The Impact of the Posttraumatic Personality on the Person’s Ability to Contract Marriage

The human brain is the central organ governing physical and psychical functions, defining individual identity and enabling free will. Canon law, grounded in the assumption of rational decision-making, must therefore address the implications of impaired brain function. This article explores how posttraumatic personality changes—stemming from craniocerebral injuries—affect brain function and potentially alter canonical legal status. The paper presents the genesis and classification of cranial traumas, including concussions, contusions, compressions, and collapses, as well as their physical and psychical consequences. Special attention is paid to posttraumatic disorders such as cerebrasthenia, epilepsy, dementia, and neuroses. The study also examines the legal and theological significance of psychical disorders resulting from brain trauma, particularly in relation to free will and moral responsibility. As such injuries become increasingly common in modern societies, a deeper understanding of their consequences is essential for aligning canonical norms with medical and psychological realities.
