Final answer:
Frontal lobe lesions commonly lead to motor impairments, personality changes, and memory loss.
Step-by-step explanation:
Frontal lobe lesions commonly lead to several clinical deficits, including motor impairments, personality changes, and memory loss. Motor impairments can manifest as slowed movements, balance and posture problems, rigid muscles, and speech changes. Personality changes may include disruptions in planning, judgment, reasoning, and working memory. Memory loss can occur due to damage to the structures in the frontal lobe responsible for memory functions.
