Although most affected individuals present with intractable neonatal seizures that are unresponsive to anticonvulsants, some individuals present with later onset of seizures in infancy or early childhood ( 3).[epilepsygenetics.net]
They also present with no abnormal findings during any form of examination and there is no evidence of a presumptive trigger for the spasms.[news-medical.net]

Key words : Pyridoxine dependent seizures; Neonatalseizures Pyridoxine-dependent epilepsy is a syndrome that usually presents with neonatal intractable seizures. It may present in later infancy or early childhood.[indianpediatrics.net]
Symptoms can include peripheralneuropathy, a pellagra-like syndrome, anemia, and seizures, which, particularly in infants, may not resolve when treated with anticonvulsants.[merckmanuals.com]
Detailed evaluation revealed that psychological symptoms were of alcohol-dependent syndrome and neurological symptoms were due to alcoholic peripheralneuropathy.[ijnpnd.com]

In their study, severe acute pyridoxine deficiency in young ducklings was also characterized by severe anemia while chronic pyridoxine deficiency in older ducklings produced paralysis, convulsions, severe microcyticanemia, and poor feather development[medical-dictionary.thefreedictionary.com]
While this may be correct in some cases, P5P deficiency can also cause microcyticanemia.[metabolichealing.com]
Vitamin B 6 deficiency may impair hemoglobin synthesis and lead to microcyticanemia (3). Deficiency in another B vitamin, niacin, is easily prevented by adequate dietary intakes.[lpi.oregonstate.edu]

Shorter duration between the onset of IS and initiation of standard treatment appears to lead to an improved outcome; therefore early recognition of the seizures and early treatment are essential.[childneurologyfoundation.org]
According to the researchers, these results “suggest that early diagnosis and treatment with this new triple therapy may ameliorate the cognitive impairment in PDE”.[epilepsyresearch.org.uk]
In general there is not much difference between treatment with ACTH and vigabatrin in terms of control, outcome and severe side-effects. Second-line treatment This includes: Benzodiazepines, valproate, lamotrigine, topiramate or zonisamide.[patient.info]
Prognosis The prognosis for children with IS is largely dependent on the underlying cause. The intellectual prognosis for children with IS is generally poor because many babies with IS have neurological impairment prior to the onset of spasms.[childneurologyfoundation.org]
The prognosis for idiopathic infantile spasms tends to be better than for symptomatic infantile spasms [ 10 ].[patient.info]
