At what age is the onset of West syndrome most commonly observed?

• A. 12 years
• B. 5 years
• C. 4 months
• D. 18 years

Answer: (C)

West syndrome, also known as infantile spasm syndrome, typically presents during the first year of life, with the most common onset occurring around 4 to 8 months of age. Therefore, the selection of 4 months is aligned with this age range, as it is within the period when the first symptoms are most likely to be observed. Understanding the typical onset age for West syndrome is crucial since early identification plays a significant role in effective management and treatment. Infants experiencing symptoms like developmental regression, unusual posturing, and clusters of spasms should be evaluated promptly for conditions associated with this syndrome, which significantly impacts their neurological development.
