Psychological Evaluations for Autism and ADHD
Comprehensive Psychological Testing for Autism (ASD), ADHD, and other mental health conditions.
For many adults, the decision to pursue a psychological evaluation comes after years of feeling that something has been difficult to explain. You may have always struggled with focus, organization, time management, sensory overwhelm, social expectations, emotional regulation, or maintaining routines. You may have developed effective ways to compensate, only to find that those strategies become harder to sustain during periods of stress, burnout, increased responsibility, or major life change.
Dr. Hosanna Bonn provides comprehensive psychological evaluations for adults who are seeking greater clarity about possible Attention-Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), or other psychological concerns.
An evaluation is not simply about receiving a diagnosis. It is an opportunity to better understand how your mind works, why certain areas of life may feel more difficult, and what kinds of support may be most helpful moving forward.
Adult ADHD Evaluations
ADHD can affect much more than attention. Adults with ADHD may experience difficulty with task initiation, working memory, time awareness, organization, follow-through, emotional regulation, impulse control, and shifting between activities. Some people are able to focus intensely on topics that interest them while struggling to begin tasks that feel repetitive, unclear, or overwhelming.
Many adults with ADHD were not identified in childhood. Their symptoms may have been overlooked because they earned good grades, appeared responsible, developed strong coping strategies, or did not display obvious hyperactivity. Others may have been described as forgetful, unmotivated, overly emotional, inconsistent, disorganized, or capable but not reaching their potential.
A comprehensive ADHD evaluation can help determine whether these experiences are best explained by ADHD, another condition, or a combination of factors. It can also help distinguish ADHD from concerns that may appear similar, including anxiety, depression, trauma-related symptoms, sleep difficulties, learning differences, or chronic stress.
Adult Autism Evaluations
Autism can present differently in adulthood than many people expect. Some adults have spent years consciously studying social expectations, rehearsing conversations, copying the behavior of others, or suppressing natural reactions in order to fit in. This process is sometimes referred to as masking or camouflaging.
Adults seeking an autism evaluation may describe feeling socially exhausted, misunderstood, overly sensitive to sounds or textures, deeply reliant on routines, intensely focused on particular interests, or unsure how to navigate unspoken social rules. They may also experience burnout after prolonged periods of meeting expectations that do not come naturally to them.
Some adults begin considering autism after a family member is diagnosed, after learning more about neurodivergence, or after recognizing that previous explanations never fully captured their experience. An evaluation can offer a more complete understanding of lifelong patterns in communication, sensory processing, relationships, routines, interests, and emotional functioning.
ADHD and Autism Can Overlap
ADHD and autism are distinct conditions, but they can also occur together. When both are present, a person may experience competing needs. For example, they may crave structure but struggle to maintain it, seek novelty while also becoming overwhelmed by change, or desire connection while finding social interaction exhausting.
Because ADHD, autism, anxiety, trauma, mood concerns, and personality patterns can overlap, a thoughtful evaluation looks beyond a checklist of symptoms. The goal is to understand how different experiences interact and which explanation best fits the person’s history and current functioning.
