Explanation:
Parkinson's disease: Parkinson's disorder is defined as a nervous system disorder that hinders the movement of an individual.
Symptoms of Parkinson's disorder start moderately, and formerly starts with a barely noticeable tremor in one hand of an individual. Parkinson's disorder tremors are the most common and cause slowing movement or stiffness.
Parkinson's disease arises when a neuron or nerve cells, in the area of the brain that is responsible for controlling movement becomes impaired. These neurons are responsible for producing dopamine which is an important brain chemical.
After processing information, long-term memories/important information are stored throughout the brain as groups of neurons that are primed to fire together in the same pattern that created the original experience, and each component of a memory is stored in the brain area that initiated it.
