These transcription factors have been shown to play a role in the short-term and long-term adaptive changes in the brain. CREB has been implicated in learning, memory, and depression and enriched in cocaine users within the nucleus accumbens. CREB seems to upregulate many genes in its pathway within the reward regions of the brain.
The goal of addiction research is to find ways to prevent and reverse the effects of addiction on the brain. Theoretically, if the structural changes in the brain associated with addiction can be blocked, then the negative behaviors associated with the disease should never develop.
Cocaine dependence is a neurological disorder that is characterized by withdrawal symptoms upon cessation from cocaine use. [1] It also often coincides with cocaine addiction which is a biopsychosocial disorder characterized by persistent use of cocaine and/or crack despite substantial harm and adverse consequences.
ΔFosB is the most significant biomolecular mechanism in addiction because the overexpression of ΔFosB in the D1-type medium spiny neurons in the nucleus accumbens is necessary and sufficient for many of the neural adaptations and behavioral effects (e.g., expression-dependent increases in drug self-administration and reward sensitization ...
Cocaine (from French cocaïne, from Spanish coca, ultimately from Quechua kúka) [13] is a tropane alkaloid that acts as a central nervous system stimulant.As an extract, it is mainly used recreationally and often illegally for its euphoric and rewarding effects.
Addiction is a progressive psychiatric disorder that is defined by the American Society of Addiction Medicine as "a primary, chronic disease of brain reward, motivation, memory and related circuitry." It is characterized by the inability to control behavior, it creates a dysfunctional emotional response, and it affects the users ability to ...
[3] [4] [5] Methamphetamine psychosis, or long-term effects of stimulant use in the brain (at the molecular level), depend upon genetics and may persist for months or years. [6] Psychosis may also result from withdrawal from stimulants, particularly when psychotic symptoms were present during use.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption ...
