The Dopamine / Schizophrenia Connection. The behaviour of people with schizophrenia is frequently extremely odd and appalling. In fact, they cannot tell the difference between reality and the imagined. In other words, they are experiencing psychotic episodes, which are marked by delusions (thoughts that are disconnected, strange and have no foundation in reality) hallucinations (audio, visual, and tactile) and muddled thinking, " connections among their thoughts are extremely loose... jump from one subject to another entirely unrelated topic...they make no rational sense". (Schizophrenia,2003, Para 1) There is a biochemical cause for this affliction; this paper researches schizophrenia's connection to the dopamine systems, and it starts with the oxidization of the catecholamines. The catecholamines (Norepinephrine; Epinephrine; Adrenalin; Dopamine) (Davidson, 1994) enter a process of oxidation (Smythies, John, R, 1997), and as the process advances, the catecholamines transform into o-Quinones: "O-Quinones are physiological oxidation products of catecholamines that contribute to redox cycling, toxicity and apoptosis, i.e. the neurodegener

(Smythies, J, 1998) Dopamine [C8H11NO2], a hormone-like substance, is an important neurotransmitter. Neurotransmitters: Para 1, Retrieved November 22, 2003, from: http://www. (Mann, 1996} The research clearly demonstrates that excessive dopamine production is causally linked to schizophrenia.
