Autism spectrum disorder (ASD) is a condition that affects how people see the world and interact with others.
People with ASD might find it hard to understand social rules, have conversations, or make friends. They may also be deeply passionate about certain topics (ie special interests) or repeat behaviours to regulate their emotions, which is known as stimming.
Everyone with ASD is different. Some people might need a lot of help in their daily lives, while others can do most things independently. Autism is called a ‘spectrum’ because there are many types of autism, from mild to more noticeable.
Similarly, people with autism can also have different levels of social and emotional intelligence.
For example, research shows that autistic girls have higher social cognition and emotional intelligence compared to autistic boys. The sex differences may be apparent due to gender roles and expectations.
It is important to find out if someone has ASD early so they can get the right help. Psychologists in Singapore may offer support that includes learning different ways to communicate, understanding how to act in social situations, and managing emotions.
In this article, we will look into the symptoms and causes of autism spectrum disorder.

Autism spectrum disorder (ASD) does not have a single primary cause. The condition usually arises due to a combination of genetic and environmental factors.
If a family member has autism, the chances of another family member (eg children) having autism increases.
A genetic component has a major role in developing autism. However, this does not mean that someone may have autism by default due to genetics.
Moreover, genes may affect brain development, especially in the way brain cells communicate. Brain development plays a primary role in the severity of symptoms.
The environment also contributes to the development of ASD.
Exposure to certain substances during pregnancy, such as heavy metals, environmental toxins, and specific medications like valproic acid or thalidomide, has been associated with an increased risk of ASD.
Online psychologists in Singapore can provide the right support to improve the quality of life and functioning of autistic people.
Based on the manifestations and severity of the symptoms, different types of psychotherapy can help.
Some of these include:
Moreover, self-care methods such as massages, weighted clothing and meditation can also help in:
