Acquired social disinhibition refers to a debilitating behavioural syndrome commonly reported after a severe traumatic brain injury (TBI) and is characterized by inappropriate social behaviour, often described as immaturity and insensitivity towards others. These behaviours can have enduring effects on the social capability of the individual and their relationships with others. However, research into socially disinhibited behaviour after TBI has been thwarted by a lack of consensus in the literature on definition and measurement. This review provides an overview of our current understanding of the definition, measurement, prevalence, associated outcomes, neuropathology, and underlying mechanisms of social disinhibition after TBI. In addition, suggestions are made for future research to further our understanding of this syndrome with the eventual aim of rehabilitating problematic behaviours. It is concluded that an improved understanding of what causes disinhibited behaviour after TBI will be necessary for the development of effective treatment strategies aimed at the rehabilitation of underlying impairments.

Symbioses occur in all higher organisms and have evolved to play an important role in host biology. Researchers have been studying the effects that microbial symbionts have on host biology for decades but have only recently begun to examine how they influence the brain and behaviour. This review aims to provide several examples of different symbionts that have demonstrated the ability to manipulate the behaviour of their hosts and described the current evidence for the molecular mechanisms used by the symbiont to alter the host’s nervous system and modify behaviour to illustrate the common points of interaction between symbiont and host.

A review of social disinhibition after traumatic brain injury

Impaired social cognition is a core deficit in frontotemporal dementia (FTD). It is most commonly associated with the behavioural-variant of FTD, with atrophy of the orbitofrontal and ventromedial prefrontal cortex. Social cognitive changes are also common in semantic dementia, with atrophy centred on the anterior temporal lobes. The impairment of social behaviour in FTD has typically been attributed to damage to the orbitofrontal cortex and/or temporal poles and/or the uncinate fasciculus that connects them. However, the relative contributions of each region are unresolved. In this Review, we present a unified neurocognitive model of controlled social behaviour that not only explains the observed impairment of social behaviours in FTD, but also assimilates both consistent and potentially contradictory findings from other patient groups, comparative neurology and normative cognitive neuroscience. We propose that impaired social behaviour results from damage to two cognitively- and anatomically-distinct components. The first component is social-semantic knowledge, a part of the general semantic-conceptual system supported by the anterior temporal lobes bilaterally. The second component is social control, supported by the orbitofrontal cortex, medial frontal cortex and ventrolateral frontal cortex, which interacts with social-semantic knowledge to guide and shape social behaviour.

A neuroanatomical and cognitive model of impaired social behaviour in frontotemporal dementia.

The purpose of the present study was to investigate two theoretical frameworks for understanding acquired deficits in social behavior in individuals with severe traumatic brain injury (TBI). Recent research has found that brain injury can lead to impairments in implicit processes including social cognition. Impairments in implicit social cognition have been recently advanced as an explanation for acquired social deficits, as implicit social cognition is hypothesized to mediate the processing and understanding of often subtle, nonverbal cues in social interactions. In contrast, the executive dysfunction account posits that deficits in higher order cognitive functions, such as attention, planning ability, and mental flexibility, are the locus for acquired deficits in social cognition and behavior. To test these two theories, 22 participants with severe TBI and 25 matched controls were administered a measure of implicit social cognition (Implicit Association Test, IAT), as well as two measure of explicit social attitudes and a range of executive functioning measures. The TBI participants were found to perform normally on the IAT and explicit measures of gender stereotyping but demonstrated executive deficits. Performance on the IAT and executive functions were correlated. Performance in general did not fit well with the implicit social cognition explanation for social dysdecorum following TBI. More evidence was found to support the executive account.
