"Every clinical assessment of behavior requires a careful review of frontal lobe functions. Nonetheless, several challenges face behavioral neurologists and neuropsychologists in their clinical attempts to assess the frontal lobes. Whereas an assessment of sensorimotor systems is guided by a relatively well understood pattern of brain-behavior relationships, the frontal lobes are incredibly complex, and because of their extensive interconnections with other neural structures, they control or influence a broad range of behaviors. Injury to the frontal lobes can affect initiation of complex motor behavior, attention, executive functioning, working memory, episodic memory, language, emotions, and behavior."
