Although not always the case, some children may also have signs of other problems or conditions alongside ADHD, such as:

• anxiety disorder – which causes your child to worry and be nervous much of the time; it may also cause physical symptoms, such as a rapid heartbeat, sweating and dizziness
• oppositional defiant disorder (ODD) – this is defined by negative and disruptive behaviour, particularly towards authority figures, such as parents and teachers
• conduct disorder – this often involves a tendency towards highly antisocial behaviour, such as stealing, fighting, vandalism and harming people or animals
• depression
• sleep problems – finding it difficult to get to sleep at night, and having irregular sleeping patterns
• autistic spectrum disorder (ASD) – this affects social interaction, communication, interests and behaviour
• epilepsy – a condition that affects the brain and causes repeated fits or seizures
• Tourette’s syndrome – a condition of the nervous system, characterised by a combination of involuntary noises and movements (tics)
• learning difficulties – such as dyslexia
