The question describes specific symptoms: anxiety, recurring nightmares, sleep disturbances, and concentration problems. Crucially, these symptoms occur more than 1 month after a major stressor.
These symptoms, occurring after a major stressor and persisting for more than a month, are characteristic diagnostic criteria for Post Traumatic Stress Disorder (PTSD). While other stress-related disorders share some symptoms, the timing (long after the event) and persistence strongly point towards PTSD.
Therefore, the cluster of symptoms described aligns precisely with the diagnostic profile of Post Traumatic Stress Disorder.
