Is Parkinsons Disease a muscular disease?
No. It is a neurologic disease, originating in the dopaminergic pathways of the brain, including the substantia nigra, caudate and putamen, as well as other structures.
What happens when the substantia nigra is damaged?
Degeneration of neurons especially in substantia nigra of both sides might cause Parkinson's disease.
Why is parkinsons treated with dopamine?
The symptoms in Parkinson's Disease are due to not enough dopamine at a particular part of the brain, specifically the substantia nigra. So the goal in treatment is to try and replace this missing dopamine.
What disease results from a degeneration of dopamine-released neurons of the substantia nigra?
these two structures take part in complex control loops that govern certain aspects of movement and, when substantia nigra cells degenerate, these loops are disrupted and movements become unregulated, producing the symptoms of Parkinson's disease.
What is dopamine secreted by?
substantia nigra
Where is substantia nigra located?
The substantia nigra are located in an area of the brain around the lateral ventricles known as the basal ganglia. This is an addition to the above-mentioned answer. To be more specific, substantia nigra lies in the midbrain, dorsal to the cerebral peduncles.
Name the disease which is a result of decreased dopamine levels?
Parkinson's, depression, anxiety. Destruction of substantia nigra in the basal ganglia leads to movement disorders, lack of the dopamine in the limbic system leads to emotional disturbances such as depression, anxiety, some roles in schitophrenia, etc.
Why do people get parkinsons disease?
It is a degeneration of dopaminerge neurons in substantia nigra in the brain, which results in less excitatory and inhibitory dopamine to the basal ganglia. The reasons for the degeneration of neurons is yet unknown. It usually begins at the age of 40. Parkinson's sometimes runs in families, a
What is the cause of Parkinsons?
Parkinson Disease is a gradual neurodegenerative disorder caused by motor deficits which is due to dopaminergic neurons loss in the substantia nigra and the production of lewy bodies. In this case the facial muscles are affected including upper and lower extremities and this also leads to a condition name parkinsonism.

What is the relation between substantia nigra and alzheimer's disease?
The substantia nigra is best known for its production of dopamine, a major neurotransimitter used in certain cell populations in the brain. The most common link with respects to pathology, is in Parkinson's disease, where these cell populations (in the substantia nigra) die off, and the brain has very low amounts of dopamine to work with. Sorry I couldn't be more specific to the alzheimer's respects, but I'm just giving what I know. Take care.
Does Parkinson's disease affect the brain stem?
No, parkinson's affects the dopaminergic neurons of the substantia nigra, which is part of the mid-brain.
The brain structure that produces dopamine?
substantia nigra
