Post-Traumatic Stress Disorder (PTSD) Overview

Posttraumatic stress disorder (PTSD) is a psychiatric disorder that may occur in patients who have experienced or witnessed a traumatic event such as a natural disaster, a serious accident, a terrorist act, war/combat, or rape or who have been threatened with death, sexual violence or serious injury.

Patients with posttraumatic stress disorder (PTSD) have intense, disturbing thoughts and feelings related to their experience that last long after the traumatic event has ended.

They may relive the event through flashbacks or nightmares; they may feel sadness, fear or anger; and they may feel detached or estranged from other people. Patients with PTSD may avoid situations or people that remind them of the traumatic event, and they may have strong negative reactions to something as ordinary as a loud noise or an accidental touch.

Signs and Symptoms of Post-Traumatic Stress Disorder (PTSD)

Most often the signs and symptoms of Post-Traumatic Stress Disorder (PTSD) begin within three months of the traumatic event. In some cases, however, they don’t begin until years later. The severity and duration of the illness can vary. Some people recover within six months, while others have it much longer.The intensity of PTSD symptoms may vary. You may have more symptoms when you feel stress in general, or when you encounter a specific reminder about what happened. Young children with PTSD may have delayed development in areas such as toilet training, motor skills, and language.

Following are the four main categories that the symptoms of PTSD often are grouped into:

  • Reliving: Patients with PTSD repeatedly relive the ordeal through thoughts and memories of the trauma. These may include flashbacks, hallucinations, and nightmares. They also may feel great distress when certain things remind them of the trauma, such as the anniversary date of the event.
  • Avoiding: The PTSD patient must avoid people, places, thoughts, or situations that may remind them of the trauma. This can lead to feelings of detachment and isolation from family and friends, as well as a loss of interest in activities that the person once enjoyed.
  • Increased arousal: These include excessive emotions; problems relating to others, including feeling or showing affection; difficulty falling or staying asleep; irritability; outbursts of anger; difficulty concentrating; and being “jumpy” or easily startled. The person may also suffer physical symptoms, such as increased high blood pressure (Hypertension) and heart rate, rapid breathing, muscle tension, nausea and diarrhea.
  • Negative cognitions and mood: Mood swings and negative conditions refers to thoughts and feelings related to blame, estrangement, and memories of the traumatic event.

 

Causes of Post-Traumatic Stress Disorder (PTSD)

Post-traumatic stress disorder (PTSD) can develop when someone go through, see or learn about an event involving actual or threatened death, serious injury or sexual violence.

Researchers are not sure why some people get Post-traumatic stress disorder (PTSD). As with most mental health problems, PTSD is probably caused by a complex mix of factors.

Following are some of the common causes that can contribute to PTSD:

  • Traumatic and stressful experiences, including the amount and severity of trauma you’ve gone through in your life
  • Inherited mental health risks, such as a family history of anxiety and depression.
  • Inherited features of a persons personality, or an individual’s temperament.
  • How the brain regulates the chemicals and hormones the body releases in response to stress.

Types of Post-Traumatic Stress Disorder (PTSD) Events

Following are the most common events leading to the development of PTSD:

  • Traumatic Event
  • Combat exposure
  • Childhood physical abuse
  • Sexual violence
  • Physical assault
  • Being threatened with a weapon
  • An accident
  • Violence

Many other traumatic events also can lead to PTSD, such as fire, natural disaster, mugging, robbery, plane crash, torture, kidnapping, life-threatening medical diagnosis, terrorist attack, and other extreme or life-threatening events.

 

Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections. 

We have samples available are cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.

Our company Bay Biosciences maintains and manages its own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types.

Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.

All our human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data.

This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information.

Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases. 

This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness. 

Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved at – 80°C.

Including fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.

Bay Biosciences is a global leader in collecting and providing human tissue samples according to the researchers specified requirements and customized, tailor-made collection protocols.

Please contact us anytime to discuss your special research projects and customized human tissue sample requirements.

Bay Biosciences provides human tissue samples (human specimens) from diseased and normal healthy donors which includes:

We can also procure most human bio-specimens and can-do special collections and requests of human samples that are difficult to find. All our human tissue samples are procured through IRB approved clinical protocols and procedures. 

In addition to the standard processing protocols Bay Biosciences can also provide human plasma, serum, PBMC bio-fluid samples using custom processing protocols, you can buy donor specific sample collections in higher volumes and specified sample aliquots from us.
