Multiple choice

What is “Alzheimer's disease?

  1. It affects liver

  2. It is a disorder of the brain

  3. It affects human immune system

  4. It affects kidney
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Alzheimer's disease is a progressive neurodegenerative disorder that causes brain cells to degenerate and die, leading to memory loss and cognitive decline.

Multiple choice

  1. French polio

  2. Malaria

  3. German measles

  4. Reynolds disease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

French polio is Guillain- Barré syndrome (GBS) causes progressive muscle weakness and paralysis (the complete inability to use a particular muscle or muscle group), which develops over days or up to four weeks, and lasts several weeks or even months.

Multiple choice

A 60-year old woman with recent damage to the hippocampus from a stroke would likely to have all of the following deficits EXCEPT?

  1. difficulty in learning new facts

  2. difficulty in describing a recent event

  3. difficulty in recalling a childhood memory

  4. difficulty in remembering a face

  5. difficulty in learning a new vocabulary
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The hippocampus is involved in the formation of new memories, but not in the storage of old memories after they have been consolidated.

Multiple choice

The deficiency of which of the following vitamins impairs the metabolism of neurotransmitters in the body leading to serious disorders like depression?

  1. Vitamin B6

  2. Vitamin B7

  3. Vitamin B9

  4. Vitamin B12

  5. Vitamin B2
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Low levels of  vitamin B9 can disrupt transmethylation reaction, leading to an accumulation of homocysteine (hyperhomocisteinemia) and to impaired metabolism of neurotransmitters (especially the hydroxylation of dopamine and serotonin from tyrosine and tryptophan), phospholipids, myelin and receptors. All of these can lead to the development of various disorders including depression.

Multiple choice

Which of the following is a chronic inflammatory demyelinating disease that damages the myelin sheath of neurons?

  1. Tourette's syndrome

  2. Multiple sclerosis

  3. Parkinson's disease

  4. Alzheimer's disease

  5. Huntington's disease
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating disease meaning that the myelin sheath of neurons is damaged. Symptoms of MS include visual and sensation problems, muscle weakness and depression.

Multiple choice

What of the following statements is incorrect about Alzheimer’s disease?

  1. It causes plaques and tangles between and within brain cells.

  2. It is a common form of dementia.

  3. One of the symptoms can be out-of-character mood changes, including agitation; less interest, motivation or initiative; apathy; social withdrawal.

  4. It is more common in people who consume salt without iodine.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Like all types of dementia, Alzheimer's is caused by brain cells death. It is a neurodegenerative disease, which means there is progressive brain cells death that happens over a course of time. The total brain size shrinks with Alzheimer's - the tissue has progressively fewer nerve cells and connections. In Alzheimer's, there are microscopic 'plaques' and 'tangles' between and within brain cells. While they cannot be seen or tested in the living brain affected by Alzheimer's disease, postmortem/autopsy will always show tiny inclusions in the nerve tissue, called plaques and tangles. Plaques are found between the dying cells in the brain - from the build-up of a protein called beta-amyloid.

Multiple choice

What condition is a contraindication for microcurrent?

  1. occasional migraines

  2. epilepsy

  3. asthma

  4. bipolar disorder
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Microcurrent therapy uses electrical impulses that can interfere with the electrical signals in the brain, making epilepsy a primary contraindication.

Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

What would happen to the person if cerebellum of his brain is damaged?

  1. He will lose his memory power

  2. He will not be able to swallow food properly

  3. He will be unable to coordinate and stand properly

  4. He will lose his power of vision and hearing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The cerebellum is located down to the occipital lobe of the cerebrum. The cerebellum is the vital part of the brain that controls the motor movements of the body. Its functions include coordinated movement, balance, posture, speech, etc. Thus in this case, if the cerebellum is damaged the person won't be able to stand or walk properly. So, the correct answer is option C.

Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

If cerebellum of man gets damaged, his movement becomes

  1. Shaky and speech becomes defective

  2. Unbalanced walk, uncontrolled and defective speech, intention tremor

  3. Jerky and defective speech

  4. Jerky and walked uncontrolled
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The cerebellum is located down to the occipital lobe of the cerebrum. The cerebellum is the vital part of the brain that controls the motor movements of the body. Its functions include coordinated movement, balance, posture, speech, etc. Thus his movement and speech becomes unbalanced and uncontrolled. Thus, the correct answer is option B.

Alzheimer disease in humans is associated with the deficiency of :

  1. Gamma aminobutyric acid (GABA)

  2. Dopamine

  3. Glutamic acid

  4. Acetylcholine
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alzheimer disease is characterized by the progressive loss of cholinergic neurons in the brain, leading to a significant deficiency in the neurotransmitter acetylcholine, which is crucial for memory and learning.
