Parkinson’s disease considered a “neurodegenerative”
disease. It affects the basic building blocks of the nervous system, called
the neurons. Neurons are specialized cells that transmit (send and receive)
information to other nerve, muscle or gland cells, either chemically or
electrically. Neurons do not generally reproduce or regenerate, so when
they become damaged or die, they cannot be replaced.
Parkinson’s disease progresses slowly in most people. Symptoms may
take years to develop and patients may live for years with the disease.
In Parkinson’s disease, the brain stops producing a chemical called
dopamine, a neurotransmitter that helps to convey information from one
neuron to another. As dopamine levels decline, the individual has less
ability to control their movements, body and even their emotions. When
60 to 80 percent of the dopamine-producing cells are damaged, the individual
begins to show symptoms of the disease.
In stage one, symptoms are mild and don’t usually interfere with
daily activities. The individual may have tremors or other movement symptoms,
usually on one side of the body only. Close friends and family may notice
changes in posture, walking and facial expressions.
In stage two, symptoms start to worsen and include tremors, rigidity and
other movement problems on both sides of the body. Difficulty walking
and problems with posture may become obvious. The individual may still
live alone, although activities of daily living may become more difficult
to complete and take longer.
At stage three, new symptoms appear, including loss of balance and slow
movement. Individuals are more inclined to fall. They may continue to
live independently, but symptoms can interfere with ADLs such as dressing
Stage four Parkinson’s symptoms are severe and very limiting. The
person may be able to stand without assistance, but walking with out an
aid is unlikely. The individual needs help with ADLs and is typically
unable to live alone.
Stage five is the most advanced and debilitating stage. Stiffness in the
legs may make it impossible to stand or walk. At stage five, the individual
usually needs a wheelchair or is bedridden. Around-the-clock care is required.
Hallucinations and delusions may be seen.
Individuals may also experience “non-motor” symptoms, including
depression, irritability, problems focusing, slow thinking, memory difficulties,
dementia, sleep disorders, constipation, pain, fatigue, problems seeing
or smelling, weight loss/gain, and difficulty with impulse control.
Like other neurodegenerative diseases, Parkinson’s is incurable.
However, there are medications that can help regulate body movements.
Some of these include Sinemet, Requip, and Miramex. “The goal of
the medications is to increase movement in patients, as well to slow the
disease as much as possible,” said Jessica Slone, APRN. Patients
may also benefit from lifestyle modifications, such as getting more rest
and increasing exercise.
