Delirium:

  • Not capable of paying attention or concentrating at times
  • Overall thinking is disorganized

Dementia:

  • Attention and concentrate are impaired, but are able to focus and concentrate with proper engagement

Depression:

  • Poor attention and concentration cause pseudo-dementia
  • Can be seen with depression or dementia
  • Dementia: less likely to show emotions and social engagement
  • Depression: more likely to show facial expressions and engage socially
  • Misinterpretation of visual and audio stimuli
  • Common with delirium and dementia
  • Less common with depression

Delirium:

  • Difficulty with speech and understanding
  • Incoherent, nonsense words and syllables
  • Abusive language

Dementia:

  • Gradual impairment of language and understanding

Depression:

  • Slow and sparse language
  • Able to understand and speak

Delirium:

  • Can have frequent fluctuations of symptoms
  • Short duration with treatment

Dementia:

  • Typically gradual decline
  • Can have fluctuations from time to time

Depression:

  • Symptoms do not fluctuate much
  • Treatable

Medical Causes:

  • Nutritional
  • Hormonal
  • Tumor-caused
  • Drug-related
  • Stroke

Alzheimer’s treatment:

  • Combination therapy is more effective
  • Managing behavior symptoms

  • Hormones
  • Selegiline
  • Blockers of plaque and tangles
  • Effectors of brain metabolism
  • Brain cell growth
  • Immunizations
  • Stem cells
  • Risk factors

Behavioral approaches can reduce the frequency or severity of problem behaviors

  • Break down complex tasks
  • Reduce the amount of activity and noise in the environment
  • Offer pleasurable activities

Modifying the environment for safety and comfort
