It's not just a case of a few too many espressos. Adult Attention Deficit Disorder can be devastating . Now wait a minute--if you didn't have the symptoms as a kid you can't have the disorder now. In fact, as an adult you've probably have a handle on the hyperactivity part. It's the inattention that wreaks havoc in your life. The struggle to gather together the focus you need to get to where you want to go in life--work, family, creativity--everything can be a a mass of confusion and chaos when you suffer from Attention Deficit Disorder as an adult.
In fact, it wasn't even a disorder until 1980. By 1998 even the American Medical Association relented and agreed it really was a developmental disorder. Lots of individuals who suffer from this disorder continue to have problems as adults. The problem resides in the frontal lobe of the brain where the executive functions reside. Here is where you plan, organize, and marshal your forces to achieve the goals you have made for yourself. When this area of the brain is not as active as it needs to be, you simply are not able to put things together and make things happen.
WHAT CAN I DO?
You need to get a solid assessment and testing to help confirm the diagnosis. After that, it's a look at treatment. It's considered a behavioral handicap with no cure, but don't despair. Medication is the treatment of choice for severe symptoms. Moderate symptoms may be handled through a prosthetic environment. This simply means you compensate for your forgetfulness by using a calender and writing things down; and by developing routines like always putting your keys in the same place or a checklist of everything you need before you head to work.
CREATIVITY OR MANIA?
If you feel you really are too "hyper"; then you need to evaluate if you're experiencing a Manic Episode and suffering from Bipolar Disorder rather than Attention Deficit Disorder. If you find you're escalating to a near continual state of euphoria without the need to sleep; then it may be time to talk to your physician. While it may naturally occur during a creative burst of energy, the aftermath and inevitable crash may be worse that the art you created.
What types of distractions keep you from the goals you want to achieve?
