Understanding the Difference Between Pseudo-Seizures and True Seizures

Seizures, whether epileptic or non-epileptic, can be both challenging and confusing to differentiate, especially for those unfamiliar with their symptoms. When trying to understand the difference between pseudo-seizures (alleged seizures) and true seizures, it's crucial to rely on medical expertise and evidence rather than relying on personal judgments. This article provides a comprehensive guide on how to distinguish between the two, emphasizing the importance of professional diagnosis and support.

Introduction to Seizures

A seizure is an abnormal and excessive electrical discharge in the brain, often leading to a temporary disturbance in the person's movement, behavior, and awareness. Seizures can be categorized into two main types: epileptic seizures and non-epileptic seizures (NES), also known historically as pseudo-seizures. An epileptic seizure is the result of an overactive electrical discharge, while NES are caused by psychological or emotional stress. Both types require careful medical evaluation and understanding to ensure appropriate treatment and support.

Understanding Pseudo-Seizures (NES)

Pseudo-seizures, now commonly referred to as non-epileptic seizures (NES), are often the subject of misunderstanding and misjudgment. These occurrences were once thought to be fabricated or a part of deliberate behavior. However, contemporary medical research and clinical observations have clarified that NES are real and involuntary phenomena. They are characterized by a range of physical and psychological symptoms, making them distinct from epileptic seizures.

Real and Involuntary Symptoms

Contrary to the common belief that pseudo-seizures are faked, NES are symptomatic of underlying psychological stress or trauma. These seizures are not under the voluntary control of the individual. The symptoms can include convulsions, muscle spasms, and altered awareness, among others. Unlike epileptic seizures, pseudo-seizures often don't have any electrical activity as evidenced by the absence of abnormal brain waves on an electroencephalogram (EEG).

Understanding True Seizures

True seizures, or epileptic seizures, are caused by abnormal electrical activity in the brain. These seizures are sudden and can be brief or prolonged, depending on the type. Epileptic seizures often involve loss of consciousness, convulsions, and altered behavior. They are generally detected through an EEG, which may show characteristic changes in brain activity.

Differentiating Between Seizure Types

Despite the overlap between pseudo-seizures and true seizures, there are several key differences that can help differentiate between them. For instance, pseudo-seizures may include vocalizations such as screams, which are less common in true seizures. The duration of the seizure is also a significant factor, with pseudo-seizures often lasting longer, sometimes up to 16 hours as noted in some cases.

Additionally, people experiencing pseudo-seizures often remain conscious throughout the event, although this may not always be the case. Muscle spasms and convulsions are common in both types, but pseudo-seizures may include specific physical contortions that are not easily replicated voluntarily. Pain and memory loss can also occur with both types, though the degree and manifestation of these symptoms can differ.

Diagnosing Seizures

Given the overlap between epileptic and non-epileptic seizures, it is vital to seek professional medical help if a seizure occurs. A neurologist can conduct a thorough evaluation, including a detailed medical history, physical examination, and diagnostic tests such as an EEG. These assessments are crucial for accurate diagnosis and appropriate treatment.

Key Points for Diagnosis: History of the seizure: Timing, duration, and context. Medical history: Past medical conditions, medications, and lifestyle. Electroencephalogram (EEG): To detect abnormal brain wave patterns. Video monitoring: To observe the seizure and correlate it with EEG activity. Psychological assessment: To evaluate for underlying emotional or psychological issues.

Case Studies and Insights

A notable case involved a known epileptic individual presenting with apparent seizures during Christmas Day. Despite the patient's history of epilepsy, it was suspected that the seizures were pseudo-seizures. Upon insistence, an EEG was conducted, revealing a normal EEG during the event, indicating the seizure was not epileptic. This case underscores the importance of thorough diagnostic evaluation, especially when there is a history of psychological stress or trauma.

Common Misunderstandings: Assumption of intentional faking: This is a significant misjudgment. NES are involuntary and often occur due to untreated psychological issues. Overemphasis on observable symptoms: While physical symptoms can be indicative, they should not be used as the sole determinant of the seizure type. Underestimation of the complexity: Seizures, whether epileptic or non-epileptic, are complex phenomena that require professional evaluation to understand fully.

Conclusion

Understanding the difference between pseudo-seizures and true seizures is crucial for both medical professionals and the general public. Embracing a non-judgmental and evidence-based approach is essential for proper care and management of individuals affected by seizures. If you or someone you know is experiencing seizures, it is imperative to consult a neurologist for accurate diagnosis and appropriate treatment.

Through education and awareness, we can foster a more compassionate and understanding society that supports those dealing with the challenges of seizures.
