What is Parkinsonism disease?

Answer 1

Parkinson's disease is a chronic progressive nervous disease chiefly of later life marked by tremor and weakness of resting muscles and by a shuffling gait. A disorder of the brain, it can result in difficulty with walking, movement, and coordination.
From answers.com: Parkinson's disease (PD) is a progressive movement disorder marked by tremors, rigidity, slow movements (bradykinesia), and posture instability. It occurs when cells in one of the movement-control centers of the brain begin to die for unknown reasons. PD was first noted by British physician James Parkinson in the early 1800s.

Answer 2

Parkinson’s occurs when certain nerve cells (neurons) in a part of the brain called the substantia nigra die or become impaired. Normally, these cells produce a vital chemical known as dopamine. Dopamine allows smooth, coordinated function of the body's muscles and movement. When approximately 70% of the dopamine-producing cells are damaged, the symptoms of Parkinson disease appear

Parkinson's disease is a progressively degenerative neurological disorder which affects the control of body movements.

Symptoms:

The presentation of symptoms varies greatly between individuals diagnosed and no two people will be affected in the same way. The three symptoms used for diagnostic purposes are:

1. Tremor, (shaking, trembling) is the most well known symptom of PD, but is absent in one third of people when the condition is first diagnosed. Tremor usually begins in one hand and the spreads to the leg, before crossing to the other side. It may also be felt internally. Typically it is most noticeable at rest and when stressed or tired and disappears during movement and when asleep.
   
   
2. Rigidity or stiffness of the muscles is a very common early sign of PD whereby the muscles seem unable to relax and are tight, even at rest. You might feel that your muscles will not do what you want them to do. Rigidity may be experienced through the entire range of movement of a joint (called 'lead pipe rigidity') or just in parts (called 'cog-wheel rigidity).
   
   
3. Bradykinesia (slowness of movement) occurs because the brain is not able to control smooth and delicate movements.
   
   
   • Leads to a lack of spontaneous activity eg. arm swing diminishes.
   • Fine motor coordination is reduced eg. handwriting becomes smaller.
   • May lead to freezing or periods of immobility.

Answer 4

Parkinson's disease (also known as Parkinson disease or PD) is a degenerative disease of the brain (central nervous system) that often impairs motor skills, speech, and other functions.[1] Parkinson's disease belongs to a group of conditions called movement disorders. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia). The primary symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine, which is produced in the dopaminergic neurons of the brain. Secondary symptoms may include high level cognitive dysfunction and subtle language problems. PD is both chronic and progressive.

PD is the most common cause of chronic progressive Parkinsonism, a term which refers to the syndrome of tremor, rigidity, bradykinesia and postural instability. PD is also called "primary parkinsonism" or "idiopathic PD" (classically meaning having no known cause although many genetic mutations associated with PD have since been discovered). While many forms of parkinsonism are "idiopathic", "secondary" cases may result from toxicity most notably of drugs, head trauma, or other medical disorders. The disease is named after English physician James Parkinson, who made a detailed description of the disease in his essay: "An Essay on the Shaking Palsy" (1817).adykinesia and postural instability.
