Dementia is one of the most dreaded human conditions, both by those observing it and by those experiencing it. It is defined as a persistent and progressive impairment of intellectual function, and can affect memory, emotions, personality, language, judgment, and cognition. It is frequently associated with other medical conditions, including Alzheimer’s disease, stroke, and spongiform encephalopathies.

Encephalopathies are diseases of the brain. The spongiform encephalopathies are named for their characteristic deterioration of central nervous system tissue, resulting in a sponge-like appearance of the brain. They include kuru, Creutzfeldt-Jacob disease (CJD), Gerstmann-Straussler-Scheinker (GSS) disease, and familial fatal insomnia (FFI). Unlike Alzheimer’s disease and strokes, the spongiform encephalopathies can be transmissible. Transmission of dementia was originally thought to be due to a virus; however, subsequent information suggests that the agent of transmission is simply a protein, with no associated nucleic acid. These proteins were termed prions, and are normal proteins found primarily in a sponge-like tissue. Disease is associated with abnormal versions of prion proteins.

The normal function of prion proteins is unclear, but they are thought to protect critical brain cells from dying. Mice that lack normal prions develop ataxia (coordination problems) that resembles the ataxia of kuru and CJD patients. Prion-free mice develop symptoms at approximately 70 weeks (late middle age for a mouse).

Since proteins are unable to self- replicate, it seemed unlikely that a transmissible disease could be caused by protein alone. Contact between the normal and abnormal forms of protein can cause conformational change from the normal to the flawed form, if the abnormal and normal proteins are sufficiently similar. Encephalitis (inflammation of the brain) can present with similar initial symptoms as the spongiform encephalopathies, most notably ataxia and mental disorientation. Encephalitis can have several causes, some of which are viral infections.

All of the following individuals display symptoms of dementia EXCEPT someone who:

a. cannot do the most rudimentary arithmetic operations.

b. cannot distinguish between the smells of the distinct flowers.

c. displays abrupt change in character.

d. has lost the ability to speak.

e. has tremendous difficulty remembering the days of the week.


According to the passage, which one of the below is a medical condition that is the least likely to be associated with dementia:

a.Alzheimer's disease

b. Familial fatal insomnia

c. Stroke

d. Meningitis

e. Spongiform encephalopathies


Spongiform encephalopathies are different from strokes because spongiform encephalopathies:

a. are more difficult to cure.

b. have more varieties.

c. are less researched.

d. are associated with human brain.

e. are transmissible.

This is an except question
Our goal is to stay AS NEAR AS possible...

"impairment of intellectual function, and can affect memory, emotions, personality, language, judgment, and cognition"

a. cannot do the most rudimentary arithmetic operations.
- arithmetic operations= need cognition

b. cannot distinguish between the smells of the distinct flowers.
-- we are no where given that it will impair the senses of smell ... I guess you thought "judgment" would be fit for this...but the "judgement" is too broad and not specific enough to conclude that it represents"loss of smell sense"..

c. displays abrupt change in character.
- change in character= personality

d. has lost the ability to speak.
= Ability to speak= language

e. has tremendous difficulty remembering the days of the week.
Difficulty remember= memory

i would to add my two cents here, although i am also not sure about the ans why its b as i lag behind with judgement , what i look over such as
intellect= ability to think in most logical way
cognition= process of being knowledge developed in mind
judgement = means making decision from what we have resourced

so i too do not find b as the most suitable ans.
waiting for the committing response......

3 mins and all correct. Not sure if this is actually 700 level or is improperly tagged. Most of the questions ( two out of three) have more than 90% correct attempts in timer statistics. AkshdeepS maybe we need to move it to 600-700 if not sub-600?

Best,
Gladi

That's true Gladi, we need to change it to 600-700 level. But I am not able to move this.
Actually this 700 level was shown in parent source of the passage.

Thanks for pointing this.

workout, Please move the passage to 600-700 level.

Passage has too many details so it's easy to get lost. Make sure to focus on the big picture. Got all Q correct in 7 min including 4:30 min to read the passage!

Passage Map:


1) About Dementia
2) About E disease
3) About P. Protein
4) Transmission

All of the following individuals display symptoms of dementia EXCEPT someone who:[/b]

a. cannot do the most rudimentary arithmetic operations.

impairment of intellectual function

b. cannot distinguish between the smells of the distinct flowers.

Sensory organs especially the sense of smell is not discussed. Note that it doesn't ask one to recall which flower's smell it is etc. It just says "distinguish between distinct smells" - Is this the same smell as that or different.

c. displays abrupt change in character.

impairment of personality

d. has lost the ability to speak.

impairment of language

e. has tremendous difficulty remembering the days of the week.

impairment of memory

Answer (B)
