What is Parkinson's disease and what are the symptoms?

Loss of dopamine. Gradual loss of Dopamine cells in the brain and specifically an area called substantial nigra leads to a group of clinical symptoms and signs: tremor at rest, slow movements, rigid muscles, gait shuffling, lack of facial expression, small handwriting etc. Read more...

What distinguishes Parkinson's disease from alzheimer's disease?

Many things. Parkinson's Disease will present with physical symptoms such as shakiness, stiffness of the limbs causing a shuffling gait, lack of facial expression causing a mask-like face and the dementia may occur later while Alzheimer's dementia starts with gradual memory problems which begin to get worse in a few years and maybe accompanied with paranoid delusions.

Further Detail. Polymers of a-synuclein protein form into "clumps" (intraneuronal inclusions) due to faulty "trash removal" processes in the neurons. As a result, cellular activity is disrupted. Other problems, such as oxidative stress causing mitochondria damage (energy producing portion of cell) lead to programmed cell death, or "apoptosis." many other facets of this cascade of problems are yet to be understood.

Please explain what does Parkinson's disease do to the body?

Parkinsons symptoms. Parkinsons disease, when not treated, tends to cause slowing of movements, as if movement is inhibited. This can affect writing, buttoning, or speaking for example. Muscle tone may be increased with passive manipulation. People sometimes feel "frozen" when walking or lying in bed. Many people with Parkinsons have a tremor when the arms are at rest. This ceases with movement however. Read more...

Neurologic disorder. Parkinson's disease is degenerative disorder of the central nervous system.Motor symptoms of parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain. Cause of cell death is unknown. Shaking, rigidity, slowness of movement, difficulty in walking and gait, later, thinking and behavioral problems arise, advanced disease dementia. Read more...
Loss of neurons. Many issues still not understood but main feature is a progressive loss/lack of replacement of neurons in a portion of the mid-brain called the substantia nigra. Like most degenerative diseases, it usually progresses for decades before symptoms become apparent: shaking, rigidity, slowness of movement & difficulty with walking; altered stooped & slow gait.
