Transcript of Huntington's Disease vs. Parkinson's Disease

Huntington's Disease vs. Parkinson's Disease
Huntington's Disease
Definition:
Huntington's disease usually causes movement, cognitive (the mental processes of perception, memory, judgement, and reasoning) and psychiatric disorders with a wide spectrum of signs and symptoms.

Huntington's Disease (Cont.)
Symptoms:
Which symptoms appear first varies largely among the affected people. During the course of the disease, some symptoms appear to be more dominant and have a greater affect on the person.
Some symptoms include:
Mood Swings
Depression
Affect Memory, Judgement, and Cognitive Functions
Make Simple Tasks Difficult
Problems With Balance
Jerking Movements
Parkinson's Disease (Cont.)
Symptoms:
The symptoms of Parkinson's Disease start to affect only one side of the body. Some individuals are affected more by the disease than others.
Some of the symptoms include:
Tremors in fingers, hands, arms, feet, legs, jaw, or head.
Stiffness of the limbs
Slowing of voluntary movements
Bad posture
A shuffling walk with a stooped position and an absent arm swing
Parkinson's Disease
Definition:
Parkinson's disease is a progressive disorder of the nervous system that affects your movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. Parkinson's also tends to affect men 1.5-2% more than women.
Conclusion
Although Huntington's and Parkinson's Disease have different causes, they have similar symptoms. Both diseases are threatening and have many scientists scratching their heads. With no known cures, HD and PD are a large threat to everyone.
Huntington's Disease (Cont.)
What is Being Done to Help:
Now that the gene that causes HD has been found, scientists are researching new ways to help the people affected.
Some of the things they are doing are:
Breeding animals with the gene
Using PET (Positron Emission Tomography) technologies to see how the gene affects other parts of the body
Implanting fetal tissue into rodents and nonhuman primates to help understand the gene better
Parkinson's Disease (Cont.)
What is Being Done to Help:
Although there is no known cure for PD, there are medications that dramatically decrease the symptoms.
There are three categories that the drugs fall into:
Drugs that work directly or indirectly to increase the level of dopamine in the brain
Drugs that affect other neurotransmitters in the body in order to ease some of the symptoms of the disease
Medications that help control the non-motor symptoms of the disease
Medications help decrease how dramatic the symptoms are
Affect parts of the brain
Affect how a person acts and/or moves
No known cure
Affect your nervous sys
Affects males and females equally
Can happen to young children
Hereditary disorder
Symptoms vary widely among each person
Affects males at a 1.5-2% higher rate than females
Happens mostly in people over 60
Can happen to anyone, regardless of family history
Primary symptoms affect movement
More common
