Many wonder if stress can lead to seizures. While stress does not directly cause epilepsy, it can influence seizure activity in various ways. Understanding this connection involves examining the body’s stress response and different seizure-like events.
Understanding Seizures and Stress
A seizure is a sudden, brief disruption of brain activity, characterized by abnormal or excessive neuronal firing. This overload of electrical signals can manifest as changes in movement, sensation, behavior, or awareness. Seizures can vary widely in their presentation, from subtle changes in attention to generalized convulsions.
Stress is the body’s response to any demand or threat, whether environmental, physical, or psychological. It involves physiological and hormonal changes for adaptation. The “fight-or-flight” response, an automatic reaction triggered by perceived danger, releases hormones like adrenaline and cortisol. These prepare the body to confront or evade a threat by increasing heart rate, blood pressure, and alertness.
Stress as a Seizure Trigger
For individuals with epilepsy, stress can influence seizure frequency. Acute or prolonged stress may lower the seizure threshold, increasing susceptibility to epileptic seizures. This effect is partly attributed to cortisol release, a stress hormone with excitatory brain properties. Chronic stress can also lead to imbalances in neurosteroids, which regulate brain inhibition, potentially increasing seizure vulnerability. Stress can also disrupt sleep, a known seizure trigger for many with epilepsy.
Beyond epileptic seizures, stress links to Psychogenic Non-Epileptic Seizures (PNES). These seizure-like episodes resemble epileptic seizures but lack abnormal brain electrical activity. PNES are psychological, often arising as an involuntary physical manifestation of emotional distress or trauma. These events are genuine and not consciously faked.
Many with PNES have underlying psychiatric conditions like anxiety, depression, PTSD, or a history of trauma. Anti-seizure medications, targeting brain electrical activity, are ineffective for PNES because the cause is not neurological.
Recognizing and Addressing Stress-Related Seizures
Distinguishing between epileptic seizures and PNES is important for appropriate management, as their causes and treatments differ. Video-EEG monitoring is considered the most reliable diagnostic tool. This process involves continuous video recording alongside an electroencephalogram (EEG) to capture both the physical manifestations of an event and the brain’s electrical activity. During a PNES event, the EEG will show normal brain electrical activity, whereas an epileptic seizure will reveal abnormal electrical discharges. Clinical observations, such as prolonged duration of events, eyes often being closed during the episode, and the absence of post-seizure confusion, can also suggest PNES.
Managing stress is an important component of seizure control for both types of events. For individuals with epilepsy, reducing stress through lifestyle adjustments can help to minimize triggers. This includes maintaining a consistent sleep schedule, engaging in regular physical activity, and adhering to a balanced diet.
For those experiencing PNES, treatment focuses on addressing the underlying psychological distress. Cognitive Behavioral Therapy (CBT) is an effective psychological intervention, helping individuals understand and manage their triggers and develop coping strategies. Other approaches like mindfulness and relaxation techniques can also be beneficial in reducing overall stress levels. Seeking professional guidance from neurologists and mental health specialists is recommended for accurate diagnosis and a tailored treatment plan.
