6 0

Answer:

There are prion-like particles in the brain normally, and when these become abnormal they can cause disease. (Ans. A)

Explanation:

Prions are proteins which can trigger normal proteins to fold abnormally, and they are present in the brain. They are causing many types of neurodegenerative diseases in both humans and animals. Which are known as transmissible spongiform encephalopathies.

Prions can enter the brain with the help of infection, also can arise from the gene mutation that encodes the proteins, and sometimes this affects humans by infected meat.

If a person infected from prion disease, it affects central nervous system tissues like brain, eye tissues and spinal cord.

Lorazepam is commonly given along with a neuroleptic agent. what is the purpose of administering the drugs together?
Nonamiya [84]

Neuroleptics are molecules that act on the nervous system by modulating both agitation and neuronal activity. These drugs have an effect countering the transmission of a neuromediator.

These side effects are numerous, among them there is tardive dyskinesia, including akathisia (a state of agitation, distress, and restlessness). This can be corrected by the administration of benzodiazepines such as lorazepam.
