This article focuses on a detailed case study of a 36-year-old female with a dual diagnosis combining intellectual disability and post-traumatic stress disorder (PTSD). The interest of this case is to show the complexity of differential diagnosis and biopsychosocial therapeutic management in this type of patient.

The patient underwent a thorough psychiatric evaluation using psychometric scales, leading to the diagnosis of PTSD with psychotic symptoms comorbid with generalized anxiety and depression, against a background of moderate to severe intellectual disability. Multimodal treatment combining pharmacotherapy, cognitive-behavioral therapies (CBT and EMDR) and psychosocial intervention was instituted over several months, leading to a marked improvement in symptoms as assessed by follow-up psychometric evaluations. This case illustrates the need for a high level of diagnostic suspicion and specialized interdisciplinary care for this population vulnerable to trauma and mental disorders.
