The specific influence of genetic and perinatal factors, as well as the impact of early and individualized therapy, remains unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed 41 infants diagnosed with West syndrome at a tertiary center between January 2022 and January 2024. Detailed etiological assessment included neuroimaging, metabolic, and genetic analyses. Patients were classified as symptomatic or cryptogenic. Clinical, radiological, and developmental data, along with treatment regimens and 3\u2010month outcomes, were analyzed. Treatment response was categorized as seizure freedom, &gt;50% reduction, or poor response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Symptomatic etiology was identified in 78% of patients, with genetic mutations (36.6%; including DEPDC5, TUBA1A) and hypoxic\u2013ischemic encephalopathy (HIE) (17.1%) most prevalent. Cryptogenic cases comprised 22%. After 3 months, 24.4% achieved seizure freedom, significantly more common in cryptogenic than symptomatic patients (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006).

Severe developmental delay and radiological abnormalities\u2014especially cortical atrophy\u2014were predominant among patients with genetic and perinatal etiologies and correlated with poorer seizure outcomes (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
