Studying the brain has been an affective result in finding out the various neurochemicals that are involved with PTSD. Brain imaging systems nowadays focus on two brain structures, the amygdala and the hippocampus. The amygdala is involved with how we learn about our fear and hippocampus plays a role with our memory formation. Some research focuses on a hormonal system known as hypothalamic-pituitary

Research has indicated that people who have experienced and extreme amount of stress or traumatic event sometimes have a smaller hippocampus region of the brain in adults with chronic PTSD and early childhood trauma. This is the part of the brain that is responsible for memory. The reduction in size may be caused by a combination of the environment and genetics (NARSAD.com). People who are diagnosed with this disorder are more likely to have trouble with relationships, smoke cigarettes, abuse drugs and or alcohol use. If PTSD is left untreated it can have devastating lasting effects.

Post-traumatic stress disorder, otherwise known as PTSD is a mental health condition triggered by a terrifying event, either by experience or witness, it can trigger flashbacks, nightmares, severe anxiety, and as well as uncontrollable thoughts about the

There have been many diagnoses of PTSD in American soldiers. As Mark Thomas said in a magazine article, “The National Academy of Sciences have report estimated that up to 20% of 2.6 million US men and women who have served in Afghanistan and Iraq may have it (PTSD)”(Thomas). This quote expresses that nearly 520,000 US families have been affected by this disorder. It also shows that PTSD has become a large enough issue that more and more people and

PTSD, or Post-traumatic Stress Disorder, is a psychiatric disorder that can occur following the experience or witnessing of a life-threatening events such as military combat, natural disasters, terrorist incidents, serious accidents, or physical or sexual assault in adult or childhood. Most survivors of trauma return to normal given a little time. However, some people will have stress reactions that do not go away on their own, or may even get worse over time. These individuals may develop PTSD. People who suffer from PTSD often relive the experience through nightmares and flashbacks, have difficulty sleeping, and feel detached or estranged, and these symptoms can be severe enough and last long enough to significantly impair the person’s daily life.

Post-Traumatic Stress Disorder or PTSD is a mental health condition that is generally classified as an anxiety disorder. It is often caused by a traumatic events or emotional trauma in one’s life that leads to terrifying flashbacks, nightmares and extreme anxiety. The main cause of this disorder is the conscious and subconscious fear-memories that have developed. In essence the ‘fight or flight” response that we all have is severely damaged, even when not in a stressful or dangerous situation those suffering from PTSD may feel stressed and in danger.

Post-Traumatic Stress Disorder (PTSD) is a psychiatric sequel to a stressful event or situation of an exceptionally threatening or catastrophic nature. It develops after a person is involved in a horrifying ordeal that involved physical maltreatment or the threat of physical harm. These events can include combat or military experience, abuse during childhood or adulthood (physical or sexual), terrorist attacks, serious accidents or natural disasters. This person may have been the one that was harmed, witnessed a harmful event or had a loved one who was harmed. It is normal for the body’s fight or flight mechanism to engage in times of danger. With a person who has PTSD, that mechanism is damaged and the person feels this even when they are not in danger. Symptoms can be categorized into four different areas – re-experiencing symptoms (flashbacks, bad dreams, frightening thoughts) , avoiding situations that remind the person of the event, negative changes in beliefs and feelings (may be fear, guilt, shame or losing interest in those activities that once were enjoyable) and hypervigilence (always feeling keyed up, trouble concentrating or sleeping). There are also feelings of hopelessness, despair, depression or anxiety, alcohol or substance abuse, physical symptoms or chronic pain and problems with employment and relationships.

The freedoms Americans enjoy come at a price; brave military men and women often foot the bill. Many men and women pay with their lives; others relive the sights, sounds, and terror of combat in the form of PTSD. Several causes and risk factors contribute to the development of PTSD. Combat-related PTSD appears slightly different than traditional PTSD. History tells of times when soldiers diagnosed with PTSD were viewed as “weak.” Resources have not always been available to struggling soldiers. The adverse symptoms of PTSD on soldiers and their families can be crippling.

PTSD is defined as an "anxiety disorder that can occur after you have been through a traumatic event. A traumatic event is something horrible and scary that you see or happens to you” (United States). In these types of events one can feel that they are not in control of what is going on around them and may feel helpless or in great danger. The Department of Veterans Affairs has listed various life threatening events that can evolve into PTSD. These events include but are not limited to "Combat or Military exposure, child sexual or physical abuse, terrorist attacks, sexual or physical assault, serious accidents, such as a car wreck, natural disasters, such as a fire, tornado, hurricane, flood, or earthquake” (United States).

Brian Albrecht, in his article "Families share the pain of veterans' PTSD" (2013), informs the reader of the effects of ptsd war veterans on their family, children and spouses that may cause higher levels in stress and anxiety. Brian supports his assertion by providing the reader with factual evidence of PTSD war veterans from credible resources, such as "This ‘secondary PTSD’ can include distress, depression and anxiety, said the Department of Veterans Affairs' National Center for PTSD" ( Albrecht). The purpose of this article is to inform the reader of the negative effects that ptsd war veterans may inflict in their family and children, in order to treat and prevent higher levels of stress and anxiety throughout the family. The authors creates

Posttraumatic Stress Disorder (PTSD) develops after a terrifying ordeal that involved physical harm or the threat of physical harm. The person who develops PTSD may have been the one who was harmed or the person may have witnessed a harmful event that happened to loved ones or strangers.

Some of the theories that can cause PTSD are when a person goes through, sees or learns about an event that causes intense fear, helplessness, or horror. There are some researchers that think that a person is more likely to develop PTSD than others when their risk of anxiety and depression increases, a person’s life experiences, a person’s temperament and/or the way the brain regulates the chemicals and hormones their body releases in response to stress. There are several risk factors associated with PTSD. Some of them being female, experiencing intense or long lasting trauma, having experienced other trauma earlier in life, having other mental health problems, and/or lacking a good support system. PTSD can disrupt a person’s everyday life-from their jobs to their enjoyment of everyday activities. There are three groups of medications that may help someone with PTSD-antipsychotics, antidepressants and antianxiety. There is one medication that has been shown to decrease the nightmares of PTSD victims.-prazosin. There are two other types of therapy that have been shown to help in the treatment of PTSD-exposure therapy-especially virtual exposure therapy-where a person is virtually exposed to the situation that initially caused their PTSD-and eye movement

Extensive neuroimaging studies on the brains of PTSD patients show that several regions differ structurally and functionally from those of healthy individuals. The amygdala, the hippocampus, and the ventromedial prefrontal cortex play a role in triggering the typical symptoms of PTSD. These regions collectively impact the stress response mechanism in humans, so the PTSD victim, even long after his experiences, continues

PTSD is an anxiety disorder that can develop after exposure to a terrifying event in which grave physical harm occurred or was threatened. Traumatic events that may trigger this anxiety include violent personal assaults, natural or human-caused disasters, accidents, or military combat.

The amygdala is known to learn from exposure to fear and store assessment of threat–related stimuli. The prefrontal cortex is involved in extinction and the retention of fear and is connected to the amygdala. Finally, the hippocampus encodes the context during fear learning process and sends it to the amygdala. People with PTSD have hyper-activity in the amygdala, while having hypo-activity in the prefrontal cortex and there is reduction of the hippocampus volume. This reduction may limit proper evaluation and categorization of the experience. A study on Vietnam soldiers revealed that lesions in the amygdala and prefrontal cortex resulted in the absence of PTSD. To get further into the molecular level studies been done on the hormonal system. “Stress is known to contribute to the pathogenesis of a variety of disorders, including the majority of psychiatric like major depression and posttraumatic stress disorder.” (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3825244/pdf/DM30-02-343616.pdf). Research has revealed evidence that a hormonal system known as the hypothalamic-pituitary-adrenal (HPA) axis is the one that gets disrupted in people with PTSD. The hormonal system is involved in normal stress reactions, so the disruption of this system in people with PTSD creates this “false alarm”. It has been suggested by some scientist that the dysfunction of the HPA system results in hippocampal damage in people with PTSD. Damage in the hormones is caused by damage to
