Functional Seizures 101: Current Understandings and Treatments

Seizures, a disruption of normal brain activity, come in various forms, each with its own characteristics and underlying causes. Among them, functional seizures stand out for their complexity and sometimes perplexing nature. Let's explore their classifications, from epileptic to non-epileptic, and the treatment options available for functional seizures.

Classifying Seizures: Epileptic vs. Non-Epileptic

Seizures can be broadly classified into two categories: epileptic and non-epileptic. Understanding the differences between these classifications is crucial for accurate diagnosis and appropriate treatment.


Epileptic Seizures: Epileptic seizures are caused by abnormal electrical activity in the brain and are typically associated with epilepsy, a neurological disorder characterized by recurrent seizures. These seizures often have a specific trigger and can be further categorized into various types, including focal onset, generalized onset, and unknown onset seizures. Focal onset seizures originate in one area of the brain, while generalized onset seizures involve both hemispheres of the brain from the onset. Unknown onset seizures are those whose point of origin cannot be determined with certainty.


Non-Epileptic Seizures (NES): Non-epileptic seizures, also known as psychogenic non-epileptic seizures (PNES) or functional seizures, are not caused by abnormal electrical activity in the brain but rather by psychological factors. These seizures may resemble epileptic seizures in their outward manifestations, making diagnosis challenging. However, they are distinct in their underlying causes and require a different approach to treatment.


Names for Non-Epileptic Seizures:

  1. Psychogenic non-epileptic seizures (PNES)

  2. Functional seizures

  3. Dissociative seizures

To provide a clearer understanding of the differences between epileptic and non-epileptic seizures, let's explore the key factors that distinguish these two types.

Treatment Options for Functional Seizures

Treatment for functional seizures often involves a multidisciplinary approach aimed at addressing underlying psychological factors and improving overall well-being. Here are some of the treatment options currently available:


  1. Psychotherapy: Cognitive-behavioral therapy (CBT) and psychotherapy are often used to help individuals identify and cope with stressors or trauma that may trigger seizures. These therapies can also assist in managing anxiety and other psychological symptoms.

  2. Medication: While traditional epilepsy medications may not be effective for functional seizures, psychiatric medications such as antidepressants or anti-anxiety medications may be prescribed to manage underlying psychological conditions.

  3. Stress Management Techniques: Stress-reduction techniques such as mindfulness meditation, relaxation exercises, and stress management training can help individuals reduce their overall stress levels and decrease the likelihood of seizures.

  4. Education and Support: Education about functional seizures and support from healthcare professionals, support groups, and peers can empower individuals to better understand and manage their condition.

  5. Lifestyle Changes: Adopting a healthy lifestyle, including regular exercise, adequate sleep, and a balanced diet, can contribute to overall well-being and may help reduce the frequency and severity of seizures.


For more detailed information on the treatment of functional seizures, you can refer to reputable medical sources such as the Mayo Clinic and the National Institute of Neurological Disorders and Stroke.


In conclusion, understanding the classifications of seizures, from epileptic to non-epileptic, is essential for accurate diagnosis and effective treatment. Functional seizures, while distinct from epileptic seizures in their underlying causes, require a comprehensive approach that addresses both psychological and physiological factors. By raising awareness and providing access to appropriate resources and support, we can work together to help individuals with functional seizures lead fulfilling and empowered lives.
