What neurotransmitters are involved in PTSD?

the catecholamine family of neurotransmitters, including dopamine (DA) and norepinephrine (NE), derive from the amino acid tyrosine. Increased urinary excretion of DA and its metabolite has been reported in patients with PTSD. Further, mesolimbic DA has been implicated in fear conditioning. There is evidence in humans that exposure to stressors induces mesolimbic DA release, which in turn could modulate HPA axis responses. Whether or not DA metabolism is altered in PTSD remains unclear, though genetic variations in the DA system have been implicated in moderating risk for PTSD (see below). NE, on the other hand, is one of the principal mediators of autonomic stress responses through both central and peripheral mechanisms. The majority of CNS NE is derived from neurons of the locus ceruleus (LC) that project to various brain regions involved in the stress response, including the prefrontal cortex, amygdala, hippocampus, hypothalamus, periaqueductal grey, and thalamus. In addition, there is evidence for a feed-forward circuit connecting the amygdala and hypothalamus with the LC, in which CRH and NE interact to increase fear conditioning and encoding of emotional memories, enhance arousal and vigilance, and integrate endocrine and autonomic responses to stress. Like other stress pathways, this cascade is inhibited by glucocorticoids,18which serve as a “brake” for the system. In the periphery, stress-induced sympathetic nervous system activation results in the release of NE and epinephrine from the adrenal medulla, increased release of NE from sympathetic nerve endings, and changes in blood flow to a variety of organs as needed for fight-or-flight behavior. The NE effects arc mediated via postsynaptic α1β1, and β2, receptors, whereas another NE-activated receptor, the α2receptor serves as a presynaptic autoreceptor inhibiting NE release. Because of its multiple roles in regulating arousal and autonomic stress responses, as well as promoting the encoding of emotional memories, NE has been a central focus of many studies investigating the pathophysiology of PTSD.

What are the neurochemical features of PTSD?

Core neurochemical features of PTSD include abnormal regulation of catecholamine, serotonin, amino acid, peptide, and opioid neurotransmitters , each of which is found in brain circuits that regulate/integrate stress and fear responses. Of note, catecholamine and serotonin (as well as acetylcholine) dysregulation is also found in patients diagnosed with TBI, presumably as a result of diffuse axonal injury.

What is the role of 5HT in the brain?

5HT has roles in regulating sleep, appetite, sexual behavior, aggression/impulsivity, motor function, analgesia, and neuroendocrine funtion. Not surprisingly, given its connectivity and broad homeostatic role, 5HT has been implicated in the modulation of affective and stress responses, as well as a role in PTSD. Although the mechanisms are not entirely clear, the effects of 5HT on affective and stress responses vary according to stressor intensity, brain region, and receptor type. It is believed that 5HT neurons of the dorsal raphe mediate anxiogenic effects via 5HT2receptors through projections to the amygdala and hippocampus. In contrast, 5HT neurons from the median raphe are thought to mediate anxiolytic effects, facilitate extinction and suppress encoding of learned associations via 5HT1Areceptors. Chronic exposure to stressors induces upregulation of 5HT2and downregulation of 5HT1Areceptors in animal models. Further, 5HT1Aknockouts exhibit increased stress responses.

What is psychological trauma?

Psychological trauma can result from witnessing an event that is perceived to be life-threatening or to pose the potential of serious bodily injury to self or others. Such experiences, which are often accompanied by intense fear, horror, and helplessness, can lead to the development of, and are required for the diagnosis of, post-traumatic stress disorder (PTSD).1It was originallythought that PTSD represented a normative response, at the extreme end of a response continuum, the severity of which related primarily to trauma/stressor intensity. However, it has become clear over time that the response of an individual to trauma depends not only on stressor characteristics, but also on factors specific to the individual.2For the vast majority of the population, the psychological trauma brought about by the experience of profound threat is limited to an acute, transient disturbance. Though transient, such reactions can be quite unpleasant and are typically characterized by phenomena that can be grouped for the most part into three primary domains: (i) reminders of the exposure (including flashbacks, intrusive thoughts, nightmares); (ii) activation (including hyperarousal, insomnia, agitation, irritability, impulsivity and anger); and (iii) deactivation (including numbing, avoidance, withdrawal, confusion, derealization, dissociation, and depression). As these reactions are self-limiting by definition, in general they provoke minimal functional impairment over time. On the other hand, for a significant minority of the population, the psychological trauma brought about by the experience of profound threat leads to a longer-term syndrome that has been defined, validated, and termed PTSD in the clinical literature. PTSD is often accompanied by devastating functional impairment.

What is the main neurotransmitter in the brain?

Amino acids . γ-Aminobutyric acid (GABA) is the principal inhibitory neurotransmitter in the brain. GABA has profound anxiolytic effects and dampens behavioral and physiological responses to stressors, in part by inhibiting the CRH/NE circuits involved in mediating fear and stress responses.

Is PTSD genetic or psychological?

Although the biological, psychological , and social ramifications of PTSD have been under scientific scrutiny for some time now, and treatment has improved dramatically, much remains unknown about this condition and controversy persists in both the neuroscientific as well as the clinical/treatment literature. In this text, we review the neurobiological impact of psychological trauma from the perspective that genetic, developmental, and experiential factors predispose certain individuals to the development of PTSD. More specifically, we review the current database as pertains to biological markers of PTSD and the possibility that some biological markers may not be acquired but, rather, may in fact predate trauma until functionally “unmasked” by stress. Where relevant, we also make note of similarities between PTSD and TBI, which extend beyond wellknown signs and symptoms (such as irritability and social withdrawal) to include abnormalities in the same neurobiological systems. Lastly, the article includes a short section on basic considerations for future direction. Ideas put forth in this communication are done so in the interest of developing a consistent model for conceptual purposes. It is recognized at the outset that numerous inconsistencies can be found in the literature that highlight the multifactorial and complex nature of this field.

Is PTSD a reflexive nervous system?

The classic fight-or-flight response to perceived threat is a reflexive nervous phenomenon thai has obvious survival advantages in evolutionary terms. However, the systems that organize the constellation of reflexive survival behaviors following exposure to perceived threat can under some circumstances become dysregulated in the process. Chronic dysregulation of these systems can lead to functional impairment in certain individuals who become “psychologically traumatized” and suffer from post-traumatic stress disorder (PTSD), A body of data accumulated over several decades has demonstrated neurobiological abnormalities in PTSD patients. Some of these findings offer insight into the pathophysiology of PTSD as well as the biological vulnerability of certain populations to develop PTSD, Several pathological features found in PTSD patients overlap with features found in patients with traumatic brain injury paralleling the shared signs and symptoms of these clinical syndromes.

How to deal with PTSD?

Traumatic events can be very difficult to come to terms with, but confronting and understanding your feelings and seeking professional help is often the only way of effectively treating PTSD . You can find out more in the links below, or here.

How does PTSD affect the brain?

The extreme stress and reactions from PTSD and C-PTSD results in acute and chronic changes in neurochemical systems and specific brain regions, which result in longterm changes in brain “circuits,” involved in the stress response. This is why replacing negative connections and cycles, or finding a way to bypass them, can take a heavy investment of time and therapy.

What are the brain structures that are affected by PTSD?

This is because neuroanatomical studies have identified changes in major brain structures of those with PTSD — the amygdala and hippocampus – showing that there are significant physical changes within the brain as a result of trauma. These brain changes from PTSD, particularly if not diagnosed yet, can make life seem very confusing, ...

How does CBT work?

CBT can work by strengthening connections between the amygdala and brain regions that are involved in cognitive control, providing more control of processes that are dysregulated as a result of PTSD.

How has modern science enabled us to get a far clearer picture of the brain and in fact the whole neurological system

It has become possible to map and measure the different development paths that each human brain follows. Our age and the things that happen to us each day naturally dictate microscopic changes to our brain’s structure.

Which part of the brain is responsible for a response to stress?

The amygdala is the part of the brain that formulates a response to stress. It takes this ‘alert’ from sensory input – such as something you see or hear – and connects it to something from your memory.

Is PTSD a mental illness?

The science and biology of PTSD. In the study and science of Post Traumatic Stress Disorder it’s important to understand that PTSD is considered to be a psychological injury rather than a mental illness.

cortisol. hormone that helps the body respond to stressors, inducing the fight-or-flight response. post-traumatic stress disorder (PTSD) anxiety disorder characterized by (1) repeated mental images of experiencing a traumatic event, (2) emotional numbing and detatchment, and (3) hypervigilance and chronic arousal.

Can traffic accidents cause PTSD?

A. Common events, such as traffic accidents, are rarely associated with PTSD.

How does CBT help with PTSD?

In the treatment of PTSD, CBT usually involves prolonged, imaginal exposure to the patient's memory of the trauma, and in vivo exposure to various reminders of the trauma, as well as cognitive restructuring and anxiety management techniques.[ 77] The efficacy of CBT in treating chronic PTSD has led researchers to question whether this approach may also be useful as an early intervention. Most of these studies have tested CBT in the first weeks or months of trauma exposure, consisting of approximately 4–5 sessions with patients who meet criteria for acute stress disorder. As one example, a study by Bryant et al.[78]examined the efficacy of CBT and anxiety management in the treatment of ASD. Civilian trauma survivors were given five sessions of either prolonged exposure (PE), a combination of exposure and anxiety management, or supportive counseling within 2 weeks of their trauma. Results indicated that fewer individuals in the exposure (14%) and exposure plus anxiety management (20%) conditions met the criteria for PTSD following treatment than those in the supportive counseling group (56%). Results of this study suggested that PTSD can be prevented by early provision of CBT and that exposure may be a critical component in the treatment of ASD.[78] Another study that applied cognitive-behavioral techniques to a sample of female assault survivors found that the intervention produced lower rates of PTSD and anxiety compared to supportive counseling at a 2-month follow-up.[79] Other studies have documented similar results for the efficacy of CBT applied in the first month after trauma exposure in preventing chronic PTSD,[80,81]or at accelerating recovery.[79] In addition to these early intervention studies, the use of exposure and other cognitive-behavioral techniques implemented several weeks or months after the initial trauma have also produced positive findings. [82–85]Bryant et al.[86]conducted a study that dismantled exposure versus cognitive restructuring approaches and found that those who received exposure therapy were less likely to meet criteria for PTSD and to have achieved full remission of symptoms at follow-up. In summary, interventions that were delivered individually, in multiple sessions, to patients with severe symptoms, in the early weeks of trauma exposure, have typically been effective at reducing the incidence of PTSD compared to no treatment or supportive counseling control groups, with exposure techniques potentially being key in producing these results. These intervention approaches highlight the potential benefit of CBT in recently traumatized individuals, especially exposure techniques.

What are the interventions for PTSD?

A memory-structuring intervention aimed at helping trauma survivors organize their memory of the traumatic event was developed by Gidron et al.[62]A small randomized controlled study of traffic accident victims indicated lower PTSD symptoms among participants who received the memory-structuring intervention. A follow-up study aimed at replicating these findings found a gender-specific effect, where female participants experienced reduced PTSD symptoms in the intervention group, but male participants did not.[63] These inconsistent findings point to the need for further replication, especially as both studies utilized small sample sizes.

What is a Battlemind PD?

For example, Battlemind PD is a group-based intervention designed for a military population exposed to combat trauma. In contrast to PD, this program does not emphasize recounting the traumatic event, and instead focuses on normalizing trauma reactions and educating participants on common problems (e.g., sleep, anger difficulties) that they may experience or see in their fellow unit members as a result of the identified trauma.[67] Adler et al.[68]documented some preliminary support suggesting that postdeployment participation in the Battlemind program was associated with fewer PTSD and depression symptoms compared to a stress education group, particularly among soldiers with high-combat trauma exposure.

What are the potential predictors of PTSD?

Research has been devoted to the study of potential predictors of PTSD to identify those most vulnerable following exposure to a traumatic event. Meta-analyses have identified prior trauma histories, family psychiatric history, perceived life threat, poor social support, and peritraumatic emotional responses as risk factors for PTSD. [16,17]Approximately one-third of the vulnerability to develop PTSD is genetically heritable and the remaining risk is primarily environmentally determined. [18,19]Thus, research that can identify potential candidate genes that predict the development of PTSD may offer a more efficient way of identifying at risk trauma survivors and determining who is most likely to require and to benefit from early intervention. For example, it was recently demonstrated that polymorphisms within the FKBP5 gene (which regulates HPA axis reactivity) interact with a history of child abuse to predict adult PTSD symptoms. [20–24]Other alterations of the HPA axis, including hyperactivity of corticotropin-releasing hormone receptor (CRHR1) in neurons,[25]have been demonstrated to be a prominent feature of PTSD. Specific CRHR1 polymorphisms moderate the effect of child abuse on the risk of adult depressive symptoms[26]and PTSD.[27] To the extent that CRHR1 polymorphisms function as a marker of CNS stress reactivity, variants may be valuable as vulnerability factors that interact with stress exposure to impact PTSD and may define a PTSD-depression phenotype.

How long does PTSD last?

PTSD often exhibits a chronic course, with as many as 40% continuing to exhibit significant symptoms of the disorder 10 years after its onset.[5] Psychiatric comorbidity is between two and six times more likely to occur in individuals with PTSD. [6,7]Increased risk for physical health problems and visits to the doctor are observed as well, with PTSD often associated with significant functional impairment across a variety of domains. [8–14]With respect to the financial costs associated with this disorder, Greenberg et al.[15]found that through work impairment, hospitalization, and health visits, PTSD was responsible for higher costs than any of the other anxiety disorders. These considerations underscore the devastating impact of PTSD and illustrate the urgent need for interventions that may prevent the development of the disorder.

What is behavioral activation intervention?

The behavioral activation intervention involved multiple (i.e., four to six) office-based psychotherapy sessions. Exclusion criteria included a history of substance abuse or dependence, alcohol dependence, pre-injury PTSD or depression, ongoing intimate partner violence, ongoing lawsuits, or patients with extended intensive care unit stays. Screening procedures required patients to be diagnosed with PTSD in order to be included. Of particular note, the intervention focused exclusively on behavioral activation, and did not address competing demands that might serve as barriers to participation in intervention activities. Intervention patients in the collaborative care trial received stepped care. Stepped collaborative care combined care management and motivational interviewing targeting treatment retention and engagement with psychopharmacological and exposure-based CBT interventions specifically targeting PTSD symptom reduction. Treatment began with each injured intervention patient being met at bedside in the surgical ward by a masters in social work (MSW) care manager. Treatment delivery occurred in acute care settings (e.g., surgical outpatient clinic follow-up appointments), in the community, or over the telephone. There were few intervention specific exclusions and all patients with active alcohol or drug abuse/dependence were included. In both trials, patients assigned to the control condition received care as usual.

Why is secondary prevention important for PTSD?

High rates of trauma exposure and the impact and cost of PTSD highlight the need for secondary prevention that can accelerate recovery and decrease the severity of traumatic stress reactions in order to prevent development of chronic PTSD. As this review suggests, progress has been made in identifying who is most at risk for developing PTSD and in developing effective interventions, but a considerable amount of research is still needed to replicate these preliminary findings and disseminate interventions to clinicians working with trauma survivors.

What happened in Chapter 5 of Abnormal Psychology?
