    Recent studies have shown that other species besides humans experience jealousy. Psychology professor Christine Harris designed a study to try to understand the emotion in infants by using dogs. She concluded that jealousy has a basic form that can be found in human infants and other social species.

Alzheimer's Basics

shared by Nicholas Scholz on 11 Aug 13 - Cached
  • Alzheimer's is a type of dementia that causes problems with memory, thinking and behavior.
  • Alzheimer's disease accounts for 50 to 80 percent of dementia cases.
  • Up to 5 percent of people with the disease have early onset Alzheimer's
  • ...8 more annotations...
  • Those with Alzheimer's live an average of eight years after their symptoms become noticeable
  • However, serious memory loss, confusion and other major changes in the way our minds work may be a sign that brain cells are failing.
  • Each nerve cell connects with many others to form communication networks
  • Keeping everything running requires coordination as well as large amounts of fuel and oxygen
  • Plaques are deposits of a protein fragment called beta-amyloid (BAY-tuh AM-uh-loyd) that build up in the spaces between nerve cells.
  • Tangles are twisted fibers of another protein called tau (rhymes with “wow”) that build up inside cells.
  • It's the destruction and death of nerve cells that causes memory failure, personality changes, problems carrying out daily activities and other symptoms of Alzheimer'
  • Ninety percent of what we know about Alzheimer's has been discovered in the last 15 years

    Alzheimer's is actually a common form of dementia. Roughly 50-80 percent of patients with dementia are associated with Alzheimer's. Alzheimer's is considered a neurological disorder with loss of memory, thinking and behavioral function. Alzheimer's is common diagnosed in patients 65 and older with the exception of patients with Early-Onset Alzheimer's. Alzheimer's progressively worsens over time and commonly culminates in death 8 years after symptoms start to arrive. Again no cure has been found for alzheimer's, but certain medications are used to treat symptoms. A build-up of plaques and tangles in the brain is suspected to kill nerve cells and cause a loss of brain function. The loss of nerve cells causes gaps in the communication network and eventually causes a loss of function in those areas of the brain. Although scientists do not know their exact role in Alzheimer's, patients have been associated with an abundant amount of these abnormal structures.

MS Basics

shared by Nicholas Scholz on 11 Aug 13 - No Cached
  • Multiple sclerosis (or MS) is a chronic, often disabling disease that attacks the central nervous system (CNS)
  • MS is a disease that involves an immune system attack against the central nervous system (brain, spinal cord, and optic nerves)
  • Although MS is thought by some scientists to be an autoimmine disease, others disagree strongly because the specific target of the immune attack in MS has not yet been identified. For this reason, MS is referred to as an immune-mediated disease.
  • ...11 more annotations...
  • As part of the immune attack on the central nervous system, myelin (the fatty substance that surrounds and protects the nerve fibers in the central nervous system) is damaged, as well as the nerve fibers themselves
  • The damaged myelin forms scar tissue (sclerosis
  • Relapsing-Remitting MS
  • People with this type of MS experience clearly defined attacks of worsening neurologic function. These attacks—which are called relapses, flare-ups, or exacerbations —are followed by partial or complete recovery periods (remissions
  • Primary-Progressive MS
  • This disease course is characterized by slowly worsening neurologic function from the beginning—with no distinct relapses or remissions
  • Secondary-Progressive MS
  • Following an initial period of relapsing-remitting MS, many people develop a secondary-progressive disease course in which the disease worsens more steadily, with or without occasional flare-ups, minor recoveries (remissions), or plateaus
  • Progressive-Relapsing MS
  • In this relatively rare course of MS (5%), people experience steadily worsening disease from the beginning, but with clear attacks of worsening neurologic function along the way
  • but the disease continues to progress without remissions.

    Multiple sclerosis has been associated with attacks against the central nervous system. The immune system has been identified to targeting organs such as the brain, spinal cord, and optic nerves. It is known as an immune - mediated disease because there is no specific target that has been identified. The attacks by the immune system often damage myelin and create scarred tissue (sclerosis). Patients with multiple sclerosis could experience one of four courses identified with the disease. One course is the Relapsing-Remitting MS. In this course the patient experiences a severe attack on the CNS followed by remissions. The second course is known as the Primary-Progressive MS. In this course the central nervous system slowly deteriorates without any relapses or remissions. Another course of MS is the Secondary-Progressive MS. This form of MS generally follows the relapsing-remitting form of MS and progressively worsens the CNS with or without remissions and plateaus. The most rare form of MS is perhaps the Progressive-Relapsing MS. In this course of MS, patients generally experience a progressive worsening of neurological function, without any remissions.
