It may involve other medical conditions like anxiety , learning disorder, autism spectrum disorder and tics.
Risk factors for ADHD:
Family history, prematurity, very low birth weight, drinking alcohol in pregnancy,...Obviously drinking alcohol or other contact with toxins during pregnancy is preventable. Family history which is one or two parents with history of ADHD plays an important role.

His teacher does not report any hyperactivity or difficulty with him at school. He has at least 9 hours of sleep per night. Jennifer is sure that Liam's diet is diverse with sufficient nutrients and he is not a fussy eater. Liam does not show any nutritional deficiency symptoms.
Jennifer recently separated from her partner (Liam's father) who moved to Brisbane. It happens quickly and Liam has difficulty copping with new situation at home. Liam asks about his father frequently. Jennifer informed that Liam does not meet ADHD criteria but due to anxiety/adjustment difficulty needs further assessment with multidisciplinary team ( GP, Paediatrician, Practice nurse and Child psychologist). Liam had psychological evaluation and detailed assessment including ADHD tests by paediatrician. It came back as adjustment disorder and stress due to his parents separation. His psycho-educational assessment does not show any learning difficulties or inattention for tasks at hand. Jennifer is happy to take Liam to counselling to help him to cope with separation of his parents.
