Final answer:
PTSD is an anxiety disorder with effects like flashbacks, avoidance, hyperarousal, changes in feelings, and self-medication. It impacts relationships and can lead to additional mental and physical health issues.
Step-by-step explanation:
Post-traumatic stress disorder (PTSD) is an anxiety disorder that may occur after a person has experienced or witnessed a traumatic event. PTSD can cause a wide range of after effects which include but are not limited to flashbacks, avoiding situations that remind one of the trauma, hyperarousal, negative changes in beliefs and feelings, and severe anxiety. Some individuals with PTSD may also engage in self-medication, often with substances like alcohol, to cope with their symptoms.
Additionally, PTSD can have a profound effect on social relationships, employment, and overall well-being. Long-term effects may also include increased risk for other mental health disorders such as depression and anxiety, and physical health issues due to chronic stress. These after effects highlight the importance of early diagnosis and effective treatment for PTSD to mitigate these long-term consequences.
