Optimism and pessimism as predictors of seizure group among patients with intractable seizure disorders.

The purpose of this study was to investigate the validity of the Revised Optimism-Pessimism Scale (PSM-R) as a measure of attributional style, and the incremental utility of optimism and pessimism as predictors of seizure group, in an intractable seizure disorder sample. Participants included adult patients with epileptic seizures (ES; n = 151) and psychogenic nonepileptic seizures (PNES; n = 173) whose diagnoses were confirmed by prolonged video/EEG monitoring (PVEM). Optimism and pessimism scores were computed from abbreviated versions of the MMPI for all participants.

Cortical correlates of self-generation in verbal paired associate learning.

Behavioral studies have shown that verbal information is better retained when it is self-generated rather than read (learned passively). We used fMRI and a paired associates task to examine brain networks underlying self-generated memory encoding. Subjects were 49 healthy English speakers ages 19-62 (30 female).

Future directions in the neuropsychology of epilepsy.

Two important themes for future clinical research in the neuropsychology of epilepsy are proposed: (1) the neurobiological abnormalities that underlie neuropsychological impairment in people with epilepsy, and (2) neuropsychological status of persons with new-onset epilepsy.

Moderating effect of optimism on emotional distress and seizure control in adults with temporal lobe epilepsy.

Stress is a commonly reported seizure precipitant among individuals with epilepsy. Yet, the relationship between stress and seizure susceptibility remains unclear. This study examined the relationship between emotional distress and lifetime seizure load in individuals with temporal lobe epilepsy (TLE), as well as the potential moderating effect of explanatory style on this relationship.

The effects of perceived emotional distress on language performance in intractable epilepsy.

We evaluated the potential moderating effect of emotional distress (Minnesota Multiphasic Personality Inventory 2, scales D and Pt) on language functioning (i.e., Boston Naming Test, phonemic paraphasic error production on the Boston Naming Test, Controlled Oral Word Association Task, Animal Naming, Token Test) in patients with left (N=43) and right (N=34) mesial temporal lobe epilepsy (MTLE) and frontal lobe epilepsy (FLE) (N=30).
