Changes in a person's behaviour can be a sign of damage to the brain. Below are descriptions of each area of the brain, its function and how damage can cause specific changes.
- Affected early in Alzheimer's disease
- Involved with memory and emotion
- Links the lobes of the brain, enabling them to connect behaviour with memories
- Controls emotion and basic needs, such as sleeping and eating
Hippocampus and temporal lobes:
- The hippocampus processes verbal and visual memory. Verbal memories relate to what we read, say or hear; visual memory lets us recognize objects, faces and places to guide us around our environment.
- Temporal lobes control new learning and short-term memory.
- Help us sequence actions, such as getting dressed in the right order or starting and driving a car
- Control our ability to understand spatial information, such as our location in a specific environment and where other objects are
- Initiates activity and lets us plan and organize our actions
- Regulates social judgment and behavior, such as knowing appropriate behaviour for a situation, interpreting others feelings and monitoring our actions
- Controls vision and the ability to see and combine colours, shapes, angles and movement into meaningful patterns
