This is what Grok said:
ADHD, or Attention Deficit Hyperactivity Disorder, is a neurodevelopmental condition that affects both children and adults. It is characterized by symptoms such as difficulty focusing, hyperactivity, and impulsivity. These symptoms can be severe enough to interfere with daily life and can persist into adulthood for many individuals.
There are three main types of ADHD: predominantly inattentive, predominantly hyperactive-impulsive, and a combination of both. The symptoms can vary in presentation and severity, but they all impact an individual's ability to concentrate, control impulsive behavior, and regulate emotions.
It is important for those who suspect they may have ADHD to seek a diagnosis and treatment from a healthcare professional. With proper support and management, individuals with ADHD can lead fulfilling and successful lives.
I personally disagree. See Grok's Beliefs on Stimulants.
