Depression in Epilepsy: Drug and Non-Drug Interventions Based on Multimodal Pathogenesis

Area of Science:

• Neurology
• Psychiatry
• Neuroscience

Background:

• Depression frequently co-occurs with epilepsy, diminishing patient quality of life.
• The exact causes of depression in epilepsy are not fully understood.
• Existing research presents a fragmented view of the underlying pathophysiology.

Purpose of the Study:

• To review current research on the pathogenesis of depression in epilepsy.
• To explore the impact of pharmacological treatments on both depression and seizures.
• To discuss non-pharmacological interventions for managing comorbid depression.

Main Methods:

• Literature review focusing on monoamine neurotransmitters, neuroinflammation, Hypothalamic-Pituitary-Adrenal (HPA) axis, neurotrophic factors, mitochondrial dysfunction, and oxidative stress.
• Analysis of the dual effects of antidepressants and antiepileptic drugs (AEDs).
• Evaluation of non-drug interventions like Cognitive-Behavioral Therapy (CBT) and dietary changes.

Main Results:

• Multiple biological pathways contribute to depression in epilepsy.
• Some AEDs and antidepressants can worsen depression or seizures.
• Non-drug therapies show promise as adjunct treatments.

Conclusions:

• Optimizing treatment for epilepsy with comorbid depression necessitates personalized strategies.
• Careful selection of antidepressants and AEDs is crucial.
• Integrated approaches combining pharmacotherapy, CBT, and lifestyle modifications are recommended.
