Autism Signs: Keep in Mind
The symptoms of ASD can manifest at any age, despite being a lifelong disorder that starts in early childhood. The fact of it is that some people simply will not manifest any symptoms until later in life, or until after particularly stressful or traumatic life experiences.
Appearance-wise, there is really nothing that will set individuals with ASD apart from others who do not have the condition. The only differences are behavioral – and these symptoms can range from very mild to very severe.
