Autism and Down syndrome are different health conditions. They have different symptoms, manifestations, treatments, and medication. Autism is a neurobehavioral condition, which includes problems in speech, communication, non-verbal and verbal communication, interacting, social, and motor skill.

Down syndrome is also referred to as trisomy 2. It is a genetic disorder that is caused by the third copy of chromosome 21. Some people live with Down syndrome and autism all their lives. Down syndrome is a result of a delay in growth, poor muscle tone, and a lower IQ.

Autism’s effects include weakened social cognitive and interaction, the restricted focus of interests and sensitive power of sensation; some people also suffer a delay in cognitive development, while the effect of the down syndrome includes upward slant eyes, delay in physical growth, delayed speech, learning disability, delayed crawling and walking, short stature and others. There are 3 types of Autism which are Autistic disorder, Pervasive developmental disorder, Asperger syndrome.

Autism is a pervasive neurological disorder that is noticeable in early childhood and extends throughout the lifespan, characterized by language development, atypical communication, eye contact, and sensory experiences. This lifelong developmental condition is also known as an autism spectrum disorder.

While some researches affirmed that genetic factor is one of the causes of autism, there are, however, other causes of this condition that are yet to be identified. Down syndrome, on the other hand, is a medical condition that makes a patient share a certain resemblance to the Mongoloid race. According to researches, down syndrome is caused by a chromosomal excess, which in turn causes a delay in the cognitive function and ability of the patient, certain characteristic facial features, small stature, etc.

The common types of autism are Asperger Syndrome, classic autism, atypical autism. The common types of down syndrome are Mosaic Down syndrome, Trisomy 21, Robertsonian translocation. While there's no known cause of autism, down syndrome is caused by a chromosomal excess, usually a product of abnormal cell division.

Down Syndrome and Autism are two types of medical conditions. Some people mistake them for one another, but they are two different conditions. One of the differences between them is the cause of the condition.

Trisomy 21 is the cause of Down Syndrome. A person should only have two copies of chromosome 21. When it comes to Trisomy 21, it means that chromosome 21 has three copies of it. Compared to down syndrome, autism does not have a cause.

Research is being done to try to find the cause, but so far there is not one known. Autism is growing in diagnosis because more people are aware of the condition.

One of the biggest mistakes of people is assuming that Down Syndrome and Autism are the same. These are two different types of conditions that may affect people from all over the world. Down Syndrome is usually caused by Trisomy 21, which means there are three copies of chromosome 21 as compared to the usual two copies that people may have. Some people who have down syndrome are also diagnosed with autism.

Autism, on the other hand, has no known cause yet. There are some studies and researches about it, but there are not enough details that will prove if there are actual causes of getting this condition. There are some people who are saying that more and more people are being diagnosed with autism, probably because people are more aware of it now as compared to before.
