Are there any other diseases that look a lot like Alzheimer Disease?
There are many diagnoses to consider when a person presents with dementia. Frontotemporal dementia, Picks disease, Parkinson disease, diffuse Lewy body disease, Creutzfelft-Jakob, and CADASIL are important common differential diagnoses for people presenting with symptoms of dementia.
There can be other reasons for a person to have symptoms mirroring dementia too. These other causes include depression, drug abuse, thyroid disease, improper nutrition (B12 and thiamine vitamin deficiency specifically), slight build up of water build up in the brain (hydrocephalus) and disease of the central nervous system.
