Parkinson also known as idiopathic Parkinson basically targets dopamine in brain nerve cells specially in mid brain and substantia nigra causes cell death. In Parkinson disorder levels of dopamine are decreased in brain. In early stage of Parkinson signs are very oblivious which includes tremors (shaking of hands), muscle rigidity and slowness of movement.
Treatment can relief the symptoms but do not cure the disease.
