Autism actually now we tell it as autism spectrum disorders that is ASD. It is kind of very devastating thing for a parent to have because this could be a lifelong problem but the early detections, early management definitely helps for it. What it is? Autism is actually a developmental disorder in which the baby usually from the toddler age itself after one year or one and half year you'll see that there is some amount of deviation from the normal development, normal behavior, normal emotional quotient. All these things are seen in a baby with the autism. Is it a genetic disorder? Yes it has certain genetic connections. There are some genetic mutations which happen but most of the time cause is unknown. In the same family there are many children only one child could be autistic but there is a risk of second child also becoming autistic. So it has plus minus genetic relations happening but what does the child affected with? Usually in the autistic child the development one is obviously the milestones get delayed or the milestones which they already had attained during their first year of life will become you know diminishing, they start vanishing, the child who started to speak something like Amma or Appa has certainly stopped or a child who started to stand up with the support or something suddenly stop standing up and sits and starts worsening, regression of milestones what we say that can happen or they may never get those milestones at all. It is not only about the development they are also emotionally having lot of other things. They suddenly become too sensitive for small things and they don't show any sensitivity for some things like if the mother has got some fire on their fingers and she suddenly reacts that baby has no reaction if it's like having that autistic spectrum disorder. They also have other things mainly the social problems like they can't interact, they don't make the eye contacts and they will try to be away from the people the gathering they get very irritated or suddenly they become show sudden reactions when lot of people come unknown people come and sometimes when the people are of their age the toddlers are there they will not be able to communicate with them they will have some adjustment problems or they don't just communicate with them and they don't take turns like we see in kids when they play they do one thing and the next person will wait for the turn they don't wait for the turn they don't know that they need to wait for the turn. So such social you know interaction, social communications that also will be difficult for them. Also they will have certain repetitive behaviors either finger movements or you know twitching of the mouth or sometimes they'll be doing the same work again and again and again and again same cubes they're putting removing but if you restrict from there they get very violent with that sudden violent behavior. So many things are there actually it's a big chapter Autism is a big chapter. So in general they behave they have emotionally different they have socially little different disconnections they are developmentally delay, their speech may delay all these things and usually as the this question states like it's neonate there's nothing like autism in a neonate. You can't figure out autism in the neonate. This usually to the maximum you may be able to figure out before one year nine months to you know one year but definitely we can figure it out before 18 months. Ideal time is at least by one year to 15 months. So that time you can figure it out. 18 months definitely you should figure it out so that you can do early interventions. The later it is you know diagnosed or later it is figured out the later the interventions the damage done is more and how do you diagnose it? How do you diagnose? It it's not like some blood test you can do and diagnose Autism. It's not so easy and many of the times the busy OPD practices doctors have no time or they don't have sensitivity enough to ask questions but we should at least ask the questions basic questions like whether a baby has attained the milestones, how is the social interactions, how is the emotional reactions. Most of the times parents themselves come up with the problems but that may take three years four years sometimes after they go to school or something. So when they are in that six months to one and a half year window period itself some checklists are there.
