In the psychogenic variant of FAS, there may be an underlying psychological or psychiatric disorder such as psychosis, conversion disorder, bipolar disorder, or schizophrenia with ongoing episodes but without identifiable organic brain lesion deficits in the areas connected with language production and speech articulation, suggesting that various other factors and lesions are implicated [2–6, 9, 24–27]. The gene discussed is FAS; the disease is bipolar disorder.
