“…Moreover, no correlation was found between these proteins and the anthropomorphic signals of adiposity observed in these patients (BMI or waist circumference) or these proteins and the length of illness. Serum BDNF was reduced in suicidal individuals soon after an attempted suicide (Dawood et al, 2007), in agreement with the changes in brain BDNF and its receptors observed in postmortem studies of depressive patients (Lee and Kim, 2011). Our sample included patients with suicide attempts during the last 15 days, time enough to "recover" possible decreases in the peripheral levels of BDNF associated with a suicidal attempt.…”

“…Like Dwivedi et al [6,7] , Karege et al [8] also concluded that BDNF may play a role in the pathophysiology of suicidal behaviour. Most recently, serum levels of BDNF were found to be significantly lower among depressed patients who had recently attempted suicide compared with non-suicidal depressed patients and healthy controls [9][10][11] . Low serum BDNF levels have also been found to be associated with vulnerability to traumatic life events in bipolar disorder [12] .…”

“…Para hacer frente a este problema, Dawood y cols. 28 , utilizaron el muestreo directo de sangre de la vena yugular interna y la arteria braquial, y este grupo determinó que el gradiente de concentración de BDNF veno-arterial actúa como un índice de producción de BDNF del cerebro. Basándose en esta determinación, se demostró que el gradiente de concentración de BDNF venoarterial se redujo significativamente en los pacientes con riesgo de suicidio medio-alto, en comparación con los de bajo riesgo.…”
