Post-traumatic stress disorder (PTSD) is a disorder affecting the mental health of a person, who have stumbled across or observed any distressing event such as battle, sexual or physical abuse, a natural calamity, or a near-death occurrence of theirs/their loved one. The symptoms of PTSD include reoccurring recollections or flashbacks of the traumatic event, avoiding reminders of the incident, pessimistic feelings and emotions, and exaggerated response to stimuli. The symptoms of PTSD can vary in severity and may occur soon after the traumatic event or can develop months or even years later. The intensity and duration of the symptoms can also vary depending on the individual and the type of trauma experienced. PTSD can have a significant impact on an individual’s quality of life, relationships, and daily functioning. To diagnose PTSD, a mental health professional will assess an individual’s symptoms and their impact on their daily life. Treatment for PTSD can include therapy, medication, or a combination of both. Therapy can include cognitive-behavioural therapy (CBT), which aims to help individuals develop coping mechanisms and challenge negative thought patterns related to the trauma. Another therapy that has proven to be effective in treating PTSD is Eye Movement Desensitization and Reprocessing (EMDR). In addition, medications like antidepressants and anti-anxiety drugs can also be administered to alleviate the symptoms of PTSD. Additionally, lifestyle changes such as regular exercise, healthy eating, and stress management techniques like yoga or meditation can be helpful in managing symptoms of PTSD. It is important for individuals with PTSD to seek professional help as soon as possible. If left untreated, PTSD can worsen over time and have a significant impact on an individual's mental and physical health. PTSD is a treatable condition, and with the right support and treatment, individuals can manage their symptoms and lead fulfilling lives.
