Which diagnosis fits a 51-year-old man who cannot sit still, starts tasks but rarely completes them, and makes risky decisions?

The diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) is fitting for a 51-year-old man who exhibits symptoms such as an inability to sit still, difficulty completing tasks, and a propensity for making risky decisions.

ADHD is characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning or development. The symptoms described—restlessness, starting but not finishing tasks, and engaging in risky behaviors—align well with the impulsivity and inattention aspects of ADHD.
