Alzheimer's disease is not accelerated aging

.... With new methods to image amyloid deposition, we can look within the context of how the deposits change structure and function of the brain. Are there antecedent causes? Are some individuals more at risk? Are some areas of the brain more vulnerable and is that why memory is more affected?" ...

Plants will not save us from greenhouse gases
