Yes, autism can be diagnosed before the age of 2, and it is also a lifelong condition. Early signs of Autism Spectrum Disorder (ASD) often appear between 12 and 24 months of age. These may include limited eye contact, delayed speech, lack of response to name, or repetitive behaviors. While every child develops differently, early developmental screening is key when concerns arise.



Pediatricians and specialists can reliably diagnose autism as early as 18 months using observation, standardized tools, and developmental checklists. The earlier the diagnosis, the sooner intervention like ABA therapy can begin, greatly improving long-term outcomes.

Autism is a lifelong neurodevelopmental disorder, meaning the core traits of ASD typically persist into adulthood. However, individuals can gain significant skills and independence with the right support. Symptoms and support needs may evolve, especially with personalized care.
