Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Global developmental delay
Significant delays in reaching developmental milestones such as sitting, walking, and talking compared to typical children.
Seek immediate evaluation if your child shows no progress in motor skills or appears to be losing previously acquired skills.
Seizures
Recurrent seizure activity due to abnormal electrical activity in the brain, varying in type and severity.
Seek emergency medical care for any seizure lasting more than 5 minutes or if seizures occur in clusters.
Congenital heart defects
Structural heart abnormalities present at birth, which may include septal defects or other cardiac malformations.
Seek immediate cardiology evaluation if symptoms include difficulty feeding, rapid breathing, or bluish skin discoloration.
Speech and language delay
(neurologic)Delayed onset of speech and language skills, often with difficulty forming words and sentences.
Frequency: 75-85% of patients
Hypotonia
(neurologic)Low muscle tone resulting in floppy limbs and difficulty with motor activities such as sitting upright and crawling.
Frequency: 60-70% of patients
Intellectual disability
(neurologic)Varying degrees of intellectual impairment affecting learning, problem-solving, and adaptive functioning.
Frequency: 50-65% of patients
Distinctive facial features
(constitutional)Subtle facial characteristics such as broad forehead, deep-set eyes, or unusual ear shape that may be noticed at birth.
Frequency: 50-60% of patients
Growth retardation
(constitutional)Poor growth in height and weight, often noticeable in infancy and continuing through childhood.
Frequency: 40-50% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Developmental and Growth Surveillance
Comprehensive regular assessments track developmental milestones, growth parameters, and emerging concerns across all domains. Early identification of delays enables timely intervention services.
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Neurodevelopmental and Behavioral Intervention
Specialized behavioral approaches address autism spectrum features, attention difficulties, and behavioral challenges common in this condition. Individualized support plans promote adaptive functioning.
Additional treatment options
Occupational Therapy Services
Therapeutic interventions address sensory processing differences, fine motor skill development, and daily living skill acquisition. Environmental modifications support functional independence.
complementaryAssociated Symptom Pharmacological Management
Medication addresses specific symptoms such as attention deficit, mood instability, or sleep disturbances that impact daily functioning. Requires careful monitoring for effectiveness and side effects.
medicationNutritional Support and Feeding Management
Assessment and management of feeding difficulties, nutritional adequacy, and growth concerns. Some patients benefit from modified food textures or supplemental nutrition.
dietaryWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
