Histopathological ence in its entirety for all purposes. evidence of cerebral hemorrhage and hypoxia has been detected in some severely affected foals (Palmer and Ross FIELD dale (1976), supra). However, many foals do not have histo The present invention relates to methods of diagnosing and 15 logical evidence of hypoxia, edema or hemorrhage (Bernard, treating syndromes of reversion to fetal consciousness in a et al., In: Proceedings, 41st American Association of Equine neOnate. Practitioners, Lexington, Ky. pp. 222-224). Furthermore, many foals have a normal birth and recover quickly and fully BACKGROUND from the condition. This is in contrast to infants and newborn rats with asphyxia in which a significantly longer recovery Neonatal maladjustment syndrome (NMS) is a common time is needed and long-term neurological deficits are often disorder of neonatal foals that manifests within the first 72h manifest (Kiss, et al., (2009) Brian Res 1255, 42-50; van of life (Bernard, et al (1995) In: Proceedings, 41st American Handel, et al., (2007) Eur J Pediatr 166, 645-654).

The proposed mechanisms include hypoxic and Suggest that the syndrome may not be exclusively the result of ischaemic events prior to, during and shortly after parturition hypoxia. (Palmer and Rossdale, (1976) Res Vet Sci 20, 267-275). Neonatal foals have high concentrations of pregnanes at Affected foals exhibit neurological dysfunction such as sei birth which decrease rapidly over the first 48 hours of life Zures and altered States of consciousness, behaviour and 30 (Houghton, et al., (1991) J Reprod Fertill 44, 609-617). response to stimuli (Bernard et al. 1995, supra; Ringger, et al.
