There is no way to predict how long your child will keep his special interest. Some children will change interests over time, passionately pursuing one topic only to later drop it and replace it with another. However, in general it seems that the special interests of Asperger’s Disorder children persist for years. Their area of focus usually matures as they grow, but the topic may remain the same.
Children interested in anime comic books will collect them for years; later they trade them, become interested in reading the collector magazines, start to keep track of the monetary value of each comic book, and later engage in selling and buying comic books to increase the value of their collection. Such a special interest can hold their fascination from elementary through high school years. It is not unusual for a special interest to turn into a career.
College or trade school in graphic arts or animation may be the outcome of a childhood interest in comic books. An interest in insects may lead to a degree in biology and career as an entomologist. A child who collects locks may become a locksmith. While not all special interests lead to careers, they do provide a great source of pleasure that many non-Asperger’s Disorder individuals never experience.
