Because it’s a progressive degenerative disorder, the condition has defined levels/stages of development based on the number and severity of symptoms. There is no specific test for diagnosing Parkinson’s disease so diagnosis is typically based on the individual’s medical history along with physical and neurological examinations.

Level 1 is the initial phase of the disorder. It is characterized by mild symptoms that generally do not interfere with daily activities. While changes in posture, walking and facial expressions may be noticeable, tremors and other movement issues typically occur on one side of the body.

During Level 2, stiffness, tremors and other movement issues worsen as both side of the body are affected. Individuals with this stage of Parkinson’s can still live alone although some daily tasks and activities may become more difficult or take longer to accomplish.

Level 3 is characterized by slowness of movement and a loss of balance. While an individual can still be fully independent, symptoms may significantly impair some daily activities, such as eating, bathing and dressing.  A level 3 Boxer may benefit from a Corenrman during their boxing workouts.  The primary concerns are safety due to falls and the increased benefit from having individual support and attention.

With the onset of Level 4, the severity of symptoms begin limiting personal independence. Although the person may stand unassisted, movement may require the aid of a walker. Because they will need help with daily tasks, they cannot live alone.  Stage four Boxers require a cornerman while participating in a boxing workout.

The most advanced and disabling level, Level 5 is marked by leg stiffness that makes standing and walking impossible. Sufferers may use a wheelchair or become bedridden. At this stage, daily living requires around-the-clock nursing care. People suffering from advanced Parkinson’s disease may also experience delusions or hallucinations.

In addition to using a rating scale system to determine the stage of disease progression, physicians also evaluate mental functioning, mood and social interaction. While symptoms may vary, knowing the stages can help make plans to anticipate and cope with the changes as they occur.
