The data acquisition was obtained from different hospitals (departments of neurology and internal medicine) without common protocol that could impact the study results, especially in the low rate of stroke risk during

hospitalization. However, the work up of TIA follows the uniform recommendation of the German Society of Neurology and German Stroke Society. Another limitation was that the study protocol did not include the findings of the duplex sonography of the arteries in the neck and brain. Despite these limitations and risks (namely, radiation and iodine contrast exposure) that are associated with CCT (Brenner and Inhibitors,research,lifescience,medical Hall 2007), CCT is performed more frequently than MRI on a daily basis for various reasons. These reasons include the fast acquisition, economical factors, ability to reliably exclude a hemorrhage, availability, and

the ease of interpretation of CCT findings Inhibitors,research,lifescience,medical compared with other diagnostic brain imaging techniques. Conclusions The frequency of acute infarct that is detected by noncontrast enhancement Inhibitors,research,lifescience,medical CCT in patients with TIA is low and depends on the severity of the TIA symptoms and the assessment time. The use of the CCT tool to predict the stroke risk during hospitalization in patients with TIA is found to be inappropriate.

The incidence of combat-related posttraumatic Inhibitors,research,lifescience,medical Batimastat stress disorder (PTSD) continues to be a significant health concern for U.S. military soldiers currently serving under Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Surveys of military personnel returning from Afghanistan and Iraq suggest that anywhere between 8% and 17% of soldiers screen positive for PTSD symptoms (Hoge et al. 2004; Schneiderman et al. 2008; Smith et al. 2008). The most common symptom of PTSD is persistent neuro-psychological trauma (e.g., flashbacks, high arousal and anxiety, intrusive memories); however, increasing evidence suggests that PTSD also produces both acute and chronic neurocognitive deficits (Horner and Hamner 2002; Yehuda et al. 2006; Marx et al. 2009; Vasterling et al. 2009; Lagarde et al. 2010; but see Crowell et al. 2002; Burris et al. 2008).
