Answer 1

Answer:

B) Alzheimer's disease.

Explanation:

Alzheimer's disease is a neurodegenerative disorder that causes the degeneration and death of brain cells. It is progressive, meaning it occurs gradually over an extended period of time.

Alzheimer's disease occurs when neurons in the brain fail to produce enough neurotransmitters such as acetylcholine which are required for normal communication between neurons in the brain. Acetylcholine plays a vital role in memory retention and recall. Insufficient neurotransmitters causes neurons to begin to die off. This process is known as neurodegeneration.

Neurodegeneration occurs as a result of sticky proteinous lumps that forms hardened layers on the cells in the brain. These abnormal proteins are called beta-amyloid proteins. Also, there are numerous fibres which entangle the nerve cells and are called neurofibrillary tangles.

Alzheimer's disease leads to a gradual decline in thinking, social and behavioural skills and ultimately memory loss and debilitation.
