Autism and Attention Deficit Hyperactive disorder (ADHD) both are neurodevelopmental disorder which impact the same brain functions. Studies have shown that two-third of the total affected children with ADHD show autism symptoms too. There is a thin line of difference between their characteristic symptoms, lets learn about both in detail.

AUTISM- the isolated self

Autism can be diagnosed in children from the age of 2 years. Each autistic child may show different symptoms. You cannot really categorise them into one.

It is one of the syndrome that falls under the range of autism spectrum disorders. The word Autism is a Greek word ‘ autos’ which means ‘self’.

Here are some of the distinct characteristics to look out for in an autistic child:

  • They find difficulty in communicating with others

  • They prefer to sit alone or play alone. Finds difficult to make friends.

  • Sensory Dysfunction – cannot stand loud noises, strong smell or flavour.

  • Repetitive Behaviour- Doing or saying the same things over and over again. For example, constantly clap hands.

The cause of Autism is largely genetic. So if diagnosed from start and treated well then it effectively reduces the symptoms.

How to treat them?

  • Most diagnosis is by age of 2. Hence, an overall approach therapy- occupational, behavioural, medical, dietary and physical would help them to cope up with environment and other children better.

  • Being over sensitive to, touch , taste and sight they tend to become picky eaters. They prefer to eat only a particular food item over and over again making them nutritional deficit. These deficits needs to be addressed through supplements under the guidance of doctor.

  • Expose them to different varieties of the same food item. For example, if they eat apple jam, then the child will be open to try apple pie or apple as a whole fruit.

  • Usually they are sensitive to foods containing casein ( milk, paneer, curd) , gluten (wheat, barley, oats) or preservatives (packaged food items). Try to eliminate these items one at a time and observe how they respond.

  • Once the sensitivity is known, use the substitutes for it. For example, in case of casein substitute their milk/paneer requirements with soybean milk/ tofu respectively.

  • Gut health is compromised called as leaky (i.e. Gut is permeable to toxins and gets absorbed into the blood stream). Long term studies have shown that bacteria B. Fragilis helps to recover from leaky gut and reduce the autistic syndrome.

Medical therapy is important as the drugs given will not cure autism but reduce anxiety and depression in the child. This will improve their learning and communication skills and make them more friendly and open.


ADHD stands for Attention Deficit Hyperactive Disorder. Its seen in both Children and adults. Usually, difficult to identify at before the age of 5 in children because being inattentive , hyperactive are the normal traits shown by any toddler or kid.

It’s symptoms may or may not stand out clearly depicting ADHD affected child. Symptoms include:

  • Cannot focus on one task for a long time

  • Difficult in paying attention in class or in any given activity or discussion

  • Always needs to move around. Cannot sit at one place.

  • Usually responds or answers back without thinking much/ Impulsive behaviour

Along with behavioural therapy, diet also plays an important role in managing ADHD. Studies have shown that a diet high in sugar containing foods worsens the hyperactive trait in ADHD children. This is because sugars provide instant energy to brain, so they tend to overthink, overreact more.

A well balanced diet including veggies, fruits, complex carbs like high fiber cereals and more of proteins will slowly help to ease the symptoms.
