This document summarizes psychiatric manifestations that can occur with epilepsy. It discusses preictal, ictal, and postictal conditions as well as interictal personality disturbances, psychotic symptoms, mood disorders, violence, and suicide risk. Correct diagnosis can be difficult when psychiatric symptoms are severe without changes in consciousness. Maintaining suspicion for epilepsy even without classic signs is important. New psychiatric symptoms in a patient with epilepsy may represent disease evolution rather than an independent disorder.

2. Philosophy or science
 There is nothing either good or bad but
thinking makes it so
William
Shakespeare

3. Introduction
 Epilepsy is the most common chronic
neurological disease
 Its not a disease, should be considered as a
symptom of brain diseases

4. What is epilepsy
 Recurrent unprovoked seizure
 Caused by uncoordinated neuronal discharge

5. Is it simple to diagnose
 The diagnosis of epilepsy is often difficult
 Diagnosis is almost clinical
 A correct diagnosis can be particularly difficult
when the ictal and interictal symptoms of
epilepsy are severe manifestations of
psychiatric symptoms in the absence of
significant changes in consciousness and
cognitive abilities

6. Irony of epileptics
 A large fraction of patients with seizure
disorder are misdiagnosed and treated
inappropriately
 About one third of the epileptics are
misdiagnosed in both way
 Computerized diagnosis is trying

7. Why psychiatrists
 Psychiatric co morbidity is common in epilepsy
 Consideration of an epileptic diagnosis in
psychiatric patients
 The psychosocial ramifications of epilepsy
 The psychological and cognitive effects of
AEDs
 Shared pathophysiology
 Stigma & psychosocial impairment

8. Psychiatric aspect
 30 to 50 percent of epileptics have psychiatric
difficulties sometime during the course of their
illness
 The most common behavioral symptom of
epilepsy is a change in personality

9. Preictal conditions
 Autonomic sensations
 Increasing tension, anxiety, irritability, fear, panic
 Fullness in the stomach, blushing and changes in
respiration
 Cognitive sensations
 Dreamy states, forced thinking, dejà vu, jamais
vu
 Affective states
 Depression, elation
 Classical automatisms
 Lip smacking, rubbing, chewing

10. Ictal conditions
 Brief, disorganized, and uninhibited behavior characterizes
the ictal event
 The cognitive symptoms include amnesia for the time during
the seizure and a period of resolving delirium after the
seizure
 Transient confusional state, affective disturbances, anxiety,
automatism.
 On occasion abnormal mental state may be the only sign of
non-convulsive status epilepticus
 Psychosis-
 Sudden onset & termination of disturbances
 Olfactory & Gustatory hallucination
 Relative lack of first rank symptoms
 Amnesia for the period of disturbances

11. Post ictal conditions
 Diverse motor, sensory, cognitive & autonomic
symptoms may occur
 Post ictal violence may occur

12. Interictal
Personality Disturbances : patients with
epilepsy of temporal lobe origin
 Religiosity
 increased participation in overtly religious activities
 unusual concern for moral and ethical issues
 preoccupation with right and wrong
 heightened interest in global and philosophical
concerns.
 sometimes seem like the prodromal symptoms of
schizophrenia

13. Interictal- personality
disturbances
 Viscosity of personality
 Most noticeable in a patient's conversation
 Slow, serious, ponderous, overly replete with
nonessential details, and often circumstantial
 The listener may grow bored but be unable to find a
courteous and successful way to disengage from the
conversation
 The speech tendencies, often mirrored in the patient's
writing, result in a symptom known as hypergraphia,
which some clinicians consider virtually
pathognomonic for complex partial epilepsy.

14. Interictal- personality
disturbances
 Changes in sexual behavior
 Hypersexuality: deviations in sexual interest,
transvestism
 Hyposexuality: both by a lack of interest in sexual
matters and by reduced sexual arousal

15. Interictal- continue
Psychotic Symptoms
 Interictal psychotic states are more common
than ictal psychoses
 Schizophrenia-like interictal episodes can occur in
patients with temporal lobe epilepsy
 Risk factors
 female gender
 left-handedness
 the onset of seizures during puberty
 a left-sided lesion

16. Interictal- psychotic symptoms
 The onset of psychotic symptoms in epilepsy is
variable
 Classically, psychotic symptoms appear in
patients who have had epilepsy for a long time,
and the onset of psychotic symptoms is
preceded by the development of personality
changes related to the epileptic brain activity

17. Interictal- psychotic symptoms
 The most characteristic symptoms of the
psychoses are hallucinations and paranoid
delusions
 Patients usually remain warm and appropriate
in affect, in contrast to the abnormalities of
affect commonly seen in patients with
schizophrenia
 The thought disorder symptoms in patients with
psychotic epilepsy are most commonly those
involving conceptualization and
circumstantiality, rather than the classic

18. Interictal- continue
Violence
 Episodic violence has been a problem in some
patients with epilepsy, especially epilepsy of
temporal and frontal lobe origin.
 Whether the violence is a manifestation of the
seizure itself or is of interictal
psychopathological origin is uncertain

19. Interictal- continue
Mood Disorder Symptoms
 Mood disorder symptoms, such as depression
and mania, are seen less often in epilepsy than
are schizophrenia-like symptoms
 The mood disorder symptoms that do occur tend
to be episodic and appear most often when the
epileptic foci affect the temporal lobe of the
nondominant hemisphere
 The importance of mood disorder symptoms may
be attested to by the increased incidence of
attempted suicide in people with epilepsy

20. Risk factor of depression in
epilepsy
 Behavior
 FH of mood disorder
 Focus in temporal or frontal lobe
 Left side focus
 Psychosocial
 Perceived stigma
 Fear of seizure
 Pessimistic attribution style
 Decreased social support
 Unemployment
 Iatrogenic
 Epileptic surgery
 AED- polypharmacy with high serum levels

21. Interictal- continue
Suicide & deliberate self harm

22. Diagnosis
 A correct diagnosis of epilepsy can be difficult
when the ictal and interictal symptoms of
epilepsy are severe manifestations of
psychiatric symptoms in the absence of
significant changes in consciousness and
cognitive abilities
 Psychiatrists, must maintain a high level of
suspicion during the evaluation of a new
patient even in the absence of the classic signs
and symptoms

23. Previously diagnosed
 The appearance of new psychiatric symptoms
should be considered as possibly representing an
evolution in their epileptic symptoms
 The appearance of psychotic symptoms, mood
disorder symptoms, personality changes,
symptoms of anxiety should cause a clinician to
evaluate the control of the patient's epilepsy and to
assess the patient for the presence of an
independent mental disorder
 Compliance with the anticonvulsant drug regimen
and its adverse effects
 When psychiatric symptoms appear in a patient
who has had epilepsy in the past

24. Not previously diagnosed
Four characteristics should cause to be suspicious
:
 the abrupt onset of psychosis in a person
previously regarded as psychologically healthy
 the abrupt onset of delirium without a recognized
cause
 a history of similar episodes with abrupt onset
and spontaneous recovery
 a history of previous unexplained falling or
fainting spells

25. What makes us comfortable

Cyanotic skin changes during seizures Common None
Self-injury Common Rare
Incontinence Common Rare
Postictal confusion Present None
