Emotion recognition and social cognition in juvenile myoclonic epilepsy

Juvenile myoclonic epilepsy (JME) is the most common idiopathic generalized epilepsy. Disease onset is typically in puberty and poor social adjustment and behavioral disturbances, which resemble frontal lobe dysfunction, are often observed. In recent advanced brain imaging studies on JME patients, emotional and behavioral problems have been associated to subtle structural and functional alterations mainly in frontal cortex and thalamus. There is emerging evidence that patients with abnormal emotion processing and regulation, such as those with bipolar disorder, show disrupted connectivity between limbic structures and frontal cortices. There are no neuroimaging or neuropsychological studies related to emotion processing in patients with JME with afocus on limbic structures. We aimed to address the problem of emotional disturbances and social adjustment in JME patients from multiple aspects through thorough functional and structural assessment, which would potentially enable elaboration of aunifying concept explaining neurobiological background of disturbances in emotional processing and social adjustment in JME patients. Results of this study may potentially enable the development of psychological and pharmacological interventional strategies for managing behavioral disturbances in patients with JME.
