest as a lack of control over their feelings and how they express them. For example, they may overreact to things, have rapid mood changes, or feel irritable.

Causes of emotional instability in dementia

The emotional instability experienced by people with dementia can be caused by a combination of biological, psychological, and environmental factors.

Biological factors

Biological factors that can contribute to emotional instability in dementia include changes in brain function and neurotransmitter imbalances. Specifically, volume reductions and decreased metabolism have been observed in brain regions that mediate emotional regulation, self-awareness, and perception. Imbalances in neurotransmitters such as acetylcholine, dopamine, serotonin, and norepinephrine have also been implicated.

Psychological factors

Psychological factors that can influence emotional instability in dementia include pre-existing personality traits, such as neuroticism, and pre-existing psychiatric disorders, particularly those involving emotional dysregulation, such as post-traumatic stress disorder.

Environmental factors

Environmental factors that can trigger or exacerbate emotional instability in people with dementia include sensory overstimulation or understimulation, uncomfortable physical symptoms (e.g., pain, constipation, urinary retention), and problematic caregiver communication styles.

Management of emotional instability in dementia

The management of emotional instability in dementia involves a multidisciplinary approach, including non-pharmacological and pharmacological interventions.

Non-pharmacological interventions

Non-pharmacological interventions are typically the first-line approach and may include caregiver training, environmental modifications, social interactions, and behavioral interventions. Caregiver training focuses on understanding and responding to behavioral disturbances and creating a soothing environment. Environmental modifications may include adjusting lighting, reducing noise, and providing clear and repetitive instructions. Social interactions and behavioral interventions, such as music therapy and massage, can also help reduce emotional instability.

Pharmacological interventions

Pharmacological interventions are generally reserved for more severe cases of emotional instability when non-pharmacological interventions have been ineffective. Antipsychotics, such as risperidone and olanzapine, are commonly used to treat agitation and aggression, while antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), may be used to target depression and apathy. It is important to carefully weigh the benefits against the risks of adverse effects when considering pharmacological interventions.

Emotional instability in dementia can be caused by a loss of factual memories

The loss of factual memories can have a significant impact on the emotions of both the person with dementia and their loved ones. For the person with dementia, it can cause frustration, embarrassment, and a loss of self-confidence. They may withdraw from social situations and stop doing things they usually enjoy. Memory loss can also lead to anger and mistrust, as the person may accuse others of moving or stealing misplaced items.

For caregivers and loved ones, it can be challenging and upsetting to witness the person with dementia struggling with memory loss. They may feel embarrassed when the person forgets who someone is or is no longer able to perform familiar tasks. It can also be tiring and frustrating to be asked the same question repeatedly, leading to feelings of guilt.

Additionally, the loss of factual memories can contribute to other behavioural changes associated with dementia. For example, a person with dementia may overreact to situations or experience rapid mood changes due to their inability to think clearly or recall factual information.

It is important for caregivers to recognise and respond to the emotional needs of the person with dementia. This includes providing support, encouragement, and praise, as well as helping them to continue participating in meaningful activities and social interactions.
