DEMENTIA

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
