ibility but is different in nature. With PTSD, inattention is due to hypervigilance (for example, constantly scanning the environment for signs of threat). A person may also be distractable because of intrusive memories, traumatic memories, and internal reactions to trauma flashbacks/triggers....
Inhaled CO2 triggers panic attacks in a majority of individuals with PD, but only a minority of unaffected controls (Battaglia and Ogliari, 2005). In rodents, CO2 inhalation reduces amygdala pH, inducing acidosis and REVIEW fear behaviors (Coryell et al, 2007; Wemmie et al, 2003; Ziemann ...

Importantly, failure to replicate might also have occurred because EWA studies of depression have not con- trolled for exposure to extreme stressors, potent triggers of depression38,39 (although Dempster et al.34 reported the same number of stressful life events in cases and controls). EWAS of...
Any traumatic event can trigger PTSD, and it is important to know that PTSD is not a sign of weakness. Pellat outlined the following as the three main symptom groups of PTSD: (1) Intrusive symptoms/reexperience symptoms, (2) avoidance and blunting, and (3) hyper-arousal (excitement). ...
For non-trauma-focused interventions, unique therapy elements typically include strategies to increase patients’ understanding of the relationships between trauma-related triggers and substance use and to build coping skills to enable patients to break this reactive link (ICBT, McGovern et al., 2015...
All triggers land with the same intensity whether there is physical threat or emotional threat, and whether that threat is large, small, or just a reminder of a threat that happened in the past. The body and brain are not making these distinctions. It's good to remind myself that I'm...
The precise mechanisms that trigger inflammation during PTSD remain unclear. In this study, we provide new and interesting data which demonstrate a global defect consisting of decreased expression of AGO2 and DCR1, which in turn downregulates the expression of a large number of miRNAs in PTSD. ...
There is evidence that alcohol use may trigger genetic markers that create susceptibility to depression (Langbehn et al., 2006; Nurnberger et al., 2001), and that the depressant characteristics of alcohol may lead to depressed affects in anyone (Schuckit et al., 1997). It may also be that...
and subsequently experiences symptoms such as: Re-experiencing the trauma, for example, in flashbacks and nightmares; avoidance of places or activities that trigger memories of the traumatic event; arousal and reactivity associated with negative thoughts; aggressive behaviour that occurs with little or ...
