This study identifies "epileptosis," a syndrome linking epilepsy and psychosis, characterized by shared affective and EEG anomalies. The mechanism involves limbic system lesions and pathological learning, often misdiagnosed as hysteria.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Epileptology

Background:

  • Patients with epilepsy and psychosis exhibit shared affective disorders and EEG anomalies.
  • These episodes are triggered by biological or psychosocial stimuli and can mutually provoke each other.
  • The syndrome, termed 'epileptosis,' suggests a link between limbic system dysfunction and affective disturbances.

Purpose of the Study:

  • To investigate the shared clinical and laboratory parameters in patients with epilepsy, psychosis, and comorbid symptoms.
  • To propose a unifying mechanism for the co-occurrence of epileptic and psychotic phenomena.
  • To differentiate epileptosis from conditions like hysteria and malingering.

Main Methods:

  • Clinical monitoring of 102 patients across three groups: epileptics, psychotics, and those with both conditions.

  • Analysis of clinical and laboratory parameters, including electroencephalography (EEG) and stereo-EEG.
  • Correlation of affective disorders with epileptic activity, particularly within the amygdalo-hippocampal complex (AHC).

    • Main Results:

    • All patient groups shared sudden states of dysphoria, panic anxiety, and horror, with correlated EEG anomalies.
    • Triggers included biological factors (hypoglycemia, alcohol) and psychosocial stressors.
    • Epileptic focus in the AHC was linked to affective states and psychotic hallucinations, influenced by pathological learning.

    Conclusions:

    • Epileptosis is proposed as a syndrome resulting from limbic and brainstem modulation system lesions.
    • The amygdalo-hippocampal complex plays a crucial role in triggering both epileptic and affective/psychotic episodes.
    • Misdiagnosis is common due to variable presentation and normal scalp EEG findings.
