What is allostatic load quizlet?

Allostatic load refers to the cumulative effect of our body trying to re-establish allostasis in response to frequent and intense stressors. However, allostatic overload is when the demands of the stressor exceed the body’s ability to repeatedly adapt, the person is no longer able to meet demands.

What is allostatic load example?

Allostatic load and allostatic overload refers to the cumulative result of an allostatic state. For example, fat deposition in a bear preparing for the winter, a bird preparing to migrate or a fish preparing to spawn are examples of animals experiencing an allostatic load.

Which of the following best describes the meaning of allostatic load?

Allostatic load is the wear and tear on the body which accumulates as an individual is exposed to repeated or chronic stress. … It represents the physiological consequences of chronic exposure to fluctuating or heightened neural or neuroendocrine response which results from repeated or prolonged chronic stress.

What is allostatic load hypothesis?

Allostatic load refers to the long-term effects of continued exposure to chronic stress on the body. … The theory behind allostatic load suggests that the acute stress response in human bodies becomes maladaptive when it is consequently activated in response to chronic stressors.

What is the difference between Allostasis and homeostasis quizlet?

Homeostasis is a state of equilibrium, of balance within the organism, whereas allostasis is the overall process of adaptive change necessary to maintain survival and well-being.

How do you calculate allostatic load?

Allostatic load is then determined by summing the number of biomarkers within the high-risk quartile for each individual (Fig. 2). Each animal’s allostatic load will lie between 0 (no biomarkers in the high-risk quartile) and the number of biomarkers included (all biomarkers in the high-risk quartile).

What is Allostasis in psychology?

Allostasis is defined as the process of maintaining homeostasis through the adaptive change of the organism’s internal environment to meet perceived and anticipated demands.

What is Allostasis and homeostasis?

Allostasis is the process of achieving stability through physiological, behavioral changes during the changing conditions. Homeostasis is simply the maintaining stable internal environment in an organism despite the changes that occur in the external environment.

What is Allostasis in addiction?

Allostasis from the addiction perspective is defined as the process of maintaining apparent reward function stability by changes in brain reward mechanisms.

Which of the following best defines allostasis?

Allostasis is defined as the process whereby an organism engages adaptive changes that defend the level of a regulated parameter in response to new or changing environments – before the regulated parameter itself has changed.

Which of the following is an example of allostasis?

As an example, we can think of heart rate and blood pressure. … As soon as you get up in the morning and go for a jog, your heart rate and blood pressure will go up. The fact that your body varied its parameters to match the new environment (jogging vs. sleeping) is an example of allostasis.

What is the importance of allostatic load?

In summary, allostatic load provides an overall and a body system-specific mechanistic link between exposures to stressors and health outcomes that may help explain health disparities among minority populations.

What is an allostatic state?

An allostatic state is defined by chronic deviation of regulatory systems away from their normal state of operation, to establish a new set point (Koob and Le Moal, 2001). The limbic system, including the hippocampus and amygdala, is evidenced to mediate many neurodevelopmental consequences of childhood abuse.

Who created the theory of allostasis?

More specifically, Sterling and Eyer coined the term allostasis to reflect the process whereby in order to be adaptive, organisms must be able to change the defended levels of one or more regulated parameters as needed to adjust to new or changing environments.

What is the implication of allostasis for stress management?

Allostatic systems promote adaptation to stressful experiences and are generally most useful when rapidly mobilized and terminated. When they are prolonged or not terminated promptly, allostatic systems undermine mental and physical health—primarily because of their effects on brain plasticity (see below).

During which stage of the general adaptation syndrome gas does allostatic load occur?

Alarm is the first stage and is characterized by fight or flight response. Exhaustion is the last stage when the body cannot bring itself back to homeostasis/allostasis. Allostatic load is the wear and tear effects on the body from stress.

During which stage of the general adaptation syndrome gas does allostatic load occur quizlet?

GAS is the body’s way of adapting and dealing with a perceived stressor or stressors. The resistance stage of GAS corresponds with a person having an increased allostatic load, while the exhaustion phase corresponds with the concept of allostatic overload.

What is the term for anticipating possible stressors before they happen and acting to minimize their effects?

Proactive coping is a specific type of adaptive strategy that attempts to anticipate a problem before it begins and prepare a person to cope with the coming challenge. Negative coping strategies might be successful at managing or abating stress, but the result is dysfunctional and non-productive.

What is allostatic compensation?

Allostasis provides compensation for various problems, such as in compensated heart failure, compensated kidney failure, and compensated liver failure. However, such allostatic states are inherently fragile, and decompensation can occur quickly, as in acute decompensated heart failure.

How does allostatic load affect health?

Allostatic load is the “wear and tear” of the body resulting from the repeated activation of compensatory physiological mechanisms in response to chronic stress. Allostatic load can significantly affect the aging process and result in reduced longevity, accelerated aging, and impaired health.

What is allostatic load and how does it help us understand racial disparities in health?

The concept of allostatic load as a lifelong cumulative measure of physiologic dysfunction resulting from stress suggests that efforts within the health care system to reduce secondary biomarkers (eg lower blood pressure and glycated hemoglobin) with medications and diet is one approach to reduce racial disparities in …

Are allostasis and homeostasis the same?

Allostasis is sometimes defined as the process for actively maintaining homeostasis. … The endpoint (dynamic stability) is homeostasis. The processes involved in achieving homeostasis are called homeostatic mechanisms.

What are Neuroadaptations?

Neuroadaptations are anatomic or physiologic changes that attempt to maintain homeostasis and occur following the use of cocaine, methamphetamine (Meth), and 3,4-methylenedioxymethamphetamine (MDMA).

What is incentive sensitization theory?

The incentive-sensitization theory posits the essence of drug addiction to be excessive amplification specifically of psychological ‘wanting’, especially triggered by cues, without necessarily an amplification of ‘liking’.

What is the biopsychosocial model of addiction?

The biopsychosocial model of addiction states that genetic/ biological, psychological, and sociocultural factors contribute to substance consumption and should be taken into account for its prevention and treatment (Becoña, 2002; Skewes & González, 2013).
