Boys are more likely to be diagnosed with autism them girls because girls are better at masking the symptoms. It is a common misconception that boys are more likely to have autism but the simple fact is the girls are more likely to fly under the radar. The differences in socialization and grooming in girls is part of the reason why people don’t notice and women are often misdiagnosed with other comorbid conditions such as depression, anxiety, bipolar disorder, PTSD, or other issues.
