Q

What are the different types of delerium?

A

Delirium tremens
Severe form of the condition experienced by people who are trying to stop drinking

Hyperactive delirium
Characterized by being highly alert and uncooperative

Hypoactive delirium
More common. With this type, you tend to sleep more and become inattentive and disorganized with daily tasks. You might miss meals or appointments

Mixed delerium
Switch between hyperactive and hypoactive states

Q

What is the cause of delerium?

A

When the normal signals entering exiting the brain become impaired

Certain causes include:

  1. Certain medications or drug toxicity
  2. Alcohol or drug intoxication or withdrawal
  3. A medical condition, such as a stroke, heart attack, worsening lung or liver disease, or an injury from a fall
  4. Metabolic imbalances, such as low sodium or low calcium
  5. Fever and acute infection, particularly in children
  6. Urinary tract infection, pneumonia or the flu, especially in older adults
  7. Exposure to a toxin, such as carbon monoxide, cyanide or other poisons
  8. Malnutrition or dehydration
  9. Sleep deprivation or severe emotional distress

Q

How do you diagnose delerium?

A

Confusion Assessment Method (CAM)

  1. Acute onset and fluctuating course
    Is there evidence of an acute change in mental status from the patient’s baseline? Did this behaviour fluctuate during the past day
  2. Inattention
    Does the patient have difficulty focusing attention; for example, being easily distracted or having difficulty keeping track
  3. Disorganized thinking
    Is the patient’s speech disorganized or incoherent; for example, rambling or irrelevant conversation, unclear or illogical flow
  4. Altered level of consciousness
    Overall, how would you rate this patient’s level of consciousness: alert (normal); vigilant (hyperalert); lethargic (drowsy, easily aroused); stupor (difficult to arouse); coma (unarousable)?

Q

What causes alzheimer’s disease?

Q

What are the two proteins involved with alzheimers disease?

A

Plaques
Beta-amyloid is a leftover fragment of a larger protein. When these fragments cluster together, they appear to have a toxic effect on neurons and to disrupt cell-to-cell communication. These clusters form larger deposits called amyloid plaques, which also include other cellular debris.

Tangles
Tau proteins play a part in a neuron’s internal support and transport system to carry nutrients and other essential materials. In Alzheimer’s disease, tau proteins change shape and organize themselves into structures called neurofibrillary tangles. The tangles disrupt the transport system and are toxic to cells

Q

What is the difference between dementia and delerium?

A

Dementia develops over time, with a slow progression of cognitive decline.

Delirium occurs abruptly, and symptoms can fluctuate during the day.

The hallmark separating delirium from underlying dementia is inattention.
The individual simply cannot focus on one idea or task.

  4. A six month period with signs of the disturbance.
