“…In addition, cocaine-induced ataxia and PCs degeneration have been suggested as a consequence of the early-life modification to the cerebellar serotonergic system (Arpin-Bott et al, 2006; Summavielle et al, 2004). There is also growing evidence that early selective 5-HT reuptake inhibition may induce motor deficits later in life in both humans (Albertini et al, 2004; Casper et al, 2003) and rodents (Bairy et al, 2007; Lisboa et al, 2007; Maciag et al, 2006). Moreover, clinical studies demonstrate improved cerebellar ataxia in response to treatment with 5-HT precursor (Trouillas et al, 1988; Trouillas et al, 1995) as well as 5-HT1a agonist (Lou et al, 1995; Trouillas et al, 1997).…”
