Dopamine can undergo both oxidation and reduction reactions, playing a crucial role in its physiological functions and influencing various pathological conditions. (thesciencenotes.com)
The role of dopamine agonist treatment in corticotroph pituitary tumors is controversial. (unige.it)
And, for this reason, dopamine plays a huge role in who you are as a person, plus your overall health. (dyln.co)
However, they do believe that dopamine plays a role in the condition. (medicalnewstoday.com)
While the role of dopamine in vulnerability toward nicotine addiction cannot be excluded, the findings suggest that altered dopamine function of smokers is a consequence of nicotine consumption rather than the cause. (psychcentral.com)
Our data show that dopamine may play an important role on seizure severity in the pilo's model acute period, which seems to be due to dopamine inhibitory action on motor expression of seizure. (scielo.br)
The role of dopamine signaling in epileptogenesis. (scielo.br)
The results also have some theoretical and practical implications in clarifying the interaction between cognition and affect , and the role of positive affect in improving cognitive functioning and problem solving skills in social relations. (icssjournal.ir)
Changes in dopamine signaling appear to play an important role in both ADHD and ASD. (medlineplus.gov)

Dopamine is more potent at the D4 receptor with 2 allelic repeat or 7 allelic repeats than the variant with 4 allelic repeats. (wikipedia.org)

Articles and documentaries describe dopamine as what makes life worth living, the chemical that permits every enjoyable moment to be savored, the "hit" everyone is chasing whether through social media, psychoactive substances, sports, food, sex or status. (scientificamerican.com)
Those blunted dopamine receptor variants are associated with substantially increased risk of addiction to a range of substances and behaviors. (artdiamondblog.com)

In some cases, however, serotonin may inhibit dopamine production, which means that low levels of serotonin can lead to an overproduction of dopamine. (medicalnewstoday.com)
Having abnormal levels of either dopamine or serotonin can lead to several different medical conditions. (medicalnewstoday.com)

Our results showed that participants with the 9-repeat genotype, which is known to be associated with less DAT expression and higher levels of dopamine, exhibited better performance in the learning phase than participants who were 10/10 homozygotes (higher DAT and less dopamine). (alquds.edu)
Crucially, genetic variants that suppress dopamine signaling in the pleasure circuit substantially increase pleasure- and novelty-seeking behaviors - their bearers must seek high levels of stimulation to reach the same level of pleasure that others can achieve with more moderate indulgence. (artdiamondblog.com)
Since the hippocampus is one of main structures in the development of this experimental model of epilepsy, the dopamine levels in this region were also determined after drug administration. (scielo.br)
