- - - - primarily affects memory
      - impaired cognition
      - social interactions,
      - ability to perform daily tasks
    - - not natural in ageing !
    - - Cerebrum
      - Brain stem & Cerebellum
        
        Controls basic lives functioning
      - Temporal lobe
        
        difficulties with language
      - Occipital lobe
        
        Problems with vision
    - - Loss of nerve cells in the brains
        
        When many nerve cells, it cannot be replaced hence the brain starts to shrink
    - - Well-being of the Singapore Elderly (WiSE) Study 2015
        
        1 in 10 (10%) aged 60 years and above has dementia
        
        Higher than countries like China and India with a prevalence rate of 8%

  - - - primarily impacts a
        person's attention,
      - can be resolved within a few days or weeks
- - - - during AD amyloids accumulates on the outside of nerve cells forming plagues
    - - important part of the cell network, helping to transport nutrients around the cells
        
        during AD, an abnormal version of Tau is produced, it does not function correctly as it forms tangles inside the cells disrupting the transport network and effectively strangling the cell.
