What is Delirium and Its Main Types

Delirium is an alteration in the mental state that distorts the perception of reality. It can occur suddenly and manifest in various forms. Let’s better understand the main types of delirium and how each presents itself.

Persecutory Delirium (or Paranoia)

This type of delirium makes the person wrongly believe they are being persecuted or that someone is trying to harm them. For example, the person may think they are being poisoned or watched. This causes intense distrust and fear, potentially leading to defensive behaviors.

Grandiose Delirium

Here, the individual has an exaggerated belief about their importance, power, or identity. They may believe they have extraordinary abilities, like superpowers, or that they are a historical or famous figure, like a king or president. This type of delirium often leads to haughty behavior and disdain for others.

Delirium of Reference

Those suffering from this delirium believe that common events or objects have a special meaning directed at them. For example, a person may think a television commercial is speaking directly to them or that all conversations around them are about them.

Jealous Delirium

In this case, the person has an unfounded conviction that they are being betrayed by their partner. They may interpret any common behavior as proof of infidelity. This type of delirium can generate severe conflicts and even domestic violence.

Delirium of Control or Influence

In this type, the individual feels that their thoughts, feelings, or actions are being controlled by external forces. They may believe these influences come from people, groups, or even radiation or machines. This perception of lack of control can be extremely disturbing.

Besides these main types, there are others like erotomanic delirium, where the individual believes a famous person is in love with them, or somatic delirium, which involves beliefs about altered bodily sensations. There are also cases of mixed deliriums, where more than one type presents simultaneously.

Delirium can occur in various situations, from psychiatric illnesses to drug withdrawal or the use of certain medications. To correctly identify and treat it, medical follow-up is essential. Understanding the types of delirium and their manifestations helps seek appropriate treatment and provide necessary support for those suffering from this condition.

Common Causes of Delirium

Delirium can be triggered by a variety of causes, including physical, emotional, and environmental factors. Many of these causes can interact, increasing the complexity of diagnosis and treatment. Let’s explore these causes and understand how they relate.

Physical Factors

Acute or chronic illnesses often trigger delirium. Conditions like severe infections, high fever, dehydration, and metabolic problems are commonly associated with the onset of delirious states. For example, sepsis, a widespread infection, can cause inflammation in the brain, leading to delirium. According to the MSD Manual on Delirium, about 30% of patients with severe infections may experience delirium.

Another important physical factor is substance use and abuse. Medications like sedatives, opioid analgesics, and even alcohol can induce delirium, especially in high doses or when withdrawn abruptly. Some neurological disorders, such as Alzheimer’s and Parkinson’s, also have a high correlation with delirium episodes, worsening the cognitive condition of affected patients.

Emotional Factors

Emotional factors may not be as easily identifiable, but they play a crucial role in the development of delirium. Intense emotional stress, psychological trauma, and the loss of loved ones can trigger a delirious state, especially in vulnerable individuals. In the elderly, anxiety and depression are often associated with the development of delirium, especially in hospital environments, where routine changes and lack of familiarity can exacerbate these feelings.

Environmental Factors

The environment is also a determining factor. Hospital environments, especially intensive care units (ICUs), have high rates of delirium among patients. This is due to several factors, such as inadequate lighting, lack of temporal orientation (e.g., absence of windows showing day and night), and social isolation. Alterations in the sleep-wake cycle are also significant contributors. A study revealed that about 80% of ICU patients may experience delirium at some point during their stay.

These physical, emotional, and environmental factors do not act in isolation. In many cases, they interact in complex ways. For example, an elderly patient with a urinary infection (a physical factor) who is admitted to the ICU (an environmental factor) and has a history of anxiety (an emotional factor) has a significantly high likelihood of developing delirium. Understanding how these factors interact is essential for the prevention and effective management of delirium.

Symptoms and Diagnosis of Delirium

Delirium is a syndrome characterized by an acute and fluctuating alteration of the mental state, primarily affecting the individual’s consciousness and attention. Identifying delirium can be challenging due to the variable nature of symptoms, which can manifest differently throughout the day.

Main Symptoms of Delirium:

• Alteration in Attention: Difficulty in focusing, maintaining, or redirecting attention.
• Disorientation: Confusion regarding time, place, or identity.
• Alterations in Perception: Visual or auditory hallucinations are common.
• Irregular Speech: Incoherent speech and difficulty in communicating clearly.
• Alterations in Sleep-Wake Cycle: Insomnia or excessive sleepiness during the day.

Secondary Symptoms of Delirium:

• Agitation or Lethargy: Hyperactive behavior or, conversely, a significant decrease in activity.
• Emotional Changes: Anxiety, fear, or exaggerated irritability.
• Short-Term Memory Loss: Difficulty remembering recent events.
• Apathetic Behavior: Lack of interest in activities previously considered enjoyable.

For the confirmation of delirium diagnosis, health professionals use a combination of clinical evaluations and complementary exams.

Diagnostic Methods:

• Clinical Evaluation: The initial diagnosis is often made through clinical observation, including detailed questions about the patient’s medical history and possible exposure to triggering factors.
• Assessment Scales: Scales like the CAM (Confusion Assessment Method) are widely used to help identify the presence and severity of delirium.
• Laboratory Tests: Blood and urine tests may be necessary to identify underlying causes such as infections or metabolic imbalances.
• Brain Imaging: Imaging exams like computed tomography (CT) or magnetic resonance imaging (MRI) may be requested to rule out other neurological conditions.

Early diagnosis of delirium is crucial for effective treatment. Identifying symptoms and using appropriate diagnostic methods allow health professionals to provide the necessary care, significantly improving the patient’s quality of life.

Therapeutic Approaches for Delirium

The treatment of delirium is a complex process that combines various therapeutic approaches to ensure patient recovery and well-being. Below, we explore some of the main interventions used, both medical and non-medical, as well as the importance of an interdisciplinary approach in managing this disorder.

Medical Interventions

Medical treatments for delirium usually begin with the identification and correction of underlying causes, such as infections, metabolic imbalances, or medication complications. Once the cause is treated, the therapeutic approach may include the use of antipsychotic medications to control acute symptoms like agitation and hallucinations. It is essential that the use of these medications is monitored by qualified health professionals to avoid possible side effects and ensure patient safety.

Non-Medical Interventions

Equally important as medical interventions are non-medical approaches. These include providing a calm and safe environment, with adequate lighting and the presence of family members or caregivers to offer guidance and emotional support. Temporal orientation, such as reminding the patient of the day and time, as well as ensuring a regular routine, can help reduce confusion and disorientation.

Occupational and rehabilitation therapies also play a significant role in the patient’s recovery. Activities that stimulate cognition and motor skills help keep patients engaged and improve their functional abilities.

Scientific Hypnosis

A complementary approach that has shown effectiveness in managing stress and anxiety associated with delirium is scientific hypnosis. This practice, when conducted by duly qualified professionals, can help patients achieve a deep state of relaxation and improve their ability to cope with stressful situations. The Brazilian Society of Hypnosis offers evidence-based training and postgraduate courses in hypnosis, ensuring that professionals are prepared to apply these techniques effectively and ethically.

Importance of Interdisciplinary Treatment

The treatment of delirium can rarely be successful with a single approach. Collaboration between doctors, nurses, occupational therapists, psychologists, and other health professionals is crucial to provide comprehensive care. This interdisciplinary approach ensures that all patient needs are met, from medical aspects to emotional and physical support.

In summary, effective management of delirium requires a combination of medical and non-medical interventions, with the inclusion of complementary methodologies like scientific hypnosis. The key to success lies in coordination between various areas of knowledge, ensuring comprehensive and effective care for patients.

Conclusion

In summary, delirium is a complex mental condition that requires a multidisciplinary approach for its effective management and treatment. Early identification of symptoms and causes, along with an accurate diagnosis, are fundamental steps to initiate appropriate treatment.

Within an ethical and scientific approach, hypnosis can be an effective complementary tool in controlling stress and anxiety, both factors that can aggravate the delirium condition. The Brazilian Society of Hypnosis is dedicated to promoting the responsible use of hypnosis, always aligned with recognized medical guidelines.

It is essential that health professionals are well-informed about the best practices and methods for treating delirium, ensuring comprehensive and humanized care for patients. Commitment to evidence-based methodologies makes treatment safer and more effective.
