Are there similarities of alzheimer's and parkinson's diseases?

Answer 1

Huntington's disease, also called Huntington's chorea, chorea major, or HD, is an inherited genetic neurological disorder characterized by abnormally uncoordinated, jerky body movements called chorea and a decline in some mental abilities, which can lead to affected aspects of behavior. As the disorder progresses, it can cause complications that significantly reduce life expectancy. Parkinson's disease (also known as Parkinson disease or PD) is a degenerative disorder of the central nervous system that often impairs the sufferer's motor skills and speech, as well as other functions. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia). It is chronic and progressive. It can be primary or secondary to an injury.

Answer 2

Alzheimer's disease is were the gyres of the cerebral cortex separate and deepen. This leads to dementia. Parkinson's disease is a neuromuscular disorder that effects the way muscle contractions are maintained. This usually leads to shakiness.

Answer 3

Both Alzheimer's disease and Parkinson's disease are neurodegenerative diseases, caused by the loss of brain cells; in Parkinson's the dopamine producing cells, and in Alzheimer those associated with intellectual abilities are destroyed. (Alzheimer's disease is a form of Dementia). However, latest research suggests they both share common features: Amyloid plaques or Amyloid fibrils. Amyloid fibrils are suspected to be misfolded proteins. Amyloid plaques are the result of protein fragments' accumulation into a protein deposit on the brain, which is then associated with brain cell destructions. While Beta-amyloid plaques are a feature for Alzheimer's, in Parkinson's sufferers' brain the plaques called Lewy bodies are present. Just for interest, amyloid plaques might also be associated with Type 2 Diabetes, among other diseases.

Answer 4

Age is is the accumulation of changes in an organism or object over time, Alzheimer's is a degenerative disease that is a form of dementia.
