  • No financial support from pharmaceutical companies. Information obtained from best available evidence from: Medical Literature Clinical Experience Disclosures
  • Slide 3
  • Epilepsy The management of patients with epilepsy is focused on: Controlling seizures Avoiding treatment side effects Maintaining quality of life.
  • Slide 4
  • Epilepsy and Quality of Life If seizure free, people with epilepsy enjoy a quality of life similar to the general population. One third of people with epilepsy continue to have seizures despite treatment. Because people with recurring seizures may have lower quality of life, every effort must be made to restore quality of life.
  • Slide 5
  • Possible Consequences of Epilepsy May be unable to legally drive. May have memory problems or cognitive issues. May be exposed to stigma or feel embarrassment. May have restricted independence. Medication dependence. Employment problems. These quality of life issues are important!
  • Slide 6
  • Adjustment Disorder When coping and problem-solving strategies fail, depressed mood and anxiety symptoms may result. This isnt necessarily a disorder, but rather acknowledgement that the person is having trouble adjusting to a life change or a new stressor. Bolstering social support, attending support groups, and learning new coping skills often helps adjustment and leads to resolution of symptoms.
  • Slide 7
  • Feeling sad sometimes is normal Feeling sad, blue, or down is part of our normal human experience. Appropriate when we experience tragedy, loss, or receive bad news. When these feelings persist for more than 2 weeks and also interfere with daily functioning, then we think about Major Depression.

  • Epilepsy and Depression Depressed mood is NOT normal in people with epilepsy. Depression can be part of a complex partial seizure. Depression can also be pre-ictal or post-ictal. Untreated depression is associated with more difficulty achieving seizure freedom.
  • Slide 9
  • Depression Depression is under-recognized; occurs in up to 43% of people with epilepsy. Depression is a significant factor adversely affecting quality of life. Risk factors for depression: Epilepsy-related disability Unemployment Activity restriction/Loss of Independence Impaired social support Stigma associated with Epilepsy
  • Slide 10
  • What causes Depression in Epilepsy? Psychological factors: difficulty coping with stressors, such as recurrent seizures real or perceived losses life experiences that set the stage for later depression Biological factors: prior history of mental illness family history of mental illness some seizure types Epilepsy itself increases the risk of depression Social factors: social isolation financial issues limits on independence
