Dissociating the impact of alexithymia and impaired self-awareness on emotional distress and aggression after traumatic brain injury.

Objective: Alexithymia, a deficit in identifying and describing feelings, is prevalent in traumatic brain injury (TBI). Sometimes referred to as "emotional unawareness," we sought to investigate whether alexithymia after TBI was related to, or distinct from, impaired self-awareness (ISA) and whether the two predicted differentiable emotional and aggression profiles. Further, the mediating role of frontal system behaviors (disinhibition, dysexecutive function, apathy) was explored.

Observations on Working Psychoanalytically with a Profoundly Amnesic Patient.

Individuals with profound amnesia are markedly impaired in explicitly recalling new events, but appear to preserve the capacity to use information from other sources. Amongst these preserved capacities is the ability to form new memories of an nature - a skill at the heart of developing and sustaining interpersonal relationships. The psychoanalytic study of individuals with profound amnesia might contribute to the understanding the importance of each memory system, including effects on key analytic processes such as transference and countertransference.

Impaired auditory selective attention ameliorated by cognitive training with graded exposure to noise in patients with traumatic brain injury.

Patients who suffer traumatic brain injury frequently report difficulty concentrating on tasks and completing routine activities in noisy and distracting environments. Such impairments can have long-term negative psychosocial consequences. A cognitive control function that may underlie this impairment is the capacity to select a goal-relevant signal for further processing while safeguarding it from irrelevant noise.
