Dopamine necklace V | gold vermeil
Dopamine dysregulation underlies two of the most prevalent neuropsychiatric conditions — schizophrenia and ADHD — through opposite mechanisms. Schizophrenia involves excess subcortical dopamine; ADHD involves insufficient prefrontal dopamine. Both conditions respond to dopamine-targeted pharmacology, which is how we know the dopamine hypothesis of each has substance.
The Science Behind Dopamine
The dopamine hypothesis of schizophrenia — proposed in the 1960s and refined since — holds that excess dopamine D2 receptor activation in the striatum underlies the positive symptoms (hallucinations, delusions) of schizophrenia. All effective antipsychotics block D2 receptors; dopamine-releasing drugs can induce psychosis in healthy individuals. The updated version adds that hypodopaminergia in the prefrontal cortex underlies the negative and cognitive symptoms. ADHD involves the opposite prefrontal situation: insufficient dopamine (and noradrenaline) tone in PFC networks, impairing signal-to-noise in working memory circuits. Methylphenidate and amphetamines raise dopamine at the synapse and improve prefrontal function. Two disorders, same neurotransmitter, different brain regions, opposite directions.

FAQ
Q: Who understands the schizophrenia-ADHD paradox?
A: Neuroscientists studying dopamine's dose-response relationship. Schizophrenia involves excess subcortical dopamine; ADHD involves insufficient prefrontal dopamine. Same molecule, opposite problems, solved by dopamine-targeted drugs.
Q: What does that dopamine dysregulation tell us?
A: It tells us dopamine's effects are exquisitely tuned to brain region and circuitry. There's no universal 'dopamine level' - there's only the right level in the right place at the right time.
Q: What's the specification?
A: Vertical dopamine in 18K gold vermeil on a 45 cm gold vermeil chain.
Q: What's the DHL timeline?
A: DHL Express, 5 business days worldwide.
