PTSD Case Study: Post-Traumatic Stress Disorder, Treatment and Recovery
PTSD Case Study: Patient Background
This PTSD case study follows Meera (name changed), a composite example that reflects how post-traumatic stress disorder commonly develops after a frightening event and how it is assessed and treated at Calida Rehab. The details are illustrative and do not describe any one identifiable person.
Meera is a 31-year-old school teacher from Navi Mumbai. She lives with her husband and her parents-in-law. Eight months before she came to Calida Rehab, the shared cab she was travelling in was hit from behind by a speeding truck on the expressway. She was trapped in the vehicle for about forty minutes until help arrived, and a co-passenger sitting next to her was critically injured. Meera had a fractured arm and recovered physically in about three months. Her family expected her to settle down once the injuries healed. Instead she began sleeping badly, stopped travelling by road and took leave from school for four months. She became jumpy and short-tempered, and had started drinking in the evenings to fall asleep.
Before the case itself, a short note. Post-traumatic stress disorder (PTSD) is a mental health condition that can follow an event involving actual or threatened death, serious injury or sexual violence. A person may live through the event, witness it, or learn that it happened to someone close. Most people who go through trauma do not develop PTSD, and many recover on their own with time and support. In some people the fear response does not settle, and the memory keeps coming back as if it were happening now. For the full picture, read our pages on post-traumatic stress disorder and PTSD treatment.
Symptoms: How PTSD Showed Up
PTSD symptoms fall into four groups. A person does not need every symptom, but the symptoms must last for more than a month and cause real distress or difficulty in daily life. The signs below are common.
Intrusive symptoms (the memory keeps returning)
- Unwanted, distressing memories of the event
- Nightmares about the event or related themes
- Flashbacks, where the person feels or acts as if it is happening again
- Strong distress or a racing heart when reminded of the event
Avoidance
- Avoiding thoughts, feelings or conversations about the event
- Avoiding places, people, vehicles or situations that are reminders
Negative changes in thinking and mood
- Persistent fear, guilt, shame or anger
- Blaming oneself or others in an unrealistic way
- Feeling detached from people, or emotionally numb
- Loss of interest in activities once enjoyed
- Difficulty remembering important parts of the event
- Strongly negative beliefs, such as feeling unsafe everywhere
Arousal and reactivity
- Being constantly on guard or easily startled
- Irritability, anger outbursts or reckless behaviour
- Trouble sleeping
- Trouble concentrating
In this case: Meera had nightmares of the truck and the sound of the impact almost every night, and woke up sweating several times a week. Loud horns or a car braking behind her made her heart race and her hands shake. She would not travel on the expressway, and soon avoided almost all road travel except short rides with her husband, sitting stiffly in the back seat. She blamed herself for the accident, although nothing she did had caused it, and felt she should have done more for the injured passenger. She felt numb at family functions, snapped at her husband and could not concentrate on lesson planning. She began having a glass or two of alcohol at night to switch off, and the amount slowly increased.
Doctors do not go by a single symptom. Under the DSM-5-TR criteria, PTSD is diagnosed when a person has been exposed to a traumatic event and shows at least one intrusive symptom, at least one avoidance symptom, at least two symptoms of negative change in thinking and mood, and at least two symptoms of arousal and reactivity. These must last more than one month and cause significant distress or difficulty in daily life. Similar symptoms in the first month after the event may be diagnosed as acute stress disorder.
Why PTSD Often Goes Unnoticed
Many people with PTSD go without help for months or even years. PTSD is often linked in people’s minds only with soldiers or with very dramatic events, so a person who has had an accident, a medical emergency, a sudden loss or an assault may not think the word applies to them. Families often expect the person to move on once the physical injuries have healed, and the person may feel ashamed that they are still struggling.
The picture is also easy to mistake. Poor sleep, irritability, anxiety and low mood are common in many conditions, and PTSD can look like depression, an anxiety disorder or simply a bad temper. Some people use alcohol, sleeping pills or other substances to cope, which hides the real problem and can add an addiction on top of it. Symptoms can also begin weeks or months after the event, so the link to the trauma is easily missed. Left untreated, PTSD can lead to long absences from work, strained relationships, depression and substance use. The sooner it is recognised, the easier it is to treat.
In this case: Meera’s family assumed she was tired and that time would heal her. Her husband noticed the nightly drinking and the avoidance of travel, but he did not link them to the accident. Meera herself felt that because she had survived and her arm had healed, she had no right to feel this way. The turning point came when she returned to school and a heavy bench fell with a loud bang. She froze on the staircase and could not speak for several minutes. Her principal suggested she see a psychiatrist, and her family brought her to Calida Rehab.
Diagnosis: How PTSD Was Assessed at Calida Rehab
There is no blood test or scan that confirms PTSD. The diagnosis is made by a psychiatrist through a careful clinical assessment. At Calida Rehab this typically includes:
- A detailed clinical interview about the event, the symptoms, when they began and how they affect daily life. The person is not pushed to describe the trauma in detail at this stage.
- Structured tools, such as the PTSD Checklist for DSM-5 (PCL-5) and, where needed, the Clinician-Administered PTSD Scale (CAPS-5)
- Screening for depression and anxiety, using tools such as the PHQ-9 and GAD-7
- Screening for alcohol and other substance use, for example with the AUDIT questionnaire
- A physical and medical check to look at general health, sleep, pain and the effects of any injury, including any head injury
- A risk assessment for thoughts of self-harm or suicide, which are more common in people with untreated PTSD
- Input from a family member, with the person’s consent
That wider check matters. PTSD rarely comes alone. Depression, anxiety, sleep problems and alcohol or drug use often sit alongside it, and treating only one leaves the person struggling. See our page on anxiety disorder and our depression case study to see how these conditions can overlap.
Result in this case: Meera was diagnosed with PTSD of moderate to severe intensity, along with depressive symptoms, poor sleep and hazardous evening alcohol use. She had no thoughts of self-harm and no lasting effects of a head injury. Her PCL-5 score was well above the usual screening cut-off. For Meera, hearing that this was a recognised and treatable condition, and not a sign of weakness, was the first real relief.
Treatment Plan for PTSD
No single treatment suits everyone. At Calida Rehab the plan is built after the assessment, and the family is involved when the person agrees. Most plans combine the following.
Safety and stabilisation first. Before any work on the trauma itself, the team helps the person sleep better, feel safer and manage the strongest symptoms. Grounding skills and a regular daily routine are taught early.
Trauma-focused therapy as the core of treatment. Psychotherapy that works directly on the traumatic memory and the beliefs around it is the first-line treatment for PTSD. The main options are Cognitive Processing Therapy, Prolonged Exposure and EMDR. The choice is made with the person, based on their symptoms, preference and readiness.
Medicines, when needed. A psychiatrist may prescribe a medicine such as an SSRI antidepressant to reduce PTSD symptoms, low mood and anxiety. Medicines are reviewed regularly and are usually used together with therapy, not instead of it. Benzodiazepines are generally avoided because they do not treat PTSD and can get in the way of recovery.
Treatment of other conditions. Depression, anxiety, poor sleep and alcohol or substance use are treated alongside PTSD. If alcohol use needs supervised withdrawal, this is done safely under medical care. Read more on our detoxification page.
Family involvement. Families learn what PTSD is, why the person reacts the way they do, and how to support them without pushing them or avoiding the subject.
Lifestyle. Fixed sleep and wake times, regular exercise, balanced meals, less caffeine and no alcohol give the nervous system a better chance to settle.
In this case: Meera began with a stabilisation phase of about two weeks in a residential setting, mainly to restore her sleep, stop alcohol under medical supervision and start a medicine for her PTSD and depressive symptoms. Her husband and parents-in-law joined a family session in the first week. She then continued as an outpatient, with twelve sessions of Cognitive Processing Therapy over about eight weeks, along with regular reviews of her sleep and medicine. She chose this therapy after the team explained the options.
Therapies Used in This PTSD Case Study
The therapies below were part of Meera’s plan or were offered to her, and they are commonly used for PTSD.
- Cognitive Processing Therapy (CPT): helps the person look at stuck thoughts about the trauma, such as self-blame and feeling unsafe, and replace them with more balanced ones. This was Meera’s main therapy.
- Prolonged Exposure Therapy (PE): gradually and safely brings the person closer to trauma memories and avoided situations, with support, until they lose their power to frighten
- Eye Movement Desensitisation and Reprocessing (EMDR): helps the brain process a traumatic memory so that it feels less intense and less present
- Cognitive Behavioral Therapy (CBT): teaches skills to handle anxiety, poor sleep and negative thoughts. Read more on our CBT page.
- Grounding and sleep skills: breathing, grounding exercises and a fixed bedtime routine to calm flashbacks and nightmares
- Group and family therapy: sessions that reduce isolation and help families understand and support recovery. See our family therapy page.
Follow-Up Care After the First Phase
PTSD can have ups and downs, so care does not end when the first phase of treatment ends. Follow-up usually includes:
- Regular counselling sessions, with more frequent sessions in the first months and wider gaps later
- Repeat symptom checks, for example with the PCL-5, to track progress
- Review of sleep, mood, anxiety and any medicines, with the plan adjusted if needed
- Booster sessions around difficult dates or new triggers, such as the anniversary of the event
- A graded return to avoided situations such as travel, work or crowded places
- Review of alcohol or substance use, where this was part of the picture
- Continued involvement of the family, where the person agrees
A difficult phase does not mean treatment has failed. It is a signal to get support early. Our PTSD treatment page explains what ongoing care looks like.
Outcome: What Recovery Looks Like With PTSD
What changed for Meera over the first three months:
- Nightmares and flashbacks: nightmares fell from almost every night to once or twice a month. Flashbacks became rare, and she learned to use grounding skills when a memory came up.
- Avoidance: she began with short drives with her husband, then longer ones, and by the end of the third month she travelled on the expressway as a passenger.
- Alertness and mood: she startled less, her temper settled and her depressive symptoms eased.
- Sleep and alcohol: she slept through most nights without alcohol and did not return to drinking.
- Work: she went back to teaching and, with her principal’s support, returned to full classes in stages.
- Family: her husband said the tense, silent person in the house was slowly becoming herself again.
- Symptom score: her PCL-5 score fell below the usual screening cut-off.
It is worth being clear about what recovery means. It is not forgetting what happened. It is a person who can remember the event without being flooded by it, who sleeps, works and travels again, and who knows what to do when a hard day returns.
What the first six months of treatment usually look like
- Month 1: assessment, safety and stabilisation, better sleep, and starting medicine if needed.
- Months 2 and 3: trauma-focused therapy does most of the work. Family sessions continue.
- Months 4 to 6: gains settle in, with a graded return to avoided places and routines, and booster sessions if needed.
This is a general guide. Every person moves at a different pace.
Key Takeaways from This PTSD Case Study
- PTSD is a real medical condition, not a weakness. It can follow accidents, assaults, disasters and sudden losses, not only war.
- Symptoms can start weeks or months after the event and are easily mistaken for anxiety, depression or a bad temper.
- Trauma-focused therapy is the first-line treatment, and medicines can support it.
- Poor sleep, depression and alcohol use often sit alongside PTSD and need treatment too.
- Recovery does not mean forgetting. It means the memory stops controlling daily life.
