Autism in adults is often overlooked, particularly in women, due to societal expectations, masking behaviors, and diagnostic criteria primarily developed for young boys. Many adults with autism, especially those undiagnosed, experience a lifelong sense of “differentness,” struggle with interpreting social cues, and face challenges in relationships and communication. Sensory sensitivities, a need for routine, and a preference for solitude are also common traits, along with intense, focused interests that shape their world. While these signs can be subtle, understanding autism’s diverse presentation and exploring resources can help individuals recognize their neurodivergence, leading to self-validation and a deeper understanding of their unique strengths and challenges. Engaging with supportive communities and seeking professional guidance are vital steps in navigating life as an undiagnosed autistic adult.
