Overall these key points are so helpful to diagnose the type of dementia in USMLE Clinical Scenarios:

  • Dementia + sensory Ataxia + PNP(polyneuropathy) + UMN(babinski's sign) = B12 deficiency
  • Dementia + cerebellar ataxia + ophtalmoplegia = B1 def (Wernicke's syndrome)
  • Dementia + high cholesterol = hypothyroidism
  • Dementia + myoclonus = Creutzfeldt-Jakob disease
  • Dementia + gait apraxia + urinary incontinence = NPH (non-pressure hydrocephalus)
  • Dementia with stepwise progression + pseudobulbar palsy(PBP) = Binswanger's disease (vascular dementia)
  • Dementia + PBP + gaze abnormality + torticollis = PSP (progressive supranuclear palsy)
  • Dementia + chorea= Huntington's disease
  • Dementia + Parkinsonism + syncopal attack = Shy-Drager syndrome (multiple system atrophy)
  • Dementia that is fluctuating + Parkinsonism= Lewy body dementia
  • Dementia with sparing visuospatial skills + personality change = Frontotemporal dementia
Feel free to add to the list ...

This is the list of what you have mentioned:

  • Dementia + sensory Ataxia + PNP(polyneuropathy) + UMN(babinski's sign) = B12 deficiency
  • Dementia + cerebellar ataxia + ophtalmoplegia = B1 def (Wernicke's syndrome)
  • Dementia + high cholesterol = hypothyroidism
  • Dementia + myoclonus = Creutzfeldt-Jakob disease
  • Dementia + gait apraxia + urinary incontinence = NPH (non-pressure hydrocephalus)
  • Dementia with stepwise progression + pseudobulbar palsy(PBP) = Binswanger's disease (vascular dementia)
  • Dementia + PBP + gaze abnormality + torticollis = PSP (progressive supranuclear palsy)
  • Dementia + chorea= Huntington's disease
  • Dementia + Parkinsonism + syncopal attack = Shy-Drager syndrome (multiple system atrophy)
  • Dementia that is fluctuating + Parkinsonism= Lewy body dementia
  • Dementia with sparing visuospatial skills + personality change = Frontotemporal dementia
  • Dementia secondary to depression = Pseudo-dementia
  • Dementia+ diarrhea+ Dermatitis= pellagra (B3-niacin deficiency)
  • Dementia +visual hallucinations+rem sleep disorder+capgras syndrome-Diffuse lewy body dementia.DD(delirium induced by L-dopa may be initial clue in diagnosis)
