This study aimed to investigate the occurrence and duration of stress sensitization prospectively following a major disaster. Method Residents affected by a fireworks disaster (n=1083) participated in surveys 2–3 weeks (T1), 18–20 months (T2) and almost 4 years (T3) after the disaster. There are notable shortcomings in several important topics: measurement and evaluation of chronic stress and depression; exploration of potentially different processes of stress and depression associated with first-onset versus recurrent episodes; possible gender differences in exposure and reactivity to stressors; testing kindling/sensitization processes; longitudinal tests of diathesis Sensitization processes are remediable or preventable risk factors for a poor illness outcome and deserve increased clinical, public health, and research attention in the hopes of making the recurrent unipolar and bipolar affective disorders less impairing, disabling, and lethal by suicide and increased medical mortality. The stress response is our natural cognitive, emotional, motivational, bodily, behavioral and social response to a danger, or what we might more generically call a ‘stressor.’ Take for example, thousands of years ago, we would have been likely living on the savannas of Africa and we would have faced various threats, such as the possibility of being attacked by lions. If 5-HT 1A autoreceptor desensitization contributes to stress-induced sensitization of DRN 5-HT neurons as hypothesized, then an increase in 5-HT 1A autoreceptor number in the DRN after exercise could help resist DRN sensitization by simply providing a greater number of autoreceptors.

That is, individuals may become sensitized to stress, rendering them more vulnerable to experiencing depression in the face of less and less severe stressors (Post, 1992; Monroe & Harkness, 2005). This theory, called the stress sensitization model, This stress sensitization may be critical in the development or relapse of schizophrenia.

Research involving depressed populations has supported early adversity sensitization (Hammen et al., 2000). However, a few studies have investigated the In contrast to stress sensitization, inhibited children with early trauma plus recent stressors did not show especially high mid-childhood internalizing difficulties. Conclusions: Early life trauma The authors tested a stress-sensitization version of a diathesis-stress approach to depression. In a 2-year longitudinal follow-up design, exposure to stressful life events was examined in young women in the transition to adulthood. The authors hypothesized that those who had experienced one or more significant childhood adversities would have a Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response.

Research involving depressed populations has supported early adversity sensitization (Hammen et al., 2000). However, a few studies have investigated the In stress sensitization, early life stress and stress occurring in adulthood can each serve to trigger episodes or leave behind neurobiological vulnerabilities that increase sensitivity to future stress. Stress sensitization is a specific example of diathesis-stress wherein early adversity represents a general diathesis, and later or prolonged exposure to stress is required to trigger Stress sensitization can be extremely harmful it can trigger high blood pressure, diabetes, ulcers, asthma and digestive and lung ailments among others. We may respond to stress as we do an allergy.
The stress response is normal, healthy, and necessary alarm. If sustained there may be a risk of illness and disease.

In addition, to address empirical and conceptual questions about stress effects, the moderating effect of anxiety disorder history was also explored. This examination was conducted in a Sensitization definition, the state or process of being sensitized.

The neural correlates of a negative mood might be impaired, resulting in stress sensitization and difficulties in social adjustment (Dr. Habel). Urbanicity is associated with later schizophrenia. Psychophysiological factors, such as the stress-response, are also apt to play a role in the development of central sensitization. Direct experimental evidence on animals 23, 24 and humans, 25, 26 as well as prospective studies on humans, 27 have shown a relationship between stress and lowering of pain thresholds. Stress sensitization may explain the persistence or progression of distress over time following extreme stressor exposure.
We can be acutely sensitive or sensitized to stress. When this happens the smallest imitation of stress might trigger a series of chemical brain and body reactions that may 'eat' us inside. In laymans' language, stress sensitization is the equivalent to the effect of a pollen allergy. Repeated social defeat (RSD) stress in mice increases the release of monocytes from the bone marrow that are recruited to the brain by microglia. These monocytes enhance inflammatory signaling and augment anxiety.
