What Changes in the Brain?

Brain Changes in Dementia
In a healthy brain, nerve cells (neurons) constantly communicate with each other. In dementia, these communication networks break down.
Key Changes
- Protein buildup: Amyloid plaques and tau tangles accumulate between brain cells
- Neuronal loss: Nerve cells die and cannot be replaced
- Synaptic disruption: Cell-to-cell communication becomes difficult
- Brain volume reduction: Especially the hippocampus (memory center) shrinks
Affected Regions
| Brain Region | Function | Dementia Impact |
|---|---|---|
| Hippocampus | Memory formation | Difficulty learning new information |
| Temporal lobe | Language & understanding | Word-finding difficulty |
| Frontal lobe | Planning & decisions | Organizational problems |
| Parietal lobe | Spatial awareness | Navigation difficulty |
