Movement disorders are neurological conditions that lead to excess movement or a decrease in movement. The following are among the movement disorders sometimes associated with Parkinson's disease symptoms:
Progressive supranuclear palsy (PSP). PSP is a brain disorder that affects walking and balance, often resulting in falls. The condition can also cause problems with vision and eye movement. PSP does not usually respond to medication.
Multiple system atrophy (MSA). MSA is a rare, progressive nervous system disorder that may share some of the same symptoms as Parkinson's disease. Other symptoms of MSA may include poor coordination, slurred speech, problems with breathing and swallowing, and constipation. Parkinson's medications may provide some relief.
Viral parkinsonism. Some viral diseases, such as encephalitis lethargica (sleeping sickness), Western equine encephalomyelitis, Eastern equine encephalomyelitis, and Japanese B encephalitis ? all infections of the brain ? have been known to cause Parkinson's-like symptoms.
Drug- and toxin-induced parkinsonism. Being exposed to certain medications, like Thorazine (chlorpromazine), Haldol (haloperidol), Reglan (metoclopramide), reserpine, and Depacon (valproate), or toxins such as manganese dust, carbon disulfide, and carbon monoxide, can bring on Parkinson's disease symptoms. But these symptoms normally subside once you stop taking the medication or stay away from the toxin.
Arteriosclerotic parkinsonism. Sometimes the brain damage incurred by small strokes can lead to Parkinson's?like symptoms. When this is the case, Parkinson's disease medication will not alleviate the symptoms.
Parkinsonism-dementia complex of Guam. This disease affects the indigenous people of Guam and the Mariana Islands. Unlike people with Parkinson's disease, who do not usually die of the disease, people with parkinsonism-dementia complex of Guam typically die within five years.
Post-traumatic parkinsonism. Parkinson's disease symptoms that result from severe or frequent head injuries are referred to as post-traumatic parkinsonism. This condition can also be associated with dementia. Boxers, other athletes, and people whose professions put them at increased risk for blows to the head may be susceptible to this condition.
Cortical basal ganglionic degeneration (CBGD). CBGD occurs when the areas of your brain known as the cerebral cortex and the basal ganglia waste away. As with Parkinson's disease, rigidity and impaired balance may begin on one side of the body and eventually spread to the other side. However, unlike Parkinson's, CBGD does not usually respond to treatment with medication.
Lewy-body disease. Lewy bodies are abnormal proteins that disrupt neurological functioning and deplete dopamine levels in the brain. They can lead to symptoms like those of Parkinson's and Alzheimer's disease, as well as to hallucinations, delusions, and sometimes depression. Parkinson's disease medication can ease some Lewy-body disease symptoms, but these medications tend to make hallucinations and delusions more severe.
Essential tremor. An essential tremor produces tremors, or uncontrolled shaking, in the hands and sometimes the head, that progress over time. The tremor is not associated with other Parkinson's disease symptoms. Certain medications can be helpful in managing an essential tremor, but Parkinson's disease medication is not effective.
Normal pressure hydrocephalus (NPH). A build up of fluid within the brain may cause difficulties with walking and balance, which might be confused with Parkinsoní»s disease. Usually, there will also be signs of dementia and loss of bladder control with this disorder, though. Once diagnosed, NPH can be cured with the placement of a shunt to drain excess fluid.
