Neurodiversity and Co-occurring differences

Attention Deficit (Hyperactivity) Disorder (ADD/ADHD)

Signs of Attention Deficit (Hyperactivity) Disorder include inattention, restlessness, impulsive, erratic, unpredictable and inappropriate behaviour, blurting out inappropriate comments or interrupting excessively. Some people come across unintentionally as aggressive. Most fail to make effective use of feedback.

If no hyperactivity is present, the term Attention Deficit Disorder should be used: these individuals have particular problems remaining focused so may appear 'dreamy' and not to be paying attention. People with this condition are very easily distracted, lose track of what they are doing and have poor listening skills. By failing to pay attention to details, they may miss key points.
