An Introduction to Modeling Behavioral Disorders and Stress
0 Views •
2023
Recently, it has been discovered that behavioral conditions such as, depression, anxiety and stress-response have a neurological basis. Understanding the biological underpinnings of these conditions may help scientists in developing more effective therapies to treat these disorders. Typically, rodent models are used in this field and behavioral scientists create these models using interventions like drug administration or surgery. It is important to understand how to create and evaluate rodent...

2025
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium. Symptoms and Behavioral Manifestations A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...

Source: Tendler, A., et al. How to Use the H1 Deep Transcranial Magnetic Stimulation Coil for Conditions Other than Depression. J. Vis. Exp. (2017)This video demonstrates the use of deep transcranial magnetic stimulation (dTMS) to alleviate symptoms of post-traumatic stress disorder, or PTSD. It begins by identifying reduced activity in the medial prefrontal cortex (mPFC) as a key factor contributing to the overactivation of the amygdala and heightened fear responses. By applying targeted...

Here we describe the detailed methodology required to conduct stress-enhanced fear learning (SEFL) experiments, a preclinical model of post-traumatic stress disorder, in both rats and mice. The model utilizes aspects of Pavlovian fear conditioning and freezing as an index of enhanced fear in rodents.

Modeling Social Stress

2023
Stress negatively affects our quality of life. In particular, some individuals experience social stress when placed in a social environment that they are unfamiliar with or have difficulty adjusting to. Since it is hard to examine mechanisms of social stress in humans, modeling this condition in animals may help scientist in developing new therapies for treating this commonly encountered problem. This science education video begins by discussing the known anatomy and physiology behind stress...
FAQs
Symptoms may persist when stress-response systems remain activated or when memories of an event continue to trigger fear and arousal. These reactions can also promote avoidance, mood changes, or altered behavior, creating ongoing distress even after the original threat has ended. Recognizing these interacting processes helps clinicians connect reported experiences with continuing functional impairment.
These conditions are distinguished by the relationship between the stressor, the person’s symptom pattern, and how long symptoms persist. Clinical evaluation considers duration alongside fear, arousal, avoidance, mood, behavior, and daily functioning. This comparison helps clinicians determine which disorder best corresponds to the observed response rather than relying on the stressful event alone.
Assessment focuses on patterns that may include fear, heightened arousal, avoidance, and changes in mood or behavior. Clinicians also examine whether these symptoms cause persistent distress or interfere with daily functioning. Considering the full pattern is important because an isolated reaction may provide less information than the combination, duration, and practical impact of symptoms.
Functional impairment shows how symptoms affect a person’s everyday life, rather than describing distress in isolation. Clinicians consider this impact together with clinical history, symptom patterns, and duration. The information helps distinguish clinically significant problems from temporary reactions and supports decisions about recognition, treatment planning, and the level of ongoing care needed.
A clinical history places symptoms in context by examining relevant experiences, their timing, and the reactions that followed. Clinicians then compare that history with symptom patterns, duration, and effects on functioning. This structured review supports recognition of conditions such as acute stress disorder, post-traumatic stress disorder, or adjustment disorder without reducing assessment to a single symptom.
Treatment may include psychotherapy, stress-management strategies, and, when appropriate, medication. The selection depends on the person’s clinical presentation and the distress or impairment identified during evaluation. These approaches aim to address symptoms and support functioning, while trauma-informed care helps ensure that recognition and treatment respond respectfully to the person’s experiences.
Early recognition can identify persistent distress and impaired functioning before difficulties remain unaddressed for longer periods. Trauma-informed care provides a framework for responding to people whose symptoms are connected with overwhelming or traumatic experiences. Together, they support more appropriate evaluation, respectful communication, and timely consideration of psychotherapy, stress-management strategies, or medication when suitable.
