Movement Disorders

Movement disorders affect people of all backgrounds, but Black Americans face unique challenges in diagnosis and care. Parkinson's disease, for example, is often underdiagnosed or diagnosed at later stages in Black patients, partly due to differences in access to neurologists and movement disorder specialists. Black patients are also less likely to be referred for advanced treatments such as deep brain stimulation. Stigma around symptoms such as tremors or involuntary movements can delay people from seeking care. Early diagnosis and access to specialized neurological care are important for managing these conditions and improving quality of life.

Overview

Movement disorders are a group of neurological conditions that affect the speed, fluency, quality, and ease of voluntary movement. They can cause either excessive or reduced movement, and include conditions such as Parkinson's disease, essential tremor, dystonia, Huntington's disease, and Tourette syndrome. These disorders are caused by changes in the brain, particularly in areas that control movement. Symptoms can range from mild tremors to severe disability, and treatment may include medication, physical therapy, and in some cases surgery.

Common Symptoms

Tremors or shaking, often in the hands, arms, or head

Unsteady balance or frequent falls
Difficulty walking or changes in gait
Jerky, uncontrolled movements (chorea)
Tics or sudden repetitive movements or sounds
Difficulty with fine motor skills such as writing or buttoning clothes
Changes in speech or facial expression
