Pupillary Dilation in an Adolescent With Psychogenic Non-epileptic Seizures: A Case Report

Case Presentation

A 15-year-old female presented to the emergency department after experiencing what appeared to be seizure-like episodes. The episodes began several months prior, characterized by involuntary jerking movements and altered consciousness, which raised initial concerns for a possible neurological disorder. Upon further examination, it was noted that the episodes were not accompanied by the typical neurophysiological markers characteristic of epileptic seizures. This was significant in guiding the diagnostic process.

During the assessment, the patient reported additional symptoms including anxiety and emotional distress, which seemed to coincide with the onset of her episodes. Notably, her pupillary response during the episodes warranted closer examination. In particular, instances of pupillary dilation were observed, which prompted further investigation into the causes behind this autonomic response. An accompanying family history of psychiatric disorders may provide additional context for her symptoms, suggesting a potential psychogenic basis.

In this case, the patient had no prior history of neurological issues or head trauma, making the sudden appearance of these episodes especially puzzling. A detailed neurologic examination revealed no significant findings, which raised questions about the underlying cause. She was subsequently monitored for the duration of her hospital stay, giving health professionals an opportunity to observe her episodes in a controlled environment. This approach led to valuable insights regarding the nature of her symptoms and the relationship between her emotional state and episodes of apparent seizure activity.

The interdisciplinary team encompassing neurologists, psychiatrists, and general practitioners aimed to explore both physiological and psychological dimensions of her condition, recognizing the complexity often associated with psychogenic non-epileptic seizures (PNES).

Diagnostic Process

The diagnostic process for this adolescent female involved a meticulous approach to differentiate between epileptic seizures and psychogenic non-epileptic seizures (PNES). Initially, a thorough clinical assessment was conducted, with a special focus on the patient’s medical history, the nature of her episodes, and any psychological stressors that could contribute to her symptoms.

To begin, an electroencephalogram (EEG) was performed during an episode to evaluate electrical activity in the brain. The EEG findings showed no epileptiform discharges, which are typically present in cases of true epilepsy. Instead, the resulting waveform patterns were consistent with non-epileptic activity. This finding was pivotal in steering the evaluation away from a primary neurological disorder towards a diagnosis involving psychological factors.

Further diagnostic procedures included neuroimaging studies such as magnetic resonance imaging (MRI) and computed tomography (CT) scans of the brain. These imaging techniques aimed to rule out any structural abnormalities, lesions, or other factors that might trigger seizure-like symptoms. Both scans yielded normal results, providing additional evidence against a neurological basis for the episodes.

In conjunction with these physical examinations, the patient underwent a psychiatric evaluation, which revealed significant levels of anxiety and emotional distress linked to her experiences. She expressed feelings of stress related to academic pressures and interpersonal relationships, which could potentially act as triggers for her episodes. The assessment concluded that her psychological state likely played a critical role in the manifestation of her symptoms.

To further elucidate the connection between her emotional state and physical symptoms, a log was created, enabling the tracking of episodes in relation to mood changes and stressful events. The data collected over several days indicated a clear pattern: episodes often occurred during times of heightened anxiety or emotional turmoil. This observation fortified the impression that her pupillary dilation during episodes was not purely physiological but rather a part of an integrated stress response.

Collaboration among specialists was vital in this diagnostic journey. By integrating insights from neurology and psychiatry, a comprehensive understanding of the patient’s condition emerged, emphasizing the psychosomatic interactions influencing her episodes. The interdisciplinary team developed a nuanced perspective, recognizing that while the episodes presented with physical symptoms, their root cause resided in emotional and psychological distress.

The combination of electrophysiological and psychological assessments eventually paved the way for a diagnosis of PNES. This understanding led to formulating a tailored treatment plan that aimed to address both the psychological components and any autonomic manifestations observed during her episodes.

Presentation of Symptoms

The patient’s clinical manifestations were multifaceted, intertwining physical symptoms with psychological distress. During the episodes, which could last from a few seconds to several minutes, her behavior and physiological responses diverged notably from those expected in typical epileptic seizures.

Primarily, the episodes were marked by pronounced involuntary jerking movements. These movements, while alarming, lacked the rhythmic and repetitive patterns usually associated with epileptic seizures. Instead, they appeared chaotic in nature, often culminating in periods of sustained postictal confusion, but without the postictal state typically observed in true seizure disorders.

An intriguing and significant symptom noted during these episodes was the pupillary dilation, which was particularly pronounced when the patient experienced heightened levels of stress or anxiety. This autonomic response is known to engage the sympathetic nervous system, indicating an acute stress reaction rather than a direct neurological trigger. The correlation between episodes and emotional distress was further exemplified by observations that episodes frequently arose following situations of emotional strain. For instance, stressful interactions with peers or academic pressures were often precursors to her episodes.

Additionally, the patient reported experiencing various psychosomatic symptoms outside of her episodic presentations. These included persistent anxiety, feelings of being overwhelmed, and physical manifestations such as palpitations and shortness of breath during moments of heightened emotional turmoil. Such symptoms were often misattributed to neurological causes in similar contexts but were clearly reflective of her underlying psychological state.

The presence of additional comorbidities, such as symptoms of depression and social withdrawal, compounded the complexity of her situation. Interviews with family members revealed a history of anxiety disorders within her family, suggesting a possible genetic predisposition to emotional disturbances. The interplay of these factors painted a comprehensive picture of a young individual grappling with significant mental strain, which directly influenced her physical responses.

The combination of these symptoms highlighted a complex interaction between psychological distress and physical manifestations, serving as critical indicators in her diagnostic journey. Recognizing this interplay was essential for the interdisciplinary team as they sought to establish a clearer understanding of her condition, paving the way for an effective management strategy targeted at both her mental and physical health challenges.

Treatment Outcomes

The management of the patient primarily focused on addressing the psychopathological underpinnings of her psychogenic non-epileptic seizures (PNES) while also providing strategies to mitigate the episodes themselves. A multidisciplinary approach was employed, involving neurologists, psychiatrists, and psychotherapy specialists, to address the multifaceted nature of her condition.

Upon diagnosis, an individualized treatment plan was established. This plan included cognitive behavioral therapy (CBT), which aimed to assist the patient in understanding and reframing her anxious thoughts and reactions linked to stress and emotional triggers. CBT has been shown to be effective in individuals with PNES by reducing the frequency of episodes through cognitive restructuring and learning coping strategies for anxiety-provoking situations.

The patient participated in weekly therapy sessions. During these sessions, she learned techniques such as relaxation training, mindfulness meditation, and grounding exercises that helped her manage anxiety and stress. These coping strategies played a crucial role in reducing the emotional intensity associated with her episodes. Over a period of several weeks, the patient reported a noticeable decrease in her overall anxiety levels, which correlated with a reduction in the frequency of her seizure-like episodes.

In addition to therapy, pharmacological intervention was considered to manage accompanying symptoms of anxiety and depression. A selective serotonin reuptake inhibitor (SSRI) was prescribed, aimed at stabilizing her mood and alleviating symptoms of emotional distress. The effectiveness of this medication was monitored closely, and adjustments were made based on the patient’s response. The combination of therapy and medication proved to be beneficial, as her self-reported anxiety levels decreased significantly over time.

During outpatient follow-ups, continuous assessments were carried out to track the patient’s progress. The frequency of her episodes diminished, and by six months post-treatment initiation, she had experienced only a few episodes, primarily during acute stress situations. This reduction in the frequency of episodes not only reflected improvements in her emotional state but also boosted her confidence and quality of life.

Moreover, the interdisciplinary team provided psychoeducation to the patient and her family, helping them understand the nature of PNES and the factors that contribute to its manifestation. By involving family members in the treatment process, the health care providers aimed to enhance the support network of the patient, which is often crucial for managing chronic psychological conditions. This family involvement also facilitated open communication about her symptoms and progress, contributing to a more supportive home environment.
