Study Notes

Overview of Epilepsy

  • Epilepsy is characterized by recurrent seizures caused by abnormal brain electrical discharges.
  • Differentiates between recurrent seizures and isolated ones that can arise from various factors.

Diagnosis

  • Diagnosis relies on patient and witness accounts, medical history, and physical examination.
  • EEG confirms epilepsy type and origin but cannot exclude it.
  • Neuroimaging has limited specificity, as many patients show no distinct brain abnormalities.
  • Differential diagnosis is crucial, especially to distinguish from syncope, panic attacks, and other psychiatric conditions.

Functional Non-Epileptic Attacks (Pseudoseizures)

  • Pseudoseizures mimic epilepsy but lack true epileptiform activity.
  • They are often associated with psychosocial issues, psychiatric disorders, or past trauma.
  • Identifiable features suggest non-epileptic episodes, such as variability and lack of autonomic signs.
  • Evidence of awareness and complex behaviors during attacks can indicate pseudoseizures.

Psychiatric Aspects of Epilepsy

  • Increased psychiatric comorbidity occurs in 20-40% of epilepsy patients.
  • Various psychiatric disorders can manifest before, during, or after seizures.
  • Distinguishing between pre-ictal, ictal, and post-ictal psychiatric disturbances is essential.

Types of Seizures

  • Seizures are classified into focal and generalized categories.
  • Focal-onset seizures may become generalized; recognizing the onset type is crucial.
  • Avoid ambiguous terms like 'petit mal' and 'grand mal'.

Partial Seizures

  • Simple partial: No impaired consciousness, remains aware.
  • Complex partial: Involves altered awareness and may have psychiatric features.

Generalized Seizures

  • Includes various types:
    • Tonic-clonic: Characterized by tonic and clonic phases.
    • Absence: Brief loss of awareness without post-ictal symptoms.
    • Myoclonic and atonic seizures involve motor symptoms.

Temporal Lobe Epilepsy

  • Most common form; often presents with complex partial seizures.
  • Can include auras and various symptoms like déjà vu and vivid hallucinations.

Epidemiology

  • Affects approximately 7 in 1000 adults in the UK.
  • Experience of seizures peaks in early childhood and after age 65.
  • Chronic epilepsy affects only about 20% of individuals.

Aetiology

  • Age of onset helps in determining causes.
  • In newborns: Birth injuries, congenital issues, metabolic disorders.
  • In adults: Identifiable causes like cerebrovascular events, brain tumors, or head injuries.

Drug Therapy

  • Seizure thresholds can be influenced by various medications.
  • Careful monitoring is required when prescribing psychotropic drugs due to potential seizure exacerbation.

Depression and Emotional Disorders

  • Depression and anxiety are prevalent, affecting over 20% of epilepsy patients.
  • Risk factors for depression include family history and psychosocial factors like stigma.

Inter-Ictal Psychosis

  • Higher prevalence in individuals with epilepsy, particularly those with temporal lobe foci.
  • Characterized by religious and paranoid delusions; risk factors include focal lesions.

Suicide Risk

  • Higher occurrence rates of suicide and self-harm in epilepsy patients compared to the general population.
  • Associated with temporal lobe epilepsy and a history of surgical intervention.

Social Aspects of Epilepsy

  • Quality of life is impacted by seizure severity and psychiatric comorbidity.
  • Stigma and unpredictability of seizures contribute to social challenges.
  • Restrictions on driving can affect employment and independence.

Treatment Considerations

  • Treatment for psychiatric disorders should align with seizure management.
  • Interactions between antiepileptic and psychotropic medications must be carefully managed.
  • Close coordination between neurologists, psychiatrists, and primary care providers is essential for effective treatment.
