A nurse is educating the family of a client who has Alzheimer's disease. The nurse should be sure to communicate that which of the following behavioral manifestations can occur in clients with Alzheimer’s disease? (Select All that Apply.)

A. Tau protein: Tau protein is primarily associated with Alzheimer's disease and other tauopathies, not Lewy body dementia.

B. Neurofibrillary tangles: Neurofibrillary tangles are aggregates of hyperphosphorylated tau protein found in Alzheimer's disease, not typically in Lewy body dementia.

C. Alpha-synuclein protein: Lewy bodies, which are abnormal aggregates of alpha-synuclein protein, are a hallmark pathology of Lewy body dementia. These protein aggregates disrupt neuronal function and are responsible for the cognitive, motor, and emotional symptoms seen in Lewy body dementia.

D. Beta-amyloid protein: Beta-amyloid protein is primarily associated with Alzheimer's disease, not Lewy body dementia. It forms plaques in the brain, which contribute to neurodegeneration and cognitive decline in Alzheimer's disease.

A. Rheumatoid arthritis: Rheumatoid arthritis is an autoimmune condition characterized by chronic inflammation of the joints. Some research suggests a possible link between autoimmune disorders such as rheumatoid arthritis and Meniere's disease. Autoimmune conditions can affect the inner ear, leading to vestibular dysfunction and contributing to the development of Meniere's disease.

B. Bacterial pneumonia: Bacterial pneumonia is a respiratory infection caused by bacterial pathogens. There is no direct association between bacterial pneumonia and an increased risk of developing Meniere's disease. Meniere's disease primarily affects the inner ear and is not related to respiratory infections.

C. Macular degeneration: Macular degeneration is a degenerative eye disease that affects the central portion of the retina. There is no known association between macular degeneration and an increased risk of developing Meniere's disease. These conditions affect different parts of the body and are not related in terms of etiology or risk factors.

D. Osteoporosis: Osteoporosis is a condition characterized by loss of bone density, leading to an increased risk of fractures. There is no direct association between osteoporosis and an increased risk of developing Meniere's disease. These conditions affect different systems in the body and are not known to be related.
