Frontal Lobe Functions and Their Impact

While it may seem like an 18, 20, or 22-year-old is capable of making adult decisions, they are not developmentally ready just yet. This is largely due to the fact that the brain's frontal lobe, particularly the prefrontal cortex, which is crucial for impulse control and decision making, isn't fully mature until around age 25.

Coordinating voluntary movements involves effective decision making and impulse control.

Coordinating voluntary movements involves effective decision making and impulse control. This includes assessing similarities and differences between two objects, forming and retaining long-term memories, and understanding language, linguistic memories, and speaking. Additionally, emotional regulation and expression, personality development, and attention regulation play crucial roles in these processes.

Injuries to the Frontal Lobe May Cause

Inability to engage in decision making or poor decision-making skills can lead to difficulties with planning, executive functioning, and attention. This may also result in loss of memory, sudden or dramatic changes in personality, and fluctuations in emotions. Additionally, individuals may experience difficulty understanding social cues a

Inability to engage in decision making or poor decision-making skills can lead to difficulties with planning, executive functioning, and attention. This may also result in loss of memory, sudden or dramatic changes in personality, and fluctuations in emotions. Additionally, individuals may experience difficulty understanding social cues and exhibit issues with empathy or relating to others' emotions. Changes in motor skills and spatial reasoning abilities can further complicate impulse control.

Damage to the frontal lobes significantly impacts decision making and impulse control, as these brain regions are responsible for regulating the ability to control impulses, reason, and make socially responsible judgments. Consequently, such damage can lead to violent and aggressive behavior.
