Simple blue breath holding attacks : consist of a positive Valsava manoeuvre ,
cyanosis , stiffening , and coma .They may be seen usually after the age of six
months and are provoked by frustration or other upset . White reflex asystolic
attacks : consist of vagal asystole , pallor , rapid coma , stiffening and
opisthotonos . They may start earlier and usually follow minor injury . Faints
while standing or sitting are usually well recognised . All three conditions may
be accompanied by late true epileptic phenomena or jerking secondary to cerebral
hypoxia or ischaemia , but their natural history remains self-limiting and
harmless like that of the first episode .
