Psychosis Post-Traumatic Brain Injury: Causal Links and Nosographic Approaches about a Clinical Case

Psychotic manifestations, mainly consisting of delusions and hallucinations, are clinical entities that transcend nosographic boundaries and are present in various psychiatric and somatic disorders, particularly neurological and neurosurgical conditions. These psycho-behavioral manifestations can be isolated, coexist, or complicate a neurological deficit, thus raising questions about their imputability. Our goal is to shed light on the extent to which cranial traumas contribute to the development of psychiatric disorders and their specific characteristics. Ultimately, we aim to establish the foundations for an optimal biopsychosocial and legislative management approach if necessary. This will be illustrated through the clinical case of a patient who exhibited depressive symptoms shortly after the onset of delusional ideas with a psychotic nature, one year after experiencing a cranial trauma due to a public road accident. The somatic consequences of cranial trauma can cause psychotic symptoms. This is referred to as a post-traumatic psychotic disorder directly linked to localized brain damage, adhering to the structure-function paradigm. Such symptoms can appear up to four years later. The authors have reported that the onset of psychotic symptoms is frequently associated with depressive syndrome, which is a factor contributing to the chronicization of post-traumatic psychosis. Psychotic symptoms following Psychotic manifestations, such as delusions and hallucinations, can occur in various psychiatric and somatic disorders, especially neurological and neurosurgical conditions. These behaviors can occur alone, work in conjunction, or complicate a neurological deficit, raising questions about their connection to the condition. We want to understand how head injuries contribute to the development of psychiatric disorders and their specific characteristics. Ultimately, we aim to establish a comprehensive approach to managing these conditions, incorporating biological, ..
