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

What is Allostasis and how does it relate to drug addiction?

The allostatic theory of drug abuse describes the brain’s reward system alterations as substance misuse progresses. Neural adaptations arising from the reward system itself and from the antireward system provide the subject with functional stability, while affecting the person’s mood.

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).

What is the difference between homeostasis and Allostasis?

Allostasis vs 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 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.

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).

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 happens during allostasis?

Introduction: Allostatic load refers to the cumulative burden of chronic stress and life events. It involves the interaction of different physiological systems at varying degrees of activity. When environmental challenges exceed the individual ability to cope, then allostatic overload ensues.
