Post-Traumatic Stress Disorder (PTSD) exerts a profound impact on the mental health and well-being of new immigrants and refugees. These individuals have often experienced traumatic events in their home countries, such as war, violence, persecution, or displacement, which can leave lasting psychological scars. PTSD manifests through a range of symptoms, including intrusive memories, nightmares, hyperarousal, avoidance behaviours, and emotional numbing. For immigrants and refugees, navigating a new culture, language, and social environment while simultaneously dealing with the aftermath of trauma can intensify the challenges they face. PTSD can undermine their ability to integrate into their new communities, form relationships, secure employment, and adjust to their new lives. Additionally, cultural differences in understanding and addressing mental health issues can further complicate access to appropriate support and treatment. Recognizing the significant impact of PTSD on new immigrants and refugees is crucial in designing inclusive and culturally sensitive interventions to address their mental health needs and facilitate their healing and successful integration into their new societies.
