Trigoncephaly is a skull deformity that is a direct result of premature fusion of the following

Correct Answer: D

Rationale: Trigonocephaly results from premature fusion of the metopic suture , which runs midline on the forehead, causing a triangular skull shape with a pointed forehead. Sagittal suture fusion leads to scaphocephaly (long, narrow skull), coronal suture fusion to brachycephaly or plagiocephaly, and lambdoid suture fusion to posterior plagiocephaly. Multiple suture fusion causcomplex craniosynostosis, not specifically trigonocephaly. The metopic suturunique frontal location directly correlatwith trigonocephalys characteristic ridge and shape, making D the correct answer.

Correct Answer: D

Rationale: Hypoxic-ischemic encephalopathy (HIE) is the leading cause of neonatal seizures, occurring in 1-2 per 1,000 live births, due to perinatal asphyxia impairing cerebral oxygenation and triggering seizures. Vascular events like stroke, infections like meningitis, brain malformations , and metabolic disturbanc(e.g., hypoglycemia) are less common, with HIE dominating due to its prevalence in term infants and direct neuronal injury. Studi(e.g., VolpNeurology of the Newborn) confirm HIprominence, making D the correct answer over other etiologies.

Correct Answer: A

Rationale: TSC diagnosis usmajor (e.g., shagreen patch) and minor featur(e.g., dental pits, gingival fibromas). Shagreen patch is a major feature connective tissue nevus not minor, unlike cerebral migration lin, dental pits , gingival fibromas , and bone cysts . This classification (TSC Consensus) distinguishA as the exception and correct answer, as it elevatdiagnostic weight beyond minor status.

Correct Answer: B

Rationale: Spastic quadriplegia is the most seizure-associated CP type, affecting all limbs and often linked to severe brain injury (e.g., HIE), increasing epilepsy risk (~50%). Spastic hemiplegia and diplegia have lower rat(~30% and 20%), while hypotonic and ataxic CP are less epileptogenic. Quadriplegias extensive cortical damage drivits seizure prevalence, making B the correct answer.

Correct Answer: D

Rationale: By 9 months, infants pull to stand , use pincer grasp , play pat-a-cake , and imitate sounds , per developmental mileston(e.g., CDC). Coming when called emergcloser to 12 months, requiring advanced cognition and mobility. This lag response versus action makes D the exception and correct answer.
