4AT score for Delirium Screening


What is Delirium?

Delirium is a mental state which accompanies anxiety, nervousness, discomposure and lack of calmness. It is also related to fever and other problems in the human body. Delirium can be caused due to severe sickness, including, infection, and consumption of particular drugs, or drinking alcohol and similar liquids. However, it can also be brought about by addiction to drugs. Furthermore, the people above the age of 65 years are prone to developing delirium. Those people who have had disease or damage to the brain in the retrospective can also be patients of this disease.


What are its signs?

Delirium has a direct influence on the feelings, emotions, brain, mind, and muscles. If a patient has succumbed to the following things then one should know that he or she is most likely a patient of it:

  • Disturbed sleepiness
  • Lack of concentration
  • Babbling inanely (speaking without thinking)
  • Improper muscles function
  • Short-term memory loss

How is it cured?

We understand how difficult is it to even think about someone having delirium. It is not the end of the world. The 4AT is a tool used for screening in order to know about the quick and delicate information if the person is having any cognitive impairment or delirium. In case if a person gets a score of 4 and above then it will highlight that the delirium is not identifiable. It talks about an analysis of the mental state in order to identify the disease.

However, in the case of the patient getting a score ranging from 1 to 3 then it tells that he or she is having cognitive damage. But, the score talks about further cognitive analysis and details about the person’s past are also required. The score of 1 to 3 is just the score of the patient at that time. Moreover, the score of 4 demands the taking of information from a single source or more than that. For example, it may include personal information about the patient which the doctor, hospital nurses have. The person who is testing must take into consideration the communication problem of the patient, such as, improper hearing, language disorder, etc.


Levels of Alertness

In usual cases, in the hospitals the altered level of alertness is most likely a case of delirium. When a person is having noticeable alertness at the time of analysis at the bedside, then the score will be 4 for it. The Abbreviated Mental Test – 4 (AMT4) can be taken from the complete AMT if it is done right before. There can also be a fluctuating course (acute change), which involves that fluctuation happens without the delirium in a few issues of dementia. But, it usually indicates the delirium.

In order to decipher if the patient is having any hallucinations, then the tester having the 4AT apparatus or tool must ask the patient if he or she can feel or see something which the tester cannot. The tester should also ask the patient if he/she is afraid of someone in the room. Usually, in hospitals, such issues have diagnosed the deliriums and not schizophrenia.
