Heightened amygdala reactivity and increased stress generation predict internalizing symptoms in adults following childhood maltreatment.

Summary of "Heightened amygdala reactivity and increased stress generation predict internalizing symptoms in adults following childhood maltreatment."

Childhood maltreatment is one of the most potent predictors of future psychopathology, including internalizing disorders. It remains unclear whether heightened amygdala reactivity to threat and elevated stress exposure may be implicated in the pathogenesis and maintenance of internalizing disorders among individuals with a history of childhood maltreatment.

Amygdala reactivity as a marker of differential susceptibility to socioeconomic resources during early adulthood.

Models of differential susceptibility hypothesize that neural function may be a marker of differential susceptibility to context, but no studies have tested this hypothesis. Using a sample of 310 youn...

Child sex moderates the relationship between cortisol stress reactivity and symptoms over time.

Past work suggests that individual differences in stress reactivity have implications for the development of psychopathology; in particular, females' stress reactivity appears more closely tied to int...

Heightened HPA-axis stress reactivity and accelerated pubertal progression predicts depressive symptoms over 4-year follow up.

Pubertal timing has been suggested as biological factors implicated in the onset of depression in girls. This study aims to examine the prospective association between accelerated pubertal progression...

Why does stress aggravate itch? A possible role of the amygdala.

Stress is the exacerbating factor of itch across patients with chronic itch due to different origins. However, the precise mechanisms behind stress-induced exacerbation of itch remain unknown. Chronic...

Almond-shaped group of basal nuclei anterior to the inferior horn of the lateral ventricle of the brain, within the temporal lobe. The amygdala is part of the limbic system.

A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.

A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).

A microscopic imaging technique that takes advantage of the process of harmonic generation that occurs when photons interact to generate new photons of a different wavelength. In second harmonic generation, two photons of the same wavelength and frequency, such as from a LASER, interact inside a medium and are converted to a photon of twice the frequency and half of the wavelength of the two incident photons. The light signals captured are used to produce images that are dependent on the unique optical properties of the material.

Stress wherein emotional factors predominate.
