Longitudinal changes in the dopamine transporter and cognition in suicide attempters with charcoal burning

Immediate and Delayed Neuropsychological Effects of Carbon Monoxide Poisoning: A Meta-analysis

“…Three studies investigated divided attention (Amitai et al, 1998;Rottman et al, 1995;Yang et al, 2015). As can be seen in Table 3, the pooled effect size for divided attention was 0.34 (95% CI [0.06, 0.62]; p = .019), indicating a small, yet significant, positive effect.…”

“…Three studies examined sustained attention in participants with CO poisoning and controls (Amitai, Zlotogorski, Golan-Katzav, Wexler, & Gross, 1998;Rottman, Kaser-Boyd, Cannis, & Alexander, 1995;Yang et al, 2015). Table 3 presents the pooled effect size of CO poisoning as compared to controls for sustained attention which was 0.62 (95% confidence interval [CI] [0.32, 0.92]; p < .001), with a medium, significant, positive effect, indicating that the controls performed significantly better than CO poisoning participants on tasks of sustained attention.…”

“…Four studies examined recent memory ability in participants with CO poisoning and controls (Amitai et al, 1998;Deschamps et al, 2003;Rottman et al, 1995;Yang et al, 2015). As seen in Table 3, the pooled effect size of CO poisoning participants and controls for recent memory was 0.23 (95% CI [− 0.56, 1.03]; p = .56), indicating a small, nonsignificant, positive effect.…”

“…Six studies examined sustained attention in participants with CO poisoning across time (i.e., between 6 weeks and 10 months post-exposure) (Chang et al, 2010;Hay, Denson, van Hoof, & Blumenfeld, 2002;Kesler et al, 2001;Porter, Hopkins, Weaver, Bigler, & Blatter, 2002;Weaver et al, 2002;Yang et al, 2015). As indicated in Table 4, the pooled effect size of participants with initial CO poisoning (Time 1) versus post-exposure (Time 2) performance on sustained attention was 0.54 (95% CI [0.34, 0.74]; p < .001), indicating a medium, significant, positive effect demonstrating that participants performed significantly better on tasks of sustained attention post-exposure as compared to initial CO poisoning.…”

Comparing the Relationship between Focus of Attention and Attention Bias in Suicide and Non-suicide Attempters

“…Therefore, emotion regulations like daily mood fluctuations and neurocognitive factors play important role in the clinical assessment of people with suicide preoccupation (Alonzo, Conway, & Modrek, 2016). People committing suicide with carbon monoxide poisoning have worse cognitive performance in domains of attention, memory, and executive function compared with people without the history of suicide (Yang et al, 2015). Indeed, cognitive factors like attention and it´s components like "focus of attention" and "attention bias" are also important in suicide behavior.…”
