In the article by Dar LK regarding patients with conversion disorder, authors have brought awareness to the pervasiveness of childhood adversities and adult health risks in Pakistan. 1 The findings of this research were similar to Adverse Childhood Experience (ACEs) study which also demonstrated a positive correlation between the age of trauma and level of dissociation in adulthood. 2  There are certain limitations in the study by Dar LK. It is gender specific and has a small sample size; however, the authors validate the significance of childhood adversity and recommend a more thorough assessment of patients in order to develop the most appropriate treatment plan. In recent years, the subject of childhood adversity has gained serious attention of the Center of Disease Control and Prevention (CDC) and the World Health Organization (WHO). The significance of this issue is also reflected in published literature, ongoing researches and changes in clinical practice. 3  It is important to cite one of the largest studies done on childhood adversity. 2  CDC and Kaiser Permanente collaborated in the ACEs study, which demonstrated a correlation between ten adversities in childhood and adult health risks. This study was a retrospective and prospective study of over 17,000 patients completed in two waves of data collection. The childhood adversities included were: physical, sexual, and emotional abuse, domestic abuse, physical and emotional neglect,  household dysfunction, mental illness, substance abuseand divorce. 4  The study showed that the pervasive adversities occurring during growth and developmental phases disrupted the architecture of the brain resulting in lifelong neurodevelopmental consequences. These neurodevelopmental outcomes created social, emotional, and cognitive impairments which led to adult health issues and diseases, even in the absence of acquired health risks behaviors. ACE study showed a negative correlation between socioeconomic status and the number of adversities. Subsequently, high number of childhood adversities was associated with increased risks for psychological, behavioral, social, and poor health outcomes in adulthood. The WHO has adopted the Adverse Childhood Experience International Questionnaire, providing introductory materials, a guide for administration, and a questionnaire that can be utilized in all countries.2 However, this questionnaire requires validation in different health setups due to variations in psychosocial, cultural and other health care attributes. Additional retrospective and prospective longitudinal studies of victims of adversities are needed to determine if there is a neurobiological basis to functional neurological disorders, such as conversion disorder. This may be achieved by utilizing the ACEs questionnaire for local studies in Pakistan.
