Final answer:
Right frontal lesions can cause behavioral and emotional changes, including diminished initiative and expressivity. They may also result in deficits in non-verbal communication and facial expressions, alongside possible cognitive disruptions.
Step-by-step explanation:
Patients with right frontal lesions typically exhibit behavioral and emotional changes due to the role of the frontal lobe in personality and cognitive functions.
Manifestations may include diminished initiative, interest in the environment, and displays of emotion or affect. Neuroleptic drugs can mitigate these symptoms, by reducing agitation and promoting responsiveness, though side effects may include reduced emotional expression and responsiveness to stimuli.
Moreover, the right frontal lobe is associated with non-verbal communication and could lead to deficits in expressing emotions through facial expressions. Lesions in this area may result in a flat affect or reduced facial expressivity.
Additionally, right frontal lobe damage could lead to cognitive disruptions, such as impaired judgment or attention, which in turn impacts the overall demeanor of a patient.
It is important to note that individual presentation may vary, and a comprehensive neurological examination is essential for an accurate diagnosis and proper treatment planning.
