Study Notes

Classification of Psychiatric Symptoms and Syndromes in Epilepsy

  • Fenton (1981) developed a system for classifying psychiatric disorders in epilepsy, finding widespread use (Table 6.9)
  • Psychiatric presentations in epilepsy may be attributed to the underlying cause of seizures.
  • If not a clear relationship, there might be a temporal relationship between episodic psychiatric symptoms and seizures.
  • Certain psychiatric presentations may precede or arise as a direct manifestation of an epileptic discharge.
  • Some patients develop persistent or recurrent psychiatric disorders unrelated to seizure activity.
  • Most peri-ictal presentations are unique to epilepsy (e.g., prodromal symptoms, epileptic auras, and post-ictal psychosis).
  • Interictal disorders include standard psychiatric conditions like depression or schizophrenia.
  • The term "organic" might be used to recognise a presumed causal association with epilepsy (e.g., organic depressive disorder, organic psychosis).
