The availability of the dopamine receptor D2 plays a role in self-administration and the reinforcing effects of cocaine and other stimulants. This approach is likely to reduce the severity of a relapse than to prevent one from occurring altogether. In medicine, relapse or recidivism is a recurrence of a past (typically medical) condition.

A common example of contingency management is a token or voucher system, in which abstinence is rewarded with tokens or vouchers that individuals can redeem for various retail items.
Stress-induced craving is also predictive of time to relapse. , To self-administer the drug of interest the animal is implanted with an intravenous catheter and seated in a primate chair equipped with a response lever. It takes practice to learn how to live without drugs.
What does relapse expression mean?
... Medical Dictionary; Legal Dictionary; Financial Dictionary. It is important to address any deficits in coping skills, to identify the needs that likely induce drug-seeking, and to develop another way to meet them. For example, multiple sclerosis and malaria often exhibit peaks of activity and sometimes very long periods of dormancy, followed by relapse or recrudescence. Reinstatement of drug use after a period of non-use or abstinence is typically initiated by one or a combination of the three main triggers: stress, re-exposure to the drug or drug-priming, and environmental cues. The term is broadly used across the medical practice. Medical Definition of Relapse Medical Author: William C.

The extinction sessions are continued until the animal ceases the drug-seeking behavior by pressing the lever. , Drug taking and relapse are heavily influenced by a number of factors including the pharmacokinetics, dose, and neurochemistry of the drug itself as well as the drug taker’s environment and drug-related history. , Various medications are used to stabilize an addicted user, reduce the initial drug use, and prevent reinstatement of the drug. , Neuroimaging has contributed to the identification of the neural components involved in drug reinstatement as well as drug-taking determinants such as the pharmokinetics, neurochemistry, and dose of the drug. Receptor recovery can be upregulated by administration of receptor antagonists, while pharmacotherapeutic treatments for neruoadaptations in the medial prefrontal cortex are still relatively ineffective due to lacking knowledge of these adaptations on the molecular and cellular level.  The stimulus may be the drug itself, the visual stimulus that was initially paired with the drug intake, or a stressor such as an acoustic startle or foot shock. In medicine, relapse or recidivism is a recurrence of a past (typically medical) condition. The visual stimulus associated with the drug and completion of the task is also removed.
