Final answer:
Alzheimer's disease affects multiple brain lobes, including the frontal lobe, which when impaired, can result in difficulty with planning, poor judgment, and personality changes due to its role in cognitive functions and language.
Step-by-step explanation:
Alzheimer's Disease and Brain Lobes
Alzheimer's disease affects several regions of the brain, including the frontal lobe, parietal lobe, and temporal lobe. Each lobe experiences different symptoms due to the progression of the disease. The frontal lobe, for instance, is essential for higher cognitive functions and its impairment can lead to symptoms such as difficulty planning or executing tasks, poor judgment, and personality changes. These symptoms are associated with the damage that occurs to the regions involved in executive functions, such as the prefrontal cortex and areas responsible for language like Broca's area. As Alzheimer's disease progresses, damage to the frontal lobe increases, affecting a person's ability to perform complex tasks, control emotions, and even engage in linguistic expression.
It's important to note that while the occipital lobe is involved in vision, and the temporal lobe in auditory processing, the symptoms listed for Alzheimer's (memory loss and hearing impairment) are typically not associated with these lobes. Instead, the parietal lobe can be directly associated with spatial navigation difficulties, and the temporal lobe with memory loss and issues with language comprehension. However, ultimate diagnosis and understanding of symptoms require professional medical evaluation.
