A degenerative nervous disorder occurring mostly in persons older than 60 years, characterized in advanced stages by rhythmic muscular tremors, especially in the hands, and by rigidity of movement, a drooping posture, slow speech, and a masklike facial expression; the term designates a set of symptoms, and the underlying disease causing these symptoms is most commonly Parkinson's disease. Parkinsonism results from a deficiency in the neurotransmitter dopamine caused by degeneration of the cells producing that agent. It can be mitigated by chemotherapy with agents such as levodopa (3-hydroxy-L-tyrosine).
A group of symptoms that include tremor, rigidity, bradykinesia, stooped posture, and shuffling gait. The more common causes of Parkinsonism are Parkinson's disease, striatonigral degeneration, and a reversible condition induced by certain drugs.
Tremor, muscular rigidity, or absence of movement that occurs as a side effect of antipsychotic medication.
A neurologic disorder characterized by tremors, muscle rigidity and slow movements
A group of neurological disorders characterised by hypokinesia, tremor and muscular rigidity.
A constellation of the following symptoms: tremor, rigidity, bradykinesia (slow movements), and loss of postural reflexes. Although classically seen in Parkinson's disease, parkinsonism may have other causes. In the elderly, parkinsonism may be caused by dopamine-blocking drugs, multiple system atrophy, striatonigral degeneration, Shy-Drager syndrome, cortico basal degeneration, diffuse Lewy body disease, and Alzheimer's disease with parkinsonism. In younger people, parkinsonism may be caused by juvenile-onset dystonia/parkinsonism, Westphal variant of Huntington's disease, Wilson's disease, L-dopa-responsive dystonia, Hallervorden-Spatz disease, and progressive pallidal degeneration.
Copyright © 1996-97 The National Parkinson Foundation, Inc]. Parkinson's disease (PD) is a chronic neurological condition first described in the early 19th century. Parkinsonism is a slowly progressive disease that affects a small area of cells in the mid brain. Gradual degeneration of these cells causes a reduction in a vital chemical known as "dopamine". In typical Parkinson's disease the signs are: tremor on one side of the body when it is at rest; slow movement; stiff limbs; and problems with walking and balance problems.

A clinical state characterised by tremor, rigidity, bradykinesia, stooped posture, and shuffling gait. The more common causes of Parkinsonism are Parkinson's Disease, striatonigral degeneration, and a reversible syndrome induced by major tranquillising drugs.
a degenerative disorder of the central nervous system characterized by tremor and impaired muscular coordination
A motor disorder resulting in stiffness, slowness, difficulty arising, tremor and masking of the facial features. Parkinsonism can be caused by neuroleptics or by damage to dopamine-producing nerve cells in the brain stem.
Refers to a group of conditions which feature the main symptoms of parkinsonism (tremor, rigidity and akinesia). Parkinson's disease is the most common form of parkinsonism. Other, less common forms include multiple system atrophy (MSA) and Progressive Supranuclear Palsy.
the name given to a group of disorders with similar features -- four primary symptoms (tremor, rigidity, postural instability, and bradykinesia) that are the result of the loss of dopamine-producing brain cells.
the term used to describe movement disorders characterized by similar symptoms to those of idiopathic Parkinson's.
A group of motor symptoms and/or general slowness that is similar to PD. In addition to PD, several diseases and a number of medications generate this appearance
Relating to symptoms displayed in Parkinson's disease.
a term referring to a group of conditions that are characterized by four typical symptoms--tremor, rigidity, postural instability, and bradykinesia. postural instability: impaired balance and coordination, often causing patients to lean forward or backward and to fall easily. retropulsion: the tendency to step backwards if bumped from the front or upon initiating walking, usually seen in patients who tend to lean backwards because of problems with balance.
brain disorder affecting involuntary twitches, tremors, unusual walk, Parkinson's disease.
A side effect of antipsychotics (or neuroleptics) characterized by awkward and stiff facial movements.
(par-kin-son-izm): A group of symptoms including loss of movement, a lack of facial expression, stiff gait when walking, tremor, or stooped posture. These symptoms are sometimes side effects of certain antipsychotic medications. (Sometimes referred to as EPS).
Generic term referring to slowness and mobility problems that look like Parkinson's disease. Several conditions, such as multiple system atrophy and progressive supranuclear palsy, and a number of medications produce this appearance.
Group of three diseases with similar symptoms as above but with some differences; may reflect damage to different processes or sites.
A group of neurological diseases characterized by weakness, tremor, and muscular rigidity. Believed to be due to a deficiency of dopamine in the basal ganglia of the brain.
Parkinsonism describes the common motor symptoms of Parkinson's disease: tremor, rigidity, akinesia or bradykinesia and postural instability.
