Detailed explanation-1: -Parkinson’s disease is a progressive disorder that is caused by degeneration of nerve cells in the part of the brain called the substantia nigra, which controls movement. These nerve cells die or become impaired, losing the ability to produce an important chemical called dopamine.

Detailed explanation-2: -Normally, these nerve cells, or neurons, produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems associated with the disease. Scientists still do not know what causes the neurons to die.

Detailed explanation-3: -Parkinson’s disease is caused by a loss of nerve cells in the part of the brain called the substantia nigra. Nerve cells in this part of the brain are responsible for producing a chemical called dopamine.

Detailed explanation-4: -Dopamine deficiency means having a low level of dopamine. Low dopamine levels are linked with certain health conditions like Parkinson’s disease or depression. It may also make you more susceptible to taking risks or developing addictions.
