This chapter uses a case-based approach to describe electrographic patterns associated with coma. These are rare and, though non-specific, may suggest particular underlying etiologies. The electrographic pattern of extreme delta brush (EDB) may be seen with anti-NMDA receptor encephalitis. Alpha-coma is a pattern of continuous unreactive alpha or alpha-theta range activity that may be seen in coma after cardiac arrest or in those with pontine injury. It may resemble normal wakefulness. Spindle-coma and beta-coma are also described. Electrocerebral inactivity (ECI) is the absence of all non-artifactual electrical activity on an EEG, when recording using minimal specified technical standards in patients with cerebral death (brain death).

The chapter summarizes the conceptual foundations of, and research on, emotional creativity (EC). Emotional creativity is defined as a pattern of cognitive abilities and personality traits related to originality and appropriateness in emotional experience. Emotional creativity is related to personality traits (e.g., openness to experience), positive affect, post-traumatic growth, and engagement in creative leisure activities. In applied settings, emotional creativity is related to innovative performance of employees as well as higher teaching efficacy. Meta-analysis revealed that women showed higher emotional creativity than men. Emotional creativity is also lower in older adulthood compared to younger age. Because the levels of EC are sensitive to the decline of cognitive functions in older adults, their decrease can be considered as one of the indicators of cognitive aging. Recent research in clinical neuropsychology has also revealed that older adults in the early stages of Parkinson’s disease showed decreased emotional creativity compared to healthy older adults. Several directions and research questions for future research are developed.
