What Are The Different Stages Of Parkinson's?

Feb 15, 2024 By Madison Evans

The progression of Parkinson's disease may be estimated by looking at its various phases. Although resting tremors, stiffness, and slow movement are common signs of the condition, no two instances are comparable. In the early stages of Parkinson's disease, a person may only suffer moderate symptoms that do not significantly hinder everyday life. Over time, persons with Parkinson's disease may acquire significant mobility problems that make it difficult to stand or walk. While there's no predicting what each individual's Parkinson's disease stages timeline may look like.

Parkinson's Disease Has Five Phases.

Parkinson's disease is classified into phases using the Hoehn and Yahr scale, which considers the onset and progression of symptoms. Initially, there were five levels; however, the scale has since been adjusted to include stages 1.5 and 2.5.

Stage 1:

In the initial stage, patients often experience modest symptoms that don't interfere with day-to-day activities. In this first phase, symptoms are often localized to one side of the body (also known as unilateral involvement). Symptoms include tremors and other movement issues, as well as changes in posture, walking, and facial expressions. Parkinson's disease is notoriously difficult to diagnose at this early stage due to the relative mildness of the symptoms.

Stage 1.5

The only real distinction between this and the previous stage is that the neck and spine are now being affected.

Stage 2

Bilateral (affecting both sides of the body) symptomatology is characteristic of late-stage Parkinson's disease. However, this stage does not affect balance. It may take months or years to advance from the first step to the second one. Changes in posture and your walk are now more obvious. You may start slurring your words and losing control of the tone of your voice. In this stage, you might also expect to experience increased rigidity and a lack of control over your facial expressions. Each of these symptoms will hinder your daily life in some way, even if just a little.

Stage 2.5

There is still no loss of balance at this level, although you may notice a little impairment. The "pull test" is frequently conducted to evaluate the degree to which your balance has been impacted. In this exam, a healthcare professional will stand behind you and gently pull you back while you try to keep your balance.

Stage 3

The third stage of Parkinson's disease is a substantial advancement of the illness and is frequently believed to be the midpoint of the disease's progression. Eventually, dizziness sets in, prompting a check through the pull test. Patients are considered to have impaired balance if they lose their footing and need to be caught by a healthcare practitioner to avoid a fall. In the third phase, bradykinesia sets in and you experience a noticeable slowing of your body's motions. At this point, your healthcare professional should be able to establish a firm diagnosis of Parkinson's disease. At this point, your disability is more obvious, and you may have a harder time getting dressed or eating.

Stage 4

At this point, your symptoms have reached a crisis point. Daily activities become impossible to do without help, and even if you can do so, you will find that doing so is very difficult. Your body parts and the slowness of movement grow much worse. Standing and walking alone is still an option. However, it may be challenging, and a walker may be helpful.

Stage 5

Most (if not all) of the Parkinson's symptoms you've been experiencing will increase, making this the most severe stage of the illness. It becomes hard for you to walk about unassisted, and a wheelchair is essential. You won't be able to care for yourself in the most basic ways. As a result, continuous nursing care is required to forestall the occurrence of falls and other incidents. Delusions, dementia, hallucinations, and general mental disorientation may also occur at this point in the disease process. It's crucial to remember that everyone with Parkinson's disease has a unique experience with the illness and its symptoms. Medically.


Movement is impaired by Parkinson's disease, a degenerative disorder of the neurological system. Not everyone with Parkinson's would have every symptom, and the disease's variability means that symptoms may vary in both kind and intensity from individual to individual. Patients with Parkinson's disease progress at varying rates. Although not all people with Parkinson's will suffer the same progression of symptoms or the same severity of those symptoms, doctors have identified phases that reflect the course of the illness. There are, however, common patterns of development in Parkinson's disease. Medical experts use these five phases of Parkinson's across the globe to categorize patients and may assist persons who have Parkinson's in dealing with changes as they occur.
