Minimal brain dysfunction is a neurological disorder that affects the functions of the brain. It is characterized by symptoms such as hyperactivity, impulsiveness, and difficulty in focusing. However, the term 'minimal brain dysfunction' has been replaced with more modern terms such as Attention Deficit Hyperactivity Disorder (ADHD) and Specific Learning Disorder (SLD). These definitions better describe the condition and eliminate negative connotations associated with the term. Other synonymous terms for minimal brain dysfunction include hyperkinetic syndrome, developmental coordination disorder, and attention deficit disorder. The advancement of research into this disorder has led to more accurate diagnoses and appropriate treatments that offer patients a better chance at life improvement.
