Movement disorders, stemming from central nervous system dysfunction, affect voluntary and involuntary movements. These include hypokinetic disorders, like Parkinson’s disease and akinetic-rigid syndromes (multiple-system atrophy and progressive supranuclear palsy), and hyperkinetic disorders, like tremor, chorea, akathisia, myoclonus and tics. These conditions are difficult to diagnose, and thorough clinical evaluation, imaging and specialised tests can help in reaching a diagnosis. Dystonia, marked by involuntary muscle contractions, varies in severity and profoundly impacts quality of life. Treatment options include medication, neurotoxin injections, deep brain stimulation, and other therapies. A multidisciplinary approach and ongoing research are crucial for improving outcomes and quality of life for those affected.
