ADHD Diagnostic Assessment
A diagnosis of ADHD is made by a trained health care professional, usually a psychiatrist or psychologist. Rating scales and neuropsychological tests are used in the evaluation.
The first step in assessing for ADHD is to collect information from multiple sources. The health care provider needs to know about the signs at school, at home as well as at work.
great post to read and Questionnaires
A doctor must interview patients and review a variety of details to determine ADHD. This includes a child's history of symptoms and how they affect their school or performance at work. For adults, it may include the family health history and personal health history and the results of any medical tests that have been taken. The American Psychiatric Association has published guidelines for diagnosing ADHD known as the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). These guidelines provide a list that a physician must identify in order to diagnose ADHD.
The interview process is often accompanied by standardized questionnaires designed to gauge the signs of ADHD. These scales of rating may be broadband or narrowband and may cover a broad range of symptoms or be focused on specific subscales. Rating scales for narrowbands typically have a shorter completion time and are more easy to score. Broadband rating scales are utilized to collect data for research studies and usually require professional training to interpret.
Some patients are reluctant to acknowledge that they have symptoms of ADHD, especially if they are well-educated or working in a high-level job. Others, on the contrary however, are insistent about having issues and offer convincing evidence of their challenges and a unique pattern of coping. The results of interviews and questionnaires can be combined into one report for the doctor, who could also utilize other assessment tools.
A behavioral test is useful for ruling out other conditions which could cause symptoms similar to ADHD. This includes certain kinds of learning disabilities, depression, anxiety, or medication side effects. A psychometric or neuropsychological test may be required if the doctor suspects that the patient has intellectual disability, other cognitive or memory impairments or an issue with speech or language. A physical examination may be required as well. If the symptoms are thought to be caused by a substance abuse disorder or alcohol use, the drug or alcohol usage must be assessed. These tests are usually performed as part of a complete examination that takes a few hours or longer. Patients should arrive to their appointment feeling rested and ready to spend time answering questions regarding their behavior, functioning, and family background.
Behavioral Tests
Often, the first step to diagnose ADHD is to conduct an interview with a health care professional. During the interview, the individual will be asked how ADHD symptoms affect their daily lives. The individual could be asked to explain other mental health issues they have faced in the past, like depression or anxiety. The evaluator may also ask about any medications the individual is currently taking. During the interview, it's important that people are honest and forthcoming.
The person being evaluated will likely ask the person about any relatives who have been diagnosed with ADHD or suffer from ADHD symptoms of their own. ADHD is a disorder that can be found in families. A person with a family background of ADHD has an 85% chance of develop the disorder.
After gathering all the data The evaluator will then proceed to conduct tests on behavior. Behavioral tests help to provide more objective evidence that the person might be suffering from symptoms of ADHD. These tests typically involve an evaluator asking the subject questions about their behavior in certain situations and then rating them. These ratings are compared with those of other individuals. The use of these kinds of ratings that are standardized helps ensure that the results are consistent and accurate.
There are a variety of standardized rating scales that can be used to determine the severity of ADHD symptoms. These scales vary from broad-band that aim to evaluate an individual's emotional and behavioral functioning as well as narrow-band scales that are designed to detect specific ADHD symptoms. A lot of these ratings are also accessible online.
Computerized tests are becoming more popular for diagnosing ADHD. These tests are called continuous performance tests (CPT). In this type of test, the subject is asked to complete a set of computer-based tasks that test their ability to pay attention to specifics. The examiner can then compare the results of this test to the results of other CPTs in order to help identify a possible diagnosis.
Tests for neuropsychological testing
To diagnose ADHD A thorough evaluation will include intelligence tests and neuropsychological assessments. These tests can help to identify weaknesses in the primary areas of ADHD symptoms, including executive functioning and working memory. Tests for intelligence are also used to evaluate cognitive strengths and weaknesses which may guide treatment planning.
In previous studies on neuropsychology people with ADHD were found to have impairments in different types cognitive test batteries. These impairments are typically seen in frontal lobe functions tests (e.g. Reversal learning, Tower of Hanoi, Stroop Interference Test). However, not all people with ADHD have these problems in the same manner. In fact, some individuals do not show any impairments in these tests in any way (Luo et al., 2014).
This is particularly true for clinical comparison groups, which are typically drawn from the local community and comprise people who meet the diagnostic criteria for another psychiatric disorder or do not have any psychiatric disorder but have reasons for referral. Despite the vast heterogeneity of cognitive differences that are observed in these groups, the results of this study support the notion that neuropsychological testing may have limited incremental value to distinguish adult ADHD from other psychiatric disorders during an assessment for clinical reasons.
The neurocognitive battery was used to assess the hypothesized deficits in adult ADHD. These tests included a number of simple attention/vigilance tasks, complex cognitive functions including working memory (NBV correct responses), inhibition/interference control (Go/No-Go omissions and Stroop Interference test naming interference) and cognitive flexibility (TMT part B/TMT part A, SWITCH task switch accuracy).
The neuropsychological tests in the present study confirmed prior ADHD adult findings, and confirmed the frontal lobe hypothesis for the disorder. This is in line with other research suggesting that multifactorial models are likely to be important in the etiology of ADHD and that the function of the frontal lobe could be a common deficiency. Additionally, the finding that the ADHD group and the clinical groups had similar cognitive function is consistent with previous behavioral and neuroimaging evidence that shows that frontal lobe dysfunction is common in the general population of psychiatric patients.
Medical Evaluation
If a teenager, child, or adult is having problems at school or home or is having issues with relationships It could be time to determine if the issue is ADHD or learning disabilities or stress. A medical evaluation can aid in determining the severity and type of symptoms and rule out other medical conditions such as seizures or thyroid disorders. A physical exam is usually the first step. it may include eye and hearing tests (for children) or the thyroid test for adults. Documents of previous testing as well as school reports and medical records are important because they aid medical professionals in determining the beginning.
Interviews and questionnaires can help doctors better understand the cause of a patient's issue. They may ask parents and teachers as well as the person's significant other and coworkers or friends. A standardized rating scale can provide information about the frequency and severity of symptoms. It is based on research that compares the behaviors of people with and without ADHD. Most clinicians will ask the patient as well as the partner to complete an assessment scale.
A specialist in the field of ADHD will employ a comprehensive approach to evaluate a person's symptoms. They will make use of a variety of sources of information, such as interviews and rating scales and they will stick to the prevailing criteria for diagnosing. They may recommend further evaluations like brain imaging, to determine any possible root cause for the symptom pattern.
It is essential that the doctor carefully review the symptoms in various settings as well as over a period of six months for adults. A diagnosis of ADHD requires a minimum of five established symptoms of inattention and/or hyperactivity/impulsivity. The expert should also look into whether the patient has comorbid problems, such as a depression or anxiety disorder that appear and feel similar to ADHD but do not respond to treatment with stimulants.
Consult your primary care physician or a mental health specialist to refer you to a specialist if you think that you or your children may have ADHD. You can also contact an organization that offers support in your area or a university-based hospital or graduate school in psychology for recommendations.
