1. Introduction
Abdominal epilepsy is an intriguing neurological condition characterized by episodic abdominal pain, which may be accompanied by other epileptic or gastrointestinal symptoms. The condition was first systematically described by Maurice T. Moore in 1944 , who identified it as a unique form of epilepsy manifesting primarily with abdominal discomfort rather than conventional seizures. This initial recognition came at a time when the medical community was beginning to understand the diverse manifestations of epilepsy.
Despite its early description, abdominal epilepsy remains an under-recognized entity, obscured by its rarity and the generic nature of its symptoms. Such symptoms often mimic more common gastrointestinal disorders, leading to significant diagnostic delays and frequent misdiagnoses. The condition illustrates the broader challenges in epilepsy diagnosis, particularly for forms that present with atypical, non-seizure symptoms. Historically, the diagnosis of abdominal epilepsy has evolved from anecdotal case reports to a more defined clinical entity with specific diagnostic criteria. Early literature, including seminal works by Trousseau in the 19th century and later by Moore, highlights a pattern of misattribution to gastrointestinal etiology’s before recognizing the neurological roots.
Throughout the 20th century, as diagnostic techniques such as electroencephalography (EEG) became more sophisticated, the ability to identify and confirm cases of abdominal epilepsy improved. Nonetheless, the disorder continues to be a diagnostic challenge due to the nonspecific nature of abdominal pain and the need for EEG evidence of epileptiform activity coinciding with symptoms .
Modern advancements in neuroimaging and a deeper understanding of the brain-gut axis have further complicated the diagnostic landscape, suggesting that abdominal epilepsy may involve complex neurogastroenterological interactions. This contemporary view underscores the necessity for a multidisciplinary approach involving neurology, gastroenterology, and psychiatry to accurately diagnose and manage the condition.
Understanding the historical context, evolving diagnostic criteria, and recent treatment advancements is crucial for improving patient outcomes. This comprehensive perspective not only aids clinicians in recognizing abdominal epilepsy amid a plethora of potential diagnoses but also enriches our understanding of the diverse manifestations of epileptic disorders in general.
By delving into both the history and the contemporary challenges associated with abdominal epilepsy, we can better appreciate the nuances of this rare but impactful condition, fostering a more accurate and timely diagnosis, and ultimately, more effective management strategies.
2. Case Presentation
The subject of this report is a 23-year-old male with a protracted history of episodic, severe abdominal pain initiating at the age of eight. The pain episodes, characterized by their severity and abrupt onset, were frequently accompanied by vertigo and debilitating headaches, contributing to significant psychosocial challenges, including academic underachievement and the early onset of substance use disorders. Despite exhaustive and repeated gastrointestinal evaluations, which included a full spectrum of imaging and endoscopic procedures yielding no organic pathology, the patient's symptomatology persisted, confounding his clinical management.
The patient was subsequently referred for psychiatric evaluation, given the presence of concurrent depressive symptoms and the absence of an organic diagnosis, raising the suspicion of a psychogenic pain disorder. Initial psychiatric management, oriented towards treating an assumed psychosomatic illness, proved ineffective, leading to further scrutiny of his clinical history and symptomatology.
A meticulous re-evaluation of the patient’s symptom chronology and characteristics revealed a distinct pattern suggestive of neurological involvement episodes of pain were stereotyped in nature, with a clear temporal pattern and associated autonomic manifestations, such as pallor and sweating. This pattern, alongside the neuropsychiatric comorbidities, propelled the decision to conduct an electroencephalography (EEG), which demonstrated left fronto-temporal paroxysmal activity, a finding not uncommon in focal epileptic disorders but rare in the context of abdominal pain (figure 1).

The diagnosis of abdominal epilepsy was thus established, redirecting the therapeutic approach towards the administration of Carbamazepine. The patient's response to Carbamazepine was marked by a substantial alleviation of abdominal symptoms and a concomitant stabilization of mood and decrease in substance use, affirming the diagnosis and underscoring the neurological underpinnings of his presenting complaints. This case exemplifies the critical need for a high index of suspicion and an interdisciplinary approach in the diagnosis of abdominal epilepsy, a rare but impactful mimicker of gastrointestinal and psychogenic disorders in psychiatric practice.
This comprehensive evaluation and management highlight the complex interplay between gastrointestinal, neurological, and psychiatric symptoms in abdominal epilepsy and advocate for greater awareness and consideration of this diagnosis in similar clinical presentations to prevent years of patient distress and mismanagement.
3. Discussion
Abdominal epilepsy, often a diagnosis of exclusion, presents significant clinical challenges due to the episodic and nonspecific nature of its symptoms. This condition has a rich history of evolving understanding, initially observed in the early 20th century but deeply rooted in the 19th-century medical discussions of atypical epilepsy forms.
The differential diagnosis for abdominal epilepsy includes common conditions such as irritable bowel syndrome (IBS), gastrointestinal infections, abdominal migraines, and psychogenic disorders such as anxiety and somatoform disorders. These are frequently considered before neurological causes due to their prevalence and overlapping symptomatology .
3.1. Historical Context
The concept of epilepsy manifesting primarily with abdominal symptoms was sporadically reported as early as the 1920s but gained more significant attention after Maurice T. Moore's seminal work in 1944. Moore's description established a clearer link between abdominal pain and epileptic discharges, providing a foundation for subsequent investigations .
3.2. Recent Advances and Literature
Our case is the first documented and published case in Morocco; other cases of abdominal epilepsy are described in North Africa including Tunisia , Algeria and Egypt .
Abdominal Epilepsy (AE) is a rare disorder that, due to the vague nature of its symptoms, is often misdiagnosed or missed entirely. It commonly occurs in children, though there are documented cases in adults as well . AE is characterized by unexplained, paroxysmal gastrointestinal complaints and autonomic symptoms such as pallor, cold sweating, dry mouth, and constipation. Abdominal auras may also be present, accompanied by manual and oral automatisms, which constitute an automotor seizure . The frequency of vomiting typically ranges from three attacks in one hour to ten days over the last six months, with patients vomiting up to four times in one hour during each attack. Central nervous system symptoms include confusion, fatigue, headache, dizziness, syncope, and lethargy. Disorientation during episodes, followed by fatigue and a tendency to sleep, are crucial symptoms for establishing the diagnosis . case of a child with abdominal epilepsy who had suffered from recurrent episodic abdominal pain and cyclic vomiting for 3 years misdiagnosed as ‘acid peptic disease .
In our case, the manifestations included severe episodes of abdominal pain, marked by their intensity and sudden onset, frequently accompanied by vertigo and debilitating headaches. However, we did not find any similar cases in the literature that were revealed through psychiatric symptoms.
Recent studies emphasize the critical role of electroencephalography (EEG) in diagnosing abdominal epilepsy. Lo Bianco et al. and Harshe et al. discuss the often-overlooked epileptiform activities during routine clinical assessments that are crucial for a definitive diagnosis. Furthermore, Jagtap et al. highlight EEG's utility in differentiating this condition from other gastrointestinal or psychogenic causes .
Treatment paradigms have shifted towards more targeted pharmacological interventions. Carbamazepine has been a cornerstone of therapy, demonstrating efficacy in symptom management and normalization of EEG findings. Recent reviews, advocate for the use of newer antiepileptic drugs (AEDs) with more favorable side effect profiles, enhancing patient outcomes in atypical epilepsy syndromes .
3.3. The Need for a Multidisciplinary Approach
Given the complexity of symptoms that mimic several other disorders, a multidisciplinary approach is vital for accurate diagnosis and effective management. This approach involves neurologists, gastroenterologists, and psychiatrists to navigate the challenging diagnostic landscape and tailor treatment strategies to individual patient needs.
4. Conclusion
Abdominal epilepsy exemplifies the intricate interplay between various bodily systems and the importance of a comprehensive evaluation. The disorder, while rare, underscores the necessity of considering neurological causes in patients with chronic, unexplained abdominal pain. This case and discussion highlight the evolving understanding and strategic management needed to address such complex medical conditions effectively.
