Autism affects social communication and behaviour. Signs often appear before age 2–3.

Early assessment and therapy improve communication and independence.

Key concepts

  • Autism is a spectrum — every child is different
  • It is not caused by vaccines or parenting
  • Early intervention matters more than a label

Symptoms and signs

  • Not responding to name by about 12 months
  • Little pointing, showing or eye contact
  • Repetitive movements, lining up toys, strong reactions to sounds

Causes

  • Genetic and early brain development factors
  • Not caused by screen time alone or by vaccines
  • Higher rates in siblings of autistic children

Risk factors

  • Sibling with autism
  • Premature birth
  • Older parental age

Evidence-based management

  • Hearing test and developmental assessment
  • Speech, occupational and behavioural therapy
  • Parent-led communication strategies at home
  • Medicines only for specific problems such as severe irritability or sleep

When to seek professional help

  • Loss of words or social skills at any age — urgent assessment
  • No words by 16–18 months
  • Parents can book a consultation first to discuss concerns before involving the child

Frequently asked questions

Can autism be cured?

Autism is lifelong, but therapy helps children communicate, learn and live more independently.

Is too much mobile the cause?

Screens do not cause autism, but limiting screens and increasing interaction helps all young children.
