Understanding the Different Types of Dementia
As we age, it is normal to lose some neurons in the brain. People living with dementia, however, experience far greater loss. Many neurons stop working, lose connections with other brain cells, and eventually die. At first, symptoms can be mild, but they get worse over time.
Most Common Types:
- Alzheimer's Disease - abnormal deposits of proteins form amyloid plaques and tau tangles throughout the brain.
- Frontotemporal Dementia - abnormal amounts or forms of tau and TDP-43 proteins accumulate inside neurons in the frontal and temporal lobes.
- Lewy Body Dementia - abnormal deposits of the alpha-synuclein protein, called "Lewy bodies," affect the brain's chemical messengers.
- Vascular Dementia - conditions, such as blood clots, disrupt blood flow in the brain.
