icd 10 code for rapid onset dystonia parkinsonism

Full Answer

What is rapid-onset dystonia-parkinsonism (RDP)?

Background and objectives: Rapid-onset dystonia-parkinsonism (RDP) is caused by mutations in the ATP1A3 gene, which codes for the α-3 subunit of the Na+/K+ATPase. It has been characterized by rapid-onset bulbar dysfunction, limb dystonia, bradykinesia, and a rostrocaudal spatial gradient of expression, usually after a physiologic trigger.

Epidemiology

The prevalence is unknown. Fewer than 100 patients have been described worldwide to date.

Clinical description

RDP typically presents in childhood or early adulthood (but age of onset can range from 4-55 years) with the abrupt onset of dystonia along with parkinsonism (bradykinesia and postural instability) with a rostrocaudal gradient and prominent bulbar symptoms (dysarthria and dysphagia) that do not respond to dopaminergic medication.

Etiology

RDP is caused by several missense mutations in the ATP1A3 gene (19q13.2) encoding the sodium/potassium-transporting ATPase subunit alpha-3 protein, which is important for maintaining the electrochemical gradients of potassium and sodium across the plasma membrane. These mutations are thought to lead to neuronal dysfunction.

Diagnostic methods

Diagnosis is based on the sudden onset of clinical manifestations (parkinsonism and dystonia), the finding of low homovanillic acid concentrations in cerebrospinal fluid (CSF), normal brain imaging studies and the lack of response to levodopa (L-dopa) therapy.

Differential diagnosis

Differential diagnosis includes other forms of dystonia-parkinsonism, such as young adult-onset parkinsonism, dopa-responive dystonia (DRD), dystonia 16 (DYT16) and X-linked dystonia parkinsonism (DYT3). Unlike DYT3 and other forms of young-onset parkinsonism, RDP is not a neurodegenerative disorder.

Antenatal diagnosis

Prenatal diagnosis is possible in families where a disease causing mutation is known.

What is the third category of medication for PD?

The third category of drugs prescribed for PD includes medications that help control the non-motor symptoms of the disease ; that is, the symptoms that don't affect movement. For example, people with PD-related depression may be prescribed antidepressants.

What is the second category of PD drugs?

The second category of PD drugs affects other neurotransmitters in the body in order to ease some of the symptoms of the disease. For example, anticholinergic drugs interfere with production or uptake of the neurotransmitter acetylcholine. These can be effective in reducing tremors.

What are the most common drugs for PD?

The first category includes drugs that increase the level of dopamine in the brain. The most common drugs for PD are dopamine pre cursors—substances such as levodopa that cross the blood-brain barrier and are then changed into dopamine.
