Comprehensive Neuropsychiatric ADHD Care in McHenry County
Help With ADHD
At Kohn Brain Clinic, we approach Attention-Deficit/Hyperactivity Disorder (ADHD) through a specialized neuropsychiatric lens—evaluating the intricate connections between brain biology, psychological temperament, and lifestyle factors.
Led by board-certified neuropsychiatrist Dr. Robert Kohn, D.O., our comprehensive care paths utilize advanced objective data, including T.O.V.A. (Test of Variables of Attention) testing, to build personalized treatment protocols combining medical management, lifestyle therapy, and genetic insights for patients of all ages.
Here is how T.O.V.A. testing works.

Types of ADHD / ADD
There are 3 types of ADHD / ADD recognized by the following DSM-V criteria:
Inattentive Type
Often described as lost
in thoughts, forgetful,
a daydreamer
Hyperactive-Impulsive
Often described as fidgety, difficult to control,
'on the go'
Combined Type
Often presents with both inattentive and hyperactive
symptoms
Common ADHD Characteristics
Symptoms of ADHD vary greatly from person to person but generally include at least 2-3 of the following characteristics.
Diagnosing ADHD Patients
The first step in getting treatment for ADHD, either for yourself or your child, is to be properly diagnosed. This usually starts with a visit to your family doctor for a thorough behavioral assessment.
Additionally, further assessments from people that know the patient well help inform and formulate a proper diagnosis of the patient. There are several standardized guidelines that can be used for these assessments. One of the most common resources used is the Diagnostic & Statistical Manual of Mental Disorders, Fifth Edition, or DSM-5.

Advanced Objective Diagnostics
Traditional ADHD diagnosis relies heavily on subjective questionnaires. At Kohn Brain Clinic, we eliminate the guesswork by combining two of the most trusted, evidence-based digital diagnostic platforms available:
The T.O.V.A. Test (Test of Variables of Attention)
A gold-standard, FDA-cleared continuous performance test that measures attention, focus, and impulsivity. By analyzing exact response times to visual or auditory stimuli, T.O.V.A. provides an objective baseline of central nervous system function.
Creyos Cognitive Profiling
A comprehensive digital testing platform designed to map core executive functions, short-term memory, and cognitive processing speed. Creyos allows us to see exactly how ADHD impacts your day-to-day brain performance.
Why Choose a Neuropsychiatric Approach for ADHD?
Because ADHD is a complex neurobiological spectrum condition deeply tied to executive functions, treating it successfully requires looking at both neurological pathways and psychiatric behaviors. Kohn Brain Clinic is uniquely positioned in providing superior, neuro-psychiatrist care for complex ADHD cases.
