Take a screening test to determine if you have the symptoms ADHD. There are many tests available online (see Resources) that will provide you immediate results; but be aware that these are only screening tools for the symptoms commonly experienced by those who have ADHD and can not be substituted for a medical diagnosis.
Call your medical doctor if you suspect that you have ADHD. A diagnosis will require ruling out any other medical conditions. Answer all questions honestly and cooperate with your doctor's requests. Although you may not think it is necessary to complete the medical tests he orders, it is vital to document that no other medical conditions exist that could be causing the symptoms.
Ask for a referral to a professional who has experience in dealing with adult ADHD. A psychologist can evaluate and diagnose the condition, but keep in mind that only a psychiatrist or a medical doctor can prescribe any required medications.
Keep all appointments and follow the doctors instructions prior to any testing. You may be asked to have an MRI to monitor brain functioning and may be asked to refrain from sleeping for a specified amount of time prior to the test. Be prepared to take and EEG test to monitor brain waves.
Participate fully will any psychological testing and be honest with all your answers. Support your spouse or family members, as they will be asked to provide an assessment of your functioning in the family, or may be asked about your work history or other factors that may influence the diagnosis. Encourage them to be honest and do not try to influence their answers. It may be difficult for your spouse to answer the questions honestly and she may be afraid of hurting your feelings. Do not ask her how she answered the questions.
Follow the doctor's recommendations if/when the diagnosis is made.
