In a case of suspected Alzheimer's disease, which cognitive deficit is commonly observed?

Agnosia

Aphasia

Executive dysfunction

All of the above

In the context of Alzheimer's disease, all the listed cognitive deficits can be observed, making the selection encompassing various impacts of the disease on cognitive function accurate.

Agnosia refers to the inability to recognize objects, people, or sounds despite the sensory pathways being intact. Individuals with Alzheimer's might struggle with recognizing familiar faces or objects due to the disease's effect on memory and visual processing.

Aphasia, which involves difficulties in language processing, is also prevalent in Alzheimer's patients. This could manifest as trouble finding words, forming sentences, or understanding spoken language. As the disease progresses, these symptoms become more pronounced.

Executive dysfunction is another hallmark of Alzheimer's disease, reflecting difficulties in planning, decision-making, and executing tasks. Patients may find themselves unable to organize their thoughts or actions efficiently, impacting their everyday functioning.

Altogether, these deficits encapsulate the cognitive decline commonly experienced by individuals suffering from Alzheimer's, as the disease affects multiple areas of cognition and daily living. The inclusion of all these deficits in the correct answer underscores the complex and multifaceted nature of cognitive impairment seen in Alzheimer's patients.
