G20-G26: Extrapyramidal and movement disorders

Extrapyramidal and movement disorders are a group of neurological conditions characterized by problems with movement, voluntary control over muscles, and coordination. They are typically linked to damage or disease in the extrapyramidal system, which is a part of the brain involved in motor control. These conditions can arise from various causes, such as genetic factors, brain injuries, infections, or exposure to certain medications. Common symptoms include tremors, rigidity, slow movements, and difficulty with balance. Some people might also experience involuntary movements or changes in their posture. Over time, these conditions can progress and the symptoms may become more severe. Different parts of the body can be affected, often making daily activities difficult to perform. Each specific condition within this group has its own unique course and set of characteristics.
