The most noticeable symptoms of Parkinson’s disease are hand tremors. While this may be the most well-known symptom, it is by no means the only visible one. People with Parkinson’s disease display a wide variety of symptoms such as a sense of weakness, difficulty in walking or even constipation.

but firstly you need to learn What is Parkinson's Disease.

Broadly, the symptoms of Parkinson’s can be classified as the following:

Symptoms which involve movement, such as hand tremors and other motor-movement related issues.

Signs that are physical in nature but do not involve any motor functions or movement.

These are cases where it is harder to detect whether the person has Parkinson’s or not because many of the signs may also be due to other factors and issues.

There are many other Parkinson’s causes and symptoms that relate to motor functioning and movement of body parts which indicate towards Parkinson’s disease:

Tremors are shaky movements of the hand caused due to Parkinson’s. The hand trembles, especially when you are lifting a glass or cup of tea.

Gait abnormality is one of the most important factors affecting the quality of life of Parkinson’s patient. Parkinsonian gait is characterized by small shuffling steps and a general slowness of movement called hypokenisa or even the total loss of movement which is called akinesia. In some rare cases, patients also have reduced stride length and walking speed. The patient has difficulty starting, but also has difficulty stopping after starting. This is due to muscle hyper tonicity.

Freezing is like a feeling that the feet are glued to the ground and many people who have Parkinson’s face it. When you freeze, you may not be able to move forward again for some minutes, and you may feel that your feet are stuck to the ground. 

This is prevalent more in the end stage patients where the ability to do everyday tasks such as walking, turning, and standing up or getting up from bed becomes extremely difficult leading to frequent falls.
