Assessment of Your Condition
Dr.Robert Kohn knows that the proper diagnosis leads to the proper treatment. He
assesses your symptoms using his Biological-Psychological-Social framework,
explained in Our Approach to Healing.
Using a variety of the following Assessment Tools, information is gathered which is vital to a successful outcome.
Quotient test is a patented continuous performance computer test that gathers
information on head and leg motion, attention, focus, inhibition and timing. It
is an extensively well-studied test that references children, teens and adults
with ADHD/ADD compared to controls. Dr. Kohn uses Quotient testing in his
evaluation of ADHD/ADD as well as evaluating complaints of attention processing
in other disorders such as Mood Disorders, Traumatic Brain Injury, Tourette Syndrome
The IVA+Plus test is a computer based continuous performance test that compares
visual and auditory attention skills of focus, discrimination and maintenance
of attention. In his practice, Dr. Kohn uses the IVA+Plus for the same
conditions that the Quotient Test is used for. These include ADHD/ADD, Mood Disorders,
Traumatic Brain Injury, Tourette Syndrome and Autism.
NEO 5 Factor Personality Test
The Neo 5 is a computerized analysis of five core personality traits. Each trait is measured in a range of much less than average to
much more than normal. The five traits include:
Neuroticism- the dimension of self discontent, emotional turmoil
Extroversion- the dimension of social connectedness
Open Mindedness- the dimension of mental flexibility and curiosity to novelty
Agreeableness- the dimension of interpersonal alignment that includes cognitive and emotional flexibility
Conscientiousness- the dimension of mental, emotional and physical persistence in pursuit of goals.
overall report has clinical relevance to both emotional and cognitive disorders
seen in mental illness or brain injury. Dr Kohn uses this test with older teens
Brain SPECT Scan
Listen to Dr. Kohn.
The Brain SPECT Scan is a nuclear medicine test. It measures blood flow in the brain
which is directly related to brain activity.
Brain SPECT Scan is used as a tool in the clinical evaluation process to help view areas of brain activity and relate
them to presenting symptoms. Symptoms and signs are clustered based in part, on
the brain networks activated.
Symptoms include those observations made by the person or parent, while signs refer to those findings
noted on clinical examination. Common symptoms include sadness, anger, rage,
worry, obsessions-compulsions, fear-panic, fatigue, loss of motivation or will,
distractibility and inattention. Common signs include weight loss, agitation,
mood lability, illogical, tangential or circumstantial thinking.
The human brain is a system of interconnections that coordinate the many functions that make us who we are;
our personality, our aptitude, our interests, our emotional state, etc. The
working of one brain region is networked to process information from other regions.
Like a traffic officer that directs cars to move in and out of an intersection;
brain systems allow one part to function or "come on line" while
influencing another part to decrease its function or "come off line".
Using Brain SPECT Scan imaging in the field of neurology and psychiatry allows visualization of these brain regions
in action (blood flow). While there are patterns that are common to each
diagnosis, patterns often overlap. This is seen clinically as the phenomenon of
Dr. Kohn uses the Brain SPECT Scan to assess Traumatic Brain Injury and many other conditions.
Dr. Kohn is using the Brain SPECT Scanner at the University of Illinois in Chicago, and no longer provides in-house scanning.
The QEEG is a digital analysis of an EEG. The "quantitative analysis" of
the EEG creates a map of brain wave frequency distributions that range from 1
Hz to more than 30Hz. This map is used to direct the location for treatment and
type of Neurofeedback Therapy.
An example of this technique may include applying Neurofeedback to increase the brain wave frequency over an area
of localized brain wave slowing (due to an injury) or to decrease the brain
wave frequency over an area of localized brain wave increase (due to clinical
evaluates circadian rhythms in Sleep, Mood Disorders and ADHD/ADD. It is a
technique that uses a wrist monitor to measure body movements in states of
acceleration or deceleration. The device records information over a period of
wakefulness and sleep for at least 24 hours. The overall motion pattern
analysis is compared with populations of persons with Sleep Disorders, Mood Disorders
and ADHD/ADD. A report, helping to clarify the diagnosis, is completed based on
the likelihood of a clinical correlation with the above conditions.
Keirsey Temperament Inventory (Coming Soon)
The Keirsey Inventory is a computerized personality assessment based on the work of
David Keirsey. It is used with older teens and adults. He identifies four
general temperaments that include the following
The analysis of personality type or temperament is a useful tool in determining the meaning of one's symptoms in social settings.
Symptoms include behaviors, feelings and thoughts that are expressed across settings such as romance, friendship, career, family, hobbies,etc.
