Autism, or Autism Spectrum Disorder (ASD), presents a wide range of symptoms that can vary in severity. Common social symptoms include difficulty in understanding social cues, maintaining eye contact, forming relationships, and engaging in conversations. Individuals may struggle with recognizing emotions in others, leading to challenges in social interactions. Communication difficulties are also typical, including delayed speech development, limited vocabulary, or reliance on nonverbal communication. Some individuals may repeat phrases or words (echolalia) or use language in an unusual way. Repetitive behaviors are another hallmark, such as hand-flapping, rocking, or adhering to strict routines. Changes in routine can cause distress, and individuals may develop intense, focused interests in specific topics or objects. Sensory sensitivities are common, with individuals overreacting to stimuli like bright lights, loud noises, or certain textures. They may seek sensory input, like spinning or touching objects repetitively. These symptoms can appear in early childhood and may vary in intensity as the person develops.
