Is your little one a little hesitant to join in and play with other children? Or have you ever felt like he has a hard time putting his feelings into words? Sometimes, as a mother or father, when you see little things like this, it's normal for you to feel a little scared and suspicious. That's what we're going to talk about today.
What is Pervasive Developmental Disorder (PDD)?
Simply put, Pervasive Developmental Disorder , often abbreviated as ``PDD'', is a term used in the past to describe several developmental delays that affect a child's ability to socialize, communicate, and communicate with others.
But, it's good to know. Doctors now call this condition Autism Spectrum Disorder , or ASD for short. The name changed in 2013. The American Psychiatric Association (American Psychiatric Association) brought four previously separate conditions under one umbrella in their diagnostic manual, the DSM-5. The four conditions are:
- Autistic disorder
- Asperger's syndrome
- Childhood disintegrative disorder
- Pervasive developmental disorder not otherwise specified (PDD-NOS)
So, you can see that `(PDD)` is now part of the broader category `(ASD)`. However, throughout this article, we will use both `(PDD)` and `(ASD)` to make it easier for you to understand.
Children with this ``(PDD)`` may face various challenges. For example:
- Being late in starting to speak, or having difficulty expressing ideas.
- If there is a small change in their daily routine, whether it's in their routine or in the environment they live in, it can be difficult for them to adjust to it. Imagine, if you take them to school on a different route than they usually take, they might get upset.
- Difficulty connecting with others and understanding their feelings.
How common is this PDD condition?
In fact, PDD is one of the most common disorders in the ASD category. Only 47% of those diagnosed with ASD are said to fall into this category.
What are the symptoms of PDD?
The main symptoms of children with PDD are difficulty communicating and socializing with others . They may also experience the following:
- Doing the same thing over and over again: Things like waving your arms, rocking your body back and forth, or playing with the same toy in the same way.
- Difficulty expressing ideas through language: Some children have difficulty forming words, while others take a long time to start speaking.
- It can be difficult to adjust to changes in daily habits: As mentioned above, even small changes can have a big impact on them.
- Avoiding eye contact: Looking away or not making eye contact when talking.
- Difficulty engaging in conversation: Being slow to respond when someone asks a question, or having difficulty starting or continuing a conversation.
- Difficulty controlling one's emotions: easily angered, or feeling sad or anxious.
- Changing tone of voice: Sometimes speaking in the same tone (`flat voice`), or speaking in a very high voice.
The important thing is that not all children with PDD are the same. Some children may have very mild symptoms, while others may be more severely affected. Most people fall somewhere in between.
What are the causes of PDD?
To be honest, researchers haven't yet found a single cause for PDD. But they believe that it is caused by a combination of factors. The main ones are:
- Genetics: Many experts believe that genes play a role in the development of PDD. But they are still trying to figure out exactly how. Many people with PDD have certain changes in their genes, called gene mutations . In fact, scientists have identified more than 100 genes on different chromosomes that are linked to ASD in some way. But it is very complex. Not everyone with PDD has the same mutations in all of their genes. Also, some of these mutations can be found in people who do not have PDD. Most researchers now agree that certain genetic mutations can cause certain symptoms or control how severe those symptoms are. At the very least, these mutations may increase the risk of developing PDD.
- Environmental factors: Suppose you have a genetic predisposition to develop PDD. Then, exposure to certain environmental factors can increase this risk. For example, if you have a certain genetic mutation, have an infection, or are exposed to a toxin, you are more likely to develop PDD.
- Biology: Researchers are still looking into biological factors that may increase the risk of PDD. These may include conditions that affect your metabolism, immune system, or certain parts of the brain.
What are the risk factors for PDD?
A risk factor is something that increases the likelihood of developing a disease. Experts have identified several such risk factors for PDD:
- Having a brother or sister with PDD or another type of ASD.
- Some genetic conditions, such as fragile X syndrome or Down syndrome .
- The age of the parents at the time of the child's birth is over 35 years (especially the mother's age - `advanced maternal age`).
- Being born with a very low birth weight.
What are the possible complications of PDD?
Although everyone with PDD has their own unique challenges, the severity of symptoms can vary greatly. Some children with PDD can communicate normally, while others may not speak a word. Your doctor can help you determine what kind of help your child needs. Early diagnosis and treatment can often help reduce your child's symptoms.
How do doctors diagnose PDD?
There is no specific lab test or medical exam that can diagnose PDD. Instead, doctors observe a person's behavior and look at their developmental history.
The American Academy of Pediatrics recommends that all children be screened for ASD between 18 and 24 months of age. Many doctors do this screening during their regular developmental and wellness checkups. During this time, your doctor will talk and play with your child. They will also ask you questions about how your child behaves, talks, and moves around at home.
Although these diagnoses are often made in childhood, doctors can diagnose PDD and ASD in older children, young people, and adults. If you think you or your child may have PDD or a related condition, talk to your doctor. He or she can test you or refer you to a specialist in ASD.
How is PDD treated?
Doctors use a variety of treatments to manage PDD. The main ones are:
- Supportive therapies
- Medications
- Complementary medicine
Treatment options may vary from person to person. What works for one person may not work for another. Everyone's needs are different. Your doctor will create a personalized treatment plan that will help you or your child get the help they need most.
Supportive therapies
The main treatment for PDD is supportive care. This may include:
- Speech therapy: Helps develop the ability to communicate and understand words.
- Occupational therapy: Helps strengthen body coordination and learn daily tasks, such as bathing, dressing, and brushing teeth.
- Physical therapy: Helps develop motor skills, learn how to exercise, and increase strength.
- Applied behavioral analysis (ABA): This is a behavioral therapy that attempts to increase good behaviors and reduce bad behaviors.
Medications
There are no medications that can directly treat PDD. However, many people with PDD also have other conditions, such as attention-deficit/hyperactivity disorder (ADHD) , anxiety , and depression . In such cases, medications can help improve their overall quality of life.
Complementary medicine
Complementary medicine is the use of non-traditional methods in conjunction with conventional treatments. This can include many things, such as:
- Art therapy
- Music therapy
- Massage
- Acupuncture
- Yoga
- Meditation
Your doctor can help you find complementary therapies that can improve your overall health and well-being.
Can PDD be prevented?
No. There is nothing you can do to prevent PDD or any other condition that falls under the category of ASD. Just because you or your child has it doesn't mean you did anything wrong. There are many reasons why people develop PDD, none of which are under your control. Also, there is no scientific evidence that childhood vaccinations cause PDD or ASD.
The best way to manage PDD is to diagnose the disease early and start interventions early . But it's never too late to start treatment, as treatment can be beneficial at any age.
When should I see my doctor?
If you think your child has PDD or a similar condition, talk to your doctor about developmental screenings. He or she will tell you if your child's screenings are normal and if you need to see a specialist for further testing.
If you are an adult and think you may have a condition called PDD or ASD, ask your family doctor or primary care physician for help. With the increased awareness of ASD, there are more resources and support available today than there were just a few years ago. It is never too late to get the support you need.
Whether it's you or your child, receiving a diagnosis of a developmental disorder can be scary—like stepping into a new world. Or it can be a relief to finally have an answer to a question you've been wondering about for so long. However, your doctor is there for you. Experts know a lot more about ASD today than they did even a decade or two ago.
In summary, things to remember (Take-Home Message)
People with ASD see the world a little differently – but that's not a bad thing. Creating some structure, or order, in your daily life is a great way to support yourself. It's also a great way to show your child that you love them just the way they are.
Don't worry. You are not alone. If you suspect you have PDD or ASD, be sure to seek medical advice. Early intervention can go a long way in improving your child's future. Remember, every child is precious, and we can help every child reach their full potential.
