ADHD symptoms & assessment

The most common symptoms of ADHD are:


Sufferers are easily distracted, prone to daydream, do not finish work, have problems listening, and some are clumsy.


These include acting before thinking of the consequences, jumping from one activity to another, disorganization, and a tendency to interrupt other people’s conversations.


Sufferers experience restlessness, often characterized by an inability to sit still for long, fidgeting, climbing on things, and troubled sleep.

ADHD may also accompany other disorders

Some of the other associated conditions with ADHD include:

  • Oppositional defiant disorder and conduct disorder – both disorders are characterized by anti-social behavior. Examples of this behavior might include aggression, stubbornness, stealing, lying, frequent temper tantrums, and general deceitfulness. Oppositional defiant disorder occurs in around 35% of sufferers, and conduct disorder occurs in around 25%.
  • Obsessive-compulsive disorder (OCD) – shares many of the same characteristics as ADHD, as well, and it is commonly believed to be a generic component.
  • Bipolar disorder (previously called manic depression) – occurs in around 25% of children with ADHD.  These children may show signs of behavioral problems, including being overly aggressive.
  • Anxiety disorder – more likely in girls than boys, especially those with a subtype of ADHD known as inattentive ADHD.
  • Mood disorders – more frequently diagnosed in boys with the combined subtype of ADHD.
