Hallmarks of autism spectrum disorder and ADHD often overlap. Many autistic children also have symptoms of ADHD — difficulty settling down, social awkwardness, only focusing only on things of interest to them, and impulsivity.
Autism is very distinct from ADHD, but the core symptoms of ADHD-Combined type, i.e., attention deficit, impulsivity, and hyperactivity, would appear to also be features of autism. ASD and ADHD are neurobiological disorders characterized by similar underlying neuropsychological “deficits”.
Can a person be diagnosed with both ADHD and ASD? More than half of all individuals who have been diagnosed with ASD also have signs of ADHD. In fact, ADHD is the most common coexisting condition in children with ASD.
Children with ADHD often have difficulty paying attention to the same thing for too long, and they may get distracted easily. Autistic children may have a limited scope of interest. They may seem to obsess over things that they enjoy and have difficulty focusing on things that they have no interest in.
While ADHD can make it difficult to focus, sit still, or control impulses, autism can limit a person's scope of interests or affect social skills and learning abilities. ADHD and autism often share symptoms, like difficulty communicating or concentrating. Additionally, it's possible that the conditions are connected.
ADHD stimming is when a person with ADHD displays self-stimulatory behavior by repeating certain sounds and movements unconsciously. There are many different examples, including lip biting, rocking back and forth, humming, teeth grinding, or chewing gum.
According to the scientific literature, 50 to 70% of individuals with autism spectrum disorder (ASD) also present with comorbid attention deficit hyperactivity disorder (ADHD). From a clinical perspective, this high rate of comorbidity is intriguing. What is the real significance of this dual diagnosis?
Stimulants don't change the core characteristics of autism.
But some evidence suggests that stimulants can help autistic children with ADHD pay attention and behave less impulsively. In turn, this can help them at school and in social situations. Stimulants can have side effects.
Someone who is considered a savant may be especially skilled in art, math, music, memory recall, or another subject. Savant syndrome is commonly associated with autism but can occur alongside other conditions.
Signs of autism in young children include: not responding to their name. avoiding eye contact. not smiling when you smile at them.
Main signs of autism
Common signs of autism in adults include: finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own.
Although the exact cause of autism is still unknown, there is evidence to suggest that genetics play a significant role. Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Symptoms of High-Functioning Autism
They don't make much eye contact or small talk. People on the spectrum who are high-functioning can also be very devoted to routine and order. They might have repetitive and restrictive habits that seem odd to others. There's a wide range of how they do with school and work.
It is a spectrum disorder, meaning there is a broad variation in the types and severity of symptoms. No two people with ASD have the same symptoms. Borderline autism is not an official term or diagnosis. Instead, it is an informal term referring to less severe ASD symptoms.
Although 2019 research suggests some symptoms of ADHD and ASD overlap, there are distinct differences. A person with ADHD may have attention, hyperactivity, and impulsivity challenges. But an autistic individual may have difficulties with communication, social interaction, and restricted or repetitive behaviors.
Some developmental health professionals refer to PDD-NOS as “subthreshold autism." In other words, it's the diagnosis they use for someone who has some but not all characteristics of autism or who has relatively mild symptoms.
Attention deficit hyperactivity disorder (ADHD) and autism can look a lot like each other. Children with either condition can have problems focusing. They can be impulsive or have a hard time communicating. They may have trouble with schoolwork and with relationships.
Problems with emotional dysregulation, in particular with anger reactivity, are very common in people with ADHD. You are not alone in struggling in this area. Anger may indicate an associated mood problem but often is just part of the ADHD. Either way, changes in traditional ADHD treatment can be very helpful.
Adults with ADHD rarely fall asleep easily, sleep soundly through the night, and then wake up feeling refreshed. More often, ADHD's mental and physical restlessness disturbs a person's sleep patterns — and the ensuing exhaustion hurts overall health and treatment. This is widely accepted as true.
However, it can also lead to potential misinterpretation of symptoms. Take, for example, ADHD. While most people associate ADHD with hyperactivity and impulsivity, it can also manifest in more subtle ways, such as through intrusive thoughts and overthinking.
Scripting is the repetition of words, phrases, or sounds from other people's speech. Most commonly scripting phrases and sounds are from movies, tv, or other sources like books or people they interact with. Scripting is especially common in children on the spectrum who are learning to talk.
Especially for children, ADHD and eye contact using don't work together too well. Many people with ADHD struggle with social skills in general. Typically, they find it difficult to understand other's emotions, which makes empathy a challenge.
While cognitive empathy can be lower in people with autism, affective empathy—which is based on instincts and involuntary responses to the emotions of others—can be strong and overwhelming. In fact, newer research suggests that some people with autism may actually feel other people's emotions more intensely.
