Alzheimer's Disease Overview

Alzheimer's disease is the most common cause of severe mental deterioration (dementia) in the elderly. It has been estimated that 30% to 50% of people over 85 years old suffer from this condition. The cause of Alzheimer's is largely not known but many theories have been and continue to be investigated.

Alzheimer’s disease is a chronic, slowly progressive, gradual in onset, irreversible condition that destroys brain nerve cells and other structures in the central nervous system. People with Alzheimer’s disease slowly develop dementia —a loss of memory and intellectual and social skills that result in confusion, disorientation, and the inability to think, reason, and understand. The decline in cognition and memory results in activities of daily living to performed with increasing difficulty.

People with Alzheimer’s disease (and other dementias) can have symptoms that change significantly from day to day, usually getting worse but occasionally seeming to get better. However, people with Alzheimer’s disease do get worse over time, especially regarding memory loss (which is the most common initial symptom).

Common symptoms of Alzheimer's disease include:

  • Difficulty with short term memory (often with maintenance of long term memories)
  • Forgetting recent events and conversations
  • Impaired orientation
  • Misplacing items
  • Poor judgment and insight
  • Loss of interest in hobbies
  • Difficulty with cooking, dressing, shopping, finances
  • Changes in behavior and mood
  • Depression
  • Anxiety
  • Irritability

Scientists know that Alzheimer’s disease is caused by damage to brain nerve cells, as well as a loss of certain chemicals that facilitate communication between nerve cells. What is still not clearly understood is why this damage occurs.

Brain autopsies of Alzheimer's patients show two characteristic brain abnormalities:

  • Neurofibrillary tangles (twisted nerve cell fibers)—These are found inside nerve cells in the hippocampus and temporal and frontal lobes of the brain. A type of protein called tau is found within these tangles.
  • Neuritic plaques—Located outside the nerve cells, the plaques are surrounded by dying neurons (nerve cells) and contain a sticky protein called beta amyloid. It is believed that beta amyloid may cause narrowing of blood vessels in the brain, which in turn plays a role in killing nerve cells. The presence of the plaque seems to be linked to reduction of an important chemical called acetylcholine. Acetylcholine helps neurons relay messages in the brain and is essential for memory and learning.

It has been estimated that over 4 million Americans have Alzheimer’s disease and the total healthcare costs are estimated to be over $100 billion in the US alone. The number of patients with Alzheimer’s disease is expected to triple during the next 20 years as the baby boomer generation ages with an associated rise in the economic burden. In most cases, Alzheimer’s disease develops in people over the age of 65. Although, there is a rare, early-onset form of the disease that may strike people as young as 30. Nearly all people who have Down syndrome develop Alzheimer's disease if they live into their forties.

Alzheimer's Disease and Lyme Disease

Also, there seems to exist a correlation between Lyme disease and Alzheimer's disease, possibly suggesting that the infectious agent responsible for an initial Lyme disease infection could later be implicated as a cause of Alzheimer's disease. (This is speculated after autopsy of some Alzheimer's patients showed a presence of Lyme spirochetes in the brain.)1
