The Correct Answer is D
Alzheimer disease is a progressive neurodegenerative disorder that affects memory, cognition, behavior, and daily functioning. Alzheimer disease is characterized by the accumulation of amyloid-beta plaques and neurofibrillary tangles in the brain, which impair the communication and survival of neurons. Alzheimer disease is influenced by genetic and environmental factors, and some rare forms of the disease are caused by mutations in specific genes.

Correct Answer is B
Explanation
A. Hyperglycemia: Hyperglycemia is characteristic of diabetes mellitus, not diabetes insipidus. Diabetes insipidus involves an issue with antidiuretic hormone (ADH) and water balance, not glucose regulation.
B. Polydipsia: This is a hallmark symptom of diabetes insipidus. It refers to excessive thirst due to the body’s inability to retain water, leading to dehydration and compensatory increased fluid intake.
C. Weight gain: Weight gain is not typically associated with diabetes insipidus. The condition usually leads to weight loss due to fluid loss.
D. Oliguria: Oliguria (reduced urine output) is the opposite of what occurs in diabetes insipidus. The condition is characterized by polyuria, or excessive urination, due to the kidneys' inability to concentrate urine.
