CParkinson's disease
DNone of the above
Correct answer: (A) Alzheimer's disease — The disorder that slowly destroys memory and thinking is Alzheimer's disease, so that is the answer.
Explanation
★The disorder that slowly destroys memory and thinking is Alzheimer's disease, so that is the answer.
★Alzheimer's is an irreversible, progressive brain disorder in which mental abilities decline steadily.
★It first erodes memory and thinking and in time removes even the ability to do the simplest daily tasks.
★Dyslexia is a learning disorder affecting reading, not a progressive destruction of memory.
★Parkinson's disease is a movement disorder marked by tremor and stiffness, not mainly a loss of memory.
★Since only Alzheimer's fits this steady loss of memory and thinking, the other choices do not apply.
