Answer:
B) Alzheimer's disease
Explanation:
Alzheimer's disease is a neurodegenerative disease characterized by memory loss, mood swings, disorientation and behavioral issues. There are many reasons for the disease as explained by various hypothesis:
- Cholinergenic hypothesis states that decreased production of neurotransmitter acetylcholine causes Azheimer's. Hence many of the current medications target to increase acetylcholine production.
- Tau hypothesis states that the disease is caused by tangling of neurons. This tangling is caused by aggregation of hyperphosphorylated tau protein.
- Amyloid hypothesis states that excess deposits of extracellular beta amyloid protein fragments are responsible for the disease. Amyloid plaques are deposited between the neurons which leads to impaired brain functioning.
