F98: Other behavioural and emotional disorders with onset usually occurring in childhood and adolescence

The group of conditions referred to as 'Other behavioural and emotional disorders with onset usually occurring in childhood and adolescence' comprises various disorders that start during developmental years. Often, these conditions reveal themselves through behaviours such as aggression or withdrawal, and symptoms can include fearfulness, repetitive behaviours, sleep disturbances, and difficulties with attention. They are not transmitted through contact, rather they can be influenced by several factors such as genetics, irregular brain function, and certain environmental factors like trauma or abuse. The progression of these disorders varies widely; some might improve as the child grows older, while others can continue into adulthood. They mainly affect the neurological and psychological systems, impacting a child's emotional health and daily functioning.
