ADHD symptoms can vary widely. Generally, the most commonly described symptoms include:
- Inability to pay attention to details
- Difficulty organizing and completing tasks and activities
- Physical restlessness
- Trouble staying seated
- Impulsivity (saying or doing things without considering the consequences)
- Procrastination
Learning and behavioral disorders, pervasive developmental disorders, and mood disorders, often associated with ADHD in children, can persist into adulthood. Generally, in adults, there's a partial change in the clinical characteristics of the disorder, determined by individual developmental progression.
The most prevalent and debilitating characteristic tends to be related to attention difficulties, while hyperactivity aspects change and remain primarily linked to impulsivity and an internal feeling of restlessness and/or unease.
For many adults with ADHD, symptoms may include excessive focus on irrelevant stimuli, or poor ability to organize both mental and behavioral processes in family and work settings. These types of symptoms can significantly impact daily life. While in children, symptoms like chronic inattention can be managed by parents, in adults, they can represent a major obstacle.
