Parkinson's disease (PD) is also called Paralysis agitans, Shaking palsy. And it’s a type of movement disorder. When nerve cells in the brain can’t produce enough of dopamine (a brain chemical) Parkinson's disease happens. Sometimes it is genetic; however, most cases do not seem to do in families. Other reasons might play an important role in Parkinson's disease. Here are some symptoms of Parkinson's disease.
There are four main types of symptoms of Parkinson's disease: tremor, rigidity bradykinesia and postural instability. These symptoms usually begin gradually and worsen as time passed, except for postural instability, because it is a late symptom. Early symptoms of Parkinson's disease are subtle and occur gradually.
Usually, tremor symptom begins in a hand though sometimes the jaw or one of a foot is affected first. It is pronounced when the hand is at rest or when a person with Parkinson's diseaseis less stressful. For example, when the hands are rested on a table for a few seconds, the shaking may become more obvious after that. Tremor usually disappears during sleep.
Rigidity is a symptom that affects most patients with Parkinson's disease. Movement is possible, because the opposing muscle relaxes, not one muscle becomes more active. The rigidity can become pronounced when another person tries to move the patient’s arm.
Bradykinesia is a particularly frustrating symptom ofParkinson's diseasebecause it may make simple tasks hard. The person cannot quickly perform normal movements. Activities once done quickly and easily— such as washing, writing or dressing — may take many hours.
Postural instability makes people with Parkinson's disease fall easily. Affected people may develop a stooped posture in which the head is bowed and the shoulders are drooped as well.
Many other symptoms may accompany Parkinson's disease. No one can predict which symptoms will affect an individual person as the symptoms vary from person to person.
