We examined the role of serotonin in inherited, acquired and idiopathic dystonia.
Most studies point towards a hypofunction of the serotonergic system in dystonia.
Serotonergic/dopaminergic imbalances may be an important modulator of dystonia.
High prevalences of psychiatric co-morbidity may suggest serotonergic dysfunction.
Influencing serotonin may form a new potential target for therapeutical interventions.
