During what age does Rett Syndrome typically begin to show regression in development?

• A. After the first year of life
• B. At 6 months of age
• C. At 2 years of age
• D. At 3 years of age

Answer: (B)

Rett Syndrome typically begins to show regression in development after the first year of life, often between 6 to 18 months of age. Although some developmental milestones may have been attained in this early period, children who are affected by Rett Syndrome will start to demonstrate loss of previously acquired skills and developmental regression around this time. This regression includes difficulties in communicating, motor skills, and social engagement, which can be quite noticeable once they reach the point of developmental plateau. The timing associated with the progression of Rett Syndrome differs from typical developmental patterns, which is why recognizing the exact age, often around 6 months, is critical in understanding early signs and symptoms. The development of symptoms and age at regression can vary among individuals, but the onset of regression tends to align more closely with the first year rather than being specific to the ages mentioned in other choices such as 2 years or 3 years, which are generally too late for the initial regression to become apparent.
