PTSD is diagnosed based on specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders. To be diagnosed, typically a person must have experienced or witnessed a traumatic event and likely exhibits a combination of symptoms in four categories: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. These symptoms usually last for more than one month and cause significant distress or impairment in social, occupational, or other important areas of functioning. A mental health professional at Carencia conducts a thorough assessment to determine if these criteria are met.
