Symptoms of ADHD

Symptoms of ADHD: Introduction

Symptoms of ADHD are categorized into those of inattention, hyperactivity, and impulsivity. These categories of ADHD are the same for children and adults although they may exhibit symptoms in different ways.

Symptoms of inattention include an inability to stay focused on tasks appropriate for age, having difficulty concentrating on one thing, loosing important items, and daydreaming. Other symptoms of inattention include not making eye contact when spoken to, having difficulty with following instructions, and becoming quickly bored with a task or activity.

Symptoms of hyperactivity include excessive talking, inability to sit still even during short periods, and being constantly on the move, running, jumping, or screaming.

Symptoms of impulsivity include impatience, showing excessive emotions, and frequently interrupting others.

People with ADHD can exhibit any combination of these symptom types. Some people may be more difficult to diagnose because they primarily exhibit the symptoms of inattention, such as daydreaming and losing items, but not symptoms of hyperactivity. People may also primarily exhibit symptoms of hyperactivity and impulsivity or of all three symptom categories.

Children do not simply grow out of ADHD, as is often believed. Just the opposite is commonly true - the symptoms of ADHD often get worse as a child grows into adulthood....more about ADHD »

Wrongly Diagnosed with ADHD?

The list of other diseases or medical conditions that may be on the differential diagnosis list of alternative diagnoses for ADHD includes:

  • Normal child behavior - not every active child is actually hyperactive; not every shy child is inattentive; not every day-dreaming child is inattentive. Babies and small children have a very short attention span and children are still easily distracted until they are older.
  • Giftedness (High intelligence) - gifted children may be bored or restless in class giving the appearance of symptoms similar to ADHD.
  • Normal behavior - sometimes normal children act hyperactive or inattentive without any disease.
  • Bipolar disorder - hyperactivity could be from the mania from bipolar disorder.
  • Restless legs syndrome - fidgeting and moving legs may be misdiagnosed as hyperactive ADHD.
