MCQ MAHE 2000 Physiology Answer 14

The higher functions are affected.

• Short term memory is impaired with easy distraction.
• Convergent thinking is when there is one correct answer and divergent when there are multiple correct answers. Frontal lobe damage impairs divergent thinking.
• Loss of spontaneous behaviour, like speaking and verbal fluency, impaired drawing and doodling, with general lethargy and initiation of daily routines.
• Impaired strategy formation and planning, especially in unfamiliar situations,
• There is inappropriate behaviour with difficulty using social cues and information to direct, control, or change personal behaviour.
• Inhibition impaired. This leads to perseveration (continuing to attempt a task that is obviously failing). They may confabulate.
• Behavioural changes include breaking rules and taking risks, not following task instructions and gambling. (Gambling involves assessing risk and outcome).
• Social and sexual behaviour inappropriate or altered from previously. In social reasoning the left lobe is more important than the right
• Pseudodepression with psychomotor retardation, while the indifference is like "la belle indifference" of hysteria.
• Pseudopsychopathy (because of the lack of social inhibitions)
• Humour seems to decline with age but is more marked in frontal lobe lesions
