Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Attention deficit disorder has many symptoms including, but not limited to, forgetful of daily activities, losing things, not listening, easily distractible, making careless mistakes, fidgets, hyperactive, talking excessively, interrupts others, and avoids activities that require mental function. Many people may not know that they have this condition until it is noticed in school or work. The diagnosis requires a full multimodal assessment that involves visiting with the patient (or parents if it is a child), and questionnaires to those around the patient. The TOVA test has been created to help with diagnosis but it is not a perfect test. Thus, it should be used in combination with other assessments. The diagnosis is ultimately made by meeting DSM-IV criteria and excluding other causes. Because of your hearing of music, you may also discuss with your physician if there is any indication to have an EEG which assesses the electrical nature of your brain to ensure there are no seizure-like activity.
I would suggest you follow up with your primary physician. You may need referral to a psychiatrist for further diagnosis/management.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
