Therefore gathering data turns out to be difficult task.
But most doctors by and large use the following behavioural abnormalities as yardsticks.
- Unusual eye contact
- Failure to perform the tasks such as running when called by name
- Inability to articulate through gesture
- Unable to involve in interactive play
- Unable to interact with peers
Some of the symptoms may be apparent by third month or some may be latent.
