April is Autism Awareness Month. Whether you or someone you know has autism, or whether you are just wanting to learn about autism and the brain, we at Minder Memory Center are here to help!

Here we will cover the basics about Autism Spectrum Disorder (ASD): what it is, signs and symptoms, how it is diagnosed and treated, and what you can do if you suspect you or a loved one may have ASD.
What Is Autism?
What Is Autism?
Autism is also called Autism Spectrum Disorder (ASD). It is a neurodevelopmental condition that affects how a person thinks, communicates, and relates to others, as well as their behavior and interests. It is called a “spectrum” because it can look different from person to person.

The amount that ASD affects an individual’s daily life varies. For example, some individuals with ASD may need a lot of help with daily tasks and may be nonverbal, whereas others may be high-functioning and have stronger verbal skills.
What’s Going On in the Brain?
What’s Going On in the Brain?
In ASD, the brain processes complex information differently. Scientists have found differences in how certain parts of the brain are connected in ASD.
Such changes in how the brain functions can affect abilities like:
Understanding social cues
Handling changes
Noticing details that others might miss
Managing strong emotions
Responding to sensory information (like sounds or lights)
Many factors are thought to affect an individual’s risk of ASD, including largely genetic factors, though scientists believe environmental factors may also contribute in some cases.
How Common Is ASD?
How Common Is ASD?
ASD is more common than many people think. According to a recent 2025 CDC report, about 1 in 31 children in the United States is diagnosed with ASD. Additionally, ASD is 3 to 4 times more common in males than females. It affects people of all races, cultures, and backgrounds.
What Are Some Common Signs?
What Are Some Common Signs?
ASD is diagnosed when someone has difficulty with social communication and interaction, in addition to restricted or repetitive interests and behaviors. These symptoms can show up in a variety of ways, so ASD can look different for everyone. Here are some common signs and symptoms:
Social communication and interaction:
Trouble with eye contact
Difficulty with back-and-forth in social conversations
Difficulty noticing others’ feelings or emotions
Difficulty with nonverbal communication (like facial expressions, body language)
Trouble making and maintaining relationships
Difficulty navigating social situations
Delays in language
Social communication and interaction:
Repetitive behaviors (like flapping hands, repeated movements, or lining up toys)
Repetitive speech or words
Fixation or strong interest in one topic
Feeling distressed by changes in routine
Feeling overstimulated (or, alternatively, under-reacting) to sensory information (like sounds, lights, or textures)
Having these signs or symptoms does not always mean someone has ASD. ASD is diagnosed after a thorough evaluation by a healthcare provider. Ultimately, diagnosis depends on the number and extent of symptoms and signs, as well as other aspects of an individual’s history.

When and How Is ASD Diagnosed?
When and How Is ASD Diagnosed?
Signs and symptoms may differ from person to person and are evident early in life, typically in the first 2 years. Some individuals can begin to show signs and symptoms at about 6 to 12 months, though others have symptoms that are noticed later in childhood. The American Academy of Pediatrics recommends screening for ASD at 18 and 24 months.

If there are concerns for possible ASD, an individual may be referred to a specialist (such as a psychologist or neuropsychologist) for evaluation.  Generally, ASD can be diagnosed around 18-24 months of age or later, though some individuals remain undiagnosed - including some adults and individuals with high-functioning ASD.

Testing for ASD may consist of interviews, questionnaires, neuropsychological tests, and observation-based assessments that look at social skills, cognition, and behavior.

ASD can co-occur with other conditions (such as intellectual disorders, ADHD, anxiety, depression, etc.), and can be associated with difficulties in aspects of thinking (such as attention, complex thinking, verbal abilities, etc.), so comprehensive assessment of an individual’s social, behavioral, developmental, adaptive, and cognitive skills can help with diagnosis and treatment planning.
What Kinds of Support are Available?
What Kinds of Support are Available?
Treatments and supports for individuals with ASD depend on the individual’s cognitive, communication, social, behavioral, and daily functioning.

According to the CDC, some of the most common treatment approaches include:
Applied Behavior Analysis (ABA) – to help with teaching new skills and behaviors (like daily living and communication skills), as well as reducing problematic or unhelpful behaviors.
Speech Therapy – to help with language and communication.
Occupational Therapy – to help with daily tasks (like self-care) and sensory processing.
Educational Services – adapted approaches to learning in the classroom, often emphasizing visual learning.
Social & Relational Interventions – to help learn social skills.
Cognitive Behavioral Therapy (CBT) – to help with emotional symptoms like anxiety or mood difficulties.
Why Early Help Matters
Why Early Help Matters
In general, earlier intervention is associated with better outcomes. Getting the right help early on can support learning, build confidence, and make life smoother at home, school, and in the community.
What You Can Do
What You Can Do
There is no known way to prevent ASD.  Instead, the focus is on early diagnosis and intervention.  If you or a loved one are showing signs or symptoms of ASD, talk with a healthcare provider.

A neuropsychological evaluation with a provider who specializes in ASD can help with:
Getting an accurate diagnosis
Learning how a person’s brain works
Developing personalized recommendations
Making a plan for school, work, home, and daily life
Understanding more about yourself or your loved one is the first step to getting the right support. You don’t have to figure it out alone — there are professionals who can help guide the way.
