Background  Cingulate gyrus epilepsy is controversial because it may overlap with other frontal lobe epilepsy syndromes. Reported cases are rare in the pre–magnetic resonance imaging literature but are more common thereafter. Information about peri-ictal and ictal behaviors is scarce.

Objectives  To characterize epilepsy originating from the cingulate gyrus and to report surgical outcomes.

Design  Case studies.

Setting  Academic research.

Patients  We report 3 surgically treated cases of cingulate gyrus epilepsy, with seizure-free or almost seizure-free outcomes. The cases were identified from a database of 4201 consecutive epilepsy monitoring unit admissions since October 1998 through September 2008. All 3 cases involved cingulate lesions.

Main Outcome Measures  Neuroimaging, video electroencephalographic, pathologic, and surgical outcome data were reviewed.

Results  All 3 patients had lesional left anterocingulate seizures confirmed by magnetic resonance imaging and experienced cessation of seizures after lesionectomy. Two patients had auras (fear and laughter) previously associated with cingulate gyrus epilepsy. All patients had clinical features consistent with frontal lobe epilepsy, including hyperkinetic behavior and ictal vocalization. Two patients had behavioral changes with aggression, personality disorder, and poor judgment; some behavioral episodes lasted for days and were socially devastating. One patient, a commercial pilot, showed behavior as a passenger that resulted in a diversionary landing. The other patient demonstrated behavior that led to his arrest, and he was almost arrested again in the hospital for threatening security officers. Aberrant behaviors in all 3 patients completely resolved after lesionectomy.

Conclusions  Lesional cingulate gyrus epilepsy is uncommon. Our 3 confirmed cases included 2 patients with unique and severe behavioral changes that resolved with lesionectomy.

Cingulate gyrus epilepsy is controversial because it may have distinct clinical features or it may overlap with other frontal lobe epilepsy syndromes. The term anterior cingulate epilepsy was first used in 1957 by Andy and Chinn1 to describe an experimental epilepsy model in cats. In 1970, Mazars2 published “Criteria for Identifying Cingulate Epilepsies” and reported 36 cases. This study predated magnetic resonance (MR) imaging and computed tomography (CT), and localization by intracerebral depth electrodes was problematic by today's standards. In 1989, the International League Against Epilepsy3 included cingulate epilepsy as a type of frontal lobe epilepsy in the proposed classification of epilepsy and epileptic syndromes. The commission first described general features that strongly suggest an epilepsy diagnosis of frontal origin (short seizures, minimal or no postictal confusion, rapid progression to secondary generalized seizures, prominent motor manifestations, complex gestural automatisms, and frequent falling when the discharge is bilateral), and then briefly described seizure subtypes. Cingulate gyrus epilepsies were described as consisting of complex partial seizures with complex motor gestural automatisms at onset, autonomic signs, and changes in mood and affect. Approximately 3 years later, Chauvel et al4 published a review of patients with anterocingulate epilepsy. They attempted to describe a syndrome based on 66 seizures in 16 patients, who were not discussed or described individually; it was unclear how the epileptic focus was identified. They described intense manifestations exceeding those produced by electrical stimulation, with intense fright, facial expression of fear, and incomplete loss of consciousness. In 2000, Williamson et al5 debated the existence of such an entity, claiming that it is hard to distinguish clinically between anterocingulate epilepsy and other frontal lobe syndromes.

We report 3 surgically treated cases of lesional cingulate gyrus epilepsy, with early seizure-free outcomes. Cases were identified from a database of 4201 consecutive epilepsy monitoring unit admissions from October 1998 through September 2008, at Parkland Memorial Hospital and the University of Texas Southwestern Epilepsy Center. Cases with a mesial frontal focus were then limited to 3 patients having seizures originating from the cingulate gyrus. The epileptogenic zone was confirmed by MR imaging (Figure), video electroencephalogram (EEG), intraoperative electrocorticography, single-photon emission CT images, neuropsychological evaluation, and good postsurgical reduction in seizure frequency. We reviewed the history, clinical manifestations, radiological findings, neurophysiological data, and surgical outcomes. Written consent to approve research on cases is routinely obtained from all patients before proceeding with EEG monitoring.

The EEG for case 2 (Table 1) was recorded using a commercially available system (BMSI; Nicolet, Milwaukee, Wisconsin). The EEGs for the other 2 cases were recorded using a digital video system (Stellate; Natus Medical Incorporated, San Carlos, California) with a 250-Hz sampling rate and the 10-10 modified combinatorial nomenclature system of electrode placement with the addition of ECG, FT9-10, TP9-10, AF7-8, FPz, Oz, Cz, and Fz. Ictal recordings and behavioral events were identified by the patient, family, or epilepsy monitoring unit staff or by computer. Informative ictal and interictal digital EEG samples were analyzed by montage reformatting using referential, bipolar, mean reference, and Laplacian montages with digital high-pass and low-pass filtering or 60-Hz notch filtering as needed for optimal waveform display.

Table 1 gives details of the cases. The behavioral changes associated with seizures in case 1 and in case 2 were unusual and profound. Case 1 demonstrated aggression and paranoia; the patient's postictal behavioral changes were long lasting. Behavioral problems in the setting of a normal interictal EEG had previously led to the diagnosis of nonepileptic spells and a personality disorder. He used to trade in electronics and lost his job as a consequence of the seizures. At one point, his postictal aggression led to imprisonment. In case 2, motor aggression, poor judgment, and paranoia were noted, mainly postictally. These signs were more profound after prolonged clusters of seizures. The patient previously worked as a commercial pilot and as a passenger had a series of seizures that resulted in the flight's being diverted for a medical emergency landing; during the flight, he was uncontrollably wandering up and down the aisle of the plane, often running up against the bulkhead. He was placed on medical leave but was able to return to work as a flight instructor after epilepsy surgery controlled his seizures.

Two patients (one with an aura of intense fear and the other with an aura of laughter without mirth) had simple partial seizure symptoms that were previously linked to the cingulate gyrus. The third patient described a “freezing” aura. To our knowledge, this is the first time an aura of freezing has been reported in association with cingulate gyrus epilepsy.

All 3 patients had complex ictal motor behavior, suggesting a frontal origin of these seizures before radiological or electrophysiological methods of diagnosis.

Ictal EEGs in 2 patients were obscured by muscle artifacts, while 1 patient had an EEG with left frontocentral slowing only and no specific spikes or sharp waves during the event.

Lesionectomy was performed in all of our patients. The surgical procedures produced good outcomes in terms of seizure control and resolution of behavioral problems. Case 1 was almost seizure free at 9 months after surgery, with only 2 seizures during this period (the frequency before surgery was 6-10 per day). A better outcome was achieved in case 2, who as of this writing has been seizure free for 11 years and not receiving antiepileptic drugs for the past 7 years. Case 3 was seizure free for 8 months before recurrence, but with better control and more than 98% reduction in seizure frequency. We believe that the only reason she is not seizure free is the recurrence of her glioma after surgical resection.

The cingulate gyri are situated in the medial pericallosal aspect of each frontal lobe. Because of diffusely projecting connectivity, the cingulate gyrus is an important structure in seizure propagation. It is composed of the anterocingulate cortex and the posterocingulate cortex. The anterocingulate gyrus is part of the Papez circuit and has the following 3 functional subdivisions: (1) The premotor division has projections to the spinal cord, red nucleus, and motor cortex. It receives projections from different thalamic nuclei. (2) The affect division has extensive connections with amygdala, periaqueduct gray matter, and autonomic brainstem nuclei and helps in controlling emotional autonomic responses. Electrical stimulation of this division may result in fear, pleasure, and agitation. (3) The cognitive division is found in the caudal areas and helps in avoidance learning memory. The posterocingulate cortex represents a separate entity that has different connections, histologic features, and function. It has a role in visuospatial and memory functions.68

Although some authors discussed the futility of trying to distinguish cingulate gyrus epilepsy from other frontal lobe epilepsy syndromes based on semiological results alone,5 we believe that lesional cingulate gyrus epilepsy can be considered a specific frontal lobe epilepsy syndrome or a distinctive constellation of findings. However, we acknowledge that in nonlesional cases it is hard to make such a differentiation without intracranial ictal recordings, leading to limited corticectomy and excellent seizure outcome.

Diagnosis of neocortical epilepsies was facilitated after the introduction of MR imaging and other neuroimaging modalities. As of 2009, 14 cases of confirmed cingulate gyrus epilepsy were reported.820 Our study results are consistent with previous findings about cingulate gyrus epilepsy (Table 2). Not surprising, all of our patients had complex motor activity during their seizures, similar to what has been previously reported. Twelve of 14 reviewed cases had complex motor activity; the 3 most commonly reported activities are thrashing and kicking, grasping, and running. There is a long list of other reported activities, including crying, spitting, grasping, hair fixing, lip smacking, head touching, mouth puckering, hand shaking or clapping, and repeated kissing or sucking.819 Some cases demonstrated myoclonus without other marked or noticeable motor activity.17

Behavioral problems and personality changes are associated with cingulate gyrus epilepsies.4,8,21 However, we report herein striking behavioral alterations that manifested mainly as motor and verbal aggression, as well as paranoid delusions. Personality and behavioral changes may persist interictally and may resolve after lesionectomy. We believe that these behavioral phenomena in our patients were postictal and interictal manifestations of seizures. This conclusion is supported by several lines of evidence. The severity of our patients' behavioral problems correlated with the frequency and severity of seizures. Behavioral alterations almost completely resolved after surgery. Previously described patients demonstrated personality changes characterized as autistic, reclusive, sociopathic, self-mutilating, and obsessive-compulsive.816 Most of these changes were reversed after surgery. Major behavioral alterations were reported in 5 cases among 14 reviewed herein, which we believe to be an underreporting.8,10,14,16 The changes were postictal or interictal or were categorized as personality disorders. In our series, one patient (case 2) demonstrated laughter without mirth, which was reported in 5 cases8,11,13,15,18 among 14 reviewed. Our search for published cases with gelastic seizures revealed 12 gelastic epilepsy cases originating from the frontal lobe without a hypothalamic lesion and 5 cases originating from the cingulate gyrus.22 Thirty-four gelastic cases of temporal origin were reported before 1997; some were associated with a sense of mirth.22 Similar to our results, poorly localizing interictal and ictal EEG findings are commonly reported in seizures originating from the cingulate gyrus. Ictal EEG suggested the correct lateralization in 7 cases among 14 reviewed9,1113,1618 and a frontal origin in 6 cases,8,11,12,16,18,19 while it suggested both the correct lateralization and a frontal origin in only 3 cases.12,16,18

We report herein prolonged periods of aggression (case 1 and case 2), paranoia (case 1), and an aura of freezing (case 3) in cingulate gyrus epilepsy. Lesional cingulate gyrus epilepsy can be diagnosed by MR imaging of the brain, nonspecific interictal EEG, poorly localizing or nonspecific ictal EEG with or without behavioral or personality disorder, and seizures with unusual motor manifestations. Recognizing such a pattern will assist in correct early diagnosis and help avoid misdiagnosis of nonepileptic seizures. Recognition of nonlesional cases would be more difficult without intracranial recordings.

In summary, cingulate gyrus epilepsy is a rare entity. It should be suspected in patients who are seen with a frontal lobe epilepsy syndrome (short lasting, frequent, and complex stereotyped prominent motor seizures with or without vocalization and a minimal postictal phase) and with 1 or more of the following: (1) laughter without mirth, especially at the beginning of the seizure; (2) a sense of fear with or without facial expression, especially at the beginning of the seizure; or (3) striking and profound behavioral or personality changes that may last for weeks. Neuroimaging is useful in lesional cases, whereas scalp EEG is usually not helpful. Our experience shows that lesional patients have good outcomes after surgical resection, which is somewhat dependent on the nature of the lesion (eg, neoplasm vs stable lesion).
