“…Roy et al (1991a) found lower CSF levels of the dopamine metabolite HVA in depressed compared with never depressed subjects with alcohol dependence. Although multiple studies have shown changes in CSF monoamine metabolites in subjects with alcoholism (Roos and Silfverskiöld, 1973;Kato et al, 1979;Goldman et al, 1992;Takahashi et al, 1974;Major et al, 1977;Fujimoto et al, 1983;Virkkunen et al, 1996;Fils-Aime et al, 1996;Petrakis et al, 1999;Adinoff et al, 1996Adinoff et al, , 1995Adinoff et al, , 1991Geracioti et al, 1994Geracioti et al, , 1993Virkkunen et al, 1994;Kaakkola et al, 1993;Roy et al, 1990;Roy and Linnoila, 1989;Hawley et al, 1988;Borg et al, 1982;Geracioti, 1997), the study by Roy et al (1991a), to our knowledge, is the only study that measured CSF HVA in depressed individuals with alcoholism. Most studies do not distinguish possible biological effects of related psychopathology such as depression, psychosis, suicidal behavior, or smoking.…”
