PART 2 Following on from the role of memory system in PTSD and simialr psychopathologies (and disorders with which PTSD is also co-occurring) “We propose a similar mechanism may underlie the development and persistence of some PTSD symptoms The traumatic memories of PTSD patients can be deficient […]
PART 1 This most excellent article (1) explains how two main memory systems relate to two manifestations related to PTSD, the enhancement and the impairment of traumatic memory which may be difficult to explain via a unitary model of memory, but these seemingly antagonistic effects can […]
This article (1) looks at how sufferers of PTSD have heightened activation of the emotional or fear based part of the brain, the amgydaloid part of the brain. We have suggested before in various blogs that this hyperactive amgydaloid region takes over from the more reasonable prefrontal cortex […]
In various blogs we have suggested that one of the main aspects of addictive behaviours is to act as the result of distress-based impulsivity or negative urgency. Here we explore in more details what we mean by that term negative urgency. Here we borrow from one article (1) […]
Alcohol dependence is thought of as a disorder with an overwhelming impulsive and compulsive “drive” towards alcohol consumption (Kamarajan et al. 2005), and an inability to “hit the brakes”, or inhibit alcohol consumption despite negative biological, psychological, legal, and social consequences (American Psychiatric Association 1994). Functional neuroimaging studies […]
In the first in a series of blogs we discuss the topic of why does the solution to one’s alcoholism and addiction require a spiritual recovery. This is a much asked question within academic research, although the health benefits of meditation are well known and life styles incorporating […]
A core aspect of alcohol dependence is poor regulation of behavior and emotion. Alcohol dependent individuals show an inability to manage the appropriate experience and expression of emotion (e.g., extremes in emotional responsiveness to social situations, negative affect, mood swings) (1,2). Dysfunctional emotion regulation has been considered a […]
Emotional dysregulation and altered reward sensitivity may underpin impulsive behavior and poor decision-making. Both of these tendencies can be seen in the “real-world” behavior of addicted individuals, but can also be studied using laboratory-based paradigms. Addiction is associated with a loss of control over drug use which continues in […]
Most alcoholics have difficulties with emotional and stress regulation.
As we have already suggested we feel that two main modifications need to be considered in relation to existing ‘conditioning’ theories of addiction : – 1. In neurobiological accounts of addiction there is no such thing as a positive or a negative reinforcement model of addiction or, in […]
