F78: Other mental retardation
The group of conditions classified as Other Mental Retardation encompasses forms of cognitive impairment not falling into the specifically identified categories. These conditions are generally lifelong and may manifest early in a person's development, typically affecting learning abilities, cognitive function, and problem-solving skills. A variety of genetic and environmental factors can contribute to their development, examples being chromosomal abnormalities or prenatal exposure to substances that harm neurological development. Symptoms may vary greatly among individuals but can include significant limitations in intellectual functioning - such as reasoning, learning, and problem-solving - and adaptive behavior, affecting daily life and social activities. Progression of these conditions depends on multiple factors like the severity of the impairment and the type of supportive resources available. These conditions affect the central nervous system and broadly speaking, the cognitive and behavioral aspects of the individual's health profile.
