PS124: Introduction to Psychology June 30, 2014 The disorder of the brain that I am interested in is a stroke. Stroke affects more than just the brain as well. A stroke occurs when blood flow to part of the brain is suddenly interrupted or when blood vessel in the brain bursts. Brain cells need oxygen and they die when they no longer receive oxygen and nutrients from blood. When your brain cells die from a stroke, abilities controlled by that area of the brain are lost.
UNIT 4222-365 1.1 Range of causes of dementia Cells in the brain stop working, and the part of the brain that this occurs in will affect how that person thinks, remembers and communicates. The most common forms of dementia are Alzheimer’s disease and Vascular dementia. Alzheimer’s disease is caused by damage in certain areas of the brain. With time, it spreads and affects cells in other parts of the brain. The cause of the brain cells dying and the deterioration of the connectors is not fully known.
A person’s own immune system attacks the myelin sheath that surrounds the axon of the nerves. Once the myelin sheath is damaged, the nerves cannot transmit signals properly. Nerve damage leads to muscle weakness, loss of reflexes, and numbing or tingling of the hands and feet. This is caused by the muscles loss of ability to respond to the brains commands. GBS is not often fatal but in rare cases people have died from GBS.
You must be immunized within one week to four months prior to exposure for the vaccine to be effective. The vaccine is composed of inactivated organisms from several virus strains with scientist attempt to include the most recent mutation. Vaccines are typically 67-92 percent effective. Although most people recover fully from the flu, some develop serious complications, including life threatening conditions such as pneumonia. About 20,000 people in the United States die from flu complications each year and thousands more need to be hospitalized prior to recovery.
Outcome 1 Know what a stroke is 1.1 Identify the changes in the brain associated with stroke Heart attacks and strokes are usually due to cardiovascular disease, a condition featuring body-wide damage to the delicate lining of the arteries the tubes that carry oxygen and nutrient-rich blood to all the organs, tissues and cells in your body and to the brain. The psychological, behavioural and emotional changes that take place after a stroke are part caused by physical damage to the brain. When the brain cells are damaged the sensations and parts of the body controlled by the cells can no longer function properly. This usually affects the left hand side of the body. But I personally have seen someone who has had a stroke and it has
The chemical and electrical signals are necessary in controlling bodily functions – for example language, decision-making, memory, personality, behaviour, sensing and interpreting our environment, and controlling muscle movements. If the neurons and synapsed of the brain become damaged by dementia they may have difficulty or be unable to carry the messages that tell the section of the brain what to do. Depending on the area of the brain affected, this can result in changes to the way the individual thinks, or may result in physical impairments, personally and behaviour changes or the inability to perform certain functions. Area of the brain | Key functions that could be affect by dementia | Frontal lobe | Movement, emotional behaviour, personality, interpretation and feeling. | Parietal lobe | Language, special awareness and recognition | Temporal lobe | Long – term memory, speech and hearing | Occipital lobe | Vision | Cerebellum | Balance, posture, muscle coordination (movement) | Hypothalamus | Regulates thirst, appetite, body temperature and also
CF-like disease has been known for over two centuries. The name, cystic fibrosis of the pancreas, was first applied to the disease in 1938. How Common Is CF? According to the data collected by the Cystic Fibrosis Foundation, there are about 30,000 Americans, 3,000
Rheumatoid arthritis is also a systemic disease, involving other body organs, whereas osteoarthritis is limited to the joints. Over time, both forms of arthritis can be crippling. The affect of rheumatoid arthritis can progress to the degree that it is crippling. Deformities distinctive to late-stage rheumatoid arthritis such as ulnar deviation of the bones of the hands, or swan-neck deviation of the fingers occur because muscles and tendons on one side of the joint may overpower those on the other side, pulling the bones out of alignment. Symptoms Symptoms can range from mild to severe.
Vascular dementia- Vascular dementia is caused by the flow of blood and oxygen to the brain being interrupted causing the death of brains cells, this is called an infarct. Vascular dementia could be caused by a single event such as a stroke, which is known as a single infarct dementia or it could be caused by a series of small events (mini-strokes) over time, known as multiple infarct
MS research paper http://www.nationalmssociety.org/index.aspx what is MS? Multiple sclerosis (or MS) is a chronic, often disabling disease that attacks the central nervous system (CNS), which is made up of the brain, spinal cord, and optic nerves. Symptoms may be mild, such as numbness in the limbs, or severe, such as paralysis or loss of vision. The progress, severity, and specific symptoms of MS are unpredictable and vary from one person to another. Today, new treatments and advances in research are giving new hope to people affected by the disease.
