=== Dopamine ===

For example, problems in producing dopamine (mainly in the [[substantia nigra]]) can result in [[Parkinson's disease]], a disorder that affects a person's ability to move as they want to, resulting in stiffness, tremors or shaking, and other symptoms. Some studies suggest that having too little or too much dopamine or problems using dopamine in the thinking and feeling regions of the brain may play a role in disorders like [[schizophrenia]] or [[attention deficit hyperactivity disorder]] (ADHD). Dopamine is also involved in addiction and drug use, as most recreational drugs cause an influx of dopamine in the brain (especially [[opioid]] and [[methamphetamine]]s) that produces a pleasurable feeling, which is why users constantly crave drugs.<ref>{{Cite web |title=Dopamine: What It Is, Function & Symptoms |url=https://my.clevelandclinic.org/health/articles/22581-dopamine |archive-url=http://web.archive.org/web/20250303012437/https://my.clevelandclinic.org/health/articles/22581-dopamine |archive-date=2025-03-03 |access-date=2025-03-07 |website=Cleveland Clinic |language=en}}</ref>
