Breath holding spells (BHS) are common non-epileptic paroxysmal behavioral involuntary episodes occurring in up to 5.9% of healthy children. The attacks occur in early childhood (0.5-3 years) but are self-limited by school age (4-5 years old) (90%). Classically, BHS were classified as cyanotic (blue), pallid (pale) and mixed based on the color change of the child during the spell. In general, cyanotic spells have been classically described in a toddler with excessive temper tantrums \[stubborn, easily frustration or annoyed. The mechanisms of BHS are controversial. The most suggested cause of BHS is instability of the autonomic nervous system, inhibition of respiratory effort and cyanosis in cyanotic BHS and bradycardia or a brief asystole and cerebral hypoperfusion in pallid BHS. Iron deficiency anemia (IDA) has been widely regarded as a risk factor for BHS in nearly 50% of children due to reduced brain oxygenation \[4\]. It is generally agreed that the long-term prognosis is considered good \[1\]. There is no definite therapy for BHS. In children with low frequency spells, parental reassurance are just enough; however, high frequency spells may result in anxiety to the parents or fear from sudden death of the child or development of mental subnormality. Treatment of iron has been reported to result in reduction of the frequency of spells or its stoppage. Some reported improvement of BHS with piracetam \[a nootropic drug known to increase brain oxygenation\]. We did not find systematized published reports evaluating the effectiveness of antiepileptic drugs (AEDs) in reduction of spells frequency of cyanotic BHS or their stoppage.
