Quick answer
Hyperarousal (ICD-10: F43.1; ICD-11: 6B40) is a core feature of PTSD reflecting chronic sympathetic nervous system activation. TF-CBT and EMDR have the strongest evidence. Somatic and vagal approaches are valuable adjuncts. Suicidal ideation in PTSD context requires urgent clinical assessment.
