Parkinson's disease symptoms
Parkinson's disease symptoms

The primary symptoms of Parkinson's disease are related to voluntary and involuntary motor function that usually start on one side of the body. Symptoms are mild at first and may progress over time. Some motor functions affected during parkinson's disease include tremors, rigidity, bradykinesia, postural instability and parkinsonian gait.

Dopamine levels and Parkinson's disease
Dopamine levels and Parkinson's disease

Parkinson's disease develops due to death of cells located in the substantia nigra part of the brain. These cells produce dopamine and the loss of dopamine in the brain leads to movement diffliculty.

Effects of parkinson's disease
Effects of parkinson's disease

Parkinson's disease leads to uncontrolled body tremors due to lack of dopamine in the neuronal cells.

Parkinson's disease involves neurodegeneration in certain regions of the brain. Scientists have identified certain drugs to treat such kind of damage.

The substantia nigra is a melanin-containing nucleus in the ventral midbrain. It consists of dopaminergic neurons, which produce large amount of dopamine during  parkinson's disease.

Parkinson's disease is a brain disorder, which affects various body organs. You may observe various signs and symptoms of parkinson's disease in different parts of your body such as your lungs, muscles, intestine, skin and sensory organs.

Parkinson's produces various symptoms such as hand tremors, weight loss, indistinct speech, constipation and many more.

Substantia nigra decreasees in its volume in a Parkinson's patient. There is degeneration of dopaminergic neurons in the pars compacta of the substantia nigra region in the brain.
