Biological Causes

• 1. Abnormal Build up of Beta-Amyloid

  forms plaque in between synapse of neurons, interfering with neural connections
• 2. Cell Death

  • protein build-up, low connections and causes Neurofibrillary Tangles; tendency to cell death
• 3. Lack of Acetylcholine

  • A memory neurotransmitter. Alzheimer's destroys the neurons that produce the neurotransmitter
• 4. Brain Atrophy

  • occurs when neurons die, due to amyloid plaques and Neurofibrillary Tangles increasing, causes brain tissue to shrink and cause Brain Atrophy
