• B. b) Alzheimer’s
• C. c) TB
• D. d) Diabetes

Answer 1

The correct option is B

b) Alzheimer’s

Beta-amyloid

• It is also known as amyloid beta — is a sticky protein that can accumulate between brain cells and form “plaques.”
• These plaques disrupt brain cell communication, and this is believed to play a key role in Alzheimer’s disease.

Context

• Scientists from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) discovered that adults who experienced one single night of sleep deprivation showed an immediate increase in levels of beta-amyloid.
• The researchers noticed an increase in beta-amyloid levels in the right hippocampus of the subjects’ brains, as well as in the thalamus.
• The hippocampus is the brain region associated with long-term memory, and the thalamus is a brain region involved in processing sensory information.

Alzheimer’s disease is a progressive cognitive disorder characterized by memory loss and changes in behavior. It is the most common form of dementia, affecting around 5.7 million adults in the United States alone
