Post-traumatic stress disorder (PTSD) is a mental health condition triggered by experiencing or witnessing a traumatic event, such as military combat, natural disasters, serious accidents, personal assaults or abuse. Individuals with PTSD often suffer from intense, disturbing thoughts and feelings related to their trauma, which can manifest as flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event. They may also experience emotional numbness, heightened arousal, and avoidance of situations or people that remind them of the trauma. These symptoms can disrupt daily life, making it challenging to function normally in personal, social, and professional settings.
