Cardiac Output, Venous Return, and Their Regulation
Kiki's project
1. 9d Students know the functions of the nervous
system and the role of neurons in transmitting
electrochemical impulses
9b Students know how the nervous system mediates
communication between different parts of the body
and the body’s interactions with the environment
2. WHAT CAUSES
ALZEIMER’S
Alzheimer's disease start’s by a bunch of proteins in the
brain.
Some how scientist say that plaque’s and tangles may be
the cause of Alzheimer’s.
Alzheimer’s disease occurs when neurons get damaged
in parts of the brain and start to die.
As neurons die, the brain is left with less neuron’s so its
hard to remember new information. So it’s hard to
remember existing memories. As the disease goes on
more neurons die. So they lose their ability to understand
and interact with other people.
3. WHY DOES ALZHEIMER’S
HAPPEN WHEN YOUR OLD
Alzheimer’s disease mostly occurs when someone
reaches an advancing age or somewhere around age
70.
It does it have to be around age 70 it could happen
anytime. Cause of a large amount of the brain’s
neurons are already dead or are dying from the
disease.
The process may accelerate as the person ages. Due
to the brain’s decreasing ability to defend itself
against insults.
4. WHY DO PEOPLE GET
ALZHEIMER’S
People that have parent’s or sibling that developed Alzheimer's
disease are likely to develop it as well.
Scientists say that there’s two kinds of gene that are passed by
family members.. The first gene is APOE-e4, that increases the
chance of developing Alzheimer's. Scientist say there are more
risk genes not discovered.
The second gene is deterministic gene and it’s different than
risk genes. Deterministic genes are only found in a few families.
This gene increases the chances of getting it on a early age.
5. HISTORY OF
ALZHEIMERS
In 1901 a German psychiatrist Alois Alzheimer identified
the first case of what became known as Alzheimer's. A
fifty year old woman he called her Auguste D had
Alzheimer's. she died in 1906 cause of the disease.
It was first described as a distinctive disease by Emil
Kraepelin. For most of the 20th century, the diagnosis of
Alzheimer's disease was reserved for individuals between
the ages of 45 and 65 who developed symptoms of
dementia.
It led to the diagnosis of Alzheimer's disease
independently of age . The term senile dementia which is
(SDAT) was used for those over 65, with low Alzheimer's
disease being used for those younger.
6. WAY’S TO PREVENT
ALZHEIMER’S
You can prevent Alzheimer’s disease and other
dementias by eating right, exercising, staying
mentally and socially active, and keeping stress in
check.
According to scientific research physical exercising
reduces your risk of developing Alzheimer’s disease
by 50 percent.
Also reading can prevent you from having
Alzheimer's.
7. What happens
during it
Neurons begin to work less probably because a abnormal
protein begin to accumulate, forming tangles. Neurons begin to
lose their ability to communicate.
As it progresses and the damage spreads further in the
brain, the person enters a stage referred to as moderate
Alzheimer's disease. The brain continues to shrink and
symptoms become more serious as the disease reaches the
areas of the cerebral cortex that control
language, reasoning, sensory processing, and conscious
thought.
A person with moderate AD may wander or become
confused, anxious or engaging in angry
outbursts, tearfulness, or restlessness. His attention span may
shorten. He may have problems recognizing family and
friends, and difficulty with language, reading, writing and use
of inappropriate undressing or the use of vulgar language.
8. WHY DO SOME PEOPLE GET
ALZHEIMER AND SOME DONT
The first reason why other people just don’t get is
because it does it run on their family. While other’s
do.
Some individuals are able to resist the onset of
Alzheimer’s.
What this people are resilient against is the toxic
buildup in the brain of a fibrous protein called
amyloid. This material is made by cells throughout
the body, throughout one's life, largely to no effect—
until a certain point.
9. SYMPTOMS OF
ALZHEIMERS
The mood and personalities of people with Alzheimer's
can change. They can become
confused, suspicious, depressed, fearful or anxious
A person with Alzheimer's may start to remove
themselves from hobbies such as social activities, work
projects or sports. Or remembering how to complete a
favorite hobby.
People with Alzheimer's may have trouble joining a
conversation. They may stop in the middle of a
conversation and have no idea how to continue or they
may repeat stuff they already said before or start talking
about his past.
10. HOW DO PEOPLE DIE
FROM IT
Alzheimer's patients forget how to eat. Some forget
how to swallow. So when they eat they might start
choking. Or food just goes down the wrong pipe,
Some forget how the breath and they die with out no
one wondering
So typical complications of Alzheimer's are heart
attacks, thromboembolisms, strokes, kidney
failure, and lung infections due to aspiration of food.
11. HOW DOES THIS IMPACT
THE WORLD
Well I think this impacts our community cause many
people die of Alzheimer's. Also it impact their family
and friends. Alzheimer’s is a sad disease because
you for get your family members and don’t
remember the good times you spent with your
friends or family. It’s also a painful death.
